A population of 150 individuals has an allele frequency of 0.2 for the dominant allele (H) and a frequency of 0.8 for the recess
Amanda [17]
Hardy-Weinberg Equation (HW) states that following certain biological tenets or requirements, the total frequency of all homozygous dominant alleles (p) and the total frequency of all homozygous recessive alleles (q) for a gene, account for the total # of alleles for that gene in that HW population, which is 100% or 1.00 as a decimel. So in short: p + q = 1, and additionally (p+q)^2 = 1^2, or 1
So (p+q)(p+q) algebraically works out to p^2 + 2pq + q^2 = 1, where p^2 = genotype frequency of homozygous dominant individuals, 2pq = genotype frequency of heterozygous individuals, and q^2 = genotype frequency of homozygous recessive individuals.
The problem states that Ptotal = 150 individuals, H frequency (p) = 0.2, and h frequency (q) = 0.8.
So homozygous dominant individuals (HH) = p^2 = (0.2)^2 = 0.04 or 4% of 150 --> 6 people
Heterozygous individuals (Hh) = 2pq = 2(0.2)(0.8) = 0.32 or 32% of 150
--> 48 people
And homozygous recessive individuals (hh) = q^2 = (0.8)^2 = 0.64 = 64% of 150 --> 96 people
Hope that helps you to understand how to solve these types of population genetics problems!

What are the basic cell structures that impacts diffusion?
maria [59]

I only know one for the first one, don't be mad, please.

1. I'm pretty sure one of them is membrane

2. A cell can die through infection, poisoning, overheating, or even lack of oxygen.

3. I think it depends on how fragile the membrane of the cell is.

I'm so so so sorry if these didn't help, I'm trying my best, lol.

Explain how the structure of compact bone relates to its function.
natka813 [3]

Answer:

Explanation:

Compact bone aka cortical bone is a dense, solid and rigid in which bony matrix with ground org. Substances and salts densely filled and leave tiny spaces known as lacunae. These spaces contain osteocytes also called as bone cells. Inside of these osteons there is a central canal which supplies blood vessels and nerves within bone. These vessels provide blood to the spongy bone and living cells housed within compact bones.

Structure of Compact bone: Basic unit of Compact bone is called osteon also known as haversian system. Each osteon consist of four parts.

1. Haversian canal which consists blood vessels and nerves acts as a site of hematopoiesis which is one of the functions of Compact bone.

2.lamellae are concentric rings of strong matrix consisting Calcium and phosphorus. this gives the bone its strength and hardness to bear body weight.

3.Lacunae contains osteocytes.

4.Canaliculi links osteocytes and provide route for nutrients to reach osteocytes.
