This question is incomplete because the options are missing; here is the missing section:

How might the destruction of rainforests affect the balance of gases in Earth's atmosphere?

by increasing carbon dioxide and decreasing oxygen

by increasing carbon dioxide and increasing oxygen

by decreasing carbon dioxide and increasing oxygen

by decreasing carbon dioxide and decreasing oxygen

The answer to this question is by increasing carbon dioxide and decreasing oxygen.

Explanation:

Rainforests have a vital role on Earth because these regulate the levels of oxygen vs carbon dioxide. This is because plants including trees, grasses, shrubs, etc. require carbon dioxide as part of the photosynthesis process, and they release oxygen at the end of the process. In this way, rainforests reduce the amount of carbon dioxide and increase oxygen.

In this context, deforestation or the destruction of rainforest for mining, roads, etc. implies there are fewer plants, and therefore, less carbon dioxide is being used and less oxygen is released. This causes an increase in carbon dioxide and a decrease in oxygen.

What are Monosaccharides?

Monosaccharides are the monomers of carbohydrates. It is the energy storage in the body. Carbohydrates provide energy in the form of glucose.

A monosaccharide is a type of simple sugar that serves as the foundation for more complex sugars like polysaccharides and oligosaccharides. Fructose, glucose, and ribose are some examples.

Monosaccharide is an etymology term that means "one saccharide." Saccharides are the basic building blocks of carbohydrates.

Therefore, Monosaccharides are used to store energy. monosaccharides are the monomers of carbohydrates.

Most mutations that cause cancer occur within body cells, and body cell mutations are not inherited. If cancer is not inherited, why does cancer statically appear to run in families?

Family members have a similar genetic make-up that may make them predisposed to cancer.
Family members are exposed to similar environmental conditions.
Family members have a widely varied genetic make-up that can be affected by specific mutagens.
Family members share the contagious mutagens that can be passed by close exposure.

Answers

Answer:

Family members have a similar genetic make-up that may make them predisposed to cancer.

Explanation:

Variation in certain genes can increase the risk of developing certain cancers. This is why certain cancers run in families. There are lots of examples where the risk factor is small, but in some cases, the risk factor is very large.

For example, mutations in BRCA1 are very highly linked to the risk of breast cancer. As a result, many women with mutations in this gene opt to get a mastectomy to reduce their chances of developing breast cancer.

Why does a carrot in a hypertonic solution of salt water float compared to a carrot in a hypotonic solution of salt water (which sinks)?

Answers

Answer:

Cell membranes are permeable to water, and in the absence of a solute on either side of a membrane, water will move one way as easily as it moves the other. If the outside of the membrane contains a solute, such as salt, the solution correspondingly contains fewer water molecules. To restore equilibrium -- the same number of water molecules on both sides of the membrane -- water flows from inside, and the cell shrinks. On the other hand, if the concentration of solute inside the membrane is greater, water flows into the cell and swells it. This is called osmosis.The turgidity, or stiffness, of a carrot depends on the water content of its cells. When the cells are full of water, they grow large and are packed closely together, making the carrot turgid. Conversely, when the cells lose water, they shrink and the carrot shrivels. That's what happens when you put a carrot in salty water and leave it there. When the concentration of water molecules inside the cells matches that outside, the carrot stops shriveling, and when you remove it from the water and taste it, it has a stronger flavor because it contains less water

how does atp provide the energy cells need

Answers

Answer:

Adenosine triphosphate (ATP), energy-carrying molecule found in the cells of all living things. ATP captures chemical energy obtained from the breakdown of food molecules and releases it to fuel other cellular processes.In a process called cellular respiration, chemical energy in food is converted into chemical energy that the cell can use, and stores it in molecules of ATP. When the cell needs energy to do work, ATP loses its 3rd phosphate group, releasing energy stored in the bond that the cell can use to do work.

ATP provides the energy required by cells by releasing a phosphate group.

ADENOSINE TRIPHOSPHATE (ATP):

Adenosine triphosphate (ATP) is a biological molecule that stores and releases energy for living cells.

Structurally, ATP is made up of three components namely: phosphate group, adenine base and ribose sugar.

ATP stores energy when a phosphate group is added to an ADP molecule while it releases energy when a phosphate group is released from the ATP molecule to form ADP and inorganic phosphorus (Pi).

Therefore, ATP provides the energy required by cells by releasing a phosphate group.

a) A plant process that changes sunlight into chemical energy. If there is less light the plant wont be able to function properly

b) Without enough water in the cells, the plants droop, so water helps a plant to stand. Water gives plants moisture to keep them alive.

c) If there is not enough CO2 the plant wont be able to photosynthesise as fastly as it usually does.

d) If the temperature is high and there is lack of water the plant is most likely to die. This is because it will be dehydrated.
