Cellular respiration is the process responsible for converting chemical energy, and the reactants/products involved in cellular respiration are oxygen, glucose (sugar), carbon dioxide, and water. While the exact steps involved in cellular respiration may vary from species to species, all living organisms perform some type of cellular respiration. Without cellular respiration, living organisms wouldn’t be able to produce the chemical energy they need

Answer:
45 chromosomes (2n1 + n2)
Explanation:
The allotetraploid 2n1+2n2=60 has 60 chromosomes total, two sets of them of type 1 and two sets of chromosomes from the other type (2).
If the suspected type 1 parent is diploid with 30 chromosomes, then the allotetraploid has 30 type 1 chromosomes and 30 type 2 chromosomes.
<u>During meiosis, the germ cells reduce the total chromosome number by half.</u>
- The gametes produced by the allotetraploid will have 15 type 1 chromosomes and 15 type 2 chromosomes.
- The gametes produced by the suspected parent will have 15 type 1 chromosomes.
When these gametes combine during the backcross, the F1 zygote will have a diploid number of 30 type 1 chromosomes (15 coming from the allotetraploid and 15 coming from the suspected parent) and 15 type 2 chromosomes (which will be haploid because they all came from the allotetraploid).
Insufficient nutrient, lack of water, no sunlight, climate change, pollution
