Populations have genetic variation.
The environment changes.
Organisms must have specific traits in order to survive and reproduce.
Explanation:
Natural selection provides an advantage during an adverse condition for organisms that have a rich genetic variation in their population.
Also, environmental changes induced natural selection whereby organisms must adapt to changes around them.
For organisms to survive, they must have specific traits that gives them a competitive reproductive advantage.
To find the number of neutrons, subtract the number of protons from the mass number. number of neutrons=40−19=21.
Answer:
<h2>0.62 mL</h2>
Explanation:
The volume of a substance when given the density and mass can be found by using the formula
![volume = \frac{mass}{density} \\](https://tex.z-dn.net/?f=volume%20%3D%20%20%5Cfrac%7Bmass%7D%7Bdensity%7D%20%5C%5C)
From the question we have
![volume = \frac{3.50}{5.61} \\ = 0.6238859...](https://tex.z-dn.net/?f=volume%20%3D%20%20%5Cfrac%7B3.50%7D%7B5.61%7D%20%20%5C%5C%20%20%3D%200.6238859...)
We have the final answer as
<h3>0.62 mL</h3>
