nirvana33 [79]
Work is said to be done when an object moves due to a force applied. Work is calculated by multiplying the force applied and the distance traveled due to the force. It is expressed as:

W = Force x distance

W = 84 J = F (7.0 m)
F = 12 N

Hope this answers the question.

6. species Closely related of orchids never mate in the wild because they bloom at different times. This is an example of ______
Dimas [21]

Answer:

temporal reproductive isolation

Explanation:

The correct answer would be temporal reproductive isolation.

<u>Reproductive isolation</u> generally refers to series of biological mechanisms or processes that prevent members of different species from mating/fertilization or prevent the product of their mating to be invalid.

Some reproductive isolation processes prevent members of different species from mating or prevent fertilization as a result of mating. These processes are known as pre-zygotic reproductive isolation mechanisms.

Some other processes ensure that the product of fertilization (when it occurs) is invalid. These are known as post-zygotic isolation mechanisms.

<em>A good example of the pre-zygotic reproductive isolation process is </em><em>when closely related by different species bloom at different times</em><em>. This will prevent mating or cross-pollination to happen between the different species. This is known as temporal reproductive isolation.</em>
