Rainforest cover only 2 % of the total surface area of the Earth but in spite of that about 50 % of plants and animals that live on the Earth live there.

By definition rainforests are forests that recieve high amounts of rainfall so you can actually find rainforests in Alaska for example (other examples: Canada, Asia, Africa, Latin and South-America)

About 1/4 of natural medicines are found in rainforests. 70 % or more of the plants that are used to treat cancer are found only in tropical rainforest on the planet.

Trees in tropical rainforests are so dense that it takes approximately 10 min for the rainfall to reach the ground from canopy.

A male cardinal's red color is an example of a trait affected by natural selection. The females of the species choose mates
kompoz [17]

Answer:

In the cardinals, if the females start using a different criterion than the color of the feather when they choose couple, most likely to happen is that decreased variation in the shades of red because no form of the trait is advantageous.

Explanation:

Options for this question are:

  • <em>Increased variation in the shades of red because the selection pressure has been relieved.</em>
  • <em>Increased variation in the shades of red because the cardinals try different ways to impress the females.</em>
  • <em>Decreased variation in the shades of red because no form of the trait is advantageous.</em>
  • <em>Decreased variation in the shades of red because the only reason for variation was selection pressure.</em>

In the context of natural selection, male cardinals court females using the coloring of their feathers as a form of sexual selection. This means that the shades of red in the feathers are a selection criterion in these birds, and the more visible shades represent an advantage.

But, if the selection criterion was not the color of the feathers, this trait would no longer represent an advantage in the competition between the males to be chosen as a mate. Instead, the trait that would determine sexual selection would be the one that experiences an increase in its variation<em>.</em>

subliminal perception.

Explanation:

Subliminal perceptions, also known as subliminal messages, are messages, either visual or auditory, that are presented just beyond the threshold of human perception. A subliminal perception may not be audible enough that the conscious mind might register it but be audible enough for the subconscious mind.

For example it might be an image transmitted briefly and unperceived consciously and yet perceived unconsciously.

Based on the given question, the number of prevailing cases carried from 2018 to 2019 is 2000, and the new diseases recorded in the year 2019 is 1000 (incidence). Therefore, the prevalence of the disease in 2020 will be 3000 cases.
