Humans burn fossil fuels and wood, releasing carbon dioxide into the atmosphere. This carbon dioxide is then absorbed by trees for photosynthesis. These processes are contributory to which chemical cycle?
Carbon cycle controls the amount of carbon dioxide in the atmosphere. These processes are contributory to the carbon cycle in the environment.
What is a carbon cycle ?
The carbon cycle is nature's method of recycling carbon atoms, which repeatedly go from the atmosphere into Earth's living things and back into it. The majority of carbon is preserved in rocks and sediments; the remainder is preserved in the ocean, the atmosphere, and living things.
Life on Earth is reliant on the carbon cycle. The quantity of carbon that is naturally released from reservoirs is equal to the amount that is naturally absorbed by reservoirs because nature tends to maintain carbon levels in balance. This carbon balance must be preserved for the earth to continue to support life.
Therefore, the carbon cycle is an important chemical cycle.

Explanation:
ᴍᴀʀᴋ ᴀs ʙʀᴀɪɴʟɪᴇsᴛ
Answer:
Wind energy is one of the most commonly used types of renewable energy. and also happens to be one of our fastest-growing sources of electricity. However, while there are a number of environmental benefits to using wind energy, there are some downsides. On the pros side, wind is a clean, renewable energy source, and is one of the most cost-effective sources for electricity. On the cons side, wind turbines can be noisy and unappealing aesthetically, and can sometimes adversely impact the physical environment around them. Similar to solar power, wind power is also intermittent, meaning that turbines are reliant on weather and therefore aren’t capable of generating electricity 24/7. Unlike coal, natural gas, or oil, generating electricity from wind doesn’t result in greenhouse gas emissions. While there are some environmental considerations that come with building large wind farms, once operational, wind turbines themselves don’t require burning any fossil fuels to operate.
Additionally, wind energy is completely renewable and will never run out. In opposition to traditional fossil fuels resources that replenish very slowly, wind naturally occurs in our atmosphere, and we don’t have to worry about supply issues in the future.
As far as upfront costs go, wind farms or individual turbines can be expensive to install. However, once up and running, operating costs are relatively low; their fuel (wind) is free, and the turbines don’t require too much maintenance over the course of their lifetime.
A wind turbine’s effectiveness in generating electricity depends on the weather; thus, it can be difficult to predict exactly how much electricity a wind turbine will generate over time. If wind speeds are too low on any given day, the turbine’s rotor won’t spin.
This means wind energy isn’t always available for dispatch in times of peak electricity demand. In order to use wind energy exclusively, wind turbines need to be paired with some sort of energy storage technology.
One of the biggest downsides of wind energy is the noise and visual pollution. Wind turbines can be noisy when operating, as a result of both the mechanical operation and the wind vortex that’s created when the blades are rotating. Additionally, because wind turbines need to be built up high enough to capture a good amount of wind, the turbines can often interrupt otherwise scenic landscapes, such as mountain ranges, lakes, oceans, and more.

What would happen to the food that someone ate if they didnt have the digestive enzymes they needed
Answer:
The digestive system is my favorite system! Without it you would not survive. Our digestive system is how we break down food into nutrients that feed our cells and give us energy to move, talk, grow, think, reproduce, and all the other crazy things that humans do.
Although each of the parts of the digestive system has specific and important functions, shockingly, you can survive without some of the parts. For example, morbidly obese individuals can have their stomach entirely removed in a procedure called a gastric bypass. In this surgery, the small intestine is linked directly to the esophagus thus “bypassing” the stomach. You can also live without your appendix. In fact, it sometimes negatively impacts health as it can become infected (have you ever known someone who had their appendix burst?). The appendix was thought to be a “vestigial organ” meaning that at one point in evolutionary history, we humans had a need for it, but now we don’t; however, there is recent evidence that the appendix is an important hotbed for beneficial bacteria that help us digest food.

The diagrams show what happens to the shape of a plant cell place in distilled water. Explain why the cell swells and becomes turgid. Name the process involved.
Answer:
the name of the process should be osmosis
Explanation: Reason being that plant cells are hypertonic because they have a cell sap so when they are pout in distilled water which is a hypotonic solution, it then absorbs water by osmosis and swells up and become turgid. But they do not burst because they have a cell wall that develops a wall pressure that balances the turgor pressure exerted by turgid cells
20 Points!!!! Answer ASAP!!! Describe the process of oil extraction in complete sentences. Be sure to include information about how the process has changed in recent years.
Oil extraction is the process of recovering crude oil from underground reservoirs, in recent years, the process of oil extraction has changed, with new technologies and techniques allowing for more efficient and cost-effective oil production.
What is oil extraction?
The process of oil extraction involves drilling wells into the earth and then using various techniques to bring the oil to the surface, and the first step in oil extraction is to identify a suitable location for drilling, which is typically done using geologic surveys and other exploration techniques to locate areas with the potential for oil reserves, next step is to complete the well by installing a casing that helps to prevent the well from collapsing. Technologies such as "hydraulic fracturing," which involves injecting water and sand and assisting in the release of trapped oil and gas, have recently gained popularity.
Hence, it is the process of recovering crude oil from underground reservoirs, in recent years, the process of oil extraction has changed, with new technologies and techniques allowing for more efficient and cost-effective oil production.

On the image, which letter represents the enzyme?
Answer:The correct answer is B
Explanation:
I hope this helps you out!
From the image, the letter that represents the enzyme is B.
Enzymes are substances, made up of proteins, which are capable of speeding up the metabolic reactions in the human body.
There is a theory that explains the mechanism of action of enzymes. This is called the enzyme lock and key theory.
This theory states that enzymes bind to substrates temporarily forming enzyme-substrate complex that appears like the fitting of a lock and key.
This simply means that the same way a particular key can only fit into a particular lock is the same way a particular substrate must combine with a particular enzyme for a reaction to occur.
From the diagram,
B represents the enzyme with an active site which must fit into a substrate
A represents the substrate.
Therefore, the the letter that represents the enzyme is B.

Bobcats are generally solitary and establish territories of a certain size where they hunt for food. What type of population dispersion would you expect bobcats to have?
Answer:
Uniform dispersion.
Explanation:
The bobcats' population distribution would be a uniform dispersion because they are distributed in an area in a balanced way. That is to say, that there is space between them and that each bobcat establishes its personal space when hunting and for their daily life. As they are solitary animals, they do not live in groups and only associate with other bobcats to reproduce themselves.
Which of the following stages of photosynthesis involves carbon fixation, reduction reactions, and the ribulose 1,5-bisphosphate regeneration?
photoreduction
light-independent reaction
light-dependent reaction
first stage photosynthesis
Answer:
light-independent reaction
Explanation:
Photosynthesis, which is a unique metabolic process where plants synthesize their food (glucose) in the presence of sunlight, occurs in two stages namely: light dependent stage and light-independent stage.
The light independent stage is also known as dark stage because it does not require light to occur. It occurs in the stroma of the chloroplast where ATP and NADPH are used to fix carbon into the production of glucose. This stage involves three major processes:
- Carbon fixation of CO2
- Reduction reactions of G3P
- Regeneration of ribulose 1,5-bisphosphate (RUBP).
