c. Suppose a large population of turtles consists only of two species, snapping turtle and box turtle, but the percentage of the species in the population are unknown. What is the maximum possible value of the diversity index D for the population
Answer:
[tex]D_m=1/2[/tex]
Explanation:
From the question we are told that
2 species
Assuming that questions a and be are solved
Diversity index D=2p_1p_2
with [tex]p_1 +p_2 =1[/tex]
Mathematically
[tex]D=2p_1(1-p_1)[/tex]
[tex]D=2(p_1-p_1^2)[/tex]
[tex]D=2({\frac{1}{4} -(p_1-1/2)^2}[/tex]
Therefore
[tex]D=\frac{1}{2} -2(p_1-1/2)^2[/tex]
Giving
[tex]D_m=1/2[/tex]
[tex]p_1=1/2[/tex]

Mike created the following table... what needs to be corrected
Answer:
The outer core is liquid and the inner core is solid.
Explanation:
This statement is true, the inner core is not liquid it's solid.
The outer core is liquid and the inner core is solid. The opportunity cost of 1 chair is 1/5 table for Mike and 1/3 table for Sandy.
What is cost opportunity?Opportunity cost of the next best option forgone when one alternative is chosen over other alternatives. In order to determine the opportunity cost of making chairs, divide the number of tables made for each person by the number of chairs.
Mike's opportunity cost in making one chair = 4/20 = 1/5
Sandy's opportunity cost in making one chair = 6/18 = 1 / 3
Petrifcation can be defined as the process in which the organic material of the dead living being becomes fossil by the replacement of mineral deposition in the bony, hard material. Thus, although the body components gets decomposed wiped out due to this process. The body shape of the dead organism remains the same as that was in living.
Therefore, The is liquid and the inner core is solid. The opportunity cost of 1 chair is 1/5 table for Mike and 1/3 table for Sandy.

At what points in the progression from gene to protein do these methods act (i.e., what processes do they prevent)
Answer:
Genes are translated, transcribed and after these two steps, the formation of a protein takes place.
DNA is translated, that is, read, in the form of codes and thanks to the machinery of intracellular transcriptases, after this an RNA is encoded that will be made with the assembly of amino acids that together will form proteins.
Proteins can be structural or functional.
Explanation:
There are different methods to intervene in these processes, it can be by means of macromolecules, drugs and also by microbiological factors, that is, by microorganisms such as viruses that take advantage of the human transcription machinery to replicate.

The most infamous outbreak of the plague occurred in the 14th century in Europe, killing an estimated 25 million people, or one-third of the population. The disease is typically spread through the bite of an infected flea, although it can also be transmitted through contact with infected animals or humans.
There are three forms of the plague: bubonic, septicemic, and pneumonic. Bubonic plague is the most common form and causes swollen lymph nodes, fever, chills, and fatigue. Septicemic plague affects the bloodstream and can cause fever, chills, abdominal pain, and vomiting. Pneumonic plague affects the lungs and can cause fever, cough, chest pain, and difficulty breathing.
Today, the plague is rare but still exists in some parts of the world, including Africa and Asia. Early diagnosis and treatment with antibiotics are essential for successful treatment of the disease.

1. A dominant gene (A) causes yellow color in rats, the dominant allele on another independent gene (R) produces black coat color. When the two dominants occur together (A_ R_) they interact to produce gray coat color. Rats of the genotype aa are cream-colored. If a gray male and a yellow female, when mated, produce offspring approximately 3/8 of which are yellow, 3/8 gray and 1/8 cream, and 1/8 black, what are the genotypes of the parents
Answer:
Parents: Yellow (Aarr) and Grey (AaRr)
Explanation:
Given:
allele A = yellow
allele R = black,
Heteroozygous = gray
Genotypes of the parents:
yellow (Aarr) - female
gray (AaRr) - gray
