Why does our heart need two parts that are completely separate from one another?

Biology
1 answer:
SVETLANKA909090 [29]2 years ago
7 0

Answer:

the heart is separated into two sides so that it can carry out its function well. The right heart contains deoxygenated blood and the left heart with oxygenated blood. the two sides are separated from each other so that the blood from the two sides don't get mixed. this leads to effective oxygenation of the deoxygenated blood in the right heart through pulmonary circulation and effective oxygenation of the tissues in the different parts of the body by the oxygenated blood of the left heart through systemic circulation.

Question 8 (1 point)
Arlecino [84]

The term which best describes species C relative to species A is Sister

species. This is as a result of them sharing largest number of derived traits.

<h3>What is Ingroup?</h3>

Ingroup is defined as the group in which organism belongs to. We were

told that A and C are ingroup species.

Species A sharing the largest number of derived traits with species C

means that they have similar traits and a common parent which is a

characteristic of sister species.

Studentka2010 [4]

Answer:

Becomes completely enclosed by the region of the cell membrane into which the spikes and matrix protein are embedded

Explanation:

The viral capsid is a <em>protein shell that sorrounds a virus</em>, it serves as a criterion for the classification of viruses and <em>it encloses the genetic material of the virus and it has glycoproteins (spikes and matrix) embedded in it.</em>

Why does the rate of heart beat increases during exercise?
kherson [118]

During exercises, our muscles needed energy for contractions. The heart pumps more rapidly and more powerfully during this time for a few reasons.


First, more oxygen and nutrients like glucose can be transported to the heart. Muscle cells uses oxygen and glucose for aerobic respiration to generate energy.


Secondly, more carbon dioxide and waste can be transported away from the muscles. Waste products from aerobic respiration includes carbon dioxide or water etc. The faster the heart pumps, the faster the blood gets transported so more waste can be carried away.


Thirdly, lactic acid can be carried away too. When oxygen supply is not enough, the cells undergo anaerobic respiration to generate energy. This type of respiration does not require oxygen, but a waste product called lactic acid is produced. Lactic acid must be carried away from cells because they're harmful. Therefore, the faster the heart pumps, the more lactic acid gets carried away.


Last but not least, heat can be carried away too. Part of the energy generated is turned into heat. Therefore, in order to help us cool down, blood travels fast to carry heat away from the heat generating muscle cells.

What might two controlled variables (constants) Lisa would use for this experiment? ​
zhuklara [117]

There is no context so I will just explain what a constant is:

In an experiment following the scientific method, a constant is a variable that cannot be changed or is purposely not changed during the experiment.

An example would be:

If a researcher wanted to study the effects of temperature on the growth and development of garden snakes, the experimental variable for the experiment would be temperature. All other variables would need to remain consistent to avoid invalid data. The size of the cage, amount of light, food and many other variables would need to remain constant to ensure accurate results and a valid study. Those variables are constants. Some variables are not under a scientist's control, but are still considered to be constants. These constants are called universal constants and include gravity, the speed of light and electronic charge. Universal constants do affect experiments but will be constant through an experiment without being controlled by the scientist.
