Answer:
1. 128
2. 16,384
Explanation:
Imagine there were two pairs of chromosomes:
A paired with B
C paired with D
A gamete could have the following combinations:
A + C
A + D
B + C
B + D
Therefore, with two pairs of chromosomes, there are 4 (2²) possibilities
With seven pairs of chromosomes, there are (2⁷) possibilities. 2⁷ = 128
For a zygote produced by two barley parents, there are two gametes fused. So we must multiply the number of combinations for each gamete. Therefore, number of possible genetic combinations is 128 x 128 = 16,384
Could you attach a picture of the painting so i can better answer this?
Respiration is the reverse of Photosynthesis.
B- Reproducing more often. If the environment is not right for them then reproduction doesn’t help them adapt. They respond by changing behavior, moving to another area, and even modifying their physical bodies (diets included).
