Answer:
Type II diabetics have normal to elevated levels of insulin. What, then, might be causing their elevated blood glucose levels? B) defective receptors
Explanation:
Type II dabetics is known as the most common type in adults. In this type, people have normal to elevated levels of insulin. It is related to some other pathologies such as obesity, over weight, stress. <em>Type 2 diabetes is due to defective receptors. There is insuline in muscles, liver and fat tissues. This resistence shows the inhability of cells to respond to normal levels of glucose, elevating blood glucose levels.</em>
Answer:Lipids perform three primary biological functions within the body: they serve as structural components of cell membranes, function as energy storehouses, and function as important signaling molecules. The three main types of lipids are triacylglycerols (also called triglycerides), phospholipids, and sterols.
triglycerides- fat
phospholipids- plant and animal cell membrane
sterols- plant and animal cell membrane's microorganism.

1. The genetic material is a good evidence of evolution because it's been conserved through time but with some slight differences.
Another important aspect is the </span><span>mitochondria.</span><span> The mitochondria resulted from a symbiotic relationship

2. specialized cellular modifications:
There are cellular modifications happening in multicellular organisms. That means, they have different types of cells, with different functions and will express different characteristics. For example:
- </span><span>Nerve

dendrites which is important to receive the electrical signal from another neuron, other cells don't have that.
- Sperm cells have a tail ( </span><span><span><span>flagellum) in order to swim through the vagina and no other cell has that.

The most important function of flowers is reproduction. They help in the union of male and female gametes. Flowers provide nectar to certain birds and insects, which in turn help in the transfer of pollen from one flower to the other.
