Animal behavior and offspring success
Do male birds always attract female birds like this or is there some other way?
Not always. When it comes to birds, the male usually attracts the female. This can be done through attractive looks, flying, fighting, and, of course, offerings.

The reproductive system review
the sperm enters through the the cervix through the mucus and swims up the uterus till it meets the egg and till it fertilizes
That's true. After it swims up to the uterus, however, it goes into one of the two fallopian tubes, where it fertilises.

Prokaryote structure
can eukaryotes have flagella and pilli? or is that only for prokaryotes?
Yes, and the flagella of motile bacteria differ in structure from eukaryotic flagella. However, Eukaryotes do not have pili or fimbriae.

The endomembrane system
Why are mitochondria, choloroplasts, and peroxisomes not included in the endomembrane system?
I believe that they are not included into the endomembrane system because none of them receive anything from the Golgi apparatus. Hope this will help you:)

How do plants you buy at the store, stay alive in just water, and no dirt? Also, why are some plants supposed to get direct sun? Thanks!
the plants are already being put in mineral water. It isn't the dirt that helps the plant it is the minerals that help it grow.
