The Sun. It starts off by evaporating, which is done by the sun heating up the water.
Solvents are dissolved in a solute to create a solution. Some examples are sugar solutions, where sugar is the solvent, water is the solute, and the solution is the sugar water that results, as long as the sugar is dissolved evenly in the water.
Hope this helped!
Answer:
D.
Explanation:
Natural selection is the way that organisms adapt through adaptations to better survive and pass on the special genes which enable the offspring to survive. Saying an organism will always mutate to survive is wrong, as natural selection implies that not all organisms survive. With natural selection, nothing is "selected", so B and C are not correct. However, mutations DO make organisms "more fit" to survive their environments, so D is the answer.
Answer:
Number of chromosomes
Explanation:
Meiosis is a specialized type of cell division in which the gametes are produced.
A diploid parent cell first replicates its DNA. Then, two rounds of cell division occurs to produce 4 haploid cells, each with half the amount of chromosomes. These gametes fuse during fertilization to restore the diploid state.
Therefore, meiosis changes the number of chromosomes.
