You learned in the reading that some symbiotic relationships are helpful and some are harmful. Look at the symbiotic relationships listed below and select all where at least one organism is harmed (the reading calls these harmful relationships). Group of answer choices Commensalism Parasitism Mutualism Predator-Prey Competition
Answers
Answer: Parasitism, Predator-Prey, Competition
Explanation:
The symbiotic relationship is the relationship in which two distinct species are associated with each other. In the symbiotic relation the species may get harm or benefit of association. Parasitism can be defined as the symbiotic relationship in which one species get harmed and other one receives the benefit. For example, malarial parasite plasmodium derives the nourishment from the host body (human). Predator-prey relationship is also harmful as the predator kills the prey to obtain it as food. Competition is harmful in the sense two or more organisms of the same or different species compete for the same resource, the most dominant receives the resource the inferior organism is either killed or harmed in the fight for resources.

Please explain the health principles that are practiced by Rastafarians in Trinidad and Tobago and how this information prepares you as a nurse to better serve this community.
Answers
Answer:
Rastas, as members of the movement are called, see their past, present, and future in a distinct way. Drawing from Old Testament stories, especially that of Exodus, they “overstand” (rather than understand) people of African descent in the Americas and around the world to be “exiles in Babylon.” They believe that they are being tested by Jah (God) through slavery and the existence of economic injustice and racial “downpression” (rather than oppression). Looking to the New Testament book of Revelation, Rastas await their deliverance from captivity and their return to Zion, the symbolic name for Africa drawn from the biblical tradition. Ethiopia, the site of a dynastic power, is the ultimate home of all Africans and the seat of Jah, and repatriation is one goal of the movement. Many (though not all) Rastas believe that the Ethiopian emperor, His Imperial Majesty Haile Selassie I, crowned in 1930, is the Second Coming of Christ who returned to redeem all Black people. The movement takes its name from the emperor’s precoronation name, Ras Tafari.

It is the total amount of organic matter produced by the plants that is available to the herbivores in an ecosystem. NPP = GPP - Respiration losses Therefore, the given statement "the amount of energy made available by plants to other organisms is referred to as productivity" is correct.
The amount of energy made available by plants to other organisms is referred to as productivity. Productivity is the amount of biomass produced per unit area per unit time in an ecosystem. Productivity can be calculated through two types: Gross Primary Productivity (GPP) and Net Primary Productivity (NPP).Gross Primary Productivity (GPP): It is the total amount of organic matter produced by the plants through photosynthesis in a given period of time. GPP is the total photosynthetic rate of all the producers in an ecosystem. GPP
= NPP + Respiration losses Net Primary Productivity (NPP): It is the amount of organic matter produced by plants after accounting for the respiration losses from GPP. It is the total amount of organic matter produced by the plants that is available to the herbivores in an ecosystem. NPP
= GPP - Respiration losses Therefore, the given statement "the amount of energy made available by plants to other organisms is referred to as productivity" is correct.

if a population leaves hardy-weinberg equilibrium due to selection how does it return to hardy-weinberg equilibrium?
Answers
a population leaves Hardy-Weinberg equilibrium due to selection it can return to the equilibrium by . 1. A large population size 2. No migration (immigration or emigration) 3. No mutation (change in DNA sequence)4. No natural selection 5. Random mating (no selection for mates).
Hardy-Weinberg equilibrium assumes that there is no selection for or against any genotype in the population. In reality, this is rarely the case. If a population's genotypic frequencies deviate from Hardy-Weinberg equilibrium, selection may be one cause.
There are two types of selection: directional selection and stabilizing selection. If a population's genotypic frequencies deviate from Hardy-Weinberg equilibrium, selection may be one cause.
Stabilizing selection occurs when the average genotype is favored over the extremes. In this case, both the favored and disfavored alleles decrease in frequency. There are a few potential scenarios in which a population might return to Hardy-Weinberg equilibrium after leaving it due to selection:
1. If the selection pressure is removed, the population may return to Hardy-Weinberg equilibrium.
2. If the favored allele reaches 100% frequency, the population will return to Hardy-Weinberg equilibrium because there will no longer be any variation in the population.
3. If a new mutation occurs and creates a new allele, the population may return to Hardy-Weinberg equilibrium if the new allele is neutral and does not confer a selective advantage or disadvantage.
4. Finally, if gene flow (migration) is introduced into the population, it may return to Hardy-Weinberg equilibrium.

