The Griess test uses chemicals to develop gunpowder residue patterns, particularly around bullet holes.

It is a scientific chemistry test which identifies the proximity of nitrite ion in liquid. One of its most significant applications is obtaining nitrite in drinking water. The test has also been extensively applied for the exposure of trace explosives comprising nitro groups. It is essential to release the nitrate ion from the nuclear explosive before the examination. This is commonly done by alkaline hydrolysis.

Which of the following would not be facilitated diffusion?
marusya05 [52]

Answer:

A. A water molecule passes through a semi permeable membrane

Explanation:

Facilitated diffusion is the diffusion of a molecule without any assistance from a protein or protein channel.

In facilitated diffusion, a molecule will diffuse by itself through a semi permeable membrane, such as the cell membrane.

Answer choices B, C, and D are incorrect because they are all examples of facilitated diffusion. The molecules required assistance from a protein.

Answer choice A is correct because the water molecule was able to pass through by itself.

So, the correct answer is A. A water molecule passes through a semi permeable membrane

Marat540 [252]

Answer:

Sympathetic division is responsible for the nervousness, pounding in the chest and the butterfly movement in the stomach while parasympathetic division overest a and digest the nervousness.

Explanation:

The nervousness experienced when someone is about to speak in front of a class is caused by the sympathetic system which have divergent effects as many different effector organs are activated together for that same purpose. I.e More oxygen are inhaled and delivered to skeletal muscle. The respiratory, cardiovascular, and musculoskeletal systems are all activated at the same time causing an unstable reaction to the central nervous system...

On the other hand, the parasymthetic division causes the central nervous system to rest and digest at a very slow rate..

At a point in time the central nervous system triggered an Homeostasis action which posses a balance between the two divisions.I.e symthetic and parasymthetic and then brings about a balance to the body reaction at that same point.
