What is not natural selection

Biology
1 answer:
TEA [102]3 years ago
3 0

Answer:

Evolution is not a random process. The genetic variation on which natural selection acts may occur randomly, but natural selection itself is not random at all. The survival and reproductive success of an individual is directly related to the ways its inherited traits function in the context of its local environment.

Explanation: Hope this helps!

Gene flow and genetic drift both affect allele frequencies in a population. A high level of gene flow into a population genetic
DaniilM [7]

A high level of gene flow into a population increases genetic diversity in a population. A high level of gene flow out of a population decreases genetic diversity in a population. Genetic drift is the change in allele frequencies due to "sampling error" factors. Typically, genetic drift has the biggest impact on small populations.

Gene flow (or gene migration) is a mechanism of evolution (change the allele frequencies) which transfers genetic variation among populations due to migration. High level of gene flow decreases the genetic differentiation between the two populations.

Genetic drift is a mechanism of evolution that acts by chance (“sampling error”) often when a population is reduced in size by a natural disaster (bottleneck effect) or when a small group leaves the main population and forms a colony (founder effect).

The ionic group coo- on succinate forms bonds with the succinate dehydrogenase
Dmitriy789 [7]

At neutral pH, the ionic group COO- on succinate makes bonds with the active site of succinate dehydrogenase. This bonding is required for succinate oxidation.

<h3>What is succinate oxidation?</h3>

In the Krebs cycle , succinate dehydrogenase catalyzes the oxidation of succinate to fumarate, with the resulting electrons being supplied to respiratory chain complex III to decrease oxygen and produce water.

SDH oxidizes succinate to fumarate during the citric acid cycle. SDH is structurally similar to fumarate reductase, an enzyme that catalyzes the opposite process during anaerobic respiration in bacteria.

A 35-year-old male complains of a "pressure" type headache to the back of his head and neck. He states that he woke up with the
tigry1 [53]

Answer:

Answer is D. Tension

Explanation:

Tension headache is a type of headache that can be described as feeling of dull or moderate pain in the head, which can be inform of a tightness around the head and the neck.Tension headache is also known as stress headache.

It has been discovered that, various activities like driving for a long period of time, staring to a computer for a long period and exposure to cold temperature, can cause tension headache.

The following activities can be developed to reduce or avoid tension headache.

* Drinking a lot of water.

* Regular exercise.

* Sleeping very well

* Limiting stress

* Eating foods like almond and walnut.

In this case, the complaint of a 'pressure' type headache to the back of the head and neck by the man, was a typical feeling ,synonymous to tension headache.
