Answer:
47
Explanation:
We all know that gametes like egg cell and sperm have haploid set of chromosomes but here as per this question she has produced 2 copies of chromosome 21. For the sake of maintaining haploidy, she was supposed to have only a single copy of chromosome 21 as a result of which her egg cell was supposed to have 23 chromosomes not 24.
But, this is a case of non dis-junction. Also, in a normal sperm there are no such copies of any chromosome i.e. there is a haploid set of chromosomes. It means that sperm must be having only 23 chromosomes. So we can easily infer that when the egg cell and sperm will fuse, the zygote will have 47 chromosomes (24 from egg cell and 23 from sperm).
I believe it is earth and Mars, if I’m wrong I’m very sorry
Answer:
The correct option is C. The cell followed Kreb's pathway.
Explanation:
Krebs cycle can be described as a metabolic pathway for the release of energy during the process of aerobic respiration. The Kreb's cycle constitutes a series of oxidation reactions through which pyruvate is converted into carbon dioxide. About 15 moles of ATP is released as a result of Kreb's cycle. The reactions of the Kreb's cycle take place mostly in the mitochondria. The Kreb's cycle is commonly named as the Citric Acid Cycle.
