Explanation:
Hi! :)
Make a = q, aa (homozygous recessive) = q^2,
A = p, AA (homozygous dominant) = p^2, and
2pq = heterozygous
This was derived from p + q = 1
Therefore all a in pop (q) = 20% = .20
And all A in pop (p) = 80% = .80
Since the disease is homozygous recessive (affected), then aa = qq or q×q = q^2
q^2 = (.20)^2 = .040 = 4%
Answer: 4%
Hypothesis- introduced evolution before Darwin, two big theories; use or disuse and acquired characteristics
Answer: Valves in the veins
Explanation: The flow of the blood inside the body takes place through the veins and arteries. The oxygenated blood from the heart is supplied to the different parts of the body.
The blood flows from the capillaries to the venules and from there to the veins. The blood moves in the veins by the rhythmic movement of the smooth muscles in the body.
Most of the blood moves against the gravity so there is a chance that it can backflow so to prevent this there are valves in the veins known as one way valves.
Answer:
The skin has 4 main layers, Epedermis, Derma, Hypodermis, and the Subcutaneous layer. Each layer is composed of certain material and tissue. On the most outer layer, there is hair, nerves, and glands (of sweat). Down further are veins, and arteries. The adipose tissue makes up the hypodermis layer.
