Due to natural selection , if the predator of the gazelle declines, then the prey the gazelles will increase since there isn't many cheetahs killing them anymore.
the second should be competition, since there will be more gazelles needing to eat.

Explanation:
DNA is composed of smaller subunits called nucleotides.
Structure of a nucleotide contains a 5-carbon sugar (Deoxyribose), phosphate group and one of the four nitrogenous bases.
Adenine and Thymine are nitrogenous bases found in DNA. Other nitrogenous bases are cytosine, guanine and uracil.
Adenine, Thymine, Guanine and Cytosine are found in DNA whereas in RNA, Uracil is present instead of Thymine.
DNA is a double stranded structure.
In DNA, adenine of one strand always pairs with thymine of the other strand (complementary). Similarly, guanine of one strand pairs with cytosine of complementary strand. Adenine pairs with Thymine via 2 hydrogen bonds whereas cytosine pairs with guanine via 3 hydrogen bonds. This hydrogen bonding maintains the double helix structure of DNA.
It is implied that for every thymine present in DNA there will be adenine on the complementary stand with which it will bind via 2 hydrogen bonds.
So if a double stranded DNA sample contains 10% Thymine, then it will also contain 10% adenine. This makes the combined contribution of adenine and thymine to be 20%. The left over 80% of DNA will contain equal amounts of cytosine and guanine as each guanine binds with cytosine via 3 hydrogen bonds. So if we divide 80% into 2 equal parts then it is 40%. Hence, there is 40% guanine, 40% cytosine, 10% adenine and 10% thymine.
If a mutation occurs in the DNA let's say a point mutation only one of the base pairs will be different. The codon will be different so a different amino acid will be synthesized. Amino acids have different radicals with different functional group. Those radicals that differ from amino acid to amino acid determine the shape and function of the protein. Therefore a mutated gene will cause the synthesis of a protein with an altered shape and function. A good example is sickle cell disease. Where glutamic acid is replaced with valine and the beta chain of hemoglobin has a deformed shape and has an altered function(carries less oxygen).
Answer:
There is no short answer.
Explanation:
The T-bone steak is sold at $2.20 per pound with a $0.85 profit for each which means the cost of the T-bone is $1.35 per pound.
If the company decides to cut the T-bone steaks into filet mignons and New York cuts, they get a 6 ounce filet mignon which is 0.375 pound, and an 8 ounce New York cut which is 0.5 pound.
The filet mignon is sold for $4.40 per pound which means that for a 6 ounce piece the company will get $1.65. The New York cut is sold for $3.50 per pound which means that for an 8 ounce piece, the company will get $1.75.
The cost of the T-bone ($1.35) and the processing cost $0.20, the total cost of the final pieces of filet mignon and New York cuts to the company are in total $1.55. The company gets $3.40 by selling the two pieces seperately. This brings their profit to $1.85 which is $0.50 higher than the profit they get from selling the T-bone.
