bicarbonate can act as an acid or a base (i.e., donate or accept hydrogen ions) depending on conditions.
Under present-day conditions, these reactions buffer the pH of surface seawater at a slightly basic value of about 8.1 (above the neutral value around 7.0). At this pH, the total dissolved inorganic carbon (DIC ~ 2 mM) consists of approximately 1% CO2, 90% HCO3–, and 9% CO32– (Figure 2.1). The total boric acid concentration (B(OH)4– + B(OH)3)) is about 1/5 that of DIC. As discussed in section 2.2, increases in CO2 will increase the H+concentration, thus decreasing pH; the opposite occurs when CO2 decreases. We note that isotope fractionation between B(OH)3 and B(OH)4–is used for estimating past pH values
It should be oxygen because plants take in carbon dioxide, sunlight, and water and get rid of oxygen, energy, and water. (see pic)
The choices can be found elsewhere and as follows:
a. membranes lower the activation energy of biochemical reactions.
<span>b. reactants are within close proximity to each other. </span>
<span>c. membrane-bounded organelles act as catalysts for biochemical reactions. </span>
<span>d. reactants move faster within membrane-bounded organelles. </span>
<span>e. reactants are less likely to encounter each other within membrane-bounded organelles. </span>
The correct answer is option C. Membrane bounded organelles facilitate faster chemical reactions because it <span>act as catalysts for biochemical </span>reactions. Hope this answers the question.
Answer:
not sure but I think it's option C.
Answer:
The answer is the integumentary system. Hope that helps! :)
