Answer:
The most appropriate answer would be b. gene flow at work.
Transfer of pollen grain forms the example of vertical gene transfer that is, transfer of a gene from parent to the offspring.
A pollen grain is the male gamete of the parent plant. It contains the genetic material or information of the plant.
It is pollinated or transferred to the stigma of the plant of same species with the help of air, water, bees et cetera. Successful pollination results in the formation of the zygote.
Thus, gene or genetic material is transferred from parent plant to the offspring. Hence, the student can use "gene flow at work" as the caption of the picture.
I believe the answer you're looking for is:
Condensation- If the air cools, then water vapor molecules slow down and some can not remain a vapor. They cluster in the air to form tiny liquid droplets. This is called condensation. In clouds, the liquid droplets formed by condensation are small and light enough that they stay in the air.

Answer:
a complex of vesicles and folded membranes within the cytoplasm of most eukaryotic cells, involved in secretion and intracellular transport.
Abiotic factors are factors that include non-living parts of the environment which could be significant or essential to living organisms. Water is a non-living environment and it helps in giving life to plants and other organisms. Thus deemed abiotic.
