What is the dynamic of type 1 diabetes process concerning cellular disruption and what is its effect on the major body systems?
Please help, will give brainliest
Answers
Explanation:
Type 1 diabetes occurs when some or all of the insulin-producing cells in the pancreas are destroyed. This leaves the patient with little or no insulin. Without insulin, sugar accumulates in the bloodstream rather than entering the cells. As a result, the body cannot use this glucose for energy.
In most people with type 1 diabetes, the body's immune system, which normally fights infection, attacks and destroys the cells in the pancreas that make insulin. As a result, your pancreas stops making insulin. Without insulin, glucose can't get into your cells and your blood glucose rises above normal.18-

why is the late Cambrian thought of as the period of the greatest evolutionary change in life forms on earth's history?
Answers
Answer:
The Cambrian Period marks an important point in the history of life on Earth; it is the time when most of the major groups of animals first appear in the fossil record. This event is sometimes called the "Cambrian Explosion," because of the relatively short time over which this diversity of forms appears.

d. red blood cells in the bloodstream
Answers
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).

Answer:
A: beta cells of the pancreas

Type 1 diabetes makes the pancreas produce little to no insulin.
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?
Answers
It is a circle of life.
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.

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.

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?
Answers
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.
