Answer: Experiment.

Explanation:

Suppose that we have two related variables, A (independent) and B (dependent)

We could design an experiment where we can manipulate the value of A at will, and we also can observe how the variable B changes.

This is called an experiment, where the objective is to see how the variable B is related to the variable A, and then try to make a model that explains this relationship.

A species of fly has two alleles for the length of their legs. The allele for long
Artyom0805 [142]
The answer is A. 0.54.

In a population p+q=1 (we have 2 alleles only).

The question states that 0.21 of the population(21%) have short legs meaning they are q^2.

So q=rad0.21=0.4582.

And p=1-q=0.5417.

the element nitrogen has an atomic number of 7 and an atomic mass of 14 how many protons, neutrons and electrons are in a atom o
Nat2105 [25]

Answer: By definition, if  the atomic number  = 7 , then there are 7 protons, 7 electrons, and 8 neutrons!

Explanation:

The atomic number is by definition the number of protons, positively charged particles, contained within the atomic nucleus. So if there are 7 protons, there MUST be 7 electrons, 7 negatively charged particles. Why? Because matter is electrically neutral, and positive and negative particles must be equal.

Electrons have negligible mass; the mass number depends on the number of protons contained within the nucleus, PLUS the number of neutrons. Given that we have  15  N , there must be 8 neutrons contained within the nucleus.  does this help?
