Explanation:

The rule of three or is a way of solving problems of proportionality between three known values and an unknown value, establishing a relationship of proportionality between all of them. That is, what is intended with it is to find the fourth term of a proportion knowing the other three. Remember that proportionality is a constant relationship or ratio between different magnitudes.

If the relationship between the magnitudes is direct, that is, when one magnitude increases, so does the other, the direct rule of three must be applied. To solve a direct rule of three, the following formula must be followed:

a ⇒ b

c ⇒ x

So,  

The direct rule of three is the rule applied in this case as follows: If the change in water level is 0.05 inches per hour, what is the change in water level after 24 hours?

How does the atomic mass of the atom change when an electron is added or removed?

Answers

If you could magically make two neutrons in the nucleus of an atom disappear, the atomic number and the electrical charge of that atom would remain unchanged. Neutrons do not carry an electrical charge so adding or removing them from the nucleus does not change the electrical charge of the nucleus. It does, however, change the mass of the nucleus. Adding or removing neutrons from the nucleus are how isotopes are created.

Protons carry a positive electrical charge and they alone determine the charge of the nucleus. Adding or removing protons from the nucleus changes the charge of the nucleus and changes that atom's atomic number. So, adding or removing protons from the nucleus changes what element that atom is! For example, adding a proton to the nucleus of an atom of hydrogen creates an atom of helium. (Actually, a few neutrons have to be added as well to make the new nucleus stable, but the end result is still helium.) Keep in mind that atoms, by definition, are electrically neutral and always contain the same number of protons and electrons.

DNA and RNA have base pairs that form hydrogen bonds with complementary bases. The DNA molecule shown contains adenine, cytosine, guanine, and thymine. Which base does RNA not have?
A) Thymine B) Adenine C) Guanine D) Cytosine

Answers

Answer:

Thymine

Explanation: I took the test

The DNA molecule shown contains adenine, cytosine, guanine, and thymine. The base that RNA does not have is Thymine. The correct option is A.

What are DNA and RNA?

DNA and RNA both are genetic materials, and they both represent the genetic material of living organisms. All animals contain DNA in their body. Some plants or bacteria contain RNA as genetic material.

DNA and RNA both contain bases that are attached with a hydrogen bond. These bases are adenine, cytosine, guanine, and thymine. In RNA, the same bases are present.

In RNA, in place of thymine, there is uracil present. Uracil and adenine are joined together with a hydrogen bond. Cytosine and guanine are present together with a hydrogen bond.

Thus, the correct option is A.Thymine, regarding the base present RNA.

state two advantages of parallel over series connection in table form?​

Answers

Advantages of parallel combination over series combination are:

1) In parallel combination each appliance gets the full voltage.

2) If one appliance is switched on/of others are not affected.

3) The parallel circuit divide the current through the appliances. Each appliance gets proper current depending on its resistance.

4) In a parallel combination it is very easy to connect or disconnect a new appliance without affecting the working of other appliances.

choose what you like!

Note that there are also some disadvantages to using parallel connections over series connections, such as increased complexity in wiring and the need for additional safety measures when working with high voltage circuits. The choice between series and parallel connections depends on the specific requirements of the circuit and the devices being used.
