What is found between the monomers on the different strands of DNA
Phosphodiester bonds found between the monomers on the different strands of DNA.
What is DNA ?Deoxyribonucleic acid is called as DNA. The molecule found inside cells that carry the genetic material necessary for an organism to develop and function. This knowledge can be passed on from one generation to the next thanks to DNA molecules.
The information molecule is DNA. It contains information needed to create proteins, which are other big molecules.
In DNA polymers, phosphodiester bonds link the 5' carbon of one nucleotide and the 3' carbon of another nucleotide. In a DNA polymer, phosphodiester bonds strong electromagnetic attractants join the nucleotide monomers together.
Thus, Phosphodiester bonds found between the monomers on the different strands of DNA.

In the interactive, start adding neutrons to the nucleus.
What happens to the mass number each time you add a neutron, and why?
Answer:
Explanation:
Each time you add a neutron, it adds one mass number to the mass because each neutron and proton weighs approximately 1 amu.
Answer:
The mass increases
Explanation:
When protons and neutrons are added, the mass increases. Electrons, on the other hand, are so small they do not affect the mass.

An investigation was done with an electromagnetic system made from a battery and wire wrapped around a nail. Different sizes of nails were used. The number of paper clips the electromagnet could pick up was measured. What's the independent variable and dependent variable?
Answer:
Independent variable: SIZE OF NAILS
Dependent variable: NUMBER OF PAPER CLIPS
Explanation:
The independent variable in an experiment is the variable that is changed or manipulated by the experimenter in order to effect a measurable response. In this investigation, the DIFFERENT SIZES OF NAILS USED is the INDEPENDENT VARIABLE.
The dependent variable is the variable that is measured in the experiment. It is the variable that responds to changes made to the independent variable. In this investigation, THE NUMBER OF PAPER CLIPS the electromagnet could pick up is the DEPENDENT VARIABLE.
The dependent variable is the number of paper clips that the electromagnet could pick up while the independent variable is sizes of nail used.
An experiment consists of;
a dependent variable and an independent variable.The independent variable is the variable that is being manipulated while the dependent variable changes with changes in the independent variable.
In this experiment, the dependent variable is the number of paper clips that the electromagnet could pick up while the independent variable is sizes of nail used.

Explanation:
Joelle is a manager at a construction company, and she is interested in the chemistry behind the materials they use. She has begun studying the materials used to fill walls. She knows that to keep the temperature inside a room steady the material must be a thermal insulator, and she predicts that materials should not be acidic or else they would dissolve too easily in water.
Which of these is a molecular ingredient that could be used in a wall-filling material ?
C6H6
Na6Ba6
NeNa
HCl
Answer:
C6H6
Explanation:
Now let us take a recap of Joelle's criteria for a wall filling material;
1) the material must be a thermal insulator
2) materials should not be acidic
3) they will not dissolve too easily in water.
If we consider the options provided, Na6Ba6 and NeNa do not exist. HCl is an acid and does not match Joelle's criteria. Hence the answer must be C6H6.

Explanation:
When a liquid freezes into a solid, the particles of the substance:
A.Lose energy
B.Gain energy
C.Move faster
D.Disappear
Answer:
(see below)
Explanation:
Using process of elimination:
A) lose energy
When a liquid freezes into a solid, the particles move a lot slower because the once-flowing particles are now about to be stuck in place, barely vibrating in its structure.
So, yes, they has lost energy, but there can be a better answer.
B) gain energy
When a liquid freezes into a solid, the particles move a lot slower, so there is no way there is more energy now. If there was to be more energy, it would be a gas now.
So, no, they did not gain energy.
C) move faster
When a liquid freezes into a solid, the particles move a lot slower, so there is no way they're moving faster now. Otherwise it would be a gas now.
So, no, they did not move faster.
D) disappear
Particles of a substance don't just . . . disappear. There is no way matter can be destroyed or created, only changed in form, according to the Conservation of Matter.
So, no, they did not disappear.
So the answer is most likely A.
What's the difference between the "matter that makes up wood" and the "matter that makes up water"? Explain your ideas in full sentences.
They describe different forms of matter, solid and liquid. As well as both being entirely differently structured forms of matter.
They distinguish between solid and liquid matter. In addition to being completely different types of matter.
What is matter?Matter is defined as everything that takes up space other words, the "material" that makes up the universe.
All matter is composed of substances known as elements, each of which has unique chemical and physical properties and cannot be decomposed into other materials through ordinary chemical reactions.
Atoms and molecules make up some of the material in the category of solids, liquids, and gases.
The matter that makes up wood have characteristics of any solid, i.e., high intermolecular force of attraction that holds it shape.
The matter that is making water will have liquid characteristics, which do not have a particular shape and will have weak intermolecular forces of attraction.
Thus, this is the chief difference between the "matter that makes up wood" and the "matter that makes up water".

A. λ = 3 m
B. E = 1.9878 x 10⁻³³ J
C. Total energy : 1.9878 x 10⁻²⁰ J
Further explanationThe photoelectric effect is an electron coming out of a metal because of electromagnetic radiation
One type of electromagnetic radiation is light
Radiation energy is absorbed by photons
The energy in one photon can be formulated as
[tex]\large{\boxed{\bold{E\:=\:h\:.\:f}}}[/tex]
Where
h = Planck's constant (6,626.10⁻³⁴ Js)
f = Frequency of electromagnetic waves
f = c / λ
c = speed of light

Describe the development of the periodic table.
Mendeleev's holes have long since been filled in and new elements have been added to the periodic table.
What is periodic table?Periodic table is defined as a list of chemical elements that are ordered in atomic number order, typically in rows, with comparable chemical elements appearing in vertical columns because of their similar atomic structures. The table can be used by scientists to anticipate chemical reactions, study trends in the periodic properties of certain elements, and speculate on the properties of yet-to-be-discovered elements.
The structure for the contemporary periodic table was developed in 1869 by Russian chemist Dmitri Mendeleev, who left spaces for elements that had not yet been discovered. He organized the elements into groups based on their atomic weight, rearranging them if necessary if he found that they did not fit.
Thus, Mendeleev's holes have long since been filled in and new elements have been added to the periodic table.