Answers
The type of white blood cell that is phagocytic, has a segmented nucleus, and accounts for 60-65% of all wbcs is called a neutrophil.
A type of immune cell that can surround and kill microorganisms, ingest foreign material, and remove dead cells. It can also boost immune responses. Monocytes, macrophages, and neutrophils are phagocytes. A phagocyte is a type of white blood cell.
Phagocytes are a type of white blood cell that use phagocytosis to engulf bacteria, foreign particles, and dying cells to protect the body. They bind to pathogens and internalise them in a phagosome, which acidifies and fuses with lysosomes in order to destroy the contents.
They are a key component of the innate immune system. There are three main groups of phagocytes: monocytes and macrophages, granulocytes, and dendritic cells, all of which have a slightly different function in the body.

Some insect species are resistant to pesticides. Which statement BEST explains this phenomenon? Natural selection resulted in an unfavorable variation for the insects. Because their survival depended on it, the insects developed variations that made them resistant to poisons. Random variation in the population led to a population with a favorable adaptation. Some of the insects became instantly immune when the poisons were introduced into their environment
Answers
Answer:
Random variation in the population led to a population with a favorable adaptation
Explanation:
Insecticide resistance can be defined as an evolutionary process that causes a decreased susceptibility of an insect population to a particular insecticide. The evolution of the insecticide resistance occurs by the mechanism of natural selection, where most resistant insects survive and thus pass on their acquired heritable resistance to their offspring. Moreover, the evolutionary origins of the resistance trait may be associated with different processes: 1-de novo mutations (i.e., the emergence of beneficial genetic changes in the population), 2-standing variation in the original population which is selected under the selective agent (in this case, the pesticide), 3-migration of resistant specimens originally resistant to the pesticide, and 4-even interspecific transfer (i.e., horizontal transfer between different species).

The electric charge density is distributed symmetrically in a cylinder infinitely long in the z-direction. The charge density is given by the expression
Answers
The electric charge density of a cylinder infinitely long in the z-direction is symmetrical, and is given by the expression ρ(r) = A/r2, where A is the total charge and r is the distance from the z-axis. The charge density, ρ, is measured in coulombs per meter squared (C/m2).
The electric charge density in a cylinder that is infinitely long in the z-direction can be represented by the expression:
ρ = λ / (2πr)
where ρ is the charge density, λ is the linear charge density, and r is the radius of the cylinder.
The charge density is distributed symmetrically in the cylinder, meaning that it is the same at every point along the z-axis. This is because the charge density is only dependent on the radius of the cylinder, and not on the position along the z-axis.
The charge density expression can also be written in terms of the electric field, E, as:
ρ = ε₀E / (2πr)
where ε₀ is the permittivity of free space. This expression relates the charge density to the electric field in the cylinder. The electric field is also distributed symmetrically in the cylinder, as it is only dependent on the radius of the cylinder and not on the position along the z-axis.

How is most ATP formed during respiration?
Answers
Most of the ATP produced by aerobic cellular respiration is made by oxidative phosphorylation
Oxidative phosphorylation is responsible for the majority of the ATP generated by aerobic cellular respiration. Protons are pumped through a membrane to produce a chemiosmotic potential using the energy released. Then, ATP synthase is engaged by this potential to synthesis ATP from ADP and a phosphate group. During aerobic respiration, glucose and oxygen combine to produce ATP, which the cell can utilise. As products, water and carbon dioxide are produced. In the general equation for aerobic cellular respiration, glucose and oxygen combine to create ATP. Oxidative phosphorylation is the biochemical cycle that generates a most net ATP per molecule of glucose. The majority of ATP synthesis takes place during cellular respiration in the mitochondrial matrix, producing about 32 ATP molecules for every glucose molecule.

