The sugar-phosphate backbone of DNA is held together by covalent bonds.     The strands of DNA are joined by hydrogen bonds (H-bonds) between the nitrogenous bases o â¦ n either side. Adenine is joined to Thymine by 2 H-bonds. Cytosine is joined to Guanine by 3 H-bonds.
The mother will leave the nest and the newly hatched chicks sometimes for long periods of time to eat, drink or take a bathroom break. In some species the father will then take over nest duties, but in hummingbirds, itâs up to the mother to tend the eggs and the babies.

A hummingbird eggs will be white in color and only about the size of a pea or jelly bean.ince it is quite difficult to locate a hummingbirdâs nest and therefore most of us may never see one for ourselves, I thought I would share with you some information about the hummingbirdâs eggs and the length of their gestation period. In most cases, a female hummingbird will lay two eggs.
