Answer:

The answer is B. Many small changes can create a whole new species.

Explanation:

Natural selection is a strong source of speciation in living beings.

After several generations, it is possible to observe distinctive features at the level of a population. A clear example of this can be observed in humans, where some physical traits are characteristic of different regions.

If sufficient time passes, it is possible that the differences of one population are sufficient to differentiate from another similar population, creating reproductive isolation and giving rise to a new species.

The blood in an artery flows faster and at higher pressure. Explain why.

Elenna [48]

Answer:

The blood in an artery flows faster and at higher pressure. Its because pressure is a measure of the force that the blood exerts against the vessel walls as it moves the blood through the vessels. Like all fluids, blood flows from a high pressure area to a region with lower pressure. Blood flows in the same direction as the decreasing pressure gradient: arteries to capillaries to veins.Moreover the arteries have thicker smooth muscle and connective tissue than the veins to accommodate the higher pressure and speed of freshly pumped blood. The veins are thinner walled as the pressure and rate of flow are much lower.

Describe how microbes of the normal flora in the human body can become opportunistic pathogens. Give one (1) example of a normal

Brilliant_brown [7]

Answer:

Opportunistic pathogens may be defined as the pathogens that are normally not able to cause infection but when get an advantage they multiply in number and can cause disease.

The normal flora of the skin can become opportunistic pathogens as they get the advantage by change in the skin environment. The damage to the sin and their excess multiplication and in case of weak immune system the normal skin flora become the opportunistic pathogen.
