Cells that protect the body by engulfing foreign cells or producing antibodies are D. White blood cells.
Answer:1)Yeast cells that produce more unsaturated fatty acids than saturated fatty acids in response to cold have greater cold tolerance
2)Cell membranes in reindeer legs (near the hooves) are kept flexible because they have a large number of saturated fatty acids.
3.)Cell membranes in cold tolerant winter wheat plants have a higher ratio of unsaturated fatty acids to saturated fatty acids than do cold intolerant wheat varieties.
Explanation.
Basically the longer the chains of fatty acids the higher the degree of energy produced as heat energy, and therefore the higher the insulation.
Unsaturated fats clogged together and the aggregate carbons and hydrogens ensured insulation.

PROTO-ONCOGENES are corresponding normal cellular genes to an oncogene that is responsible for normal cell growth and division.
An oncogene refers to a gene that is capable of causing cancer due to damage to the DNA molecule either by virus or other DNA damaging agents. A proto oncogene is the normal version of the gene while an oncogene is the abnormal version of the concerned gene.
