Due to the tissue loss, a distinct line of bare white skeleton developed, which is how the disease got its name. The reef's food source changes when the corals are removed, changing the species makeup totally.

A bacterial condition called the “white plague” is frequently mistaken for coral bleaching. According to recent investigations, the sickness comes in many forms. Corals lose tissue in every situation, exposing their exposed, raw, white skeleton.

Coral illnesses can spread through a variety of routes, including direct contact, water- or vector-borne transmission, and the relative weights of these routes can vary over time and across geographical areas and disease systems.

Therefore, A solid indication that an infection is present is if your band cell count is more than 10%. To identify the underlying cause of your bandemia, your doctor will advise more diagnostic procedures.

Answer:

the man would have type B blood

the women would have type A blood

Explanation:

In the given question, the genotype of the parents are :

- One parent is Heterozygous for A

- Other parent is heterozygous for B

Blood is made up of Red Blood Cells, White Blood Cells and Plasma.

There are majorly four type of Blood Groups such as:

- Blood Group A

- Blood Group B

- Blood Group AB

- Blood Group O

Blood group AB doesn't contain any antibodies and thus they lack antigens and couldn't donate it to any other blood group.

Thus AB is a Universal Acceptor.

Blood Group O does not contain any antigen and thus it is the Universal donor.

Genotype simply means version of DNA sequence that an individual has. There is a large amount of variation in DNA sequencing among individuals and these sequencing when applied to an individual gene are called as genotype.

Genotype can also be used to refer to the alleles or variants an individual carries in a particular gene or genetic location.

The number of alleles an individual can have in a specific gene depends on the number of copies of each chromosome found in that species, also referred to as ploidy.

Allele is defined as the variant of a given gene.

In genetics it is normal for genes to show deviations or diversity and all alleles together make up the set of genetic information that defines a gene.

In the given question the genotype of the first child would be IAIO and for the second child it is IB IO. For the third child, it is IAIB and the fourth child would be having IO IO.

As children inherit one allele from each parent, these genotypes are possible only when the genotype of parents is IAIO i.e. heterozygous for A and IB IO heterozygous for B.

Thus one parent is Heterozygous for A and other parent is heterozygous for B.

Answer:

Some populations will expand while others decline.

Explanation:

The populations in the environment will probably be impacted as the climate changes, the rainy seasons shorten, and water becomes more scarce. While some that are less suited may have a lesser probability of surviving, the organisms that are more acclimated to the new conditions will have a higher likelihood of survival and reproduction.

The size of the populations in the ecosystem will alter as a result of this shift in the environment's impact on population dynamics. The size of certain populations may expand because they are more suited to the new circumstances, while the size of other populations may decrease because they are less adaptable. Given that the environment would change as a result of this scenario, it is important to note that no change in the equilibrium of each population is not likely to occur.

When conducting an experiment, variables must be identified. Controlled variable: Breakfast time, 7:30 am. Constants: Nomal Glucose level before breakfast. Glucose level when Failing feedback mechanism. Chamical X effect. Trends on the explanation.

This variable is not affected by any other one but influences or causes a reaction in other variables.

Its response might be either directly proportional or inversely proportional to the change in the independent variable.

Unlike the independent variable, the controlled variables do not influence the results.

These variables do not affect the response of the dependent variable.

In conclusion, the independent variable changes and influences the dependent variable, which depends on the first one. Controlled variables are all the remaining variables that are kept constant.

In the exposed example, you want to test the effect of time on blood glucose levels.

Firstly, It's Amino acids. And moving to the answer now. This contains the hydrogen atoms, the carboxylic group, and the amine group.

A basic amino group (NH2), an acidic carboxyl group (COOH), and a specific organic R group (or side chain) are the three organic molecules that make up an amino acid. Alpha-amino [alpha-amino] carboxylic acid is referred to as an amino acid informally. An amino and a carboxyl group are both joined to the core carbon (C) atom, known as the -carbon, in every molecule. A hydrogen (H) atom and the R group typically fulfill the remaining two bonds of the -carbon atom. The building components of proteins are amino acids.

Answer:

The Cell Cycle | Back to Top
Despite differences between prokaryotes and eukaryotes, there are several common features in their cell division processes. Replication of the DNA must occur. Segregation of the "original" and its "replica" follow. Cytokinesis ends the cell division process. Whether the cell was eukaryotic or prokaryotic, these basic events must occur.

Cytokinesis is the process where one cell splits off from its sister cell. It usually occurs after cell division. The Cell Cycle is the sequence of growth, DNA replication, growth and cell division that all cells go through. Beginning after cytokinesis, the daughter cells are quite small and low on ATP. They acquire ATP and increase in size during the G1 phase of Interphase. Most cells are observed in Interphase, the longest part of the cell cycle. After acquiring sufficient size and ATP, the cells then undergo DNA Synthesis (replication of the original DNA molecules, making identical copies, one "new molecule" eventually destined for each new cell) which occurs during the S phase. Since the formation of new DNA is an energy draining process, the cell undergoes a second growth and energy acquisition stage, the G2 phase. The energy acquired during G2 is used in cell division (in this case mitosis).

