A pepsina é uma enzima digestiva cuja velocidade de reação é influenciada tanto pelo pH quanto pela temperatura do meio. Fixada a temperatura, a velocidade de reação varia com o pH como mostrado no gráfico a seguir. a) Planejou-se um experimento para verificar qual a temperatura que determina a velocidade máxima da reação. Cinco tubos de ensaio contendo pepsina e um substrato adequado são colocados em diferentes temperaturas. Complete a tabela I, indicando o valor do pH que deve ser usado em cada um dos tubos.

name and explain one of the event that occurs during meiosis that increases the variation in offspring even more than simple reproduction?

a. seed plant structure. 1. the three main plant organs are roots, stems, and leaves. a fourth kind of tissue, meristematic tissue, is responsible for plant growth. meristematic tissue is the only plant tissue that produces new cells by mitosis. plants can lose water out of their leaves as they exchange gases with the air

explanation:

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.
