Scientists and nutritionists have long suspected that high-fructose corn syrup, used to

sweeten soft drinks, is one of the causes of childhood obesity. In a recent study, at the

University of Cincinnati, researchers found that mice that drank water with added

fructose ate less solid food, gained more weight, and put on 90% more body fat than

mice that drank only water. Scientists concluded that fructose may affect metabolism in

a way that favors fat storage.

What is the independent variable?

The mice that drank only water

The presence of fructose in their diet

The quantity of water provided

The weight gained by the mice

Answer:

I beleive its the middle/second option :)

Explanation:

Sorry if I'm wrong but Newton's third law is "for every action (force) in nature there is an equal and opposite reaction." meaning if object A exerts a force on object B, then object B also exerts an equal and opposite force on object A so I beleive the moon would push up on the astronaut with a force of 300 N

During electrolysis a metal chemically decompose and deposits on the cathode where as the metal from the other electrode forms its ions in the electrolyte solution.

Electrolysis is the process of chemical decomposition brought out by the passage of electricity through an electrolyte in which the decomposed metal deposits on one electrode.

Electrolysis involves oxidation of one metal and reduction of the other. The prediction of the products of electrolysis requires a consideration of several factors including the potential at which the competing species are discharged at the electrode , if the electrode used are reacted or inert etc.

The oxidation reaction involves the formation of cations in the solution and the reduction involves the deposition of metallic substance at the cathode.

Answer:

Protons

Explanation:

I'm not exactly sure if this is what your question, but the number of protons is what makes an atom that atom. If you change the number of proton it is now a different atom. You change the number of electrons and get an ion or change the number of neutrons and get an isotope but you can't change the number of protons as you would be changing the elemnt.

Answer:

Answer Option A) To attain a noble-gas electron configuration.

Explanation:

Correct answer from test

Taking into account the definition of covalent bond and octet rule, the correct answer is option A.  Atoms share electrons in covalent bonds to achieve a noble gas electron configuration.

The covalent bond is the chemical bond that occurs between atoms of non-metallic elements. These atoms have many electrons at their outermost level and have a tendency to share them to acquire the stability of the noble gas electronic structure. In this way a molecule is formed.

The tendency of the elements to reach a stable configuration is known as the octet rule. For this, the octet rule explains that there must be eight electrons in their last energy levels, thus acquiring the structure of a noble gas.

So, a covalent bond is a force that joins two atoms of non-metallic elements to form a molecule in order to comply with the octet rule.

Finally, the correct answer is option A.  Atoms share electrons in covalent bonds to achieve a noble gas electron configuration.

Answer:4400

I went over this problem multiple times and I finally found the soultion

The concept of significant figures are mainly used by scientist and engineer to know the significance of digits in a measurement. Therefore, 4400L is the solution to the equation rounded to the correct number of significant figures.

Significant figures are the figures that indicate the degree of accuracy of a value. It tells about the precision of a value. It gives an idea about the digits that are necessary to indicate the experimental value.

Rules for counting significant figures are:

Number between 1 to 9 is always significant

Zeroes after a number has got no significance

Zeroes before a number has got no significance

Zeroes between number has got significance

4700 L - 281.4 =4400L

Therefore, 4400L is the solution to the equation rounded to the correct number of significant figures.

Two or more than two atoms with different physical or chemical properties can not combine together to form an element. An element  cannot be broken down into simpler substances by a chemical change. The correct option is option A.

Element generally consist of atoms or we can atoms combine to form element. Atoms of an element is always same, means all the properties of all atoms of one type of element is same.

Element is the basic unit of any compound and molecule which can not be broken further. Mixture, solution and compound are composed of two or more than two elements which can be further broken down easily.

Answer:

It is secondary succession.

Explanation:

primary succession only occurs in areas where there was no previous ecosystem

In the production of maple forest over the 1,000 years period, there has been the presence of the lake. Thus the production in the lake has been the secondary succession.

The primary and secondary succession has been the development process in the ecosystem. The ecosystem development can be taken place when there has been no previous vegetation, or when there has been the available ecosystem.

The primary succession can result when there has been no available previous ecosystem. The secondary succession can take place when there has been a previously existing ecosystem.

The atomic radius is basically the distance between the nucleus of the atom and the outermost electron in the farthest orbital of the atom. The more bigger the atomic radius , the less powerful is the force that holds together the nucleus and its electrons.

Answer:

Not all substances dissolve in all solvents

Explanation:

In chemistry, a common rule for determining if a solvent will dissolve a given solute is "like dissolves like." Solvents composed of polar molecules, such as water, dissolve other polar molecules, such as table salt, while nonpolar solvents, such as gasoline, dissolve nonpolar substances such as wax. Some substances are strong enough to not dissolve.

Fossils are essentially clues that have been left behind by various forms of living things. They are instrumental tools for understanding the diverse groups of organisms that have inhabited our planet at one time or another. A fossil is any preserved evidence of an organism.
