Rudiy274 years ago

n=g/m therefore g=n*m
G = 102 * (Molar mass of magnesium)
G = 102 * (24.30) --> i'm guessing its just mg and not mg2..?
G = 247.6 Grams of magnesium

Mrs. DeFord wanted to know whether or not her students would do better on a quiz if she promised them candy.
marta [7]

Answer:

a.) Independent Variable: # of candy bars promised to each group

[ The Independent Varaiable is what you change in the experiment]

b.) Dependent Variable: Quiz Scores

[ The Dependent Variable is what you're testing in the experiment; what the experiment should affect]

c.) Constant(s): Same Quiz, same number of gender kids in each group, same age kids in each group, same ability, and same background. [and same time, I'm assuming.]

[Constants are what you keep the same in the experiment; what you're not changing.]

d.) Testable Question: Will promising kids candy make them do better on tests and quizzes? [or something along this lines of this]

[The Testable Question is what you're trying to find out in the experiment]

e.) Hypothesis: The more candy the students were promised, the better results Mrs. DeFord would get from them.

[The Hypothesis is what the person performing the experiment expects will happen; an educated guess]

f. Formal Conclusion: Data shows that kids who were promised more candy had a better average than kids who were promised less candy/none. Mrs. DeFord's hypothesis was correct, since she assumed the more candy the students were promised, the better they would do on the quiz.

[The Formal Conclusion is what you have learned from the experiment, and wether or not the hypothesis was correct or not.]

I hope this helps! :)

A straight chain hydrocarbon with the formula C^3H^4 _____.
Yakvenalex [24]

Answer:

has two double C-C bonds

Explanation:

A saturated compound is a compound having the full complement of hydrogen atoms for every carbon atom while an unsaturated compound does not contain the full complement of hydrogen atoms for every atom of carbon.

If we look at C3H4, the only possible structure of the compound is H2C=C=CH2. We can see from this arrangement that the compound contains a cumulative double bond. This is the specific structure that fits into one of the descriptions in the options, the compound contains two double bonds.

Glucose and amino acids are reabsorbed from the glomerular filtrate by the __________.
AleksandrR [38]

Answer:

Amino acids, along with glucose, are reabsorbed in the glomerular system with a passive or active mechanism as the fluid travels through the entire renal tubular system and enters the circulation again.

Active mechanisms are those that require expenditure of energy, that is, expenditure of the energy currency, while the passive ones do not, they occur through spontaneous non-energy processes such as osmosis, the osmotic gradient and the difference in concentrations in different compartments.

Explanation:

Glomerular filtration is the regulator of the excretion of metabolites and toxic molecules or not necessary for our body. That is why if the amino acid values ​​are high as well as those of glucose in urine, we will be facing a pathology.

If glucose is increased, it is because there is a glycemic peak in blood volume, hence possible diabetes.

And if the amino acids are increased, we could be facing an autoimmune or proteolytic pathology where a large amount of body proteins such as muscle proteins would be breaking down and releasing the amino acids that make it up, this phenomenon usually appears in those people who suffer from rhabdomyolysis in expenses very intense energy sources not appropriate.

On the other hand, glomerular filtration occurs in the kidney and is carried out by the nephron, which is the functional unit of the kidney, within it there is a specific tubular system in collection, absorption and reabsorption, added to the presence of Bowman's capsule.
