Answer:

D) It would contain less nitrogen.

Explanation:

In an investigation of the cycling of environmental gases, a  student placed water and bromthymol blue in each of four test  tubes as shown in the diagrams below. No additional items were  placed in tube 1, a snail was placed in tube 2, an aquatic plant  (elodea) was placed in tube 3, and both a snail and an elodea  were placed in tube 4. The tubes were then stoppered and placed  in bright light for 24 hours. The solution in tube 3 changes after 24 hours because it would contain less nitrogen.

The dfferent tubes are shown in the picture that I uploaded.

Neurons have special proteins in their
Ilya [14]

Answer:

The ribosomes on the rough endoplasmic reticulum (RER) most likely produces neuronal special proteins.

Explanation:

Conduction of electrical impulses by action potentials of neurons takes place through controlled flow of charged ions through neuronal membranes. This ion transfer is controlled by specialized neuronal channel proteins which are present in the neuronal cell membrane.  

These channel proteins allow for hydrophillic passage of ions and water molecules across the neuronal membranes.  

Ribosomes that are attached to the RER are involved in protein synthesis. They carry the code for proteins carried by the mRNA and translate into respective protein.

The RER along with some free ribosomes cluster together as Nissl bodies and are mainly involved in neuronal specialized proteins.
