Well this is not true.
<span>Chemical transmitters can only stimulate SPECIFIC receptor sites to initiate an action.</span>
Answer:
The answer that are true are:
1) A: Horses and Mules can be bred but their offspring is typically sterile. This could be an example of hybrid breakdown.
2) C: One species of sea turtle mates during the early spring and a closely related species mates during late spring. This is an example of temporal isolation.
3) D: One species of sea urchins can not fertilize another closely related species because the eggs do not have a receptor for the sperm. This is a good example of gametic isolation.
4) E: Damselflies have sensory receptors that are sensitive to touch (tactile cues). Two related species of damselflies are unable to mate because their touch cues are not compatible. This is a good example of mechanical isolation.
The Darwin's theory of evolution states that the organisms evolve through the process of the natural selection of the favorable genetic variations gradually over time. Through this process of the evolution, new species are developed over time. A single population may give rise to different species. These newly evolved species share similarities will each other as they have the same ancestor.
Hence, the given statement is 'true'.
Answer:
gravity
Explanation:
gravity is the reason why regular things can't float, why we land when we jump, and why we can't fly.
gravity pulls us towards the ground, towards the center of the earth (inner core)
<span>Prostatitis. The above examination, associated with a history of dysuria, frequency, and incomplete voiding, should lead you to suspect acute prostatitis. Prostate cancer, colon cancer, and polyps should not ordinarily cause systemic symptoms such as fever.</span>
