What is the speed of light?
- A.
  
  259 285 478 m / s
- B.
  
  300 792 458 m / s
- C.
  
  299 792 458 m / s
- D.
  
  276 157 478 m / s
Correct Answer
C. 299 792 458 m / s

Explanation
The speed of light is a fundamental constant in physics and is denoted by the symbol "c". It is approximately 299,792,458 meters per second (m/s). This value represents the speed at which light travels in a vacuum. It is an important constant in various scientific equations and theories, including Einstein's theory of relativity.

Do tomatoes have more genes than humans?
- A.
  
  True
- B.
  
  False
Correct Answer
A. True

Explanation
A tomato has 31,760 genes - 7,000 more genes than a human being

4.

Humans share 50% of their DNA with which fruit?
- A.
  
  Banana
- B.
  
  Apple
- C.
  
  Orange
- D.
  
  Pear
Correct Answer
A. Banana

Explanation
Banana is the correct answer because humans share approximately 50% of their DNA with bananas. This is due to the fact that bananas and humans share a common ancestor from millions of years ago. While the DNA sequence may not be identical, there are enough similarities between the two species to result in a 50% genetic similarity. This is a fascinating example of the evolutionary relationships between different organisms.

Order of planets from the Sun:Mercury________EarthMarsJupiterSaturnUranusNeptune

Correct Answer
Venus

Explanation
The given order of planets from the Sun is Mercury, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, and Venus. This order follows the sequence of planets starting from the closest to the Sun (Mercury) and ending with the farthest (Venus). The answer, Venus, is the last planet in this sequence, making it the correct answer.

How many protons in Hydrogen?
- A.
  
  5
- B.
  
  3
- C.
  
  1
- D.
  
  2
Correct Answer
C. 1

Explanation
Hydrogen has one proton in its nucleus. This is the atomic number of hydrogen, which determines its chemical properties. Therefore, the correct answer is 1.

7.

What is not a type of quark?
- A.
  
  Up
- B.
  
  Down
- C.
  
  Strange
- D.
  
  Normal
Correct Answer
D. Normal

Explanation
The given options represent different types of quarks. Up, down, and strange are all types of quarks, but "normal" is not a recognized type of quark. Quarks are elementary particles and are categorized into different types based on their properties, such as their electric charge and mass. "Normal" is not a term used to describe any known type of quark in particle physics.

Rate this question:
8.

DNA has a _______ _______ structure

Correct Answer
double helix

Explanation
The correct answer is "double helix" because DNA, or deoxyribonucleic acid, is a molecule that consists of two long strands that are twisted around each other in a spiral shape, forming a structure that resembles a twisted ladder. This structure is known as a double helix. The two strands are held together by hydrogen bonds between complementary nucleotide bases, adenine (A) with thymine (T), and cytosine (C) with guanine (G). This unique structure allows DNA to store and transmit genetic information.

Rate this question:
9.

An isotope is a new element with a different amount of protons
- A.
  
  True
- B.
  
  False
Correct Answer
B. False

Explanation
An isotope is an element with the same number of protons but a different number of neutrons
