Q1. The answer is 53 chromosomes
Zebra has 44 diploid chromosomes (2n = 44). Zebra's gametes are haploid, so they will have 22 chromosomes (n = 22).
Donkey has 62 diploid chromosomes (2n = 62). Zebra's gametes are haploid, so they will have 31 chromosomes (n = 31).
After fusion of zebra's gamete (n = 22) and donkey's gamete (n = 31), the zonkey's zygote will have 22 + 31 = 53 chromosomes
Q2 and Q3. In the meiosis, the number of chromosomes is reduced by half. Since zonkey has 53 chromosomes, after meiosis it should have 53/2 chromosomes, which is not the whole number. This is the reason why they cannot produce normal gametes that will result, after the fusion, in the production of normal diploid zygote
C. Statement 1 is about an everyday life theory, and statement 2 is about a scientific theory.
Explanation - Statement 1: Children knocked over the trash can while cycling is an example of everyday life theory whereas Statement 2: Plant cells generate from sunlight and chlorophyll is an example of scientific theory.
In everyday life, if Children are not taught or explained, then they tend to throw the garbage or trash here and there thereby littering the street. Applying the scientific theory, plant cells uses sunlight, water, carbon dioxide and chlorophyll to perform photosynthesis.

Answer:
Difference Between Catabolism and Anabolism. Both anabolism and catabolism are metabolic processes, but the two are contrastingly different from each other. • Catabolism produces energy but anabolism uses energy. • In the catabolic pathways, the large molecules are broken down into small monomers whereas, in anabolism, small molecules are connected with each other, to form large molecules
Answer:
The number of bonds for a neutral atom is equal to the number of electrons in the full valence shell (2 or 8 electrons) minus the number of valence electrons. This method works because each covalent bond that an atom forms adds another electron to an atoms valence shell without changing its charge.
