Answer: The correct answer is- A. Chromosome numbers vary widely.
Chromosome can be described as thread like structure that is composed of DNA ( deoxyribonucleic acid) and possesses genes ( segment of DNA coding for a particular protein) on it.
Eukaryotic cells ( such as plant cell, animal cell) have variable number of chromosomes.
For instance, human beings have 23 pairs of chromosomes whereas it is different in plants depending on the species.
Thus, A) is the right answer.
These molecules involve an intermediate electron acceptor for oxidations that occur during glycolysis and Krebs reactions. It is part of cellular respiration.
<h3>What is cellular respiration?</h3>
Cellular respiration refers to a series of chemical reactions by which foods can be aerobically converted into energy (ATP) by using oxygen.
Cellular respiration can be divided into Glicolisys, the Krebs cycle and oxidative phosphorylation.
Cellular respiration involves oxide reduction reactions that involve the transfer of electrons (e-) between two or more substances.
