Whats are the pros and cons of a endoskeleton?
Softa [21]

Well, an endoskeleton is an internal skeleton, like humans have. Pro: Bones do not get broke as easily, since they are inside of the body. Bones that break also heal more quickly in an endoskeleton, since they have tissue and blood surrounding it and transferring nutrients. Con: The flesh can get easily damaged. There is no shedding with endoskeletons, so a new skeleton cannot be grown in the event of an injury.

What types of bonds hold nitrogenous bases together?
Virty [35]

However, the nitrogenous bases, which are adenine, thymine, cytosine and guanine, pair up so that cytosine only pairs with guanine and adenine links up with thymine.</span>
