Answers

This is an example of Type 2 diabetes. This condition occurs when our pancreas is unable to produce enough insulin or when the insulin it does produce cannot function correctly which indicates that the blood sugar (glucose) levels are increasing.

What is insulin?

Our pancreas secretes the hormone insulin, which regulates the level of glucose in your bloodstream at any given time. It aids in the storage of glucose in your muscles, fat, and liver. It also controls how proteins, lipids, and carbs are metabolized by your body. Insulin is secreted by the beta cells of the pancreas.

What is diabetes?

It is a medical condition which induces a person's blood sugar level to be too high. There are mainly two types of diabetes namely, Type 1 diabetes and Type 2 diabetes.

What is type 2 diabetes?

When the insulin sensitivity increases and the blood sugar levels rise, type 2 diabetes develops. During insulin resistance, our body is unable to respond to insulin as it should, which prevents it from properly absorbing and using the sugar in meals as fuel. This causes the sugar to remain in our blood, which can eventually result in a chronic illness that, if left untreated and unmanaged, can have a major impact on our health.

There were roughly the same numbers of chloroplasts in every algae cell. The amount of oxygen produced by this region of the algae was roughly inversely proportional to the number of bacteria grouped at each wavelength (colour).

What presumptions did Engelmann make in order to come to the conclusion that red and violet-blue light were better at promoting photosynthesis than green light?

They reflect yellow and red light while absorbing blue-green light. Eating carrots helps your body absorb the carotenoids, which are pigments.
