Answer: I believe the answer is C. Contractions are informal
Explanation:
Mass<span> is the actual amount of material contained in a body and is measured in kg, gm, etc. Whereas </span>weight<span> is the force exerted by the gravity on that object mg. Note that </span>mass<span> is independent of everything but </span>weight<span> is </span>different<span> on the earth, moon, etc.</span>
Polymers are made of individual subunit called monomer.
<u>Explanation:</u>
Polymers are lengthy chains built up of replicating molecular subunits, named monomers. The term polymer becomes from poly- (many) and -mer (part). A polymer may be a real or manufactured macromolecule composed of recurring units of a smaller molecule (monomers). The term monomer comes from mono- (one) and -mer (part).
Monomers make polymers by creating chemical bonds or confining supramolecular by a method called polymerization. Examples of polymers comprise plastics like polyethylene, silicones. Polymerization is the method of covalently bonding the smaller monomers into the polymer. While polymerization, chemical groups are failed from the monomers so that they may join together.
Answer:
The box will move toward you with a force of 10N
Explanation:
If you and your friend are pushing the same box with the same amount of force, those two forces will balance each other out, and the box won't move. In the question, 20N will cancel each other out, and there will be 10N. Your friend is pushing the box with more force than you, so it will move toward you with the remaining force of 10N
Answer:
The correct answer is: (B) erythropoietin (EPO) – increases white blood cell production.
Explanation:
Erythropoietin is a hormone secreted by the kidney when dealing to cellular hypoxia (low oxygen content on body tissues) to stimulate red blood cell production. This is because red blood cells are the ones that transport oxygen to every tissue in the body.
