Multiple soil horizons make up a soil profile. Soil horizons are distinguishable regions of soil. They run parallel to the surface and have different characteristics. The soil horizons include the A horizon, E horizon, B horizon and C horizons.
The soil profile is a vertical cross section showing these horizons.
Answer:
a toxin or other foreign substance which induces an immune response in the body, especially the production of antibodies.
Explanation:
1. Both objects have mass and therefore have a gravitational force.
2. Lower mass objects have less gravitational force.
3. Higher mass objects have stronger gravitational force.
Explanation:
To solve this problem, we need a recap of the newton's law of universal gravitation:
The law states that "the gravitational force of attraction between two object is directly proportional to the product of their masses and inversely proportional to the square of the distances between them."
F = ![\frac{G[tex]m_{1} m_{2}](https://tex.z-dn.net/?f=%5Cfrac%7BG%5Btex%5Dm_%7B1%7D%20m_%7B2%7D)
}{
}[/tex]
G = universal gravitational constant
m₁ = mass of object 1
m₂ = mass of object 2
r² = distances between the two masses
From this we can infer that, for gravitational force to exists, both objects must have mass.
Since mass is directly proportional the gravitational force, the lower the mass the less the gravitational force and the higher the mass the stronger the gravitational force.

Answer:
The sequence from least damaging to most damaging is silent, missense, frameshift, and nonsense mutation.
Explanation:
A silent mutation refers to a modification in the sequence of nucleotide bases that constitutes DNA, however, it does not result in a substantial change in the amino acid or in the function of the entire protein. In missense mutation, one DNA nucleotide gets switched out with another one in a manner, which modifies the specified amino acid.
When a missense mutation takes place in the molecule of DNA, it changes one of the sequences of RNA codon produced at the time of transcription. A frameshift mutation refers to a specific kind of mutation, which comprise either deletion or insertion of the additional bases of DNA. Following the mutation, the entire sequence of DNA will be read incorrectly.
A nonsense mutation refers to a genetic mutation in the sequence of DNA, which leads to the formation of the shorter or unfinished protein product. This mutation takes place when an undeveloped nonsense or stop codon gets presented in the sequence of DNA.
Thus, the silent mutation is the least damaging as it does not exhibit any influence on the function or composition of the protein. While nonsense mutation shows the most damaging effect as it results in an abrupt termination peptide chain.
