one gene in a population of snails determines whether they are poisonous. being poisonous (P) is dominant over not being poisono
Harlamova29_29 [7]

Answer:

F (pp) = 0.04

F (Pp) = 0.32

F (PP) = 0.64

Explanation:

Studying population genetics, we used the Hardy-Weinberg equilibrium model. In the case of snails, the H-W principle predicts that the total number of cases in the population should follow the following equation: PP + 2.Pp + pp = 200.

If a population has 200 snails and 8 are affected by a recessive condition, we have 4% affected, or 0.04.

This means that 0.04 corresponds to p², and p corresponds to 0.2.

Therefore, P is equal to 0.8 because p + P = 1.

Knowing the allele frequencies, we go to the frequency of the genotypes.

F (pp) = p² = 0.04 = 8 snails

F (Pp) = 2.Pp = 0.32 = 64 snails

F (PP) = P² = 0.64 = 128 snails

laiz [17]
The appropriate response is water. An assortment of substances that are not dissolvable in polar solvents, for example, water, but rather will break up in nonpolar solvents, for example, benzene and chloroform. Lipids incorporate triglycerides, phospholipids, steroids, and waxes. 
Fats and lipids are extensive natural atoms which are utilized for vitality stockpiling and which make up the which make up the lipid bilayer of the plasma film of cells. Lipids have hydrophobic tails which are made out of chains of hydrocarbons and hydrophilic heads which are made out of a carboxyl gathering.

AnnyKZ [126]

The answer is;

Both plant and animal cells have a nucleus, where DNA replication takes place.

Cellular respiration does not take place in the ER but in the mitochondria present in both plants and animals.

Only plant cells have cell walls, Animals cells have only the cell membrane

Plants cells have a cell vacuole while animals cells do not.

How are homeostasis and cellular respiration mutually dependent on one another?
Arturiano [62]

Cellular respiration describes the process of oxygen and glucose and converting into water and carbon dioxide. Homeostasis is a term which refers to biological processes in which living things must maintain stable and equal conditions for survival. Cellular respiration which uses oxygen and glucose must be able to sustain life by releasing energy which is called ATP, the ATP which is produced enables many biological processes that keeps organisms alive. Cells need energy to grow, move, and function. The process of homeostasis enables cellular respiration to produce enough molecules which can sustain the development of the cell. Without homeostasis cellular respiration would cease to function and without cellular respiration the process of homeostasis would not occur. Homeostasis regulates how much molecules have to be expended in order to produce energy for the process of cellular respiration.
