Explain which three marine habitats would have the least access to phytoplankton
Answer:
The three seabed habitats: vents and seeps, trenches and seamounts. The phytoplankton develops in the area exposed to the sunlight to take the elements dissolved in the sea water, including carbon dioxide, to create new cells and are responsible for about half of the inhabitants of the planet of the photosynthesis and production of oxygen. It is found mainly in the surface and lands on the seafloor as dead cells, still carrying the carbon dioxide, while maintaining the balance of oxygen/carbon dioxide in the ecosystem.

A mass extinction event is when over ____ of species die out in a relatively short
period of time.
A. 100%
B. 25%
C. 50%
D. 75%
A mass extinction event is when over 75% of species die out in a relatively short period of time. Therefore, the correct answer is: D. 75%
Earth's biodiversity declines rapidly and widely during an extinction event. A significant shift in the variety and abundance of multicellular organisms indicates such an event. It occurs when both the rate of speciation and the rate of extinction outpace the background rate.
A short period of geological time known as a mass extinction occurs when a significant portion of biodiversity, or distinct species—such as bacteria, fungi, plants, mammals, birds, reptiles, amphibians, fish, and invertebrates—die.
Impacts from comets and asteroid, widespread volcanism, climatic changes, rapid shifts in geography and ocean currents, or a combination of these can all lead to mass extinctions. The extinction of a single species is a characteristic of the flora and fauna of Earth.

describe the effects on surface area of potato of cutting the potato sticks into eight pieces
The effects of cutting the potato sticks into eight pieces would increase the surface area of the potato, and having more surface area means more area for enzymes to interact with the potato so it can be cooked easily.
What is the significance of the increased surface area of the potato?When the potato is cut into eight pieces, the surface area increases, and as the surface area increases, the cooking time decreases because the enzymes are exposed and can be deactivated when exposed to heat. So vegetables are cut before cooking.
Hence, effects of cutting the potato sticks into eight pieces would increase the surface area of the potato, and having more surface area means more area for enzymes to interact with the potato so it can be cooked easily.

1. When do pioneer species arrive during primary succession?
A. Last ones to appear in an ecosystem with no soil present
B. First ones to appear in an ecosystem with no soil present
C. Appear in an ecosystem during the middle of primary succession
D. Appear in an ecosystem during the middle of secondary succession
Answer: B. First ones to appear in an ecosystem with no soil present
Explanation:
Primary succession is the process of claiming a previously barren area for living organisms. The area would have no soil and would just be full of rocks having been recently unearthed as a glacier retreated or a lava flows cooled down.
Pioneer species are the first to appear in such an environment. They are able to live on the rocks and sustain themselves. In time, they break down the rocks into soil so that plants are able to grow. Examples of such species include lichens and fungi.
This reaction is used in the brewing industry.

In those parts of equatorial Africa where the malaria parasite is most common, the sickle-cell allele constitutes 20% of the b hemoglobin alleles in the human gene pool. In the United States, the parasite that causes malaria is not present, but African-Americans whose ancestors were from equatorial Africa are present. What should be happening to the sickle-cell allele in the United States, and what should be happening to it in equatorial Africa
Answer:
directional selection, stabilizing selection
Explanation:
Directional selection is a type of natural selection that favors one extreme phenotype over other phenotypes, thereby modifying allele frequency in the direction of the favored phenotype. This type of positive selection is the main cause of phenotypic diversification. In the USA, the environment created a selection pressure that favored individuals that don't have the defective sickle-cell allele, thereby reducing its frequency in this population. Stabilizing selection, also known as balancing selection, is a type of natural selection where the most common phenotype is selected in the population, thus predominating in future generations. In equatorial Africa, the defective sickle-cell allele is present in a high frequency because individuals that are heterozygous for this allele are less susceptible to malaria, and therefore balancing selection should maintain this allele in the African population.
SOMEONE PLEASE HELP ME THIS IS DUE TONIGHT!!!! Mammalian mothers develop strong attachments with their young. In a mouse, this attachment process can be broken down into the following steps:
1. The mother mouse experiences certain hormonal changes when her babies are born.
2. Newborn infants show attachment behavior toward the mother.
3. Hormonal changes related to the birth process and attachment behavior from the infant stimulate oxytocin release in the mother.
4. Oxytocin stimulates the mother to display parenting behavior toward the babies.
5. This parenting behavior stimulates oxytocin release in infant brains.
6. Babies suckle milk from the mother, which stimulates more oxytocin release in the mother.
Draw a flowchart or diagram to describe how oxytocin concentration impacts the attachment between mothers and their young.. Explain whether feedback is taking place in this example.
The mother or infant's oxytocin release boosts the other's, strengthening their bond. The feedback loop promotes care and bonding between mother and offspring, which is vital to their survival.

What
happens once a neurotransmitter is received by a post synaptic neuron receptors
Answer:
Neurotransmitter binding increases membrane permeability and form a new action potential.
Explanation:
Neurotransmitters are specific lipid-based compounds that are used in the nervous system in chemical signal transduction. They exhibit receptor-specific functions in triggering many regions and physiological responses of the brain and spinal cord or the central nervous system (CNS).
When released into the space between the synapses called the synaptic cleft, they trigger a range of responses. On the postsynaptic cells they briefly bind to chemical receptors. This results in changes to the membrane which increases the cells' permeability to ions like Na+; a new action potential is created.
