Dry season because it increases evaporation of water would increase the concentration of salt in the water
I found the missing part of this question.

The answer is it took 200 years more to double the population from 0.50 billion to 1.0 billion people. The year was 1850.
It was in 1925 when the population double again from 1.0 billion to 2.0 billion.
There are many species being poached. Some include:
- Whales
- Sharks
- Turtles
- Tigers
They all have something valuable, causing them to be poached and sold.
Answer: insertion
Crossing over is when homologous* chromosomes exchange genes, resulting in gene combinations.
Deletion is when a base pair is deleted from DNA. Insertion is when a base pair is added to DNA. Both insertion and deletion are serious because every amino acid beginning at the mutation will most likely be incorrect. This will lead to a nonfunctional protein.
Base-pair substitution is a substitution of one base pair for another in DNA. The effects of this may be a silent** point, missense*** point, or nonsense**** point.

<em>*A pair of matching chromosomes. They have the same genes but can have different versions.</em>
<em>**A special case where no amino acids are affected.</em>
<em>***Affects one animo acid. The whole protein structure and function may or may not be disrupted. </em>
<em>****Results in a stop codon that shortens the protein.</em>
He labeled the protein of bacteriophages with radioactive sulfur and their DNA with radioactive phosphorus. The bacteriophages were allowed to infect bacteria.
