Well, what do you need help with?
This varieation can be justified because since they had different variations they probably had different niches which led them to evolve differently,this will help because the two species will have no competition
Answer:
All the above
Explanation:
A stem is one of two main structural axes of a vascular plant, the other being the root. It supports leaves, flowers and fruits, transports fluids between the roots and the shoots in the xylem and phloem, stores nutrients, and produces new living tissue.
Stems have four main functions which are:[1]
Support for and the elevation of leaves, flowers and fruits. The stems keep the leaves in the light and provide a place for the plant to keep its flowers and fruits.
Transport of fluids between the roots and the shoots in the xylem and phloem(see below)
Storage of nutrients
Production of new living tissue. The normal lifespan of plant cells is one to three years. Stems have cells called meristems that annually generate new living tissue.
That is true.
These are the three types:
Igneous- form when magma cools down and hardens.
Metamorphic- form under earth's surface after particles undergo intense heat and pressure.
Sedimentary- forms when different layers of sediment accumulate on top of each other and harden creating a solid piece.
Hope it helped!
Answer:
B One allele from each parent
Explanation:
You have dominant genes (brown eyes) and recessive genes (green eyes)
In order for a child to be born with brown eyes only one parent needs to have brown eyes. Having green eyes is recessive so either both parents need to have green eyes or neither of them needs to have them. But if one parent has green eyes and the other has brown eyes, then the brown eyed gene will almost always dominate the green eyed one.
I hope this helps! :)
