Answer:
In the light-independent reactions or Calvin cycle, the energized electrons from the light-dependent reactions provide the energy to form carbohydrates from carbon dioxide molecules. The light-independent reactions are sometimes called the Calvin cycle because of the cyclical nature of the process.

C
Explanation:
When examining the trends in coastal position over a time frame, you perform shoreline change analysis. In most cases, coastal changes are very non-linear.A normal regression of the shoreline happens when there is supply of sediments where the base level is rising at the shoreline.Here the rate of sediment deposition is more than that at which the base level is rising at the shoreline.
The movement ofa shoreline seawards due to sedimentation at the coast is called regression.If this movement is due to sea-level fall like in our case in the question it is force regression.In option C, the sea level is falling.
Explanation:
The resting membrane potential is negative due to the buildup of more sodium ions outside the cell than potassium inside.
Potassium ions readily diffuse out of the cell more quickly than sodium due to the presence of more channels which allow for potassium leakage. The sodium pumps in neuronal membranes bring more K+ ions into the cell; with every three sodium ions pumped out two potassium ions are brought in- this is in order to maintain the negatively charged membranes within the cell along with the resting potential.
Further Explanation:
Neurons have unique structures which aid in facilitating communication by sending and receiving electrical signals very efficient. Parts of a neuron are separated into the
dendrites which receive messages from other neurons allowing them to pass and some of the cell body which contains typical cell components like the nucleus, endoplasmic reticulum and mitochondria.
The axon is an insulated (by the myelin sheath) tubular structure which acts as a bridge to price impulses to other neurons these also contain axon hillocks which are junctions between the axon and cell body
Synapses are junctions where axons connect to dendrites of other neurons at these junctions chemical reactions occur in order to facilitate the passage of information as chemical signals.
There are several neuron types which include sensory motor and into neurons which bridge the two.
- The refractory period describes a period between the initiation of an action potential where Na+ channels are closed, and immediately after the action potential’s peak. Action potentials would require an influx of more positively charged ions; these must be more than a specific threshold in order to have the cells send along more action potentials which helps with figuring out stimulus intensity.
- Potassium ions readily diffuse out of the cell more quickly than sodium due to the presence of more channels which allow for potassium leakage. The sodium pumps in neuronal membranes bring more Na+ than K+ ions into the cell; with every three sodium ions pumped out two potassium ions are brought in- this is in order to maintain the negatively charged membranes within the cell along with the resting potential

Answer:
D
Explanation:
Animals and plants preform a process known as cellular respiration.
This process is:
oxygen+glucose--> carbon dioxide+ water + ATP (energy)
If a plant was placed in this container with carbon dioxide and oxygen, it would preform cellular respiration, but it would also use another process called photosynthesis:
carbon dioxide+water+light energy-->oxygen+glucose
Since a plant performs both, the levels of carbon dioxide and oxygen wouldn't change a lot.
However, if this was an animal, the carbon dioxide levels would increase. An animal would inhale oxygen, use it in cellular respiration, and then exhale carbon dioxide as a waste product.
Therefore, the correct answer is D: increase in carbon dioxide levels.
Explanation:
When blood glucose levels increase above set point, the hormone insulin, which is produced in the beta cells of the Islets of Langerhans in the pancreas, is secreted into the bloodstream. The insulin binds to insulin receptors on cell membranes of liver cells, which results in accelerated conversion of glucose to glycogen, and a slower conversion of glycogen to glucose. This caused blood glucose levels to fall back to normal range again.
