Answer:
Mutation, an alteration in the genetic material (the genome) of a cell of a living organism or of a virus that is more or less permanent and that can be transmitted to the cell’s or the virus’s descendants. The genomes of organisms are all composed of DNA, whereas viral genomes can be of DNA or RNA.
take the test and it's correct
Answer:
Your question is unclear but, based on the context, it is clear to me that the point that comes after C (point D) refers to the process of evaporation. Please try to post a picture of the diagram and make your question clearer next time.
Explanation:
Please double check my answer but I believe its the Golgi Apparatus. ??
Answer:
The activities of enzyme depends on the <u>temperature</u>, <u>ionic</u> conditions and the <u>pH</u> of the surroundings.
Explanation:
<u>Effect of temperature on enzymes</u>
Enzymes show low level of functioning at lower temperatures. As the temperature is raised, the activity of the enzyme increases. The enzyme activity becomes optimal at a specific temperature. Beyond this temperature, the enzyme's activity rate starts to decline until it gets denatured.
<u>Effect of ionic conditions on enzymes</u>
Studies show that certain enzymes require some cations for functioning. But an increased amount of cations or anions can inhibit the functioning of the enzymes.
<u>Effect of pH on enzymes</u>
Each enzyme has an optimum pH at which it works best. If the pH is increased or lowered than this optimum pH, then the activity of the enzyme starts declining until it gets denatured. Most enzymes work best at pH 7.0
