warm, salty water
B.
warm water with no salt
C.
cold water with no salt
D.
cold, salty water
B, cold with a high salt content, I believe. Since density is mass divided by volume, adding salt would increase mass. Temperature is related to kinetic energy and the distance between molecules/atoms of a substance. The hotter the substance, the more distance there is between particles. Generally cold water is more dense. Hope i helped :D
The stimulus is rain, response is using an umbrella and the outcome is not getting wet.

Elongation is a developmental process which is regulated by light and phytohormone. After elongation, plant cells begin to differentiate. During the period of differentiation cells of the root and the shoot apical meristems and the cambium mature, the cells cell evolve in to a specialized cells and begin to take on their individual functions.
Answer:
C- differentiate
Explanation:
b. a fish's tail fin.
c. a dog's front legs.
d. a mosquito's wings.
A bird's wings are homologous to a dog's front legs. Thus option C is correct.
Homologous structures shows the same structure, but may have a different function or same function.
Homologous structures have a common ancestor, this structure is an organ or bone that's in common between different animals that demonstrates an anatomical structure indicating that the animals share a common ancestor.
This is in contrast to analogous structures where two unrelated animals have structures with similar forms or functions due to convergent evolution.
