Hope this helps : )
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:
Urinary system filters your blood, removing waste and excess water.
Your digestive system breaks nutrients into parts small enough for your body to absorb and use for energy, growth, and cell repair.
The immune system is a complex network of cells and proteins that defends the body against infection.
Answer:
C) dwarf mistletoes, which parasitize particular species of forest tree
Explanation:
Uniform dispersion is observed in plant species that inhibit the growth of nearby individuals. For example, the sage plant, salvia leucophylla, secretes toxins, a phenomenon called negative allelopathy. Animals that maintain defined territories, such as nesting penguins, also exhibit uniform dispersion.
In lodgepole pine stands, spread of dwarf mistletoe into young trees is more extensive from single, isolated residual trees than from relatively uniform, dense, even-aged stands of residual trees.
