Answer:
evolution of populations over time
b. natural selection.
c. descent with modification.
d. acquired characteristics.
Answer: Artificial selection.
Explanation: Artificial Selection can be defined as the intentional reproduction of the individuals that have the desired trait. The organism having the desired character breed together to give rise to the individual having the desired trait.
The dairy farmer choose to breed the cows that give most milk. This is the desired character that we want in the offspring.
Well, i took the test and i put artificial selection and got it right. The definition of artificial selection is "The breeding of plants and animals to produce desirable traits" So the answer is A
B. 40°
C. 80°
D. 100°
B. 40°
m∠BAC = 40°
But, angles in a triangle adds up to 180 degrees, therefore;
m∠BAC = 180 - (m∠ACB + m∠ABC)
= 180 - (50 + 90)
= 180 - 140
= 40°
Thus; m∠BAC = 40°
The solution of m∠BAC is mathematically given as
m∠BAC = 40°. This is further explained below.
The angle formed by two crossing lines or surfaces, commonly expressed as a number of degrees.
Generally, the equation for angle m∠BAC is mathematically given as
m∠BAC = 180 - (m∠ACB + m∠ABC)
m∠BAC = 180 - (50 + 90)
m∠BAC = 40°
In conclusion, m∠BAC = 40°
