Coastal Ocean!

Explanation: It’s important to remember that although the ocean produces at least 50 percent of the oxygen on Earth, roughly the same amount is consumed by marine life. Like animals on land, marine animals use oxygen to breathe, and both plants and animals use oxygen for cellular respiration. Oxygen is also consumed when dead plants and animals decay in the ocean.

This is particularly problematic when algal blooms die and the decomposition process uses oxygen faster than it can be replenished. This can create areas of extremely low oxygen concentrations, or hypoxia. These areas are often called dead zones, because the oxygen levels are too low to support most marine life.

NOAA’s National Centers for Coastal Ocean Science conducts extensive research and forecasting on algal blooms and hypoxia to lessen the harm done to the ocean ecosystem and human environment.

2. What does a cell need in order to live?

CaHeK987 [17]

Answer:

The most important things for a cell are oxygen in order to respire and Glucose, also for respiration. This is used in a process called glycolysis where the cell makes a chemical called ATP which is basically our energy. ... So basically a cell needs lots to stay alive.

Answer:

It would be A: a cell that has double the number of chromosomes as the parent cell

and if for some reason that is wrong then it could possibly be C and just use the same explanation.

Explanation:

This is because Haploid Gametes are the things that are produced during meiosis-which is a type of cell division which reduces the number of chromosomes in a parent diploid cell by half

Does the size of a genome determine how much information it contains quizl;et

Marina86 [1]

The answer to this statement is true. It is because the size the total amount of the DNA that it contains makes up the size of the genome. Therefore, the size of the genome determines the information that it contains such as the DNA.

Which of the following factors might cause checkpoint genes to interrupt cell division? Check all that apply. Neurological signa

Strike441 [17]

Answer:

Neurological signals sent from fear responses in an organism tell the cell to stop. The cell's DNA has been damaged somehow. The cell's DNA was replicated incorrectly.

Explanation:

All the three options given can cause checkpoint genes to interrupt cell division.

Checkpoint genes are transcription genes that control cell cycle and sense defects during cells processes like DNA replication, segregation e.t.c and create response till the defects is repaired in the DNA. The important of checkpoint is that it ensure enough nutrients are available to support for division, ensure that the DNA has not been damaged, ensure that cells DNA is copied correctly and make sure cells have enough RNA for their protein synthesis.

Checkpoints genes can interrupt cell division if the dna is damaged, Dna is copied incorrectly and neurological signal sent from fear responses in an organisms tell the cells to stop.

lilavasa [31]

José probably doesn't feel any pain because his body, during and after exercise released endorphins which are endogenous opioids. This endorphins promote a sense of satisfaction and pleasure, and make pain and discomfort feel irrelevant.
