Answer:
An element is made of one type of atom, while a compound is two or
more types of atoms combined.
Explanation:
An element is a distinct substance that cannot be split up into simpler substances. Elements are substances that consists of only one kind of atom.
Compounds are substances composed of two or more kinds of atoms/elements joined together in a definite grouping.
- There are over a hundred elements known to date.
- Each one of the elements is symbolized by a capital or a capital letter followed by a small letter derived from English, Latin or Greek
- Examples are copper, gold, iron
- The properties of a compound are distinct and different from those of the individual elements that are combined in its make up.
- There are several millions of compounds known.
- They are usually represented by chemical formulae.
As we can see, compounds are indeed made up of more than one types of atoms whereas an element is made up of just one single atom.

D carnivore
Explanation:

For an ideal gas, we use the ideal gas equation to relate pressure, volume and temperature changes. It is expressed as:
PV=nRT
For this case, we set V, n as constant.
P/T = nR/V = constant = k
P = kT
P1/T1 = P2/T2
P1/T1 = 2P1 / T2
T2 = 2P1(T1) / P1
T2 = 2T1
Therefore, in order to double the pressure of the system, we need to double the temperature as well at constant volume and number of moles.
Answer:
The correct answer is - D. It gets rid of pathogens that invade the body.
Explanation:
Like all other organ systems, the immune system is an organ system that involves several special organs that helps in fighting any foreign object or infection that invades our body. This organ system produces specific cells or chemicals to fight or kill the microbes, and unnatural change takes place in the body.
The organs involved in the immune system are lymphocytes or white blood cells, the complement system, antibodies, the lymphatic system the thymus, bone marrow, and the spleen.
All these combinedly helps in fighting, killing the microbes or infections that occur in the body, and correct the physiological changes that occur in the body to get rid of pathogens that invade the body.
This can tell you alot. its about what you are learning but it can affect the way that the substance bonds to others or how high the boiling and melting point are. hope this helps some.
