Answer:the relationship with the sun and the solar system is the same relationship to all physical bodies in which we are living at a speed governed by our perception at our vantage point in relation to how much gravity is acting upon us. Example: Say you were to fall into a black hole. At the point of no return at the event horizon your time would begin to slow down as seen from an outsider watching you fall. This will occur until to that observer sees you stop entirely in time. You however fall faster as faster but for ever. Till time is over. So all things are relative to each other in only one absolute way. Gravity control observed time.
Explanation:
The tissue that water travels up from the roots to shoots in a deciduous tree is xylem.
<h3>
What is xylem?</h3>
- Xylem is one among the two types of transport tissue in vascular plants, the opposite being phloem.
- Transport water from roots to stems and leaves is the main function of xylem, but it also transports nutrients.
- The word xylem springs from the Ancient Greek word ξύλον (xylon), meaning "wood"; the best-known xylem tissue is wood, though it's found throughout a plant. The term was introduced by Carl Nägeli in 1858.
- The long tracheary elements are the most distinctive xylem cells that transport water. Tracheid and vessel elements are distinguished by their shape; vessel elements are shorter, and are connected together into long tubes that are called vessels.

Describe the advantage of scientists being organised into teams all around the world to work on the human genome project.
Answer:
prezygotic ... behavioral isolation
Explanation:
Prezygotic barrier is a reproductive barrier that occurs when fertilization is prevented from occurring as a result of isolation leading to prevention of copulation, and as such there is no fusion of gametes for fertilization to take place, and eventually formation of zygote. Zygote is not formed as fertilization does not take place.
Behavioral isolation is a prezygotic reproductive barrier that prevents two or more different species to copulate together in order for fertilization to take place due to differences in behavior that is unique to each species. One of such behaviors is mating calls.
As a result of the differences in mating calls which is unique to each species of frogs mentioned in the question, only members of each species get attracted to themselves and mate with their members, thereby making it almost impossible for the three different species of frogs to mate together.
I would say b and a don't quote me if I'm wrong :P
