Jessica travels to a remote village in the Amazon jungle in order to work as a medical volunteer. While in this village, Jessica

discovers a new animal species that has a very selective diet. She observes that this specific species eats only fruit and plant products. Intrigued by this new animal species and its unique diet, Jessica decides to study the alimentary canal of this organism. One finding that is particularly interesting to Jessica, however, is the mucosal layer of the stomach. She notes that one cell is missing.
Which of the following cells would most likely be missing from the new species’ stomach mucosa?

a) Chief cell, because it releases pepsin, an enzyme necessary for the digestion of proteins.
b) Goblet cell, because this organism does not need to release mucus along the alimentary canal.
c) Enteroendocrine cell, because this organism does not need to absorb as many food products.
d) Paneth cell, because this organism will not need to secrete substances that destroy bacteria.

The answer is probably A.

A fruit and plant diet is high in carbohydrates but has little in the way of protein.

The other 3 options are more general and probably too necessary for survival to lose.

Answer: Option A

Explanation:

The chief cells in the alimentary canal of the organism releases an enzyme which is helpful in the digestion of the protein.

The name of the enzyme id pepsin which is not required much in the body of the organism who feeds on the plants and plant extracts.

This is because the plants have higher amount of carbohydrates in it and less source of protein.

Hence, for the digestion of cellulose, pepsin is not required.

The first bird that evolved the ability to fly now had habitats never before available and soon branched out into many different
dolphi86 [110]

Answer:

The correct answer is- adaptive radiation

Explanation:

Adaptive radiation is the evolutionary process which allow the evolution of many species from a single species because some population of that species get into an environment which is different from their old environment in terms of food availability, predators, etc.

So the first bird that evolved the ability to fly branched into many different species due to habitat change is an example of adaptive radiation. The most famous example of adaptive radiation is Darwinian finches which evolved from an ancestral species of south America that reached Galapagos island.

What does she need from the food she ate and the air she breathes so that she can go on her run? How do Rosa's body systems work
IgorC [24]

The missing part of the question is as follows:

Rosa eats a peanut butter sandwich for lunch. Peanut butter contains a lot of protein, and bread is mostly starch. Rosa plans to go for a run later this afternoon. Rosa is breathing normally.

Answer:

1. The food she ate is peanut butter and bread, the peanut is rich in protein while the bread is rich in carbohydrate which provides sugar (glucose) by breathing she gets oxygen in a sufficient amount to perform cellular respiration (aerobic) to carry out energy for running. Carbohydrates are a better choice of nutrients befors exercise as carbohydrates provide energy immediately.

Aerobic respiration provides a high amount of energy, 36 ATP to be specific, per cycle of cellular respiration.

2.  The carbohydrates (glucose) and oxygen she gets from food and breathing react together to perform aerobic cellular respiration to carry out maximum energy. By the digestive system and organs of this system, carbohydrates are broken down into glucose which is diffused into the blood.

Oxygen also diffused to blood from the lungs and heart with the help of the respiratory and cardiovascular systems of her body.

3. By the aerobic cellular respiration process takes place in the mitochondria of the cell helps in providing energy from glucose and oxygen by a three-step process:

Glycolysis, the Krebs cycle, and oxidative phosphorylation. Here glucose reacts with oxygen. Which ultimately provide 36 ATP molecules for the cell in a run.

A man interested in losing weight and increasing his fitness followed a strict diet and exercise regimen for three months. Body
sweet-ann [11.9K]

Answer:

All alternatives are correct.

Explanation:

During the weight loss process, cellular mitochondria transform the energy reserve arranged as body fat into heat, ATP, water and carbon dioxide. Therefore, none of these forms is "more likely", and fat loss occurs as a result of the release of all these products from cellular metabolism.
