Answer:
One of the most typical ways that plants like ferns move is through a process known as phototropism. Essentially, they move and grow towards light .Plants may also move or grow in response to other stimuli, in addition to light. They can grow or move in response to physical touch, in response to a chemical, or toward warmth
Fungi are the most likely but some protista and monera also absorb
Sex chromosomes determine one's gender. Of the 23 chromosomes humans have, one of the pairs are sex chromosomes. Autosomes make up 22 pairs of the chromosomes. They determine other traits of the body like hair color, eyes, or skin.
Hello!
Yes, the selection in this case would be natural selection because whales of maximum length are mating naturally on their own choice. We are not maintaining and experimenting on them for the analysis that what will be the size of their offspring, if we do that, that is artificial selection.
Why it is natural selection?
Natural selection is the process where organisms with favorable traits are more likely to reproduce. In doing so, they pass on these traits to the next generation. Over time this process allows organisms to adapt to their environment.
Here both whales are of good size (favorable trait) and have definitely better chances of mating and producing fertile generation.
Hope it helps! :)
