Which of the following correctly describes Anaphase?
A. Mitotic spindle attaches to the chromosome's centromeres and lines them up in the middle of the cell.
B. Chromosomes split and move to opposite sides of the cell, the cell elongates
C. Centrioles move to opposite sides of the cell, nuclear envelop dissolves, chromosomes form
D. The Cytoplasm splits, forming two daughter cells
Anaphase is the phase of the mitotic and meiotic cell division. In this phase of the cell division, chromosomes split and move towards the opposite poles. Thus, option B is correct.
What is anaphase?Anaphase is the third stage of cell division, preceded by the prophase and the metaphase. In this stage, the chromosomes aligned before start splitting and move towards the opposite poles of the cells. This causes the cell to elongate and prepares itself to divide in the next step.
Therefore, in anaphase, the aligned chromosomes start splitting.

if the alle B represents black fur and
alle b represents white fur what would be the genotype of animal with white fur
Answer:
The genotypes would have to be "bb".
Explanation:
If the dominant allele B is present in a genotype (a genotype is the two letters to represent the trait) then the organism will always be black.
BB= black
Bb= black
bb= white. This is because there is no "B" to dominate the genotype.

In humans, ventilation, digestion, and blood flow are important biological processes. Explain the relationship between the structure of tissues or organs and one of these processes.
Answer:
I am assuming the question is asking how do the processes relate to one another.
Explanation:
Ventilation happens in the lungs, where carbon dioxide and oxygen are exchanged in the alveoli. This is done via cappilaries that surround the alveoli. Cappilaries are small blood vessels, which are collecitelvy part of the blood flow system (circulation) of the body. In reguards to the digestion, there are capillaries in the vili (which are tiny finger-like structures) so that they can pick up the nutrients during digestion. Another way blood flow and digestion are connected is because the stomach is a muscle, thus is moves and requires energy. That energy comes from the oxygen and nutrients that is supplied by the blood. These are just some examples.

Carbohydrates are an example of a biological macromolecule. The structure of a biological macromolecule affects the function.
Identify the type of chemical bond in carbohydrate polymer. Describe the directionality in carbohydrates and explain how changes in the structure can affect the function.
Answer:
The functional groups determine the shapes of macromolecules and this in turn determines their functions.
Functional groups affect the bonds that hold a macromolecule together. For example, the ring forms of glucose in starch and cellulose have different configurations. As a result, cellulose and starch serve different purposes.
Functional groups also affect the polarity of the bonds. Lipids consist of hydrophilic heads (red) and hydrophobic tails (black and white). This characteristic of lipids allows them to form bilayers, which serve as membranes of cells.
Proteins have complex structures caused by interactions between the functional groups. A change of a single amino acid can make a major change in the function of a protein.

Describe the process of germination and plant growth you observed in the lab activity for a monocot plant.
Answer:
Germination is the process by which a plant develops from a seed. The most common example of germination is a sprout of a seedling emerging from the seed of an angiosperm or gymnosperm. However, the development of a daughter spore from a spore, such as the growth of a mycelium from a fungal spore, is also germination. Therefore, germination can be understood in the general sense as anything that becomes larger from a small entity or a living organism, is a commonly used method in many seed development projects. alike.
