Consider a series of metabolic events during fasting. Within a few days after a fast begins, nitrogen excretion accelerates to a
timurjin [86]

Answer:

A series of events occur, in prolonged fasting; the body undergoes changes and adaptations of its metabolism to continue to meet energy needs and maintain vital functions, despite not receiving food

These changes are divided into three phases according to the elapsed days of fasting and according to the metabolic processes involved.

First phase: main consumption of reserve carbohydrates.

Second phase: main consumption of fats.

Third phase: serious consumption of proteins.

Explanation:

If the fast is prolonged in time, the metabolic processes change in their qualitative and quantitative characteristics, so that the energy products consumed (glucose, free fatty acids and ketone bodies) are modified, their oxidation decreases globally and after the initial depletion of hepatic and muscular glycogen and protein catabolism, the main source of glucose is the liver through gluconeogenesis. The substrates initially come from protein catabolism and lipolysis, but later protein destruction slows down, maximizing lipolysis.

Between the first phase and the second phase of the fast some muscle proteins are lost but not excessively, even with fasts of two or three weeks.

After about 2 weeks of fasting, up to two-thirds of the energy the brain needs is obtained from ketone bodies. These ketone bodies are the breakdown products of fats and are responsible for the typical ketone breath reminiscent of the smell of acid apples; urine also smells like ketone.

In this phase, damage begins to occur in some important organs such as the liver and kidneys. Starting the first week of fasting, acidosis affects the heart's function of the circulation and the brain.

In the third phase of the prolonged fast it happens from 3 weeks, that is, about twenty days without food, although it varies according to the constitution of each person. A peak of muscle protein consumption occurs and a great loss of weight begins to be perceived with great weakness. Edema occurs and albumin concentration in the blood is altered, as a sign of the self-digestion of muscle proteins.

From approximately 30 days of fasting, the state of malnutrition severely affects all body systems. After forty or fifty days the deterioration is noticeable due to physical wear, the person loses his mobility and suffers from unconsciousness. Finally, starvation death can occur from cardiorespiratory arrest or from lack of blood supply to the brain.

Why would a Nonsense mutation be less damaging if it occurred at the end of the gene rather than the
kari74 [83]
Nonsense mutations make stop codons. If the mutation is towards the beginning of a gene, then the protein that gets created will be cut short and not function properly. But if it was towards the end, there is still a chance that the protein will still be able to work.

When recombinant DNA is inserted into the genome of a host organism, what's created? A. A genetic marker B. A restriction enzyme
PIT_PIT [208]

The answer is C.

Transgenic means that one or more DNA sequences from another species has been introduced by artificial means. For example, animals usually are made transgenic by having a small sequence of DNA injected into a fertilized egg or developing  embryo. Transgenic plants can be made by introducing foreign DNA into a variety of different tissues.

Most transgenic organisms are generated in the laboratory for research purposes. Others have been developed for commercial purposes  such as golden rice that has been modified to produce beta-carotene, the precursor to vitamin A.
