I found the attached image on the internet related to this question.
The solid arrows represent neuronal communication. The stimulus, the effects, and the flow of information is all done by receptors and synapses that send a signals across the body in order to have effective feedback responses promoting the homeostasis of the organism.

What is the best way to show the lead levels in six contaminated water wells?
Marrrta [24]

Answer:

Option B, Barr graph

Explanation:

A bar graph is used for comparing several items all together based on any certain parameter.  

Here, the lead content is the comparison parameter while the six sample of contaminated water wells acts as different items being compared.  

A line graph is good to show a continous varying data set, while a circle graph is good to represent the component constitution of any major substance and a data table is best to represent a data set with multiple attributes.

Hence, option B is correct

Explain how osmosis will affect animal cells when the cells are placed into and environment with a low water potential compared
matrenka [14]

Answer:

Explanation:

The cytoplasm in animal cells is surrounded by a membrane, which delimits the cell and its surroundings. As opposite from the plant cells, animal cells do not have a cell wall.

<em>Osmosis</em><em> is the process in which a solvent diffuses across a semipermeable membrane</em> (like the cell membrane) <em>from the zone with the lower concentration of solutes to the zone with the higher concentration. </em>That means that water, in this case, will diffuse spontaneously across the cell membrane from the place with more water molecules (usually, the exterior of the cell) to the place which has less water molecules, or is more concentrated (in this case, the cytoplasm). This diffusion will continue until an equilibrium is reached.

If we place an animal cell, which does not have a cell wall, into an environment with a low water potential, <u>the water will flow from the exterior to the interior</u>. If the water potential is very low compared to the one of the cytoplasm, the cell can receive too much water and explode. This process is called cytolysis.
