Answer:
A
Explanation:
In tropical rain forests, rainlevels fluctuate in that pattern throughout a year.
When one frog's heart is stimulated and the extract from this stimulated heart is transferred to the heart of another non-stimulated frog, the rate of heart beat of the second frog will be increased too because of the transmission of the impulses via the synapses. Hence, this observation proves that the transmission of the impulses at the synapses is a chemical event.
First of all, what is a hotspot?
A hotspot, is a place with a hotter temperature in relation to its surroundings.
So, when we think of "biodiversity hotspot", what exactly does that mean?
It's a place with a higher biodiversity in relation to its surroundings, but also with more concentration of species.
So, that's why forests are considered a biodiversity hotspot. If you want some visual content, try finding a geographical map of Africa. In some desert regions you'll see green spots (some really big). These are forests. The interesting thing about them, is when you search their biodiversity, you'll see what a biodiversity hotspot looks like

Stomata play an important role in photosynthesis as they allow the plant to absorb carbon dioxide from the environment. In exchange, stomata allow oxygen, which is a waste product of photosynthesis, to be released. In the process, water vapor is also lost as the internal parts of the leaves are exposed. To reduce exposure, stomata are found on the underside of the leaves. They are protected from the sun as excessive heat can increase the rate of water vapor leaving and thus wither the plant. Stomata also have guard cells around the epidermis that close when too much water is being lost.
