Receptors<span> are generally transmembrane </span>proteins<span>, which bind to signaling molecules outside the cell and subsequently transmit the signal through a sequence of molecular switches to internal signaling pathways</span>
Answer:
For natural selection to occur, it is true that there must be genetic variation in the population.
Explanation:
According to evolution, natural selection implies the changes that occur in the genotype of a species, due to the effect of environmental factors, and which guarantee its survival through adaptive evolution.
For natural selection to occur, three fundamental conditions must exist:
A trait that can be inherited from one generation to another.
The trait is subject to variability between subjects of the same species.
Genetic variability can determine the possibility of reproductive success and survival.
Therefore, a necessary factor for natural selection to occur is that genetic variability exists in the population.

Answer:
The correct answer is - priming.
Explanation:
Priming is a phenomenon that explains the behavior of an individual when an individual experiences a certain stimulus that influences response to a subsequent stimulus, unknowingly of the connection. This effect is known as the priming effect.
In this case, watching a cartoon of a rabbit acts as the stimulus that influences the response of identifying the image of duck as a rabbit. He is experienced priming effect.
Cells are made up of molecules, that are made up of atoms, so no. Cells are bigger than atoms :)
