2. Explain why people with poorly controlled diabetes are at risk for amputation

Biology

mestny [16]3 years ago

People with poorly controlled diabetes are at risk of amputation due to damage of nerves in the extremities of the body. This damage to nerves is caused by chronically  high blood sugar. The condition, when it is caused by uncontrolled blood sugar is called diabetic neuropathy.<span>Diabetic neuropathy mostly affects the feet and they lose feeling, such that an affected person cannot  sense pain. When they develop an ulcer or small injury to the feet, it may often go unnoticed and with time become infected.  High blood sugar impairs  the normal healing process and the injury or ulcer may not heal quickly thus compounding the problem. The outcome of this is that the infected part e.g. a toe, may fester and even become gangrenous putting the whole bod at risk and thus the only away to save the rest of the body is removal by amputation.</span>

What happens during mitosiss?
Montano1993 [528]
Oh god, large question. My eyes hurt... Mitosis is the formation of 2 identical daughter cells (cell division). Mitosis have 5 phrases: interphase, prometaphase, prophase, metaphase, anaphase,  telophase and cytokinesis. The chromosomes are duplicated during the cell life just before mitosis since mitosis states that it is the splitting of the cells so duplicating the chromosomes isn't actually mitosis but it is still important to mitosis. Anyway, in interphase, the nucleolus starts to disappear, the microtubule starts to form and the chromosomes start to condense. In pro metaphase, some of the microtubule connect to the centromere, the cell membrane fully disappear and the chromosomes finishes condensing. In metaphase, the chromosomes are pulled to the center of the cell via by the contraction of the spindles and 2 spindles are connected to each of the kinetochores. In anaphase, the chromatids are separated via by the spindles. In Telophase, the nuclear membrane reappears, the chromosomes un-condenses and the micro tubal breaks down. In Cytokinesis, the cell membrane in one cell breaks apart from the other cell forming 2 daughter cells or in plant cells, another cell wall is formed. (this process can differ fro each different organism)

Which hormone is involved in regulating blood sugar levels?
liraira [26]
I think it’s insulin becaus Without insulin, glucose may be present in the blood but the cells are unable to utilize it. People with diabetes lack an adequate supply of insulin

After arousal by a sensory stimulus, consciousness can be maintained by positive feedback, because of activity in the
KIM [24]

Answer:

This question lacks options, options are:

A) cerebral cortex.

B) basal nuclei.

C) sensory pathways.

D) motor pathways.

E) All of the answers are correct.

The correct answer is E.

Explanation:

The cerebral cortex processes and filters its information before passing the most relevant aspects to other regions of the brain. Some of these brain regions, in turn, send information back to the cortex. These loops, known as 'feedback systems', are considered essential for the functioning of cortical networks and their adaptation to new sensory information. Neural circuits must first assess the importance of incoming sensory information and then refine how it is processed in the future. Positive feedback, triggered with the purpose of amplifying the response to the initial stimulus, can be compared to a chain reaction or a vicious circle. Few are the functions regulated by this mechanism; rather it is triggered in pathological situations. It is the system by means of which the organism very rarely regulates any of the bodily functions under normal conditions, making the initial stimulus to be maintained and even increased. This type of mechanism is predominantly present in pathological situations: Its constitutive elements are: stimulus, receptor, afferent pathway, integrating center, efferent pathway, effector and response. The response does not have the ability to satisfy the initial stimulus.

Which of the following best describes a carbohydrate?
Usimov [2.4K]

The correct answer is:

C) Carbohydrates are organic macro molecules that are made up of carbon, hydrogen, and oxygen atoms and are used for energy storage or as structural molecules.


They are commonly found in things such as pasta, sweets, or anything similar, and give a lot of energy that gets quickly burned.


Explanation:

In food science and in several informal contexts, the term "carbohydrate" usually means that any food that's significantly wealthy within the advanced macro molecule starch (such as cereals, bread and pasta) or straightforward carbohydrates, like sugar (found in candy, jams, and desserts)
