Answer:
Option C, They allow random distribution of genetic material when a cell divides.
Explanation:
The chromatin are responsible for packaging of DNA molecule into smaller space with in a chromosome. It not only package it but also protect it from. Packaging allows for easier division of cells during mitosis and meiosis and hence prevent any kind of damage to the DNA.
Chromosomes make recombination and random segregation of genetic material to form new cells. Each new cell gets equal number of chromosomes
Hence, option C is correction
<span>A single stranded nucleic acid that plays a role in protein synthesis is known as the messenger RNA or mRNA (messenger Ribonucleic Acid). The other two types of nuclei acids are transfer RNA or tRNA and ribosomal rNA or rRNA. These nucleic acids are involved in cellular division in cells, during which transcription and translation occurs.</span>
Answer:
Water
Explanation:
Molecular oxygen is the terminal electron acceptor and serves to receive electrons from reduced NADH and FADH2 to reoxidize them. NADH and FADH2 are formed during glycolysis and Kreb's cycle. These reducing powers should be re-oxidized to enter in the first two steps of aerobic respiration again.
For the purpose, NADH, and FADH2 transfer their electrons to the molecular oxygen via electron transport chain. After accepting the electrons, molecular oxygen is oxidized into the water molecule. Therefore, radioactive oxygen isotope would appear in the form of a water molecule after completion of cellular respiration.
Answer:
D
Explanation:
Bacteria, air, animals, plants
Answer:
The purpose of the organs of the male reproductive system is to perform the following functions: To produce, maintain, and transport sperm (the male reproductive cells) and protective fluid (semen) To discharge sperm within the female reproductive tract during reproduction
