Considering the answers;
A. are still sibling species
B. shared a common ancestor more recently with each other than either did with the other two species
C.May merge into a single species if their hybrids remain fertile over the course of many generations.
D. A and B only
E. A, B, and C
The answer will be E.
If no other species can hybridize, then species W and Y are still sibling species, shared a common ancestor more recently with each other than either did with the other two species and also may merge into a single species if their hybrids remain fertile over the course of many generations.
They live every where
They can effect you and other organisms
They are microscopic
The answer is most likely "vascular system". Xylem tissue is a part of a plant's vascular system. Which is mostly responsiple for transportation (of water, food etc.) in a plant. The vascular system of plants is made of two tissues. One is Xylem and the other is Phloem. Phloem transports food from leaves to all other parts of the plant. And Xylem transports water and minerals (which are dissolved in the water) to the leaves.
So if you remove the <u>Xylem</u> tissue from a plant, its vascular system will be affected.
It is apart of cellular DNA an ATP, and is a major component of bones and teeth, it is often only available in limited quantities in the the environment.
The answer is B... im just making a guess so...
