I believe the answer is A
Answer:
<em><u>Homeostasis</u></em>
Explanation:
One function of the hypothalamus is to <u>regulate body temperature</u> known as homeostasis. Hypothalamus <u>maintains the body temperature to a normal temperature of about 37°C.</u> When you step out without the jacket in cold, your body temperature fall to 37°C. When the hypothalamus senses that you are too cold, it sends signals to your muscles that make you shiver and create warmth. This is called maintaining homeostasis.
Answer: Option D) cofactor that is an activator of the enzyme.
Explanation:
A cofactor is a non-organic component (usually a metal) of an enzyme or protein, that enhances its function. Good examples of Cofactors include iron in hemoglobin, zinc in carboxypeptidase.
Zinc at the active site of the enzyme, carboxypeptidase helps it in cleaving off aromatic amino acids.
Macromolecules in the mammals are of three different types, namely the carbohydrates, proteins, and the nucleic acids. Among these macromolecules, the nucleic acids are capable of self-replication. These encode the genetic information of the organism, and plays a vital role in carrying out an array of different functions of the body. One example of such nucleic acid is the RNA, or the Ribonucleic Acid.
Answer:
Absolutely, Genetic Polymorphism is observed
Explanation:
In genetics, Polymorphism refers to the regular existence of two or more different genotypes within a given species or population.
Definitely, the Clover leaf as described above exhibit genetic Polymorphism, bearing that the existence of the 3 genotypes: AA, Aa, and aa in Same species of Clover has been observed.
Note that this condition occurs because that natural selection is unable to pick a single trait above another; thus diverse phenotype of Clover leaves are observed.
