Explain why people with poorly controlled diabetes are at risk for amputation.
miv72 [106K]
<span>People with diabetes are at a higher risk of amputation than any other person with a chronic disease. A person with this disease is 15 times more likely to have an amputation than others. It is usually a lower limb on the body that risks amputation. Many people will lose a foot or even both feet,due to the disease. This happens because of nerve damage and poor circulation over having high blood sugar for prolonged periods of time. It is important for people with the disease to visit their doctor on a regular basis. </span>

A group of students is trying to grow a kelp plant in a tank without any others animals. They use a temperature regulation syste
mina [271]

I have read the question several times and I believe "A.The kelp draws nutrients from the water rather than the soil, which it does not have available." would be your answer.

Although it is true that kelp is temperature sensitive, the question states that "They use a temperature regulation system to keep the water temperature at about 12°C." So even with the added addition of sunlight, I think the temperature still stays generally the same. And as long as the temperature is between 5-20 C degrees, the kelp should be okay.

However, kelp does not work the same as most land plants, kelp does not have a root system. It instead has a "holdfast" anchoring system that does not transport nutrients. So how does kelp get nutrients? From the water directly. Since the question says nothing about nutrients in the water, and directly talks about nutrients in the soil, we can assume that their is no nutrients in the water (only in the soil). Making A our answer.

This is a copy/pasted answer from a question I also answered.

masya89 [10]

1. E.coli

2. Intestinal tract

E.coli bacteria are useful to humans when they live in the large intestine of humans. The large intestine is an important digestive structure as it is important for the reabsorption of the nutrients.

The E.coli living in the intestine use the available digested nutrients and synthesises the vitamin B and K which are absorbed and utilised by the human body.

Thus, E.coli and Intestinal tract is correct.
