A bacterium is suddenly expelled from a warm human intestine into the cold world outside. Which of the following adjustments would the bacterium do to maintain the same level of membrane fluidity?a. Decrease the amount of glycolipids in the membrane.
b. Decrease the amount of cholesterol in the membrane.
c. Produce lipids with hydrocarbon tails that are longer and have fewer double bonds.
d. Produce lipids with hydrocarbon tails that are shorter and have more double bonds.

Option D

Explanation:

It reduces the tendency for hydrocarbons to interact with one another and the double bond produces kinks on the hydrocarbons chain which makes them difficult to pack together and this makes membrane remains fluid at lowered temperature

interphase

the period of cell growth when the cell synthesizes new molecules and organelles. the cell is not dividing and it constitutes the majority of the time spent in the cell cycle

prophase

changes occur in the nucleus and cytoplasm. the chromatin condenses to form structures (sister chromatids) visible with a light microscope and the mitotic spindle begins to form, but the nucleus is still in tact

prometaphase

the nuclear envelope fragments and the spindle microtubules attach to the kinetochores of the sister chromatids

metaphase

all the cell's duplicated chromosomes are lined up at an imaginary plane equidistant between the poles of the mitotic spindle

anaphase

begins when sister chromatids separate from each other and ending when a complete set of daughter chromosomes arrives at each of the two poles of the cell

telophase

the daughter nuclei form at the two poles of a cell

cytokinesis

the division of a cytoplasm to form two separate daughter cells. usually occurs during telophase during mitosis. this and mitosis make up to mitotic (m) phase of the cell cycle
