Abiotic factors (such as weather and environment) will determine which organism will be superior compared to another.
For example, Lion will be placed as the highest in the food chain if they're in Savanna environment. But, if we place that lion in the middle of the ocean, the lion will not has the superiority that it has on land.</span><span />
Plant Characteristics. Plants are autotrophs; they produce their own food. They do so via photosynthesis, which is the process of making nutrients such as sugars from light energy and carbon dioxide.

The significance of the spore formation during the reproductive cycle of the bacterium is that, it provide a defensive strategy against hostile and unfavorable conditions. The spore formation allows the bacterium to reproduce and spread even when the conditions are not favorable. The spore formation also make it possible for the bacterium to remain dormant over a long period of time during unfavorable conditions, waiting for the right conditions to become active again.
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!
