Answer:
parasitism
mutualism
commensalism
Explanation:
Commensalism is defined as a relationship between two living organism in which one organism get benefits and the other organism neither benefit nor harm.
Herbivory is defined as the relationship between organisms and plants in which organisms consume plant material.
Mutualism is defined as the relationship between two living organism in which both organisms benefit each other.
Parasitism is defined as the relationship between two living organism in which one organism get benefits and the other organisms get harmed.
So, a flea and dog are an example of parasitism, certain bacteria live in the digestive tract of humans is an example of mutualism, and relationship between cattle egrets and an elephant is an example of commensalism.
Hence, the correct answer is:
parasitism
mutualism
commensalism
Answer:
C. Diabetics will have ample supplies of insulin that are produced by bacteria.
Explanation:
The technology of recombinant DNA has allowed scientists to introduce the human insulin gene into E.coli bacteria. E. coli are thus turned into "biological factories" that produce large quantities of human insulin, which can be easily purified and used as medicine for diabetics.
There are many more examples of DNA recombinant technology in human medicine, such as the production of recombinant human growth hormone (hGH) also in E. coli that is injected in individuals who don't produce enough hGH naturally, or even the production of vaccines by inserting antigen-coding DNA into a cell, purifying it and later injecting it into individuals to stimulate immunization.
These changes occur due to increased heart rate (measured by taking pulse) without maintaining his normal blood pressure is suggestive of reduced stroke volume. Both drop in blood volume and a weakened heart could cause this, however, the chest pains suggest heart damage. Failure of compensating mechanisms to maintain blood pressure suggest a serious decline in cardiac output.
