Answer:
Layer A is the crust and Layer B is the mantle.
Genes in DNA or responsible for the traits an organism has. This is caused by Dominant and Recessive Traits. Remember that Genotypes are the genetic letters such as RR, Rr, and rr. Phenotype is physical traits.
Dominant Traits are more likely or always show in the offspring. The Dominant Genotype uses Capital letters such as RR.
Recessive Traits are less likely to show up. Their Genotype use lower case such as rr. Now genotypes of Rr have one dominant trait and one recessive trait. If the dominant trait was black fur and the recessive white fur, the offspring will be black fur because dominant traits overpower the other.
To understand how to know if an organism will have Dominant or Recessive Genes, you have to use something called a Punnet Square. Lets imagine 2 parents both have the genotype Rr. R is Black fur and r is white fur. As you can see from the chart, 3 of 4 boxes have Rr and 1 rr. Since there is a Dominant Trait with a Recessive, they will show a Dominant Phenotype, or Black fur. This has 3/4 chance and a 1/4 chance for white fur in the offspring.

Answer:
Pesticides can contaminate soil, water, turf, and other vegetation. In addition to killing insects or weeds, pesticides can be toxic to a host of other organisms including birds, fish, beneficial insects, and non-target plants.
These three (3) chemical reactions include Hydrolysis, Carbonation, and Oxidation.
• Hydrolysis is a chemical reaction caused by the water in which water responds with the rock and changes the size and chemical arrangement of the minerals that reduces opposition to weathering.
• Carbonation is an involvement of water with carbon dioxide to create carbonic acid. It appears when the rock minerals respond with fragile carbonic acid made when water associates with carbon dioxide in the air that deeds on the rock by breaching and disbanding the mineral substances.
• Oxidation is recognized as rusting, a procedure whereby the rock minerals misplace one or more ions or atoms in the occurrence of oxygen. Once minerals in the rock rust it will develop less opposition to weathering. The oxygen associates with other constituents via oxidation method given that rise to ion or atom lose.
Answer:
Yes, Since the interphase cells in G2 would have twice the DNA as the interphase cells in G1 phase or start of S phase.
Explanation:
Interphase has three stages: G1, S and G2 phase. DNA replication occurs in the S phase and doubles the DNA content of the cell. So, the DNA content of the interphase cells of the same tissue depends on stages of interphase.
The interphase cells which are in the G1 phase has half the DNA content as it is present in the interphase that has entered the G2 phase after completion of DNA replication in S phase.
