In Natural selection, who/what makes the decision about which traits are desirable and get passed to future generations? In Artificial selection, who/what makes the decision about which traits are desirable and get passed to future generations?

please help me with these two questions complete sentences please thank you! This is for 50 points and BRAINLIEST.

Artificial selection, also called "selective breeding” is where humans select for desirable traits in agricultural products or animals, rather than leaving the species.

i'm assuming that the correct answer is indeed the first one/ "a"..

the ideal gas law equation is as follows

pv = nrt

where p - pressure

v - volume

n - number of moles

r - universal gas constant

t - temperature

so if the pressure, volume and temperature are already known

we are left with n and r

since r is the universal gas constant that has a known fixed value then r too is known

so we are left with 'n'

once we know temperature volume and pressure

we can find the number of moles of gas present using the ideal gas law equation

this is not my own answer, this is an answer for the same question by the user blahblahmali. i do not claim ownership of this account.
