Answer:
12%
Explanation:
The percentage of Guanine and Cytosine in DNA are equal to each other, as one molecule of guanine bonds with one molecule of cytosine.
If 12% of the nitrogenous bases are guanine, then another 12% will be Cytosine.Conversely, the percentage of adenine and thymine in DNA are equal to each other.

Your friend is describing an element that is commonly
found in household materials, malleable, and a good
conductor of heat and electricity. They say it is not very
reactive and is very similar to the other elements in its
group. Your friend's element is most likely which of these?
A. A transition metal
B. A noble gas
C. A halogen
D. An alkali metal
An element that is commonly found in household materials, malleable, and a good conductor of heat and electricity. They say it is not very reactive and is very similar to the other elements in its group as an alkali metal.
What is an alkali metal ?All the elements listed in column 1A of the periodic table—hydrogen, lithium, sodium, potassium, rubidium, cesium, and francium—are classified as alkali metals. The fact that all of these metals contain one electron in their outermost layer of electrons binds them together.
The production of paper, detergents, and soap all need sodium hydroxide. In addition to being used as the electrolyte in alkaline, Ni-Cd, and Ni-MH batteries, potassium hydroxide is also used by farmers to make acidic soil more alkaline so that plants would grow better in it.
Vinegar, hydrochloric acid, and sulfuric acid are a few examples of the H = ion-containing compounds referred to as acids. Alkalis are a class of substances that feel soapy and contain the OH = ion.
Thus, option D is correct.

A group of earth science students were investigating in the laboratory. They took granite rock and limestone samples and massed
them on a balance. Then, students placed the rock samples in closed plastic vials. The students shook them vigorously for thirty
minutes. Students then massed the rocks again. What is the dependent variable in this experiment?
es )
A)
Why does granite rock break down more quickly?
B)
How do rocks interact during mechanical manipulation?
C)
Which rock type changes more due to physical weathering?
D)How does granite change shape after mechanical breakdown?
Answer:
Which rock type changes more due to physical weathering?
Explanation:
A dependent variable is the effect obtained by manipulating a cause. Hence, when you are carrying out an experiment, the variable that you manipulate is the independent variable while the effect that it produces is the dependent variable.
Therefore, when the both rock samples are shaken, the mass after shaking shows the extent to which the rock samples break down after a physical weathering process. This is the dependent variable because the extent of physical breakdown depends on the type of rock.

what are buffers and why are they important
Explanation:
A buffer is a solution that can resist pH change upon the addition of an acidic or basic components. It is able to neutralize small amounts of added acid or base,thus maintaining the pH of the solution relatively stable.This is important for processes and/or reactions which require specific and stable pH ranges.

What is the formula of a compound that has [1 mol Fe], [1 mol Ti], and [3 mol O]
Answer: [tex]FeTiO_3[/tex]
Explanation:
Molecular formula is the chemical formula which depicts the actual number of atoms of each element present in the compound.
Empirical formula is the simplest chemical formula which depicts the whole number of atoms of each element present in the compound.
The molecular formula for a compound that has [1 mol Fe], [1 mol Ti], and [3 mol O] will be [tex]FeTiO_3[/tex]

In order for the process to be endothermic, the energy required to break the lattice has to be _______ than the energy released as the ions go into solution.
a. Greater
b. Less
Explanation:
I honestly believe the answer is greater
If the energy required to break the lattice is less than the energy released as the ions go into solution, then the dissolution of solute is endothermic.
An endothermic reaction is one in which energy is absorbed. This implies that the energy change of the reaction is positive.
Now, if the energy required to break the lattice is less than the energy released as the ions go into solution, then the process is endothermic and energy is absorbed.
