Answer:
Type 2 diabetes mellitus generally reflect declining receptor sensitivity to insulin rather than decreased insulin production- True.
Most Type II diabetes do not produce insulin- False.
Explanation:
Diabetes mellitus may be defined as the group of metabolic disorder that re characterized by the high blood glucose levels in the body of an individual.The receptor sensitivity decreases towards insulin decreases in Type II diabetes.
The insulin is produced in the proper amount during Type II diabetes. The receptors are unable to respond towards the diabetes.
Thus, the answer is a)-True
b)-False.
Type 2 diabetes is characterized by insulin resistance and declining insulin receptor sensitivity. Over time, the insulin production may decrease but does not stop entirely.
The statement is partially true. In Type 2 diabetes mellitus, the primary problem is often not a lack of insulin production but rather a decreased sensitivity of body tissues to insulin, a condition known as insulin resistance. As a result, the body needs higher amounts of insulin to lower blood glucose levels. However, over time, the beta cells of the pancreas that produce insulin can become impaired and may produce less insulin, but they don't stop producing insulin altogether as suggested by the statement.

B. an article
C. an epic poem
D. a nonfiction story
The one that doesn't exemplify prose literature would be:
C). An epic poem
In literature, "Prose" is described as the form of writing that is not restricted by metrical structure or construction and aims to communicate an idea or story simply.
The one that doesn't exemplify prose would be 'an epic poem" because it carries a quite formal pattern using the verse form.
Since the verse form is more poetic and hence, it doesn't exemplify 'prose.'
Thus, option C is the correct answer.

Explanation:
To determine the type of microscope used to capture the image of a cell's mitochondrion, you would typically need additional information, such as the features of the microscope and the microscopy technique employed. Microscopes commonly used to visualize cell structures include optical microscopes, electron microscopes, and fluorescence microscopes, each with its own capabilities and applications. If you have more details about the image or the microscope used, I'd be happy to provide further assistance.
Food provides energy to animal cells, whereas sunshine provides energy to plant cells. Chemicalenergy, which is the energy held in the bonds that connect the atoms of every molecule, is used by all cells. Cells must be able to release the chemical energy in the connections in order to continue to function.
The smallest unit in biology that can sustain life on its own and makes up all living things as well as the body's tissues.
After using a very early microscope to examine a piece of cork, Robert Hooke proposed the name "cell" in 1665, derived from the Latin cella, which means "storeroom or chamber."
It is also claimed that he believed the rectangular spaces resembled some monasticcells.
Animal cells get their energy from food, but plant cells get their energy from sunlight. All cells employ chemicalenergy, which is the energy stored in the bonds that bind the atoms of every molecule.
To keep working, cells need to be able to discharge the chemical energy stored in their connections.
Thus, this way, plants and animal cells obtain their energy.

Plant cells obtain their energy by making their own food through the process of photosynthesis. Photosynthesis is a process by which carbon dioxide , water and light energy are utilized by plants to make energy-rich carbohydrates such as glucose. Plants store up the glucose as starch in their tissues. When plant cells needs energy, they simply take glucose molecules from their store of starch and use it in cellular respiration to produce ATP, the form of energy that the cell uses to function.
Animals on the other hand do not make their own food but ingest ready made food and break it down into its simplest units through the process of digestion. Complex carbohydrates are broken down to glucose units. Glucose is directly taken in by the animal cells where it is used in cellular respiration to produce ATP ,which fuels the cell activities.
