Answer:

-elastic membranes

Explanation:

The elastic membrane or tissue of the arteries allows the artery to bend and fit. It is important for artery to be elastic, because it transports oxygenated blood pumped from the heart to the tissues (except for pulmonary artery which carries deoxygenated blood) and thus have a blood pressure that is higher than in other parts of the circulatory system.

What is the ultimate source of heat in the process of global warming

nalin [4]

The sun. Greenhouse gases absorb heat better. So the more of these gases, the hotter it gets. However, the earth itself is naturally heating, but it goes too fast for live to adjust to the temperatures.

tatuchka [14]

1. what is the amount of the bolus dose, in both milligrams and milliliters, that you will administer in the first minute?
The doses is 0.9 mg/kg and the weight of the patient is 143 pounds. So, the total doses of drug needed will be:
Total doses= 0.9 mg/kg * 143 pounds * 0.453592 kg/pound= 58.37 mg.

10% of the doses will be given bolus for 1 min, so the amount would be:
Bolus doses= 10%*58.37 mg= 5.837 mg.
In mililiters, it would be: 5.837 mg * 1ml/mg= 5.837 ml.

2. what is the amount of the remaining dose that you will need to administer?
The remaining dose would be 90% of the total dose. You can either calculate it directly or subtract the bolus doses from the total doses.
Remaining doses= total doses- bolus doses= 58.37 mg- 5.837 mg= 52.533mg

Kipish [7]

Answer: A) Dendrites

Explanation:

Cell body. Also known as a soma, the cell body is the neuron's core.

Axon. An axon is a long, tail-like structure which joins the cell body at a specialized junction called the axon hillock.

Dendrites. Dendrites are fibrous roots that branch out from the cell body.

777dan777 [17]

Answer:

I am a basophil.

Further information:

Basophil:

Basophils are a type of white blood cell. Basophils are the smallest common of the granulocytes, representing about 0.5 to 1% of circulating white blood cells. Yet, they are the major type of granulocyte.

Function of basophil:

They are accountable for inflammatory reactions during immune response, as well as in the development of acute and chronic allergic diseases, including anaphylaxis, asthma, atopic dermatitis and hay fever. They also yield compounds those co-ordinate immune responses, including histamine and serotonin that induce inflammation, heparin that stops blood clotting, although there are less than that found in mast cell granules.

Basophils may present in many specific types of inflammatory reactions, specially those that cause allergic symptoms. Basophils have anticoagulant heparin, which prevents blood from clotting too rapidly. They also have the vasodilator histamine, which promotes blood flow to tissues.

Structure of Basophil:

Basophils comprise large cytoplasmic granules which vague the cell nucleus under the microscope when stained. However, when unspotted, the nucleus is visible and it usually has two lobes. The Mast cell which is another granulocyte has very like in appearance and function. Both cell types store histamine, a chemical that is secreted by the cells when inspired. However, they arise from different branches of hematopoiesis, and mast cells usually do not circulate in the blood stream, but instead are located in connective tissue. Similar to all circulating granulocytes, basophils can be carried out of the blood into a tissue when we need it.
