Answer:
a. Zero percent
b. Fifty percent
Explanation:
As it has been mentioned in the question that both man and woman are normally pigmented and each one have an albino parent thus both will be heterozygous and their allelic makeup will be as follows -
Man - Aa
Woman - Aa
After a cross between Aa × Aa we get the following result-
One AA, Two Aa and One aa
It is clear that only the aa type of offsprings will be albino.
Out of 4 there is probability of only one to be albino so out of two there will be 50% probability of being albino.
The probability of both sons to be albino will be zero percent.
Answer:
plant leaves contain openings called stomata, which allow the diffusion of gas exchange
Answer: a. Stomata open at Night
Explanation:
As a tactic to minimize photorespiration in warm regions, many water-storing plants such as cacti and pineapples modified its method of carbon fixation. This process is called Crassulacean Acid Metabolism (CAM), following the plant family Crassulaceae, in which it was first identified. In these plants, the stomata (singular, stoma), specialized openings in the leaves of all plants through which CO2 enters and water vapor is lost, open during the night and close during the day. This model of stomatal opening and closing is the opposite of that in most plants.
