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.

What color would the bby and water turn with plants in the dark
Answer:
The water is drawn in the xylem through capillary action and is dispersed through out the entire plant from stem to tips of the leaves and petals.

What is the function of erythrocytes?
What is the term for all the components of the blood?
What is blood?
Answer:
1. The main physiological role of red blood cells (RBCs), or erythrocytes is to transport of gases (O2, CO2) from the lung to the tissues and to maintain systemic acid/base equilibria. In addition, RBCs are well equipped with antioxidant systems, which essentially contribute to their function and integrity.
2. In humans, it includes plasma (the liquid portion), blood cells (which come in both red and white varieties), and cell fragments called platelets. Plasma is the main component of blood and consists mostly of water, with proteins, ions, nutrients, and wastes mixed in.
3.Blood is a body fluid in humans and other animals that delivers necessary substances such as nutrients and oxygen to the cells and transports metabolic waste products away from those same cells.

why is the late Cambrian thought of as the period of the greatest evolutionary change in life forms on earth's history?
Answer:

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.

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.

“How might an energy requirement affect an individual who has a cancerous tumour?”
Answer:
Cellular respiration describes the series of steps that cells use to break down sugar and other chemicals to get the energy we need to function. Energy is stored in the bonds of glucose (like a stretched rubber band), and when glucose is broken down, much of that energy is released. Some of it is captured in a form that can be used to do work in cells - a molecule called adenosine triphosphate or ATP. The energy that is not captured in ATP is usually given off as heat (one of the things that helps us maintain our normal body temperature).

Which structure does the immune system target in type 1 diabetes?
a. beta cells of the pancreas
b. liver cells that release glucose
c. insulin receptors on fat cells
d. red blood cells in the bloodstream
Answer:
The thymus plays an important role in deletion of potentially autoreactive T cells. However, the presence of islet-specific T cells in the circulation of type 1 diabetes patients and healthy subjects indicates that the thymus is not capable of efficiently deleting all autoreactive T cells (Mathis and Benoist 2009).
Explanation:
Answer:
A: beta cells of the pancreas
Explanation:
Type 1 diabetes makes the pancreas produce little to no insulin.
