The process that requires energy for digested nutrients to pass through the small intestinal wall into the villi is called active transport

In the process of digestion, complex food molecules are broken down into macromolecules which are absorbed by the body. The absorption of nutrients such as glucose, vitamins, and amino acids takes place in the small intestine.

The small intestine contains tiny hair-like projections called the microvilli that are rich in blood vessels. These structures help in the absorption of nutrients.

As the concentration of these nutrients is higher in the bloodstream than in the intestine. The absorption of nutrients requires energy for the movement of nutrients from lower concentration to higher concentration. This energy-driven transportation is called active transport.

Which of the following are examples of positive feedback loops? (Choose all that apply)

aleksley [76]

The examples of positive feedback loops are as follows:

contractions during the process of giving birth
Blood clotting

<h3>WHAT IS POSITIVE FEEDBACK LOOP:</h3>

Positive feedback loop is that in which a change in a given direction causes additional change in that same direction.

The contractions during the process of giving birth is an example of positive feedback loop because the contractions further stretch the walls and continues until birthing occurs.

Also, the clotting of blood causes the stoppage of blood flow.

Therefore, the examples of positive feedback loops are as follows:

contractions during the process of giving birth
Blood clotting

Since the flowers are of blue or yellow color, it is essential for a bee to be able enough to perceive the blue and yellow color. Hence, the eyes of bee with time have evolved to perceive these two color so that they can pollinate flower.

Explain how a change in the environment can cause the disappearance of traits or possibly cause an extinction of a species.

aliya0001 [1]

Answer:

Changes in the environment may leave individuals less well adapted to compete successfully for resources such as food, water and mates. Sometimes an entire species may become unable to compete successfully and reproduce. These problems can lead to extinction.
