Answer:
A step that is not part of natural selection is people select which individuals breed and which ones do not.
Explanation:
Natural selection is a process in which favorable or unfavorable environmental conditions determine the evolution of species, producing differences in their genotype over a long period of time.
As its name indicates, it is a natural selection, in which no intervention by people is contemplated, so that <u>people cannot determine which individuals breed</u>.
Natural selection implies that the characteristics on which the environment influences are inheritable, that there is genetic variability in the population and that the variability of these characteristics implies the ease of reproduction and survival capacity.
<em>The other options do form part of natural selection, since they are based on the three premises of this process:
</em>
- <em>Inheritable characteristics.
</em>
- <em>Genetic variability.
</em>
- <em>The variability of characteristics influences reproduction and survival.</em>
Secrete prolactin<span> (PRL), which initiates milk production in the mammary glands. Secrete adrenocorticotropic hormone (</span>ACTH), which stimulates the adrenal cortex to secrete glucocorticoids (like cortisol). Also secretes melanocyte-stimulating hormone (MSH<span>).</span>
<span><span>What is the distance covered by a vehicle
moving in a straight line during 20 s if the vehicle changes its speed from 10
m/s to 16 m/s during that time interval? In order to calculate the distance of
the boat we first have to identify the suited formula for acceleration in this
scenario. </span>
<span>Hence, a = vf – vi / t. Vi = 10 m/s Vf = 16 m/s T
= 20 seconds </span>
<span>Solution: </span>
distance = velocity x time</span>
Distance = 16 + 10 m/s / 2 x 20 seconds
Distance = 260 meters
Answer:
Because of cell differentiation
Explanation:
Multicellular organisms are organisms that have many cells in their body system, unlike unicellular organisms that have just one. However, these many cells contained in a multicellular organism are of different types performing different functions.
Although they all have the same set of genes encoding the same proteins in them, they are able to become different and perform different functions via a process called CELL DIFFERENTIATION. Cell differentiation is the process whereby cells of a living organism becomes specific in their functions as they divide. This is a result of the REGULATED EXPRESSION OF GENES. The genes in each cell are not expressed at the same time, hence, they have different functions.
