<u>Answer</u>: Natural selection.

<u>Explanation</u>:

  • The concept of <em>natural selection</em> was given by <em>Charles Darwin.</em>
  • According to this concept, in a given environment the organisms that possess <em>better adaptations</em> have<em> higher chances of survival</em> and, leave behind a <em>greater number of progenies</em>.
  • When malaria outbreak occurs, the allele frequencies change and only the organisms that possess the alleles which help them to <em>survive</em> this outbreak due to resistance against malarial infection will be selected by nature and<em> hence, this is an example of natural selection.</em>

The haversian canal and volkmanns canals both house blood vessels. The fact that she is bleeding so profusely means she has a hemorrhage and a hemorrhage is the loss of blood through the blood vessels through a ruptured wall. This sign is related because one of these canals was ruptured when her bone was fractured and forced out of the skin.

How does the human body prevent internal energy levels from becoming too low?
Lubov Fominskaja [6]

Answer:

c

Explanation:

The correct answer would be that the nervous system transmits feelings of hunger to the brain, which initiates eating.

<em>The human stomach and intestinal tracts consist of receptors that are able to sense the presence or absence of nutrients and send messages to the brain accordingly. If there are adequate nutrients in the stomach and the intestinal tracts, the receptors send a message to the brain and the hormone that makes humans feel fullness in their stomach is released into the blood. Once the available nutrient is low, the receptors send a message to the brain which in turn releases hormones into the blood that makes humans feel the sensation of hunger. </em>

The correct option is c.

Option (B) Transgenics is the correct answer.

Transgenics involves one or more DNA sequences being artificially introduced into an organism that wouldn't usually have them.

<h3>What is Transgenics?</h3>
  • The term "transgenic" refers to organisms with modified genomes.
  • For scientific investigation, most transgenic organisms are produced in laboratories. A particular gene of interest is disabled in transgenic mice called "knock-out" mice.
  • Researchers can learn more about the normal operation of the gene by researching its consequences.
  • It is possible to alter the genomes of living things with contemporary genetic technology. The term "genetic engineering" also applies to this method.
  • Additionally, commercial uses for transgenic organisms have been created.
  • Food crops like soy and peas that have undergone genetic modification to become resistant to pesticides and herbicides are probably the most well-known examples.

Hence, Transgenics entails the artificial introduction of one or more DNA sequences into an organism that wouldn't typically contain them.
