Question 4

The regulation of blood pressure is an example of local homeostatic controls .

Accepted Answer

The regulation of blood pressure is not an example of local homeostatic controls, but rather a systemic control mechanism involving the cardiovascular and renal systems. Local homeostatic controls typically refer to processes that occur within a specific tissue or organ, such as regulation of blood flow or oxygen supply.

Question 7

Elastin, the most elastic material known, is found only in insects and some crustaceans. ​

Accepted Answer

Elastin is found in many animals, including mammals, not just insects and crustaceans.

Question 8

An organized group of specialized cells is called a(n)organ . ​

Accepted Answer

An organized group of specialized cells is called a tissue.

Question 9

How are the cells of a multicellular animal connected to the external environment? Briefly describe how nutrients and wastes are transferred from these cells to the external environment. ​

Accepted Answer

The answer of How are the cells of a multicellular...

Question 10

Tight junctions between muscle cells help muscle tissue function as a unit.

Accepted Answer

Tight junctions are characteristic of epithelial cells, where they help to create a barrier to prevent the passage of materials between cells. In muscle tissue, it is the gap junctions, not tight junctions, that allow muscle cells to function as a unit by facilitating the direct transfer of ions and small molecules between cells, enabling coordinated muscle contraction.

Question 11

Blood plasma is separated from cells by interstitial fluid . ​

Accepted Answer

The answer of Blood plasma is separated from cells by...

Question 13

Skeletal muscle is arranged in highly ordered parallel units, giving the tissue a banded appearance under a microscope.

Accepted Answer

Skeletal muscle is arranged in parallel units called myofibrils, which contain repeated units called sarcomeres. This arrangement gives the tissue a banded appearance, known as striations, when viewed under a microscope.

Question 16

The cell body of a neuron propagates electrical signals to the axon terminals. ​

Accepted Answer

The cell body of a neuron integrates signals and the axon propagates electrical signals to the axon terminals.

Question 17

The birth process in mammals is an example of positive feedback .

Accepted Answer

The birth process in mammals involves the positive feedback mechanism where the contractions of the uterus cause the release of the hormone oxytocin which, in turn, causes stronger contractions. This positive feedback loop continues until the baby is born.

Question 18

People who do not exhibit changes in blood pressure based on a circadian rhythm are more likely to have a heart attack.

Accepted Answer

Research has shown that individuals who have a blunted or absent circadian blood pressure rhythm are at higher risk for cardiovascular events, including heart attacks. This is because a blunted or absent rhythm can lead to sustained high blood pressure, which can damage the arteries and increase the risk of heart disease.

Question 19
