Answer:
a. autotriploid of species A: 63 chromosomes
b. autotetraploid of species B: 96 chromosomes
c. allotriploid from species A and B: 1) 66 chromosomes and 2) 69 chromosomes
Explanation:
<u>For a.</u>
this species will have 3 haploid sets of chromosomes ('tri' means 3)
one haploid set = 21
21 × 3 = 63 chromosomes
<u>For b.</u>
this species will have 4 haploid sets of chromosomes ('tetra' means 4)
one haploid set = 24
24 × 4 = 96 chromosomes
<u>For c.</u>
there are two ways to do this:
1) two sets of chromosomes from species A and one from species B
42 + 24 = 66 chromosomes
2) one set of chromosomes from species A and two from species B
21 + 48 = 69 chromosomes
Hope that answers the question, have a great day!
I am pretty sure the answer is increase and increase. Because enzymes are affected by changes in pH. The most favorable pH value - the point where the enzyme is most active - is known as the optimum pH. Extremely high or low pH values generally result in complete loss of activity for most enzymes.

Answer:
The correct answer would be b. because water provides electrons.
During the light reaction of the photosynthesis, the water is photolysed into high energy electrons, hydrogen ions, and oxygen.
The overall reaction can be written as:
2 H₂O + sunlight → 4 H⁺ + 4 e⁻ + O₂
It takes in water-splitting complex associated with photo-system II rooted in the thylakoid membrane of chloroplast.
The oxygen is released as the byproduct of photosynthesis.
The hydrogen ions help in the formation chemiosmotic potential across the thyllakoid membrane which help in the formation of ATP (adenosine triphosphate).
The electrons are used to replace the electrons lost from chlorophyll a of reaction centre associated with photo-system II. The electrons are lost due to the photo-excitation of chlorophyll a.
The electrons lost from chlorophyll a help in the production of ATP and are used to reduce NADP⁺ into NADPH.
The ATP and NADPH are used in light-independent reaction of the photosynthesis to produce glucose or food.
