or you can say:
Point mutations are a large category of mutations that describe a change in single nucleotide of DNA, such that that nucleotide is switched for another nucleotide, or that nucleotide is deleted, or a single nucleotide is inserted into the DNA that causes that DNA to be different from the normal or wild type gene ...
dude, you asked brainly the whole worksheet?? Do it yourself sreerag!!
Answer:
A pair of homologous chromosomes fails to separate during anaphase I of meiosis.
Correct answer: D) Loss of insulation around vital organs
Fat is a nutrient should be to be taken in the diet but not in excess amount, it provides energy and help the body to absorb the vitamins.
It consists of a hydrocarbon chain and served to provide the structural and functional unit of the cell. The cell membrane is made up of a phospholipid bilayer, which consists of phosphate and glycerol.
The main function played by the fat inside the body include the transformation of energy and providing heat insulation to the body.
The adipose tissue of the body act as an insulator. As it contains fat molecule, and fat is a poor conductor of the heat, it traps the heat across the vital organ of the body such as heart, eyes etc. Due to the bad conductivity, fat molecule act as an insulator. It also acts as a cushion for most of the important organ of the body and protects them from damage and mechanical injury.
