How does independent assortment increase genetic variation in Meiosis?
Answer:
Independent assortment produce new combinations of alleles.
Explanation:
In meiosis I, crossing over during prophase and independent assortment during anaphase creates sets of chromosomes with new combinations of alleles. Genetic variation is also introduced by random fertilization of the gametes produced by meiosis. It results in gametes that have unique combinations of chromosomes.

Why does the brain of mammals keep track of the temperature of the skin and the blood?
Answer:
The thermoregulatory center in this gland regulates heat loss and production. This center is influenced by nerve impulses from receptors near the skin and the temperature of the blood flowing through it. When the environment is warm or hot, there are a variety of ways mammals stay cool..
Explanation:
Hope it helps you..
Y-your welcome in advance..

The brain of mammals keeps track of the temperature of the skin and the blood so that they can regulate the cells and maintain homeostasis in the body relative to the outer environment.
What is the importance of homeostasis in the body?The body's homeostasis should always be maintained in order to keep the cells and organs active and able to perform their functions. Because the brain has different control centers, it keeps track of the skin and blood temperature because the brain can release different hormones depending on the situation. The lipid composition and arrangements of the cells change in the summer and the winter, and all these are possible due to the brain sending signals to cells.
Hence, the brain of mammals keeps track of the temperature of the skin and the blood so that it can regulate the cells and maintain homeostasis in the body relative to the outer environment.

Based on the data collected and what you have learned about osmosis and the three treatment options, rank the treatments from most effective to least effective. What do you predict?
Although I could not locate the options in order to provide a ranking, I can offer the insight that a hypertonic saline solution will be the most effective form of treatment.
I believe you are referring to the full case study which says :
"Your goal is to stop Clark's seizures by restoring equilibrium between the blood and the matrix. Based on the data collected and what you have learned about osmosis and the three treatment options, rank the treatments from most effective to least effective. What do you predict?"
A hypertonic saline solution is used to draw water out of cells by creating an increased concentration of solute in the blood, forcing the water out of the cell through osmosis.
Clark's seizures may be caused by Increased solute concentrations in the brain which forces water from blood to move into the brain, thus increasing the matrix pressure. This then causes the neurons to fire at an increased rate and leads to the seizures Clark was experiencing.
Hypertonic saline can be used to increase solute concentrations, in this case, Sodium, in the blood which forces water to move back into veins. Thus returning Clark to a balanced level of blood and matrix water levels, and may reduce his likelihood of seizures.

Most of the reactions by which energy from carbohydrates is released for use by the cell take place within the
A) Mitochondria.
B) Nuclei.
C) Ribosomes.
D) Vacuoles
Most of the reactions by which energy from carbohydrates is released for use by the cell take place within the MITOCHONDRIA. These organelles (mitochondria) are the energy centres of the cell.
Cellular respiration is a series of metabolic reactions by which the cell produces energy in the form of ATP by using the energy stored in the chemical bond of simple carbohydrates and oxygen.
Cellular respiration has three stages: glycolysis, the citric cycle and oxidative phosphorylation.
Glycolysis occurs in the cytoplasm, whereas the citric cycle and oxidative phosphorylation take place in the mitochondria.

Hydrophilic, Hydrophobic
Hydrophobic, Hydrophilic
Flexible, Hydrophobic
Water Loving, Flexible
Explanation:
The tails of the cell membrane are __hydrophobic__ while the phosphate heads are __hydrophilic__.
I hope the following image helps to further explain the answer.
The tails of the cell membrane are hydrophobic while the phosphate heads are hydrophilic. The correct option is B.
What is the structure of cell membrane?The phospholipid bilayer, which forms a stable barrier between two aqueous compartments, is the membrane's fundamental structure. These compartments are the inside and outside of the cell in the case of the plasma membrane.
The cell membrane, also known as the plasma membrane, is found in all cells and serves to separate the cell's interior from the outside environment.
The membrane of the cell is composed of a semipermeable lipid bilayer. The cell membrane controls the transport of materials into and out of the cell.
The heads (phosphate) are polar, whereas the tails (lipid) are non-polar. The heads, which form the outer as well as inner linings, seem to be "hydrophilic" (love water), whereas the tails, which face the cell membrane's interior, are "hydrophobic" (water fearing).
Thus, the correct option is B.
