Because migration and and other seasonal movements can affect the possibility of finding a mate, stresses, that could affect offspring survival(can vary with season), and also availability of thing that are available for the offspring.
The mother actually gives more DNA to a baby more than the father because of the little organelles, aka the mitochondria that live inside your cells are only to be received from your mother.
But in DNA, it can vary who's side you can get more of, and in some rare cases, equally. This is because dominant genes carry out around 75% of the time and genes that are recessive can carry out 25% of the time, depending on the genetics of both the mother and the father. Example, brown eyes are a dominant gene over blue eyes, so there is a 75% chance that the baby will have brown eyes and a 25% chance that the baby has blue eyes if one parent has the brown eye gene and one has the blue eye gene.
I hope this helped!! :D
If NOCTURNAL ACTIVITY is one of the choices, that's your answer.
1.Fish gills are organs that allow fish to breathe underwater. Most fish exchange gases like oxygen and carbon dioxide using gills either on side of the pharynx.
2.Gills are branching organs located on the side of fish heads that have many, many small blood vessels called capillaries.
3.The colour is red
4. A Gill filaments project from each arc between the dorsal upper and ventral lower surfaces of the filaments.
They took different paths to discover energy, but both found that energy can be exerted, and conserved
