Answer:
Positive feedback.
Explanation:
An increase in body fluids causes increase in kidney filtration which leads to higher production of urine, this type of feedback is known as positive feedback because when there is increase in the output, this is called positive feedback while on the other hand when there is decrease in the output we called it negative feedback. So we can see that the output of the kidney is higher concentration of urine so we can say that it is a positive feedback.

Which of the following is NOT a function of receptors?
A. Receive hormone signals
B. Receive neurotransmitter signals
C. Receive glucose molecules
D. Identify cells
Answer:
The characteristic that is not a function of the receptors is to receive glucose molecules.
Explanation:
The receptors are structures made up of proteins or glycoproteins whose function is to receive specific signals, which determine intracellular changes and promote an effect or action.
Most of the receptors are located on the surface of the cells, serve for cell recognition and are capable of receiving stimuli from neurotransmitters and hormones.
Glucose is a biomolecule that does not constitute a stimulus or possess a specific receptor and enters the cell with the use of a specific transporter.

differentiate between arteries and veins what is the importance of capillaries in the circulatory system.
Answer:
Arteries-1.Involved in carrying pure, oxygenated blood and nutrient-rich blood.
2.Consists of three distinct layers, which are rigid, thicker and highly muscular.
3.Located deep within the body.
4.Red in colour.
5.Carry blood away from the heart to various parts of the body.
6.High pressure, as the blood flows by the pumping pressure of the heart.
7.Comparatively higher oxygen level.
8.The level of carbon dioxide is low
9.Lumina is narrow
10.Valves are absent
11.Arteries are at a greater risk of certain diseases like angina pectoris, atherosclerosis, etc.
Veins-1.Involved in carrying impure, deoxygenated blood
2.Consists of three distinct layers, which are thin and collapsible.
3.Peripherally located closer to the skin.
4.Blue in colour.
5.Carry blood towards the heart from the various parts of the body.
6.Low pressure, as the blood flows by the capillary action of the veins.
7.Comparatively low oxygen level.
8.The level of carbon dioxide is high
9.In upward direction from the body tissues to the heart.
10.Lumina is wide & Valves are present.
11.Veins are less susceptible to diseases such as varicose veins.
Though tiny, the capillaries are one of the most important parts of the circulatory system because it's through them that nutrients and oxygen are delivered to the cells. In addition, waste products such as carbon dioxide are also removed by the capillaries.

Do animal cells have a nucleus ?
Answer:
Yes, animal cells do have a nucleus. If you were to look at the cell structure of an animal, you would see that they do indeed have a nucleus, with somewhat small vacuoles and other cell parts that humans and plants have. Animals do not have cell walls or chloroplasts like plants because they don't need those structures to function.

name one of the scientific principles trevor talks about when describing how the yo-yo is physics at work!! ANSWER QUICK
A scientific principle that is used in describing how the yo-yo is physics at work since it possesses energy.
The yo-yo is physics at work since it exhibits different types of force such as the angular movement, frictional force and force of gravity. The gravitational force can be found in the engine of the yo-yo. When the yo-yo is released, gravity pulls it down to the ground.Also, through the angular momentum, the object can keep spinning.
