<span>The answer is letter B.
Some bacteria that interact with humans can cause benefits to the body when they are small in numbers. An example of this bacteria is the lactobacilli which can be found as an ingredient in some drinks that can purify the digestive system. Though, they can only be taken in small amounts because they may overwhelm the immune system which can cause major complications within the internal organs. Some bacteria that interact with humans can be harmful because of their capacity to divide at a fast rate. <span>

Answer:(a)elastase
Explanation:
Elastase is a protease enzyme the function involves the cleavage of peptide bonds after amino acids with small side chains. This is responsible for cleaving the peptide bonds between the elastin fibers and aids in digestion of the elastic protein.
Thus the elastase cleaves the protein fibers this can be said that the elastase is a non-fibrous protein.
Dermis contains receptors but not a sub-cutaneous.

Aerobic respiration is a biological process that takes energy from glucose and other organic compounds to create a molecule called Adenosine TriPhosphate (ATP). ATP is then used as energy by nearly every cell in the body -- the largest user being the muscular system. Aerobic respiration has four stages: Glycolysis, formation of acetyl coenzyme A, the citric acid cycle, and the electron transport chain.
The first step of aerobic respiration is glycolysis. This step takes place within the cytosol of the cell, and is actually anaerobic, meaning it does not need oxygen. During glycolysis, which means breakdown of glucose, glucose is separated into two ATP and two NADH molecules, which are used later in the process of aerobic respiration.
The next step in aerobic respiration is the formation of acetyl coenzyme A. In this step, pyruvate is brought into the mitochondria to be oxidized, creating a 2-carbonacetyl group. This 2-carbon acetyl group then binds with coenzyme A, forming acetyl coenzyme A. The acetyl coenzyme A is then brought back into the mitochondria for use in the next step.
The third step of aerobic respiration is called the citric acid cycle -- it is also called the Krebs cycle. Here, oxaloacetate combines with the acetyl coenzyme A, creating citric acid -- the name of the cycle. Two turns of the citric acid cycle are required to break down the original acetyl coenzyme A from the single glucose molecule. These two cycles create an additional two ATP molecules, as well as six NADH and two FADH molecules.
The final step in aerobic respiration is the electron transport chain. In this phase, the NADH and FADH donate their electrons to make large amounts of ATP. One molecule of glucose creates a total of 34 ATP molecules.
Hope this helps!
