Fixator (--) helps hold a bone in place
C but it's still not exactly correct, they would just be definite carriers of the colour blind trait but only the girls are able to obtain the gene
Answer: The scientist will perform another investigation in order to find out the role of certain genes in disease resistance.
Explanation-
As per the information given in the question, a mice having mutation in ear depicts same pattern of resistance when compared to another mice having normal ears. This indicates that the genes responsible for resistance are not related to genes that result in ear formation.
Therefore, to find out the effect of diet on disease resistance in rats, the scientist will perform another investigation in order to find out the role of certain genes in disease resistance.
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.
