Answer:
50%
Explanation:
Let the allele for red-green color blindness be represented by c.
Normal vision woman whose father is color-blind will be 
Color-blind male will be 
x
Progeny: 
(See the attached image)
<em>Out of the 2 male progeny, 1 is affected for color-blindness while the other is not affected. This gives a 50% probability that a son of the couple will be color-blind.</em>
It changes because the age increases
Answer:
Biodiversity is important because it boosts an ecosystems productivity where each species, no matter how small, all have an important role to play.
Explanation:
An example of Hector's somatic sensory system is in control is well demonstrated when after a long run, his body is sweating.
Answer: Option A
<u>Explanation:</u>
The somatic sensory system of the body refers to the living sensory system which is the system of sending response to the body in response to the stimuli felt or sensed. The motor neurons and sensory neuron comprises the system and when ever there is a change in the body outer or inner core which forms an stimuli, signals the somatic sensory system, and a response is signalled back.
So, when the Hector is running for a long time, the body heats up due to constant retraction and expansion of the muscle due to friction, the glucose molecule as energy is also exhausted, so counter the change, sensory system, cools the body from the heat produced, the cooling of the body is achieved by sweating. Therefore, Option A is the correct answer.
Answer:
Approximately 25 arteries would branch off
Explanation:
Aorta has a diameter of 2 cm, so area is pi x 1^2 = 3.142
In case of the artery, pi x 0.2^2 = 0.126
So dividing total area of aorta by total area of one artery, we get 3.142/0.126 = 25.021
Hence, about 25 arteries will be needed to carry the amount of blood that flows in the aorta vessel.
