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 1

Answer:

Thymine

Explanation: I took the test

Answer 2

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.

When you change the number of protons in an atom, you will change the atom from one element to a different element. Sometimes, when you add a proton to an element, the element will become radioactive. If you change the number of electrons in an atom, you will get an ion of the element.

Which is a true statement about a zero net force?
A zero net force causes a change to an object’s direction.
B.zero net force causes a change to an object’s speed.
C.A zero net force causes a change to an object’s acceleration.
D.A zero net force causes no change in an objects motion.

Answers

Answer:

D)a zero net force causes no change in an objects motion.

A zero net force causes no change in an object's motion. This statement is true about zero net force. Therefore, option D is correct.

What is zero net force ?

An item that is originally at rest and has no net forces operating on it will stay at rest. If it is going, it will keep moving straight forward at a consistent speed. Forces are "pushes" or "pulls" on the object, and they are vector numbers, just like acceleration and velocity.

A automobile travelling at 50 mph on a highway continually has a net force of zero even though it is moving, since there is no acceleration and the speed is constant.

The total net force acting on an object as it moves at a steady speed is always zero. If you apply force, friction or another force (or several forces) will balance it out.

Thus, option D is correct.

A piece of aluminum has a mass of 12.0 g. When it is placed into a graduated
cylinder with 14.0 mL of water, the water level rises to 18.5 mL. What is the density
of aluminum?
0 2.66667g/ml
O 2.67 g/mL
O 2.667g/mL
O 2.7 g/mL

Answers

Answer:

The answer is 2.7 g/mL

Explanation:

The density of a substance can be found by using the formula

[tex]density = \frac{mass}{volume} \\[/tex]

From the question

mass = 12 g

volume = final volume of water - initial volume of water

volume = 18.5 - 14 = 4.5 mL

So we have

[tex]density = \frac{12}{4.5} \\ = 2.66666666...[/tex]

We have the final answer as

2.70 g/mL

For the n = 3 electron shell, which of the following quantum numbers are valid? Check all that apply.

Answers

Answer:

The valid quantum numbers are l=0, l=-2 and l= 2.

Explanation:

Given that,

n = 3 electron shell

Suppose, the valid quantum numbers are

l = 3

m = 3

l = 0

m = –2

l = –1

m = 2

We know that,

The value of n = 3

Principle quantum number :

Then the principal quantum number is 3. Which is shows the M shell.

So, n = 3

Azimuthal quantum number :

The azimuthal quantum number is l.

[tex]l=0,1,2[/tex]

Magnetic quantum number :

The magnetic quantum number is

After fifteen minutes, he turns off the flame and allows the sample to cool. He records his final observations in the data table.

Which is the best explanation of his results?

The heating changed some of the sample to gas, causing the mass to decrease without breaking down the sample. Therefore, the original sample is a compound.
The appearance stayed the same, showing that the sample was not broken down by heating. Therefore, the original substance is an element.
The mass decreased during heating and some of the impurities escaped. Therefore, the original substance is an element.

Human body uses the energy provided from food digestion. Endothermic or exothermic?

Answers

Answer:

Endothermic

Explanation:

Exo is outside so exothermic would be outside the body

The carbohydrates are break down into glucose. Then glucose combines with oxygen in the cells and provides energy. Hence, digestion is an exothermic process.

What is an exothermic process ?

Food digestion produces heat. This happens as a result of the organism releasing heat during meal digestion. A process that releases heat is exothermic.

Heat is released during an exothermic reaction, raising the temperature of the immediate environment. The environment is cooled through an endothermic process that absorbs heat.

Glucose is created by the breakdown of these carbs. In the cells of our body, this glucose interacts with oxygen to produce energy. So, the process of digesting is exothermic.

Chemical processes involved in food digestion disassemble large food molecules into smaller, more manageable "building block" components.

Thus, Human body uses the energy provided from food digestion is exothermic process.

The mass of an atom Is found by adding Its protons and .The electric charge of an atom Is found by adding the charges carried by Its protons and .​

Answers

Answer: the 1st answer is neutrons and i think the 2nd is nucleus

Explanation:

The mass of an atom is found by adding its protons and neutrons. The electric charge of an atom is found by adding the charges of its protons and electrons.

What is atomic mass?

The atomic mass of an element is the total number of protons and the number of neutrons carried by one atom of that element. The atomic mass of an element is usually expressed in grams or a.m.u.

The atomic mass of an element = No. of protons + No. of neutrons

or

The atomic mass of an element = No. of electrons + No. of neutrons

The atomic number gives us information about how many protons are inside the nucleus of the atom. Elements are recognized by the number of protons in the nucleus. Neutrons are uncharged elementary or subatomic particles that are stable when bound in an atomic nucleus.

As the electrons and protons are charged particles in an atom, therefore, the sum of the charge carried by them is equal to the electrical charge of the atom.

For a neutral atom, the number of protons present in an atom is always equal to the number of electrons.
