Answer:

Fasting can definitely raise blood glucose. This is due to the effect of insulin falling and the rising counter-regulatory hormones including increased sympathetic tone, noradrenaline, cortisol and growth hormone, in addition to glucagon. These all have the effect of pushing glucose from liver storage into the blood. This is normal. If you are not eating, you want to use some stored glucose. The question is this – if you are not eating, and your blood glucose went up, where did that glucose come from? It can only have come from your own body (liver). So, it’s a natural phenomenon, and the fasting now allows your body to use some of the glucose for energy.

Answer:

Obligate mutualism.

Explanation:

Obligate mutualism: It is defined as each organisms are obligated to each other, they rely on one another, means one species cannot survive without the other species. It may involve the interchange of resources, for example food, shelter, and nutrients or may interchange services like transportation, and protection.

Termites are mutualistic related to protozoa which lives inside the insects gut. Termite gets benefits from the bacterial symbiont ability which is present in the protozoa to digest the cellulose. The termites do not have this ability to do this, without the help of protozoa. They are not able to use their energy from the food which is wood, cellulose comes from wood it chews.

So, termites are mutualistic related to protozoans and showing obligate mutualism.
