Answer the following question given this paragraph: The motion of individual molecules in a gas is random in magnitude and direction. However, a gas of many molecules has a predictable distribution of molecular speeds, known as the Maxwell-Boltzmann distribution. Q: What do we call the predictable distribution of molecular speeds found in gas of many molecules? Choices: - mitchell - boltzmann distribution - burns - boltzmann distribution - kemp - boltzmann distribution - maxwell-boltzmann distribution A:
maxwell-boltzmann distribution

Answer the following question given this paragraph: Chemical reactions constantly occur inside the cells of living things. However, under the conditions inside cells, most biochemical reactions would occur too slowly to maintain life. That's where enzymes come in. Enzymes are catalysts in living things. Like other catalysts, they speed up chemical reactions. Enzymes are proteins that are synthesized in the cells that need them, based on instructions encoded in the cells' DNA. Q: What proteins synthesized in cells act as catalysts? Choices: - hormones - virophages - byproducts - enzymes A:
(Answer)
enzymes
Ques: Answer the following question given this paragraph: Q: What chambers are responsible for pumping blood out of the heart? Choices: - vacuoles - cells - valves - ventricles A:
Ans: ventricles

Answer the following question given this paragraph: Inhaling is an active movement that results from the contraction of a muscle called the diaphragm. The diaphragm is large, sheet-like muscle below the lungs (see Figure below ). When the diaphragm contracts, the ribcage expands and the contents of the abdomen move downward. This results in a larger chest volume, which decreases air pressure inside the lungs. With lower air pressure inside than outside the lungs, air rushes into the lungs. When the diaphragm relaxes, the opposite events occur. The volume of the chest cavity decreases, air pressure inside the lungs increases, and air flows out of the lungs, like air rushing out of a balloon. Q: Contraction of what large, sheet-like muscle results in inhalation? Choices: - pelvic floor - uterus - deltoid - diaphragm A:
(A).
diaphragm
Ques:Answer the following question given this paragraph: Sedimentary rocks form when sediments are compacted and cemented together. Sediments are pieces of rock. They may be gravel, sand, silt, or clay. Some sedimentary rocks form the solid minerals left behind after a liquid evaporates. Q: What type of rocks form when sediments are compacted and cemented together? Choices: - metamorphic rocks - crystalline rocks - igneous rocks - sedimentary rocks A:

Ans:sedimentary rocks
Ques:Answer the following question given this paragraph: An esterification is a condensation reaction in which an ester is formed from an alcohol and a carboxylic acid. Esterification is a subcategory of condensation reactions because a water molecule is produced in the reaction. The reaction is catalyzed by a strong acid, usually sulfuric acid. When the carboxylic acid butanoic acid is heated with an excess of methanol and a few drops of sulfuric acid, the ester methyl butanoate is produced. Methyl butanoate has the scent of pineapples. The reaction is shown below with both molecular and structural formulas. Q: What do you call a condensation reaction in which an ester is formed from an alcohol and a carboxylic acid? Choices: - transesterification - esterisation - decarboxylation - esterification A:

Ans:
esterification
