Explanation:
Animals do not possess any sort of cell wall since animals always move, they are not static in one particular place, therefore they need to be flexible.Animal cells lack the thick cell wall that plant cells have, so there is no need for a central vacuole to exert pressure on the surrounding cell

</span>Acceleration = Velocity / Time
Greater velocity / Lesser time
Greater Velocity = greater acceleration
Proportionality or variation is state of relationship or correlation between two variables It has two types: direct variation or proportion which
states both variables are positively correlation. It is when both the
variables increase or decrease together. On the contrary, indirect variation or proportion indicates
negative relationship or correlation. Elaborately, the opposite of what
happens to direct variation. One increases with the other variables,
you got it, decreases. This correlations are important to consider
because you can determine and identify how two variables relates with
one another. Notice x = y (direct), y=1/x (indirect)</span>
The correct answer is B. pollution.

Explanation:
Because baldness is a sex-linked trait.
In other words, men are simply more likely to express the trait for baldness than women are, because they only need one set of genes for baldness, while women need two.
If, for example, for each gene there is a 1/2 chance that the gene will be for baldness and 1/2 that it will not, then men have a 1/2 chance (because 1/2^1 = 1/2) of being bald, while women have a 1/4 chance (because 1/2^2 = 1/4) of being bald.
This is the reason it's called "male-pattern baldness": it is more common in males. However, this does not explain nor rule out the dearth of women with baldness-women can get it too: it's just less common
The answer is; catalyst
These proteins are called enzymes. They work by lowering the activation energy of reactants and hence speed up the biochemical reaction. They are not affected in the process hence one enzyme molecule can catalyze many reactions. An example of such an enzyme is carbonic anhydrase that enables carbon dioxide to dissolve in blood plasma as carbonic acid.
