in the main reproductive hormones are oestrogen and testosterones. Œstrogènes causes eggs to mature in overuse once a girl hits puberty. These are then released at regular intervals during the menstruel cycle
Simple diffusion, if I’m reading your question right
The equivalent versions in reptiles are scales
(analogous to the cuticle) and the amniotic egg (analogous to the seed). Recall
that the cuticle seals plant surfaces and helps plants conserve water, and the
seed helps derived plant groups to reproduce effectively on dry land.
If it's letter choice then it would be : all of the above
Active transport would be required because in order to move across a membrane against the concentration gradient, energy is needed. Active transport uses energy to help molecules/ ions achieve this movement.<span>
