Compare and contrast type 1 and type 2 diabetes

kondaur [170]

Type 1 diabetes: Its a chronic condition in which the pancreas produces little or no insulin. The symptoms include: increased thirst, frequent urination, hunger, fatigue, and blurred vision. This can be cured if treated propertly.

Type 2 diabetes: A chronic condition that affects the way the body processes blood sugar (glucose). the symptoms are the same as Type 1 but sometimes for type 2 you won't be able to feel any symptoms.

Hope this helped :)

Bees can pollinate all types of flowers.

saul85 [17]

Answer:

Yes,it's clear that bees play a vital role in food production. They are excellent pollinators! Most food crops—including fruits, vegetables, nuts, and seeds—must go through pollination. That's the process of moving tiny pollen cells between plants to help them make seeds.

13. Some flowers are not brightly colored at all, but have a very pungent odor that smells like rotting meat. How do you think t

vladimir2022 [97]

Answer:

They smell this way to attract flies and beetles, which normally lay their eggs in feces and rotting materials. Tempted by the scent, the insects visit the flowers and inadvertently pollinate them before leaving.

to correctly measure the amount of water diffusion occurring when water moved over a selectively permeable membrane, you needed

larisa [96]

There are specific methods to be used when measuring the rate of diffusion over a membrane.

In order to accurately measure the rate of diffusion for water through this permeable membrane you need to account for:

The difference in pressure
The surface area of the membrane
The diffusion barrier

It would be correct to state that the speed at which any movement of water occurs is dependent on the pressure being exerted onto the water. This means that when attempting to calculate the rate of diffusion we need to account for the pressure difference. This pressure will be caused by the osmotic gradient.

You will also need to account for the surface area of the membrane and the diffusion barrier. The <u>surface area </u>of the membrane allows us to understand how much <u>space </u>the water has to be able to move from one side to the other. Meanwhile, the <u>diffusion barrier </u>tells us how much <u>resistance </u>the water will have to overcome when diffusing.

By taking all of these parameters into account, we can then use Fick's law to accurately calculate the rate of diffusion for the water and therefore the amount of water that is diffusing through the membrane.

An ancient Greek physician believed performing lobotomies helped release inner spirits that caused mental illness. Please select

4vir4ik [10]

The right answer is false.

Lobotomy is a brain operation that cuts or alters the white matter of a brain lobe. It is now banned in many countries and is no longer considered a good practice in today's medicine.

The lobotomy was performed in psychosurgery with the aim of interrupting certain neural circuits to treat mental illnesses, schizophrenia, epilepsy and even chronic headaches before declining in the 1950s with the advent of the first neuroleptics.
