Which is the most efficient way to avoid DNA mutations from UV radiation?
Avoid getting X-rays at the doctor’s office.
Avoid protective shields during X-rays.
Avoid UV radiation by wearing sunscreen.
Avoid UV radiation by using a tanning bed.
Answer:
Sunscreen is the best, and most efficient way to avoid DNA mutations. UV radiation causes thymine dimers in the DNA complex, so limiting UV radiation is key to avoiding DNA mutations.
Explanation:
The most efficient way to avoid DNA mutations from UV radiation is to avoid UV radiation by wearing sunscreen. Thus, the correct option is C.
What is DNA mutation?DNA mutation may be defined as the process that induces sudden, stable, and inheritable changes in the genetic material of organisms through various factors.
The UV radiations are the most potent physical agent that induces DNA mutation. But in order to avoid such kinds of DNA mutations from UV radiation one must be required to be protected from such kinds of harmful radiation with the help of sunscreen.
The UV radiation induces DNA mutations by causing the dimerization of the thymine base, which significantly alters the whole sequence of genetic material.
Therefore, the most efficient way to avoid DNA mutations from UV radiation is to avoid UV radiation by wearing sunscreen. Thus, the correct option is C.

The division of the cytoplasm, which follows Mitosis, is called...
Answer:
Cytokinesis,
Explanation:
Cytokinesis, the division of the cytoplasm to form two new cells, overlaps with the final stages of mitosis. It may start in either anaphase or telophase, depending on the cell, and finishes shortly after telophase.
The division of the cytoplasm, which follows Mitosis, is called Cytokinesis. This is further explained below.
What is Mitosis?Generally, Mitosis is simply defined as a kind of cell division that produces two daughter cells with the same number and type of chromosomes as the parent nucleus, as seen in normal tissue growth.
In conclusion, Cytokinesis is simply defined as the division of the cytoplasm that occurs after mitosis to produce two daughter cells.

How does the structure of DNA explain chargaff's rule?
Answer:
Chargaff's rules state that DNA from any species of any organism should have a 1:1 stoichiometric ratio (base pair rule) of pyrimidine and purine bases and, more specifically, that the amount of guanine should be equal to cytosine and the amount of adenine should be equal to thymine
Chargaff's Rule explains that in the natural DNA, the total number of guanine equals to the number of cytosine and the total number of adenine equals to the number of thymine. This tells about the base pair composition of DNA molecule.
What is Chargaff's rule?Chargaff's rule states that in the DNA molecule of any species or organism, the total amount of guanine residues should be equal to the amount of cytosine residues and the amount of adenine residues should be equal to the amount of thymine residues. A stoichiometric ratio of 1:1 of purine and pyrimidine bases i.e., A + G = T + C should be fulfilled.
Chargaff's rule describes the ratio of the various nitrogenous bases present in the DNA molecule. It aids in the determination of the structure and composition of DNA in living organisms. It is constant for a species.

You want to make 1 ton ration of an 18% protein ration using corn (12%) and soybean meal (22%). How much of each will he have to mix together? Show your work for full credit.
Answer:
To make a 1 ton ration of an 18% protein ration using corn (12%) and soybean meal (22%), 0.6 tons of soybean meal and 0.4 tons of corn are needed
Explanation:
Using the Pearson’s Square calculations:
1. Subtract across the diagonal:
a. 18% - 12% = 6 parts soybean meal
b. 18% - 22% = 4 parts corn
2. Sum the parts:
a. 6 parts soybean meal + 4 parts corn = 10 totalparts
3. Divide each part by the total to calculate the percentage of each feed to include in the ration:
a. 6 parts soybean meal ÷ 10 total parts * 100 = 60.0% soybean meal
b. 4 parts corn ÷ 10 total parts * 100 = 40.0% corn
So, to make 1 ton ration of an 18% protein ration using corn (12%) and soybean meal (22%),
60% of soybean meal is needed = 60/100 * 1 ton = 0.6 tons of soybean meal
40% of corn is needed = 40/100 * 1 ton = 0.4 tons of corn

Because biological systems are generally held at constant temperature and pressure, it is possible to predict the direction of a chemical reaction by measuring which of the following?
a. ATP concentration
b. Enthalpy
c. Entropy
d. Free energy
Because biological systems are typically maintained at constant temperature and pressure, calculating the free energy of a chemical reaction allows one to predict the reaction's direction that is in option d.
What role does free energy play in the biological system?In a biological system, the free energy is very significant, where the free energy is the amount of energy that is needed by the cells of the body to perform the function, and the negative free energy indicates that the reaction is exothermic and this energy can be used for other processes. The process where free energy is needed, known as endothermic process, must be completed when there is positive free energy.
Hence, because biological systems are typically maintained at constant temperature and pressure, calculating the free energy of a chemical reaction allows one to predict the reaction's direction that is in option d.

It made it possible for people to discover and learn about cells.
Explanation:
The cell is the basic unit of structure and function of all living beings. A cell can also be defined as a morphological, functional, and reproductive unit of all living beings.
Every living organism is made up of one or more cells. All cells are created from an existing cell. A cell is the smallest unit that has all the characteristics of life. A set of cells of similar or the same appearance, embryonic origin, and function is called tissue.
The science that studies the cell is called cytology. There are organic and inorganic compounds in the cell. Of the inorganic compounds, water and salts are the most common. Organic compounds in the cell contain carbohydrates, fats, and proteins.
