Answer:
If a splinter of wood enters the skin and introduces microorganisms to the site the body would first release chemical mediators like histamine then cause vasoconstriction. Platelets work to make a blood clot then neutrophils come in and vacillation occurs. This causes redness, warmth, swelling and pain. Edema and pus formation occurs therefore the neutrophils work to rid the area of cell debris and pathogens. Later the lymphocytes and macrophages will finish the job of the neutrophils and scar tissue is formed to repair the damaged tissue.
Explanation:
I think it would be A. Because plants have bacteria on their roots that take the free nitrogen in the air from the soil and turn it into usable nitrogen. Animals could get usable nitrogen from eating plants since they have bacteria that make it. Then if an animal eats an animal that ate the plant, then it could get that nitrogen. But i am not completely sure though. I just learned this recently. I hope this helped :)

Answer:
525 grams
Explanation:
Assuming the solution to be prepared is 15% by weight calcium chloride, it means 15 grams of calcium chloride will be in 100 mL of solution.
To calculate the amount needed to make 3500 mL solution;
15 g is required to make 100 mL
X g is required to make 3500 mL
X = 15 x 3500/100
= 525 g
<em>Therefore, 525 grams of calcium chloride will be needed to make 15%, 3500 mL of calcium chloride solution.</em>
