Answer: Single cell organisms dont need a respiratory system because oxygen and carbon-dioxe diffuses between their body tissues and the enviorment.
Answer:
c. Glutamine is metabolized by deamination, oxidation, and acidification.
Explanation:
Bicarbonate ions are an important part of bicarbonate buffer system which helps to maintain the pH of blood. Whenever blood starts to become acidic, bicarbonate ions increase to neutralize its effect. Their concentration can be increased by many mechanisms, for example tubular reabsorption.
However, glutamine catabolism does not replenish bicarbonate ions, in fact it does the exact opposite. Kidney generates ammonium ions by catabolism of glutamine which are excreted in the urine. This process also facilitates the excretion of bicarbonate ions.
C( both options. Hope it helps!!!!
Tonicity is the concentration of solutes dissolved in a solution which determines the direction and extent of diffusion. Hypertonic is when the concentration of solutes is higher outside the cell than inside, so water flows in and the cell shrinks. Hypotonic is when concentration of solutes is higher inside cell than outside, water flows out and the cell bloats. Isotonic is equilibrium, water is flowing in and out.
Explanation:
A gas can be converted into a liquid by increasing the pressure & decreasing temperature. So that the condensation occurs. You must also make the molecules closer so that it is a phase change from a gas to liquid. In liquids, the molecules are very near than that of gases.
