(a) The serum is the plasma without <u>clotting</u> factors.
(b) Phagocytic cells are <u>neutrophills</u> and monocytes.
(c) Eosinophils are linked with <u>allergic</u> reactions.
(d) In clotting, <u>calcium</u> ions play an important role.
(e) In an ECG, one can determine the heartbeat rate by counting the number of <u>QRS complex</u>.
<h3>EXPLANATION:</h3>
»» Blood without blood corpuscles is called plasma and plasma without clotting factors is called serum.
»» The professional phagocytes include many types of white blood cells (such as neutrophils, monocytes, macrophages, mast cells, and dendritic cells).
»» Eosinophils are associated with allergic reactions.
»» Calcium ions play a significant role in clotting.
»» When the cardiac rhythm is regular, the heart rate can be determined by the interval between two successive QRS complexes.
To ensure that you get the right concentration of sanitizing solution, follow <span>the label instructions and use a test strip. The correct option among all the options that are given in the question is the second option or option "b". I hope that this is the answer that has come to your desired help.</span>
A. land plants, tiny water plants
a. slug, frog, newt
b. plants, slug-insect-water fleas, frog-fish-newt, perch-fox, heron
c. water fleas, diving beetles
d. heron, perch
e. one thing that could happen if all frogs suddenly died is that there would be an overpopulation of slugs, insects, and beetles. another thing that could happen would be that foxes would only rely on getting slugs for food so the slugs would soon go extinct and the plants would possibly over populate.
hope this helps!!
