All of these statements are incorrect EXCEPT: _______________
a. Right atrioventricular valve prevents the backflow of blood into the left ventricle when the ventricles relax.
b. Left atrioventricular valve prevents the backflow of blood into the left ventricle when the ventricles relax.
c. Aortic semilunar valve prevents the backflow of blood into the left ventricle when the ventricles relax
d. Pulmonary semilunar valve prevents the backflow of blood into the left ventricle when the ventricles relax
Answer: C
Explanation:
All of these statements are incorrect except Aortic semi lunar valve prevents the back flow of blood into the left ventricle when the ventricles relax. Thus, option C is correct.
What is the function of semi lunar valves?
The main function of semi lunar valves is that it allowed the blood to be pumped into the major arteries while preventing the back flow of blood from the arteries into the ventricles. The semi lunar valves allow blood to be pumped into the major arteries while preventing back flow of blood from the arteries into the ventricles.
The semi lunar valves has been located at the connections between the pulmonary artery and the right ventricle, and the aorta and the left ventricle. These valves has been allowed the blood to be pumped forward into the arteries, but prevent back flow of blood from the arteries into the ventricles. These valves do not have sub valvular apparatus and are more similar to the semi lunar valves in veins and lymphatic vessels than to atrioventricular.
Therefore, All of these statements are incorrect except Aortic semi lunar valve prevents the back flow of blood into the left ventricle when the ventricles relax. Thus, option C is correct.

What parts of our bodies are made up only of muscles?
Why is DNA a suitable molecule for information storage?
What is the function of genes in the DNA molecule?
Answer both these questions in a paragraph each (5 -1 0 sentences)
Answer:
#1 = DNA rather than RNA carries the hereditary genetic code in all biological life on Earth. DNA is both more resilient and more easily repaired than RNA. As a result, DNA serves as a more stable carrier of the genetic information that is essential to survival and reproduction. First, information stored in the DNA molecule must be copied, with minimal errors, every time a cell divides. This ensures that both daughter cells inherit the complete set of genetic information from the parent cell. Second, the information stored in the DNA molecule must be translated, or expressed.
#2 =They give instructions for a living being to make molecules called proteins. These instructions are stored inside each of your cells, distributed among 46 long structures called chromosomes. These chromosomes are made up of thousands of shorter segments of DNA, called genes. They give instructions for a living being to make molecules called proteins. Each gene stores the directions for making protein fragments, whole proteins, or multiple specific proteins.

An automobile with a mass of 1200 Kg accelerates at a rate of 3 m / s2 in the forward direction. What is the net force acting on the automobile? ( Hint: Solve the acceleration formula for force. )
Answer:
3600 N
Explanation:
Force = Mass × Acceleration
= 1200 × 3
= 3600 N
I hope this helps
An automobile with a mass of 1200 Kg accelerates at a rate of 3 m / s2 in the forward direction. The net force acting on the automobile is 3600 N.
What is force?The push or pull on a mass-containing item changes its velocity. An external force is an agent that has the power to alter the resting or moving condition of a body. It has a direction and a magnitude. Force is calculated by multiplying the mass by acceleration.
The product of the molar mass of the compound and the moles of the substance are defined as mass
Here, the automobile has some mass and acceleration. And the force that is acting on the automobile is to be calculated.
Given, the mass is 1200 Kg
The time is 3 m/s2
Force = Mass × Acceleration
1200 × 3 = 3600 N
Therefore, the net force acting on the automobile is 3600 N.

While working on a group project for school, a student asked his group member to check his model of a section of DNA.
Which feedback would the student receive?
a) The model is accurate because all bases are paired correctly.
b) The model is accurate because it shows all components of each nucleotide.
c) The model is inaccurate because the base pairs are incorrect.
d) The model is inaccurate because it is missing the required bases in DNA.
Answer:
C) The model is inaccurate because the base pairs are incorrect.
Explanation:
By using the acronym Apples (Adenine) in Trees (Thymine), Cars (Cytosine) in Garages (Guanine) (ATCG). C would be the correct answer because the model goes by (CATCTGCA) which would be translated into; Cars (Cytosine) in Apples (Adenine), Trees (Thymine) in Cars (Cytosine), Trees (Thymine) in Garages (Guanine) and Cars (Cytosine) in Apples (Adenine).
