Answer:
protect the cell from invading phages
Explanation:
<em>The natural role of the restriction enzymes is to protect the cell from invading phages.</em>
The restriction enzyme is an enzyme that functions by cutting DNAs from some pre-identified sites on the DNA. They are primarily found in bacteria where they protect the cell from invasion by foreign DNA from phages.
<u>Once a phage invades a bacterium, the restriction enzyme quickly acts by cutting the phage's DNA into smaller pieces, leading to the destruction of the DNA and hence, the protection of the bacterium cell.</u>
I know its not A or C, I believe the answer is D. Ultraviolet Light.
Answer: Wear eye protection, rubber gloves
Handle acid with care and follow CLEAPSS or SSERC guidelines on its use.
<span>Neither. You need a nutritionist. Biochemist and food scientists could peripherally be involved by seeing that food is processed in such a way as to preserve the nutritional value of the food. (e.g., seeing that the vitamins are not degraded by processing) and contaminates and bacteria are not introduced.</span>
Answer: urea disposal
Explanation:
<u>The liver, which is the largest organ in the human body, performs three vital functions of the organism: detoxification, synthesis and storage. </u>
The liver acts as an authentic filter that collects and eliminates numerous toxins, such as ammonia, or toxins that we ingest, such as alcohol (it performs a biotransformation of toxins). Our liver is also responsible for the metabolism of carbohydrates, lipids and proteins, secreting bile, an essential element for the digestion. It also prevents bleeding through a coagulation process. And it is a container of vitamins (A, D, E, K) and glycogen (carbohydrates), while energy is stored in the form of sugar, made available to our organization.
The urea cycle takes place primarily in the liver. Organisms convert ammonia to a less toxic substance, such as urea, via the urea cycle. <u>Then it is released into the bloodstream where it travels to the kidneys and is ultimately excreted in urine. </u>
So, the liver is involved in the production of urea, but the kidney is responsible of its disposal.
