a sample of double-stranded dna contains 42% cytosine. approximately what percent of the nucleotides in this sample will be thymine?
Answer:
8% thymine
Explanation:
The percent of thymine in the given sample of the DNA will be equal to 8 %.
What is the structure of DNA?DNA, according to Chargaff, is composed of nucleotide subunits. These nucleotides are linked through two or more hydrogen-bonded to one another to form the double-stranded molecule of DNA.
The nucleotides found in the DNA molecule are Adenine, Thymine, Cytosine, and Guanine. Guanine (G) pairs with Cytosine (C) while Adenine (A) pairs with Thymine (T).
According to Chargaff's rule, the amount of Adenine is equal to that of Thymine in a DNA molecule and the same applies to Guanine and Cytosine. We can consider that the total amount of nucleotides equals 1 or 100%.
[tex]A + T + G + C = 100\%[/tex]
If Cytosine is 42 % of the DNA sample, this means that guanine will also be 42%.
G + C = 42 + 42 = 84%
A + T = 100% - 84 % = 16%
This means that Adenine and Thymine amount to 16 %. The amount of each nucleotide will be 16% ÷ 2 = 12% i.e. A = T = 8 %
Therefore, the percent of thymine in the given sample of the DNA will be 8 %.

of its particles?
A. Nuclear energy
B. Thermal energy
Ο Ο Ο
C. Electrical energy
D. Chemical energy
Answer:
Thermal Energy
Explanation:
Thermal energy is the total internal kinetic energy of an object due to the random motion of its atoms and molecules They consist of the sum of the internal kinetic energy (thermal energy) and the potential energy of an object.
Answer:
B. thermal energy.
Thermal energy or heat is due to the movement or vibrations of tiny particles such as atoms and molecules.

What is true of a saturated solution?
Answer:
A saturated solution is a solution that contains the maximum amount of solute that is capable of being dissolved. At 20°C, the maximum amount of NaCl that will dissolve in 100. g of water is 36.0 g. If any more NaCl is added past that point, it will not dissolve because the solution is saturated.
What are the ways that heat transfers? identify common examples of heat transfer.
Answer:
Conduction is the process of heat being transferred between objects through direct contact, and it's the most common type of heat transfer. For example, in cooking the burners on stoves will conduct heat energy to the bottom of a pan sitting on top of it. From there, the pan conducts heat to its contents.

People who have certain lung diseases, such as emphysema or lung cancer, often have to use oxygen from tanks. A large volume of oxygen can be put into a small tank because oxygen is a gas, and gases can be_________.
Answer:
I believe the answer is compressed
Explanation:
The answer may be a slightly different word, but if it's looked at by a human and not a robot compressed should work too
Gases can be compressed by applying high pressure. Thus large volume of oxygen can be contained in a tank by compressing the gas with high pressure.
What are gases?Gases are substances in state where its molecules are located far apart and are able to spread in the surroundings. This property of spreading based on the concentration difference is called diffusion.
Thus, gases diffuse from high concentrated area to lower concentration region. Gaseous substances does not have a certain volume, mass or shape. But when they are collected into a container then the volume will be that of the container.
in liquid state, molecules are some more closer in comparison to gases and an intermolecular attraction of force bind these molecules together to have a certain volume and mass. Whereas in solids, all the molecules are tightly packed.
Gases can be liquified by applying high pressure at low temperature so that the distance between molecules can be decreased and an intermolecular force of attraction occurs there.
So that large volume of gases can be collected to a tank by compression using high pressure.

Why do you think the term ionic is used to describe compounds formed from a metal element and a nonmetal element?
Answer:
All compounds form when atoms of different elements share or transfer electrons. Compounds in which electrons are transferred from one atom to another are called ionic compounds.
Explanation:
Because the positive and negative charges cancel out, an ionic compound is neutral in charge.

Answer:
C. When the objects are oppositely charged
