Dramatic temperature changes can induce membrane remodeling involving changing fatty acid structure in membrane phospholipids. T
dezoksy [38]

Answer:

c. The ratio of long to short fatty acid tails in the membrane phospholipids increases

e. There is an increase in the saturation state of the fatty acid tails of membrane phospholipids

Explanation:

In biological lipid membranes, the homeoviscosity refers to the process by which the membrane 'adapts' its lipid composition to maintain a proper fluidity. It is well known that the membrane's fluidity increases with increasing temperatures. In this regard, it is important to have into account two points. First, the length of the fatty acid tail alters the membrane's fluidity: shorter fatty acid tails increase fluidity, while longer fatty acid tails decrease it (because shorter tails establish fewer molecular interactions between fatty acids tails). Second, the degree of saturation (i.e., the number of bonds between the carbon atoms) of fatty acids tails also affects homeoviscosity. A higher saturated fatty acid content decreases the membrane's fluidity because saturated tails are arranged in order to maximize molecular interactions between fatty acids tails.

As an experiment, you infect bacteria with an unknown virus to see how the bacteriophage affects the bacteria. After a few days,
GaryK [48]

Answer:

<h2>The virus is a bacteriophage that is reproducing the lysogenic cycle.</h2>

Explanation:

When bacteriophage infect the bacteria, it can enter one of two cycles i) lytic or ii) lysogenic cycle.

In lysogenic cycle, virus injects its genome into the bacterial chromosome, known as prophage and it replicates with bacrerial DNA. When conditions change, this prophage can remove itself from the bacterial DNA , and lysogenic cycle can change into lytic cycle.
