Membranous sacs containing substances that were produced in the cell, such as neurotransmitters or hormones, are called VESICLES.
Vesicles are membrane sacks that store different chemical messengers such as neurotransmitters and hormones.For example, neurotransmitter vesicles are specific synaptic vesicles that store neurotransmitters in order to release them at the synaptic cleft.The release of neurotransmitters or hormones by membrane vesicles leads to the activation of the target cell.In conclusion, membranous sacs containing substances that were produced in the cell, such as neurotransmitters or hormones, are called VESICLES.

Our muscle cells sometimes turn to lactic acid fermentation rather than respiration in order to produce energy because they
A.run low on glucose and need something to replace it.
B.produce too much oxygen for our bodies to handle.
C.use up all the pyruvates and must compensate with fermentation.
D.do not receive enough oxygen during strenuous exercise.
Explanation:
D) do not receive enough oxygen during strenuous exercise is right answer.
Muscle cells turn to lactic acid fermentation rather than respiration when they do not receive enough oxygen during strenuous exercise. Thus, the correct option is D.
What is Lactic acid fermentation?Lactic acid fermentation is a metabolic process in which glucose and other sugars are converted into the cellular energy (ATP) and lactic acid. It is a form of anaerobic fermentation reaction which occurs in some of the bacterial cells and animal cells, like muscle cells.
When the muscles are contracting very quickly during strenuous exercise, the oxygen cannot travel fast enough to the muscle cells to keep up with the need of ATP in the muscles. At this point, the muscle fibers switches to a breakdown process which does not require much oxygen (anaerobic respiration).
The muscle cells produce ATP with the lactic acid to give you energy during these difficult physical activities. This condition results when there is not enough oxygen in the body to produce ATP, so the lactic acid fermentation provides acts as a substitute to get ATP without oxygen.
Therefore, the correct option is D.

4 Spheres Observation (Bio, Geo, Atmo, Hydro) : What did you see that represents each? How did they interact with each other? and pls be specific in ur answer, and pls no links!
Answer:
The spheres interact to effect Earth’s systems and processes, and they are constantly changing each other.
For example, ocean currents (hydrosphere) affect air temperature (atmosphere): The Gulf Stream is a powerful water current in the Atlantic Ocean. It’s warm water moderates the temperatures on the east coast of the USA.
Another example of how the spheres affect each other is through erosion. Erosion happens in the desert when wind (atmosphere) shapes the sand in the geosphere. Water (hydrosphere) can also shape land, such as in the formation of the Grand Canyon.
Humans have a huge impact on all spheres. Negative impacts, such as burning fossil fuels, pollute the atmosphere. Piling up our waste in landfills affects the geosphere. Pumping waste into the oceans harms the hydrosphere. And overfishing and habitat destruction can reduce the diversity of living things in the biosphere.
However, people everywhere are working to change things. Recycling efforts are increasing all over the world, and companies are finding new ways to reduce fossil fuels. In the US alone, people are recycling six times more than a generation ago.
