Answer: Staphylococcus aureus is a gram positive bacteria which is round shaped bacterium that is usually found in the body. They are located in the respiratory track of the body.
Saccharomyces cerevisiae is a yeast species which is used in the brewing, wine making and baking long time ago.
When both of the species were observed under microscope then Saccharomyces cerevisiae will be larger than Staphylococcus aureus.
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.
