The correct option is D.
Cellular respiration is the process by which the body breaks down the sugar molecules that are eaten in food with the aid of oxygen and covert them into energy, carbon dioxide and water are also produced as by products. Cellular respiration and fermentation are both involved in the breaking down of sugars but cellular respiration occurs in the presence of oxygen while fermentation occurs in the absence of oxygen. Carbon dioxide is breath out by the lungs during cellular respiration.
It all depends on the trait. If the dominant is more common that the recessive trait then it is more likely to a dominant trait in the gene pool. But if the recessive trait is more common in the gene pool then you will have a recessive trait. Does this make sense? Let me know if I'm right!
The correct answer is letter C, in most primates, the inability to move the ear has been replaced by the ability to stand upright on two legs. This is because movement was much of a need to these primates than hunting for food. They needed to be agile to locate specific places where sources of food are abundant.
Answer:
Carbohydrates
Explanation:
Carbohydrates are made up of carbon, hydrogen, and oxygen make up carbohydrates. These biomolecules are the primary sources of energy of living things, including humans. They are found in living organisms in the form of sugars, fibers, and starches. There are different types of carbohydrates like monosaccharides, disaccharades, and polysaccharide.
