Answer:
Alloy is a mixture made up of iron &nickel.
Answer:
D
Explanation:
becoz it is an animal cell
Answer:
In the presence of arsenate glycolysis produces fewer ATP and NADH molecules per glucose molecule.
Explanation:
it is supposed to be 2 molecules of 3-phosphoglecerate with each producing 2 ATP making a total of 4 ATP gain but since it is just one and arsenate, only 2 ATP will be generated instead of four, thus ATP yield is reduced.
The correct option is A ie the process whereby non-sister chromatids exchange genetic material
- Between prophase I and metaphase I, a process known as crossing over occurs in which two homologous non-sister chromatids join up and exchange various pieces of genetic material to create two recombinant chromosome sister chromatids.
- When genetic material is switched between two chromosomes, this process is known as crossing over.
- It is in charge of causing genetic variation among members of a species.
- Only the reproductive cells known as gametes undergo this process.
- The steps involved in crossing over are as follows:
1) Synapsis.
2) Chromosome duplication
3) Crossing over.
4) Terminalizataion.
