Answer:
1. The female ileum does not project far above the sacroiliac joint
2. The body of the pubis is longer in females than in males
Explanation:
Pelvis refers to the complex of bones in the male and females of humans and other primates which joins the upper trunk to the legs. The pelvis allows the space for the urinary bladder, Intestine and the reproductive organs.
It is the presence of these reproductive organs and associated functions which changes the shape of the pelvis in male and female like the females have broader pelvis for the growth of the baby inside the womb and the childbirth whereas the males do not have wider but narrower bones.
The ilium bone in the females does not project far above the sacroiliac joint formed between the sacrum and the ilium bones.
Thus, the selected option is correct.

Mutations can be beneficial, neutral, or harmful. They are also random. The other thing to note is that only mutations in cells that are passed onto the next generation are important to evolution of the species.
Evolution absolutely depends on mutations because this is the only way that new alleles and new regulatory regions (that control the expression of alleles) can happen.
Neutral mutations don't mean much. However, harmful (deleterious) or beneficial (good) mutations matter greatly.
If a mutation is deleterious, then the resulting offspring likely will die and that mutation will not be passed onto the next generation. On the other hand, beneficial mutations could possibly result in new structures or new functions for proteins that are helpful to the survival of the organism. Natural selection (survival of the fittest) would then rule in favor of these traits and will therefore be passed down into the next generation. Overtime, if these traits are heavily favored, they will become more predominant in the population.
