Answer:
Enzyme
Explanation:
Enzymes are the bio-catalyst that serve to accelerate the metabolic reactions occurring in a living cell. All the metabolic reactions of organisms are catalyzed by enzymes. Each metabolic reaction is catalyzed by specific enzyme. Absence of that particular enzyme leads to absence of the respective product. Since genes code for protein which regulate the specific trait, absence of enzyme does not allow the expression of that trait.
Example: Absence of enzymes for chlorophyll synthesis would lead to absence of chlorophyll from leaves of the green plants.
D the correct answer is d
Answer:
The traits of a living thing depend on the complex mixture of interacting components inside it. Proteins do much of the chemical work inside cells, so they largely determine what those traits are. But those proteins owe their existence to the DNA (deoxyribonucleic acid), so that is where we must look for the answer.
This refers to a trait that should be able to be treated with antibiotics but instead the trait has built up a resistance to this trait, sometimes this will even make the trait stronger. This can become fatal if the trait is resistant to all antibiotics available
<span>The peripheral nervous system (PNS) is one of the two major components of the body's nervous system. In conjunction with the central nervous system (CNS), the PNS coordinates action and responses by sending </span>signals<span> from one part of the body to another. The CNS includes the brain, </span>brain stem<span>, and </span>spinal cord, while the PNS includes all other sensory neurons, clusters of neurons called ganglia, and connector neurons that attach to the CNS and other neurons.
