PLEASE HELP!! Paramecia are single‑celled aquatic eukaryotes that can survive in a wide range of salinities. Paramecia use contractile vacuoles to help maintain homeostasis under these varying salt conditions. The contractile vacuoles fill with fluid and then contract to remove the fluid from the paramecia. Scientists wished to determine the effect of salinity on contractile vacuole activity. They maintained different groups of paramecia in water of different salinities for one month. They then measured the average amount of fluid ejected from the contractile vacuoles in each group of paramecia each time the vacuoles contracted (Table 1).

Describe how the phospholipids of a plasma membrane regulate the movement of small or non-polar molecules across the membrane. 2pts. Explain how osmosis will affect animal cells when the cells are placed into an environment with a high water potential (low solute concentration) compared to the intracellular water potential. 2pts. Why does the paramecium move lots of water at the beginning of the experiment as compared to the end? 1pts

not sure if this what   you'r looking for would be percent composition

hypoxemia refers to a below usual concentration of oxygen in the blood, mainly in the arteries. hypoxemia is an indication of an issue associated with circulation or breathing and may lead to various symptoms like shortness of breath.  

the condition is identified by determining the level of oxygen in the blood sample obtained from an artery. it can also be predicted by determining the oxygen saturation of the blood with the application of a pulse oximeter.  

the normal arterial oxygen is about 75 to 100 mm hg. the values underneath 60 mm hg is generally considered with the requirement for supplemental oxygen. the normal pulse oximeter readings generally range between 95 to 100 percent. the values under 90 percent are regarded as low.  

in the given case, the oxygen saturation is measured at 93 percent, hence, there is no need to administer oxygen, that is, one should withhold oxygen.  

one part of the electromagnetic spectrum that arrives on earth as solar radiation from the sun is the visible spectrum. wavelengths of the visible spectrum combine to form what we refer to as

answer - d) ultraviolet radiation.

violet /   380–450 nm / 668–789 thz

violet is number 1 in the chart of visible light.
