Answer:
negative feedback
Explanation:
The negative feedback system is the most common in the body, being considered by many authors the primary mechanism for the maintenance of homeostasis. It causes a negative change from the initial change, that is, a stimulus contrary to the one that led to the imbalance. In the case of the above question, when the ambient temperature increased, your body began to sweat to lower the temperature, that is, your body is trying to make a stimulus contrary to what is happening in the environment, so we can state that your body is going through a negative feedback system.
It depends on the energy released by radioactive decay of
uranium and other heavy long lived isotopes in the Earth's core and the
internal heat of the Earth is produced by the original heat of formation that
resulted from accretion and gravitational contraction.
The different combination of alleles for two genes must be due to "Crossing Over" [ Process occurs after fertilization, inter-changing of characters ]

Answer:
A
. proteins can take a variety of shapes, and nucleic acids tend to form linear chains
Explanation:
Proteins are consist of 50 and 2000 amino acid long and can take variety of shapes in living organisms. Two types of proteins that found in living cells are globular proteins and fibrous proteins and they have different shapes. Example of globular protein is hemoglobin and fibrous proteins are hair and nails, and collagen.
Nucleic acids tend to form linear chains from the monomers called nucleotides. Nucleotides have three components: nitrogenous base. phosphate group, and pentose sugar (5-carbon sugar) that together forms a definite linear shape. It is found in DNA of living organisms.
Hence, the correct option is "A
. proteins can take a variety of shapes, and nucleic acids tend to form linear chains".
