Answer:
A checkpoint is one of several points in the eukaryotic cell cycle at which the progression of a cell to the next stage in the cycle can be halted until conditions are favorable. ... The G2 checkpoint ensures all of the chromosomes have been replicated and that the replicated DNA is not damaged before cell enters mitosis.
A mutation in a tumor suppressor gene may stop a cell from checking things during the cell cycle.
Tumor suppressor genes are normally expressed genes that control the progression of a cell through the cell cycle.These genes (tumor suppressor genes) act to repair mutations that occurred during DNA replication, slow down cell division, activate programmed cell death pathways (i.e., apoptotic pathways, etc).For example, p53 is a tumor suppressor gene capable of controlling cell division rate by keeping cells from proliferating in an uncontrolled manner.In consequence, mutations of the p53 gene are often observed in cancer cells that lost their ability to regulate the rate at which they grow.In conclusion, a mutation in a tumor suppressor gene may stop a cell from checking things during the cell cycle.

Describe how the life cycles of the grunion and the horseshoe crab are timed to the rhythm of the tides?
Answer:
Grunion (Leuresthes tenuis): life begins at high tide. During summer and spring, thousands of these fish swim up onto sandy beaches (carried in by high tide). This is called a grunion run, and it occurs ta night during the new moon and full moon when the tide is highest. The females wiggle into the sand and lay thousands of eggs as the males deposit sperm around them. Afterward, they are swept back into the sea. The spawning is timed so exactly that it occurs only on the second, third, and fourth days that follow a new or full moon. After the grunion eggs are fertilized, they incubate for two weeks until the next new or full moon occurs.
Horseshoe Crab (Limulus polyphemus): during late May and early June, vast numbers of horseshoe crabs come together in shallow bays, marshes, and inlets along the Atlantic and Gulf coasts, waiting to come up on the beaches to spawn. The signal to begin is provided by the moon. During the new and full moons, when tide is highest, the crabs come ashore. The female produces a cluster of tiny eggs on her abdomen, and the eggs are fertilized by the male's sperm, and then deposited out in the sand by the female. The next two weeks, the eggs incubate until they hatch during the next full or new moon. When the high water reaches the eggs, they hatch and go out into the ocean.

Explanation:
Which statement best describes the movement of ocean waves? Water moves across the ocean's surface water remains in the same place as wave (energy) travels through it water moves because there is a difference in density of the water creating a wave none of these
Answer:
water remains in the same place as wave (energy) travels through it
Explanation:
Winds influence the ocean and its movements. Air current running on the ocean surface transfers energy to water. A wave is nothing else than energy. When the winds provide energy to the water surface and produce waves, it occurs a particular water molecules´ motion. They move in circles from up to down, up to a certain depth, and go back to the surface. And they do so while energy from the wave is passing through. Waves are the ones that move through the ocean until they reach the shore, where the energy is transferred to land. Water molecules remain in the same general area, while energy travels from molecule to molecule as a wave.
Which organisms are secondary consumers in this food web? Select all that apply
Rockskipper, Pufferfish and Peacock Flounder are secondary consumers in this food web. So, the correct options are A, B and C.
What is Food web?A food web is a diagram that shows what is eaten with what in an ecological context and how food chains naturally connect to one another. Consumer-resource system is another term for the food web.
A food web is a comprehensive account of the species that make up an ecosystem and their interactions with one another. It demonstrates how energy is moved along food chains that are connected to other food chains.
After primary consumers, who are primarily herbivores, are omnivores, carnivores, and secondary and tertiary consumers. The apex predators are those animals that have no other predators save humans. They are at the highest point in the food chain.
Therefore, the correct options are A, B and C.

Answer:
meiosis
Explanation:
At high altitudes, air is less dense than at sea level because of decreased air pressure. This means that a person who ascends to high altitudes takes in fewer oxygen molecules per breath. Describe and explain an immediate response that occurs in the circulatory system when a person first reaches high altitudes. Use vocabulary from class.
An immediate response that occurs in the circulatory system when a person first reaches high altitudes is that the heart beats faster to meet the demand for oxygen that the body needs.
What are the main effects of altitude?The higher it is, the worse the symptoms, which include
headacheshortness of breathrapid heartbeatamong othersNot everyone has these symptoms when they go to high-altitude places, but it is also not possible to know who will or will not feel something.
With this information, we can conclude that An immediate response that occurs in the circulatory system when a person first reaches high altitudes is that the heart beats faster to meet the demand for oxygen that the body needs.

Answer:
10. chlorophyll
11. There are two main stages of photosynthesis: the light-dependent reactions and the Calvin cycle.
12. Nutrition is necessary for the growth of new cells and the replacement or repair of worn-out cells. Nutrition gives energy for different metabolic processes in the body. Nutrition is required to produce resistance against different diseases.
13. trypsin
14. salivary amylase
15. Hydrochloric acid helps your body to break down, digest, and absorb nutrients such as protein. The hydrochloric acid found in the stomach facilitates digestion by disintegrating complex large food molecules into simpler molecules. The acid activates the pepsinogen enzyme required to digest proteins.
16. Saliva, the watery liquid produced by glands located under the tongue, is an essential component of the digestive process. Saliva is 98% water, so it moistens the mouth and helps compact food into softened particles for easier swallowing.
17. Digestive enzymes play a key role in breaking down the food you eat. These proteins speed up chemical reactions that turn nutrients into substances that your digestive tract can absorb. Your saliva has digestive enzymes in it. Some of your organs, including your pancreas, gallbladder, and liver, also release them.
