Answer: Integers are closed under multiplication.
Explanation:
Rational numbers are numbers of the form:
a/b
such that a and b are integers.
The axiom: " Integers are closed under multiplication. "
Says that if we have two integers, x and y, then:
x*y is also an integer.
So if we have two rational numbers,
a/b and c/d
Such that a, b, c and d are integers, and we multiply them, we have:
(a/b)*(c/d) = (a*c/b*d)
the numerator is a*c is the product of two integers, so this is an integer by the previous axiom.
the denominator is b*d, also a product of integers, so this is an integer.
then (a*d)/(b*d) is the quotient of two integers, then this is a rational number.
Answer:
the second one... Integers are closed under multiplication

Explain why fermentation stops after
a certain time in making
making bread?
Answer:
The yeast die at 140° F
Explanation:
The fermentation process is caused by the living organisms called yeast feeding on the sugar in the dough. As the yeast feed on the sugar they release CO² which causes the bread to rise but once the bread in the oven reaches 140° all the yeast are killed off and the fermentation process stops.
The process of fermentation stops after a certain time in making bread because the organism which carries this process has been killed.
What do you mean by Fermentation?Fermentation may be defined as a process a chemical process by which molecules such as glucose are broken down anaerobically in the presence of yeast.
During fermentation, the yeast produces excess carbon dioxide due to which the dough of bread swells. But after the completion of fermentation when bread places in the oven or any other warmer temperature, it killed the yeast, and hence fermentation stops.
Therefore, the process of fermentation stops after a certain time in making bread because the organism which carries this process has been killed.

Dump out half of the particles. Place your hand tightly over the top and shake the container. Then remove most of the remaining particles, and shake the container again. Compared with the full container, which states of matter do these two models most closely represent? Explain.
Answer:
solid
Explanation:
The two models explained are most closely representing the "solid" state.
As in both the models the techniques used are to separate particles through shaking technique and shaking is efficient gravity separation method which helps in separating solid particles such as while dealing with tungsten and tin.
Hence, the correct answer is "Solid".
Answer:
When the container was half full, the particles had more freedom to move around than they did when the container was full. A half-full container represents a liquid. When the container had only a few particles, they had lot more freedom to move about. So, this model represented a gas.

A. could not confirm the usefulness of sonar
B. could destroy the hypothasis of continental drift
C. could not provide a mechanism for moving continents
D. could explain how the seafloor was being destroyed
Answer:
C. could not provide a mechanism for moving continents
Explanation:
Magnetic reversals have the habit of causing geological displacements, since they are directly linked to the movements and distribution of tectonic plates on the planet, which are responsible for the movements of the continents. In this case,
if the discovery of magnetic reversals recorded on the ocean floor were not carried out, it would be impossible to establish its relationship with the movement of the tectonic plates, making it impossible to provide a mechanism for moving continents.

Explanation:
Which observation led Mendel to the idea that traits were controlled by more than a single factor? Crossing two purple-flowered pea plants always resulted in a purple-flowered pea plant. Crossing two white-flowered pea plants always resulted in a white-flowered pea plant. A trait that was not seen in the first generation may later reappear in the second generation. A trait that was not seen in the first generation was completely gone and never reappeared.
Answer:
The answer is option C.
Explanation:
Genetic traits are expressed by dominant and recessive genes, which show up in the phenotype according to their presence on the chromosomes.
Observing a trait that was not present in the previous generations suggests that this trait is recessive and did not have the chance to appear in the other generations before. This idea has led Mendel to the idea that traits were not controlled by only a single factor. So the answer is C.
I hope this answer helps.
Answer:
A trait that was not seen in the first generation may later reappear in the second generation.

Describe how the chemical bonds in unsaturated fatty acids make them more suited for cell
membranes than saturated fatty acids.
Answer:
Unsaturated fat, a fatty acid in which the hydrocarbon molecules have two carbons that share double or triple bond(s) and are therefore not completely saturated with hydrogen atoms. Due to the decreased saturation with hydrogen bonds, the structures are weaker and are, therefore, typically liquid (oil) at room temperature .

Can podocyte cells in the Bowmann capsule attach to any other basement membrane other than the glomerular basement membrane? That is, it can itself have a separate layer of base membrane?
Answer:
"Podocytes are cells in the Bowman's capsule in the kidneys that wrap around capillaries of the glomerulus. Podocyte cells make up the epithelial lining of Bowman's capsule, the third layer through which filtration of blood takes place.[1] The Bowman's capsule filters the blood, retaining large molecules such as proteins while smaller molecules such as water, salts, and sugars are filtered as the first step in the formation of urine. Although various viscera have epithelial layers, the name visceral epithelial cells usually refers specifically to podocytes, which are specialized epithelial cells that reside in the visceral layer of the capsule. "

Which of the following descries a solution that contain a buffer? A. Sodium hydroxide, a base, is added to the solution, and the pH of the solution becomes higher. B. Citric acid is added to the solution, but the pH of the solution does not change. C. Acetic acid is added to the solution, and the pH of the solution becomes lower. D. Distilled water is added to the solution, and the pH of the solution does not change.
Answer:
B. Citric acid is added to the solution, but the pH of the solution does not change.
Explanation:
In chemistry, buffer solutions or simply called Buffer are solutions that resist a change in pH when an acid or base is added to them i.e they maintain a constant pH. This is as a result of the content of the solution. A buffer may contain a weak acid and its conjugate base (salt) or a weak base and its conjugate acid.
Hence, when a strong base or acid is added to them, they still restore the original pH of the solution due to the reaction that removes or neutralizes the hydrogen or hydroxide ions from the acid and base added to them respectively. This is what happens when Citric acid is added to the solution, but the pH of the solution does not change.
Citric acid, which is an acid, does not practically increase or decrease the pH of the solution. Hence, the solution is called a buffer.
Answer:
Citric acid is added to the solution, but the pH of the solution does not change.

D. could explain how the seafloor was being destroyed
Answer:
C. could not provide a mechanism for moving continents
Explanation:
Without the discovery of magnetic reversals recorded on the ocean floor, scientists could not provide a mechanism for moving continents.
Magnetic reversals are responsible for geological shifts and depend on the distribution of tectonic plates that causes movements of continents.
Asymmetric movement of tectonic plates leads to movement of continents and the degree of asymmetry varies with the same rythm of the magnetic reversal rate.
Hence, discovery of magnetic reversals are important to identify the mechanism for moving continents.
The study of a living being is called biology.
The correct answer is C.
Without the discovery of magnetic reversals recorded on the ocean floor, scientists could not provide a mechanism for moving continents because magnetic reversals are responsible for geological shifts and depend on the distribution of tectonic plates that causes movements of continents.
