In a population of fruit flies grown in laboratory conditions, a new phenotype arises. Instead of the typical red eyes, a purple

-eyed
individual is seen. This individual survives to adulthood and is able to mate with other flies. Two students studying the fruit fly
population discuss the origin of the purple-eyed fruit fly. One student insists that the fly came from outside of the original fruit fly
population. The other student claims that the fly originated from within the laboratory fruit fly population. Which statements defend
the claim of student two that the new phenotype originated from within the fruit fly population?

In a population of tomato plants mean fruit weight is 60 g and narrow-sense heritability (or realized heritability - h2) is 0.3.
Alla [95]

Answer:

The mean weight of the progeny is 66 grams

Explanation:

Given -

Mean fruit weight of tomato plant (M1) = 60 g

Narrow sense heritability (h2) = 0.3 g

Mean weight of tomato plant selected for artificial selection (M0) = 80 g

h_2 = \frac{M_2 - M_1}{M_0 - M_1}

Substituting the given values in above equation, we get -

0.3 = \frac{M_2 - 60}{80 -60} \\0.3 = \frac{M_2 -60}{20} \\6 = M_2 -60\\M_2 = 6 + 60\\M_2 = 66

The mean weight of the progeny is 66 grams

In the generation of most anions, the energy change (kj/mol) that _______ an electron is ________.
stepan [7]

The answer is D. An anion is a negatively charged ion, which means it has accepted an extra electron (s) from a donor ion (cation). To add an electron, energy has to be released so that the electron can be less excited and go back to its orbital level. The released energy is equivalent to the energy required to remove the electron from its orbital level.
