Answer:
Motion is defined as phenomenon in which an object move from one place to another over a time.
Generally there are four types of motion: Linear, rotary, reciprocating and oscillating.
Linear motion: In this motion an object moves in a straight line. for example: an athlete running in a straight line.
Rotary motion: In this motion an object moves around an axis. For example: Wheel.
Reciprocating motion: In this motion an object moves in a continuous up and down motion or back-and-forth motion. For example: piston.
Oscillating motion: In this motion an object moves in a swinging motion (backwards and forwards) on an axis. For example: Pendulum.

dont kill me if im wrong >.<
In cellular respiration, energy is converted from glucose, which can be done with and without oxygen
Answer:
A sugar called deoxyribose.
Explanation:
DNA is made up of molecules called "nucleotides". These are:
- A phosphate group
- A pentose sugar [deoxyribose]
- A nitrogen-containing base [adenine, thymine, guanine and cytosine]
Thus the first option is the right answer.
Reasons why the other options are wrong:
"A plasma called haemoglobin" is wrong as plasma and haemoglobin are related to the blood.
"A chemical called nucleic acid" is wrong as it is not what DNA's made up of. DNA and RNA are nucleic acids themselves.
"An acid called chlorophyll" is wrong as chlorophyll is related to plants.
