Answer:
Linnaeus primarily used physical characteristics.
Explanation:
Convergent evolution explains that non-related species can develop similar traits due to adaptations that happened while living in similar ecosystems. For example sharks which are a type of fish have similar body plans to dolphins, a type of mammal.
Chemical weathering refers to the erosion or total disintegration of rocks that are caused by chemical reactions and not by mechanical processes. Usually water and other liquid substances causes this to occur. Skyscrapers or buildings are prone to chemical weathering because they are constantly exposed to precipitation and other elements in the atmosphere. In rocks, when this process happens they tend to crumble and form smaller rock pieces. It is important to note that during this stage, the end product is a totally different substance than its original phase.
Below are the questions:
A) A hovering mosquito is hit by a raindrop that is 45 times as massive and falling at 8.9m/s , a typical raindrop speed. How fast is the raindrop, with the attached mosquito, falling immediately afterward if the collision is perfectly inelastic?
<span>B) Because a raindrop is "soft" and deformable, the collision duration is a relatively long 8.0 ms. What is the mosquito's average acceleration, in g's, during the collision? The peak acceleration is roughly twice the value you found, but the mosquito's rigid exoskeleton allows it to survive accelerations of this magnitude. In contrast, humans cannot survive an acceleration of more than about 10 g.

Below are the answers:
a. <span>MU = (M + m)V; where M = 45 m, U = 8.9 m/s, find V = ?. V = (45/46)*8.9 = 8.7 m/s
</span>
b. <span>F = m dV/dT = m 8.7/8E-3 = m 1.0875E+03; so G = 1.0875E+03/9.8 = 111 G's.</span>
Answer:
Nitrogen
Explanation:
Nitrogen
The most abundant naturally occurring gas is Nitrogen (N2), which makes up about 78% of air (oxygen)
hope this helped!
<span>The guanine percent is 30. This is because the other 30% of the 60% is cytosine. Getting back to adenine, it always partners up with thymine. So it would be 20% thymine and 20% adenine, add those portions to the 60% of the other two, mentioned above and you have 100%.</span>
