Gonads are the body structures that produce sex cells. Sperm are the male sex cells. Eggs are the female sex cells. Chromatin are threadlike DNA found inside the sex cells.
The function of a bone that results from its relationship
with a skeletal muscle is that it engage in or allows movement of the limbs in
which we could see that both the bone and skeletal muscle are working together in
order to produce the limb’s movement.

Survivorship curve = so, first of all, it's a curve, as in a graph.
It describes "survivorship" - the rate of survival, in other words: out of 100 organisms that are born, how many survive. This rate is different among species, for example, most humans live out to most of their life span, and almost all can survive well beyond a reproductive age.
However, in frogs for example, many many individuals are born, but only few can survive to adulthood: most die very young, before reproductive age.
So if you hear about a new species: let's say dogs, and you want to know how long they would live, you would look at their sirvivorship curve (and in some breeds of dogs, those that are likely not to be in shelters, but in homes, the survivorship curve would be similar as in humans: almost all individuals born can live long.
