Answer:
concentration of calcium ion mEq/L = 1.21 x 2 = 2.42mEq/L
Explanation:
given
- concentration of calcium ion in blood = 1.21 mmol/L
- Concentration in mEq/L = Concentration in mmol/L x valence of the ion
- The valence electron is the number of electron present in the outermost shell. Calcium belongs to the group2 elements also known as the alkaline earth metal, and their valence electron is 2.
- Hence, concentration of calcium ion mEq/L = 1.21 x 2 = 2.42mEq/L
where mEq/L = milliequivalent per liter
Think it is c but I could be wrong have not taken bio in a while
Answer:
While epidermal tissue mediates most of the interactions between a plant and its environment, ground tissue conducts the basic functions of photosynthesis, food storage, and support.
Prostatic acid phosphatase was purified from prostatic fluid. Monospecific antisera to the purified acid phosphatase was then produced in rabbits. When antibody was coupled with acid phosphatase, the enzymatic activity was markedly stabilized against pH and temperature degradation. Both acid phosphatase and rabbit anti acid phosphatase were non specifically coupled to Sepharose-4B using cyanogen bromide. Under these circumstances slight stability occurred when antibody was bound to Sepharose, and then acid phosphatase added to the gel antibody complex. When acid phosphatase was complexed to Sepharose, no stabilization occurred.
