Sunlight. Based on the sunlight you receive you have three zones.
1. Sunlight zone- There is enough sunlight here and photosynthesis can happen. More than 90% of marine animals live in this zone.
2. Twilight zone- A small amount of light is here and no plants grow here. The fish who live here are the ones who have adapted to the little light. Lantern fish is an example.
3. Midnight Zone- 90% of the ocean is in this group. It is entirely dark and the temperature is  freezing.

If you were to repeat the Meselson Stahl experiments, but rather than use N15 and N14, you use P32 and P31, how would the result
bonufazy [111]

Answer:

The correct answer will be option-C

Explanation:

The CsCl gradient centrifugation in Meselson Stahl experiments is done to separate the bands of the DNA containing isotopes on the basis of difference in the density.

In the experiment, bacterial cultures were grown in the medium of 15N and 14N but if we repeat the experiment with P32 and P31 instead of 15N and 14N and centrifugation is performed then the banding pattern will be the same as of the previous experiment as the method of the replication is same that is semi-conservative.

Thus, Option-C is the correct answer.

Scorpion cells undergo aerobic respiration, during aerobic respiration oxygen is used, and ATP is created.

During aerobic cellular respiration, glucose is absorbed with oxygen to form ATP, which can be used by cells. Carbon dioxide and air are formed as by-products. The overall extension to aerobic cellular respiration is: During cellular respiration, glucose and oxygen form ATP.

This process takes place in the mitochondria. So respiration occurs in animals and plants because both have mitochondria.

Aerobic respiration is respiration that requires oxygen while anaerobic respiration is respiration that does not require oxygen. Aerobic respiration consists of several stages, namely: glycolysis, oxidative decarboxylation, Krebs cycle, and the electron transport chain which have been discussed in the previous material.

Cyclin-dependent kinases (Cdks) are enzymes involved with the control of mitosis; Drs. Lee Hartwell and Paul Nurse won the Nobel
Deffense [45]

Answer:

Option C

Explanation:

Dr. Leland Hartwell used baker’s yeast, <em>Saccharomyces cerevisiae</em>, as a model system, which was a highly suitable model for cell cycle studies. He introduced the concept of Checkpoints where he said cells are arrested if damaged so that the cells repair system can work to correct such damages. Dr. Paul Nurse used a different type of yeast, <em>Schizosaccharomyces pombe</em>, a type of yeast distantly related to the baker's yeast as a model organism.