Which hormone would NOT be produced if you blocked the activity of 5-alpha- reductase? Select one: a. Testosterone b. Estradiol c. Progesterone d. DHT
Answers
DHT. Blocking the activity of 5-alpha-reductase would prevent the conversion of testosterone into DHT, so DHT would not be produced.
Testosterone is the main ans, as it is the hormone that is converted into DHT by 5-alpha-reductase. Estradiol and progesterone are not directly affected by 5-alpha-reductase activity.
5-alpha-reductase is an enzyme that converts testosterone into dihydrotestosterone DHT. If you blocked the activity of 5-alpha-reductase, DHT production would be inhibited, while the production of the other hormones listed testosterone, estradiol, and progesterone would not be directly affected.

algae → snails — crabs — salmon → man
b) Because killer whales are at the top of many food chains, it may seem as if they
are not at risk of starving if seals die off. Why is this not necessarily true? (2 points)
Answers
Answer:
a) Higher carbon dioxide levels means a rapid growth of Algae, especially toxic blue-green algae that can float to the surface of the water. This growing amount of Algae will expand across the ocean and clutter it. Harmful algal blooms can be harmful to aquatic life, as some produce toxins that can make animals sick, while others can die off in large quantities and deplete oxygen in the water when they decompose. Snails, specifically aqaurium snails, crabs, and salmon do feed on Algae, which could control it to a degree. However, as the ocean becomes more acidic, it could dissolve the shells of crabs and snails, which will cause them to cook in the sun, and therefore die out. As for salmon, studies showed that high CO2 concentrations disturb fish acid-balance, induce stress response, increase nephrocalcinosis incidence, energy metabolism, and feed conversion ratio, and reduces body condition factor, feed intake, and growth. Fish in this condition are very vunerable to dying despite food being all around them. Additionally, fish in those conditions are not suitable for consumption, which means less food for mankind.
b) This is not true. Although they eat sharks, whales, and dolphins, that is just occasional. Seals are their primary meal. As the killer whale is a consumer, it cannot provide food/energy for itself, therefore relying on organisms below it on the food chain. The killer whale predominately consumes seals, being it’s only large predator, killer whales are crucial to the stabilisation of seal population.

when a nerve cell repolarizes after firing a nerve impulse, it does so by using which of the following?***bubble both that apply***
Answers
When a nerve cell repolarizes after firing a nerve impulse, it does so by using the Sodium-potassium pump and Potassium ion channels.
The resting membrane potential (-70mV) inside a neuron is maintained by the Na⁺ / K⁺ pump. Sodium ions are pumped out of the neuron and potassium ions are pumped in. This maintains the concentration gradient of sodium and potassium ions across the cell membrane. During depolarization, the sodium ion channels open, allowing sodium ions to flow into the neuron. As a result, the membrane potential increases (becomes less negative).
At the peak of the action potential, the sodium ion channels close and the potassium ion channels open, gthis allows potassium ions to flow out of the neuron, repolarizing the cell. The repolarization phase restores the original concentration gradient of sodium and potassium ions across the cell membrane. So therefore, the repolarization of a nerve cell after firing a nerve impulse occurs by the flow of potassium ions through potassium channels and also by the use of the sodium-potassium pump.

Answers
Answer:
Clear-cutting the rainforest
Explanation:
Density-independent factors of a population are factors that limit the size of a population irrespective of the density of the population.
A limited food source can only be defined by the size of a population, diseases will spread faster in high-density populations, and an increase in the population of a predator will cause a decrease in the population size of the predator's prey.
Clear-cutting of the rainforest means automatic destruction of the habitat of the poison dart frog's population, no matter the population size. Hence, clear-cutting of the rainforest is considered as the density-independent factor in this case.

if a species has 10 chromosomes in each of its gametes, then how many different chromosomal combinations are possible during gamete production?
Answers
If a species has 10 chromosomes in each of its gametes. There are 25 different chromosomal combinations are possible during gamete production.
The number of diploid chromosomes is 10.
Therefore, the number of haploid chromosomes will be = 10/2= 5.
When n is the haploid chromosome number, the number of potential chromosomal combinations is given by= 2n.
Therefore, 25 chromosomal pairs are required for a diploid chromosome number of 10.
The proper response is hence "25."
A cell of an organism is said to be diploid if it contains two full sets of chromosomes, one from each parent, and both sets are present in equal numbers.Since humans are diploid, the majority of their cells have 23 pairs of chromosomes.
An animal or plant's reproductive cell is called a gamete. Animal sperm and ova (or egg cells) are the names for the male and female gametes, respectively. As haploid cells, sperm and ova have just one copy of each chromosome in each cell. When a sperm and an ovum come together during fertilisation, a new diploid organism is produced.
