Answer:

Cells have a double stranded DNA molecule and many strands of single stranded RNA as the copies. Viruses, however, can have double stranded DNA, single stranded DNA, double stranded RNA, or single stranded RNA. They convert RNA to DNA and then back to RNA to make proteins, which does not happen inside cells.

Answer:

The overall (unbalanced) chemical equation for cellular respiration is: C6H12O6+O2→CO2+H2O+energy.

Answer:

By experimenting on the hypothesis using step by step scientific methods.

Gathering the data, analyzing the data, drawing conclusions and if the hypothesis isn't conclusive a new hypothesis will be formulated to check out the problem.

Mitochondria are cellular organelles that are in charge of oxidative phosphorylation, which is the critical process of turning nutrients into adenosine triphosphate (ATP) molecules that power normal cell operations. At least hundreds of mitochondria are found in each neuron. Because nerve cells are postmitotic, any mitochondrial damage received will accumulate over time and produce malfunction. Cells die as a result of widespread mitochondrial damage because they can no longer create adequate energy.

During physical exercise, more oxygen is used up and more carbon dioxide is produced leading to faster and deeper breathing.

Physical exercise is a state in which the muscles are flexed much vigorously leading to a faster heartbeat owing to a quicker rate of pumping of the blood by the heart.

There are two main reasons why a person engaging in physical exercise tends to breathe faster and more deeply;

Do you think one gene controls human hair color?

No, this is false. Not only one gene is responsible for the colour of your hair, at least 2 gene pairs control human hair colour. Therefore, this is wrong since each parent contributes multiple hair-colour genes .

Hope this helped you, have a good day bro cya)

Answer:

There are many different phenotypes for hair color among humans. Therefore, multiple genes control hair color.

Answer:

endoneurium

Explanation:

The endoneurium is a layer of connective tissue composed of endoneurial cells that surround and protect the myelin sheath of each myelinated nerve fiber.

nerve fibers are insulated from one another by endoneurium.

A nerve fiber is a long axon from a nerve cell (neuron muscle). The body of the nerve cell is anatomically located either inside the ganglia of the peripheral nervous system or within the central nervous system.

The ganglionic neurons' axons that travel from the retina's vitreal surface to the optic disc make up the nerve fiber layer. These axons are not myelinated until they reach the optic disc and break through the sclera. The optic disc's white color is a result of oligodendrocytes' myelination of them at this point. They help in the communication of two nerve fibers.

Thus, nerve fibers are insulated from one another by endoneurium.

Short paragraph:

Homeostatis is the process by which the body maintains a stable internal environment. The hypothalamus is a part of the brain that regulates many key body processes. It works to restore the system to its normal state when an internal change in one of these systems occurs.

Long paragraph:

The hypothalamus is a part of the brain that regulates many key body processes including internal body temperature, hunger, thirst, blood pressure, and daily (circadian) rhythms. When the brain receives signals from the body about an internal change in one of its systems, it works to restore the system to its normal state. For example, the normal internal temperature for the human body is approximately 98.6 degrees Fahrenheit. If the body temperature rises because of exercise, the body will try and cool itself off. This happens through coordination between the hypothalamus and the various body systems that are affected.

Answer:

Cardiac muscle differs from skeletal muscle in that it exhibits rhythmic contractions and is not under voluntary control.

Answer:By their activity in the soil, earthworms offer many benefits: increased nutrient availability, better drainage, and a more stable soil structure, all of which help improve farm productivity. Worms feed on plant debris (dead roots, leaves, grasses, manure) and soil. ... Nitrogen in the casts is readily available to plants.

Explanation:

Earthworms have the ability to eat and mix large amount of soil and organic matter and deposit it in the form of casts. They also enhance incorporation and decomposition of organic matter, increase soil aggregate stability, improve porosity and water infiltration, and increase microbial activity.

Answer:

They have more genes than unicellular organisms.

Explanation:

They show properties that can only result from the interaction of many cells.

Answer:

Anaerobic respiration begins the same way as aerobic respiration and fermentation.

Explanation:

However, instead of ending with glycolysis, as fermentation does, anaerobic respiration creates pyruvate and then continues on the same path as aerobic respiration.

As both altitude and atmospheric pressure increase, the partial pressure of O2 will decrease.

Though I could not locate the options online to provide an exact answer, I can offer a general overview of the question at hand.

The interactions between altitude and the partial pressure of oxygen are inversely proportional. This means that as one increases, the other will decrease. The proportion of oxygen is 21% of the air content at all altitudes. However, as the altitude increases, the atmosphere becomes thinner, meaning that the partial pressure of O2 will decrease given that 21% of a thinner atmosphere results in less oxygen.

On the other hand, the relationship between atmospheric pressure and oxygen is that they are directly proportional. This means that as one decreases, the other does as well. In this case, since atmospheric pressure is the sum of the partial pressures of all gases, we can conclude that as it decreases, so to will the partial pressure of oxygen.
