Tumor suppressor genes typically inhibit division of cancer cells and preventing tumor formation.Mutation in this gene result in loss of function so it is typically recessive. This means that tumor suppressor genes acts as brake  in formation of cancer cell. It prevents the growth of tumors. If one brake (one tumor suppressor gene) is defective it can still stop the car or cancer formation. However, since mutation in tumor suppressor gene is recessive, if two brakes are defective the car will not stop. Or the tumor will be expressed and be formed.

A single strand of DNA helix consists of 100 nitrogenous base pairs. On one strand, 36 of the bases are adenine and 24 are cytos
Katena32 [7]
Hello!

For the complementary strand of DNA, 36 Thymine bases and 24 Guanine bases would complete the proper base pairing. 

This is given by the concept of complementarity. A base in DNA has complementarity with only one other base. This complementarity is produced by hydrogen bond interactions.

For DNA, Adenine couples with Thymine and Cytosine couples with Guanine. So the 36 adenine bases will couple with 35 thymine bases, and so on. 

Have a nice day!

The process of diffusion does not require any energy. Why?
Artist 52 [7]

The process of diffusion does not require any energy because the particles move towards equilibrium (option B).

<h3>What is diffusion?</h3>

Diffusion is the movement of fluids (gases) from a region of high concentration toward regions of lower concentration.

Diffusion is termed a passive transport because it does not require energy to occur.

Diffusion as a transport mechanism does not require energy in form of ATP because it moves molecules towards/down a concentration gradient.

Therefore, the process of diffusion does not require any energy because the particles move towards equilibrium.

Why do slow twitch fibers have more mitochondria
Step2247 [10]

Answer:

Slow twitch fibers have more mitochondria because they aerobic oxidation basically oxidative phosphorylation to resist muscle fatigue by generation of ATP molecules.

Explanation:

Slow twitch fibers are also called red muscle fibers that contain large amount of mitochondria and Myoglobin pigment which gives them red coloration.

     Slow twitch  fibers uses oxygen to carry out oxidative phosphorylation of aerobic respiration to generate energy rich compound called adenosine tri phosphate or ATP.Thus the slow twitch muscle fibers can resist muscle fatigue.

      That"s why slow twitch muscle contain more mitochondria