Naturally occurring hormones affect plants as they speed up the growth of plant cells, ripen fruits, and prevent plants from being eaten by insects, which is the last option.

Naturally occurring hormones in plants, also known as plant growth regulators, play a crucial role in regulating various physiological processes in plants. There are five main types of plant hormones: auxins, gibberellins, cytokinins, abscisic acid, and ethylene. Each of these hormones affects plant growth and development in different ways. Auxins, for example, are primarily responsible for cell elongation and the promotion of lateral growth in shoots. They also play a role in root growth and phototropism, which is the movement of plants towards or away from light sources.

Hence, naturally occurring hormones affect plants as they speed up the growth of plant cells, ripen fruits, and prevent plants from being eaten by insects, which is the last option.

Solution :

In Gizmo experiment, when both the intensity of light and carbon dioxide level is high, the rate of photosynthesis will maximize.

A). If the temperature is too hot or cold, it becomes difficult to find the ideal intensity of light because if the temperature is hot, the light intensity will be too high and thus the chlorophyll will get damaged. While if it too low, then it will be difficult for the proper functioning of the cells. And hence the photosynthesis will not take place.

B). It will be considered as a limiting factor if the light intensity is low. With light intensity being low, it will be difficult for the plant for survival and ideal carbon dioxide level will have no role. This amount of carbon dioxide does not help the plant to survive as the light intensity is now a rate limiting factor.

Secondary succession is the kind of succession that might develop in a neighborhood park after the Zombie Apocalypse if the grass wasn't cut anymore and pioneer species would first colonize the bare soil.

Thus, pioneer species like weeds and grasses would colonize the bare soil and disturbed regions in the initial stage of secondary succession. These species can swiftly adapt to a new habitat since they are frequently resilient and rapidly developing.

In secondary succession, the pioneer species are the early settlers multiply and spread, the soil conditions become more stable and draw in additional species like shrubs and tiny trees. These animals are modifying the environment in a way that makes it possible for bigger and more diversified populations of creatures to live in more complicated settings.

What are Air Masses:  They large volumes of air that have generally the same temperature and pressure.

How they work: One is heated by an electrical current, the other is not. As air flows across the heated wire, it cools down.

Example of an Air Mass: The air masses in and around North America include the continental arctic, maritime polar, maritime tropical, continental tropical, and continental polar air masses. Air is not the same everywhere.

Fact: Unstable air masses have different temperatures and pressures.

How they are formed: An air mass forms whenever the atmosphere remains in contact with a large, relatively uniform land or sea surface for a time sufficiently long to acquire the temperature and moisture properties of that surface.

*** The Earth's major air masses originate in polar or subtropical latitudes.

Idiopathic thrombocytopenic purpura or ITP is also known as Immune thrombocytopenic purpura that is a disorder in which there is an abnormality in the clotting of blood due to a decreasing number of platelets in an individual.

Platelets plays role in clotting the blood to prevent bleeding so this disorder leads to easy bruising, bleeding gums, and internal bleeding. It is an autoimmune disorder as in this case, an immune reaction takes place against one's own platelets.

It occurs in all age and sex groups however, it occurs normally in young children and females more often.

The geochemical cycle that is least likely to be affected by global warming is the water cycle, because even as temperatures increase, the evaporation cycle will remain the same.

With this information, we can conclude that the water cycle, also known as the hydrological cycle, refers to the continuous movement that water makes through the physical environment and the living beings of the ecosystem, passing through the atmosphere, hydrosphere, lithosphere and biosphere.

The length of each cell  in the eyepiece division is option B which is  40 μm

In a microscope, the eyepiece graticule is a scale located in the eyepiece that helps to measure the size of microscopic objects. The stage micrometer, on the other hand, is a calibrated scale on the microscope stage that is used to calibrate the eyepiece graticule.

To determine the value of each eyepiece division on the stage micrometer, we use the following formula:

Value of each eyepiece division = (Value of each stage micrometer division) x (Number of stage micrometer divisions per eyepiece division)

The calculation can be done using the formula:

Length of one eyepiece division = (Length of one stage micrometer division) x (Number of stage micrometer divisions per eyepiece division)

Length of one eyepiece division = 10 μm x (16/40) = 4 μm

Since 4 cells fit across 40 divisions of the eyepiece graticule, the length of each cell is:

Length of each cell = Length of one eyepiece division x 4 = 4 μm x 4 = 16 μm

Therefore, the answer is B) 40 μm by calculating the value of each micrometer.
