To calculate the frequency of the heterozygote genotype (Pq) for this gene we must use the Hardy-Weinberg equation ( p2 + 2pq + q2 = 1 ). This equation relies on the Hardy-Weinberg principle, a model in population genetics that states that the frequency of the alleles in a population is never changing, only the combinations (the genotypes) are changing.
If there are only two alleles (variations) of this gene in a population, then their frequencies should add up to 1 (100%). From this, we can calculate the frequency of the q allele.
p +q=1
0,3 +q=1
q= 1-0,3
q= 0,7
Now hat we have the frequency of the q allele we can use the HW equation to calculate the frequency of the heterozygotes.
0,09 + 2pq +0.49= 1
2pq +0,58= 1
2pq= 1-0.58
2pq=0,42
The freqency of the heterozygotes in this population is 0.42
Answer:
A
Explanation:
It allows the cell to control what materials enter and leave.
The bulky shape of fat cells makes them ideal for filling spaces of connective tissue. The fat cells represent a type of connective tissue.
The adipose tissue is a type of connective tissue composed of fat cells known as adipocytes.
These cells (adipocytes) are specialized cells that store fats, which can be produced by the human body or obtained from the diet.
The shape of the adipocytes can be spherical, oval, polyhedral (as part of adipose connective tissue), etc.

Answer:
B. They all have the same genes but some have hair and some don't
Explanation:
Type I genes tend to be involved in immune response or sensory receptors while type III genes are involved in cell to cell signalling and type II genes are a complex mix of all three types.
Answer:
At the bottom you have the producers aka auto trophic livings (which use inorganic compounds to grow, produce energy, matter and so on..). These organisms would be plants, Cyrano bacteria, over all any organisms that do photosynthesis.
