Rainforests around the world are being cleared at an alarming rate to make room for new communities, agriculture, mining, and roads, and to provide lumber for construction and furniture. How might the destruction of rainforests affect the balance of gases in Earth's atmosphere?
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 is a job of the skeletal system?
exchange oxygen and carbon dioxide
deliver nutrients to the body
remove waste
protect organs
Answer:
The answer is that a job of the skeletal system is to protect organs. Hope this helps! :)
Explanation:
The job of the skeletal system is to protect organs, provide support for the body, facilitate movement, produce blood cells, and store and release minerals and fat.
What is the function of a skeletal system?The skeletal system is the framework of the body, consisting of bones, cartilage, and other connective tissues. It provides a strong and stable structure for the body and protects vital organs such as the brain, heart, and lungs. The skeletal system also enables movement, as it works with muscles to allow for locomotion and other bodily functions. Additionally, the skeletal system produces blood cells, stores minerals, and helps regulate the body's pH balance.
The skeletal system provides the body with structural support, and protection of internal organs, and helps in movement by serving as a site for muscle attachment. It also functions in producing blood cells, storing minerals such as calcium and phosphorus, and facilitating communication between different parts of the body through hormones.
Therefore, the correct answer is C) to protect organs.

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.
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.
Using the photosynthesis equation, predict how the rate of photosynthesis might change with variation in the following parameters (assuming that the plants is not receiving the maximum amount it can use):
a. The amount of light hitting a leaf
b. The availability of water
c. The amount of carbon dioxide in the atmosphere
d. The air temperature when water is limiting factor
Answer:
the answer is below
Explanation:
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.

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)?
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

Explanation:
how does atp provide the energy cells need
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.Learn more at: https://brainly.com/question/20263891?referrer=searchResults
