Answer:

Explanation:

Distilled water has no contaminants and minerals thus the solute concentration inside the RBC is more than water. Water moves towards high solute concentration, therefore, water will go inside the RBC and burst it. This is why no RBC will be seen. You could see remanants of burst open and defective RBC but healthly RBC wont be there.

Digestive enzymes help to break down food in its simplest form. Pepsin is a digestive enzyme which leads to the degradation of proteins in the stomach. It is produced as pepsinogen and converted to active pepsin in the stomach by the removal of several amino acids.

Pepsin is a digestive enzyme which is present mainly in the gastric juice in stomach and helps to breakdown protein into peptides.

This pepsin is present in the stomach in the form of inactive pepsinogen. This pepsinogen gets active in the stomach by the action of hydrochloric acid.

Pepsinogen gets active and forms pepsin.

Thus, it can be concluded that the digestive enzyme pepsin degrades protein in stomach and is synthesized as pepsinogen and gets converted into active pepsin in stomach by removal of several amino acids.

Cellular respiration and photosynthesis are similar in that both require energy-carrier molecules. The correct option is b.

The energy transport molecule found in cells in the highest concentration is adenosine 5'-triphosphate, or ATP.

Three phosphate groups, an adenine nitrogen base, and a ribose sugar make up this molecule. The compound adenine plus ribose sugar is referred known as adenosine.

During cellular respiration, glucose is produced using NADH and ATP. Both an enzyme and a channel protein, ATP synthase serves two functions.

ATP molecules include the carbon atoms from glucose after the conclusion of cellular respiration.

During the process of photosynthesis, two molecules that carry energy are actually present. NADPH and ATP are the two molecules that carry energy.

Thus, the correct option is B.

Projectile motion is the motion of an object in two dimensions. This means that if an object moves in both the horizontal and vertical directions at the same time, it is said to be exhibiting a projectile motion. In simple words, if an object tends to follow a curved or parabolic path of motion, projectile motion is said to be existing.

The characteristic of bacteria that makes them efficient transgenic organisms to produce insulin or other medicines is they readily accept new genetic material.

Transgenic organisms may be defined as an organism whose genome has been modified by the insertion of one or more foreign (non-self) DNA sequences from another species via artificial means.

A Plasmid is a circular DNA that assists in the insertion of foreign DNA sequences into the bacterial cell.

Therefore, the characteristic of bacteria that makes them efficient transgenic organisms to produce insulin or other medicines is they readily accept new genetic material.

Explanation:

The percentage of offspring from a cross between an animal that is heterozygous for the dominant trait of having horns and an animal that is homozygous recessive and has no horns is 50%.

A punnet square is a graphical representation used to determine the probability of an offspring expressing a particular genotype.

According to this question, an animal that is heterozygous for the dominant trait of having horns (Hh) is crossed with an animal that is homozygous recessive and has no horns (hh).

The offsprings of this cross is as follows:

Therefore, the percentage of offspring from a cross between an animal that is heterozygous for the dominant trait of having horns and an animal that is homozygous recessive and has no horns is 50%.

Yes, this is plenty of time for the humans in Mars to revolve differently. Due to Mars having different features (plants, air quality, etc) the people on Mars may develop differently to aid them in living on a different planet. They may develop a different variation of lungs to help them breathe better. Another possibility is a development that allows them to store water linger due to possible lack of water. In this span of time, humans on Mars may have begun developing these difference tools. As a result, in many years after the humans on Mars could almost be completely unrecognizable to the humans on Earth.

Acc6ording to the question:

The respiratory membrane includes millions of alveoli with a surface area, the large respiratory surface area, combined with other factors, makes for efficient gas exchange to meet our metabolic needs.

Respiratory membrane allows gases to be exchanged between the pulmonary capillaries, or blood vessels, and the respiratory units of the lungs, which consist of bronchioles, alveolar ducts, atria and alveoli.

Since respiratory membrane is very thin,it consists of only two cells, one is the alveolar epithelial cell and the other is pulmonary capillary cell.Gas exchange occurs in the lungs between the air and our blood.
