Nerve cells are specialized to transmit chemical signals throughout the body. Some nerve cells in humans can be several feet lon

g. Nerve cells transmit signals by allowing chemicals to enter and exit the cell very quickly. Which organelle helps the most with this process?
A
the chloroplasts because they provide the energy needed to allow chemicals in and out of the cell

B
the cell membrane because it acts as a filter to allow nutrients and chemicals in and out of the cell

C
the cell wall because it provides support and structure for the cell as chemicals are moving in and out

D
the nucleus because the genetic material contains the plans for how the chemicals enter and exit the cell

imagine that you could treat chloroplats with an indiicator dye that turns red in acidic conditions, yellow in neutral ocndition
zmey [24]

The amount of light between points 1 and 2 is adequate for photosynthesis to occur at a faster rate than cellular respiration. Acidic conditions typically imply that the solution has an excessive concentration of H+, which makes the solution acidic. By dividing the reaction into half-reactions, the balancing process begins.

This indicates that more CO2 is being consumed than is being produced, which makes the problem more straightforward.

The signal will become purple as a result, from yellow. After point 2, light levels are low enough that cellular respiration outpaces photosynthesis, which results in more CO2 being generated than being absorbed and raising the pH of the solution. The indication will become yellow as a result, from purple.

An indicator dye called bromothymol blue (BMB) changes color from blue to yellow when acid is present. The pH of the solution decreases when carbon dioxide is introduced because it produces carbonic acid. When the pH is greater than 7.6, green, between 6.7 and 7.6, and yellow, less than 6, BMB is blue.

Many molecules are moved through the body by
Solnce55 [7]

Question: Many molecules are moved through the body by?

Answer:<u> The molecules are moved through the body by uses special transport proteins to move molecules across the membrane that cannot pass thorough on their own. Usually large molecules. Carrier proteins blind and carry the molecules across the cell membrane. They provide an open channel of passageway through the cell membrane for molecules to move across.</u>
