The answer is a type of fertilizer.

<span>An independent variable is variable that is not affected in the experiment. It is what experimenter controls. On the other side, a dependent variable is called dependent because it depends on the independent variables. It is what is affected during the experiment.
In this case, the growth of pea plants depends on different types of fertilizer. So, the growth of pea plants is the dependent variable and different type of fertilizer is the independent variable.</span>

Answer:

C. Dark Moths had a survival disadvantage in industrial Dorset

Explanation:

Looking at the graph, you can see that the Dark Moth, compared to the Light Moth actually had a survival advantage.

I won't be explaining the why's to this phenomena, considering that the question is based solely on the graph.

Compare the two bars of Dorset. The Light Colored moths are represented by the green graph while the Dark colored moths are represented by the orange bar. The orange bar extends further that the green bar, showing that they recovered better than the other. So this means they were at an advantage and NOT at a disadvantage.

What is the process of reproduction between human and animals?​
Dovator [93]
All reproduction is basically the division of a cell into more cells.
Humans ARE animals so the same system applies to all these organisms.
Each individual starts as a single cell - an ovum - with a full set of the species' chromosomes/DNA - in humans always 22 and an X.
Animal species such as cats and dogs have their own set, unique to their species, with the ovum always found in the female body, stored in the
