The answer is the central dogma of molecular biology.
The central dogma of molecular biology explains that the sequence of DNA specifies the sequence of mRNA, which, further, specifies codes for the sequence of proteins. Simply, DNA codes for RNA and RNA codes for proteins. The central dogma was first stated by Crick in 1956.
The question is incomplete as it does not have the options which are:
A.) Presence of genitalia.
B.) Shape of genitalia.
C.) Presence of a scrotum.
D.) Composition of accessory fluids.
Answer:
Option-A
Explanation:
The reproductive system which is the system formed by the organ which is involved in the reproduction in an organism. These reproductive organs are known as genitalia. Since reproduction is one of the criteria of the cellular organisms, reproduction is possessed by all the organisms on Earth.
The animals which bear the reproductive structures therefore always show the presence of both internal and external reproduce organs like testes, Vas deferens as internal organs and penis and scrotum as external organs.
Thus, Option-A is correct.
3% of earths water is usable as a fresh water source
Answer:
i think it's "C"
Explanation:
because if both have similar structure then just have some relation
Answer:
An important regulation process that connects various parts of a system is feedback.
Explanation:
A reaction inside a biological system—a molecule, tissue, species, or population—that affects the behavior or performance of that system is known as feedback. It essentially involves the regulation of a metabolic pathway by the activity's byproducts.
Both positive and negative feedback is possible. Negative feedback is indeed a component of any feedback mechanism that keeps things in balance. Positive feedback in biology occurs far less frequently. Whenever a change in variable results in a reaction that undoes the original change, this is known as negative feedback. A reaction is generated by a change in a factor when there is positive feedback. For instance, a warm-blooded species like a whale keeps a greater body heat to improve the internal equilibrium and while a cold-blooded animal such as fish retains a lower temperature of the body in accordance with the surrounding environment.
