- E.
  
  Rabbit Faeces
Correct Answer
D. Small finger like structures in the small intestine

Explanation
Villi are small finger-like structures in the small intestine. These structures increase the surface area of the intestine, allowing for better absorption of nutrients from digested food. They have a rich blood supply and are covered in microvilli, which further increase the surface area for absorption. Villi play a crucial role in the digestion and absorption of nutrients into the bloodstream.

Respiration happens in (what part of the cell)?

Correct Answer
Mitochondrian
Mitochondrion

Explanation
Respiration occurs in the mitochondria of the cell. The mitochondria are known as the powerhouse of the cell, as they are responsible for producing energy through the process of cellular respiration. This process involves the breakdown of glucose molecules to release energy in the form of ATP (adenosine triphosphate). The mitochondria have their own DNA and are capable of self-replication, which further supports their role in respiration. Therefore, the correct answer is mitochondria or mitochondrion.

In the periodic table, where are the atomic numbers of the elements placed in the box?
- A.
  
  Bottom right corner
- B.
  
  It varies
- C.
  
  Some where over the rainbow
- D.
  
  Top left corner
- E.
  
  Bottom left corner
Correct Answer
B. It varies

Explanation
The atomic numbers of the elements in the periodic table are not placed in a specific location within the box. Instead, they vary depending on the specific element. The atomic number represents the number of protons in an atom's nucleus, and it determines the element's position in the periodic table. Therefore, the atomic numbers can be found in different locations throughout the periodic table, depending on the element being represented.

What is Hydrogen Oxide?
- A.
  
  Water
- B.
  
  Kryptonium
- C.
  
  The basis of washing powder
- D.
  
  Salt
- E.
  
  The air we breathe
Correct Answer
A. Water

Explanation
Hydrogen oxide refers to water, which is a compound made up of two hydrogen atoms and one oxygen atom. It is commonly known as H2O and is essential for all forms of life. Water is a colorless, odorless, and tasteless liquid that exists in three states - solid (ice), liquid (water), and gas (water vapor). It is a vital solvent, plays a crucial role in various biological processes, and is essential for maintaining the Earth's climate and supporting ecosystems.

In a convection system,____ rises

Correct Answer
heat

Explanation
In a convection system, heat rises due to the principle of convection. Convection is the transfer of heat through the movement of a fluid, such as air or water. When a fluid is heated, it becomes less dense and rises, while the cooler, denser fluid sinks. This creates a cycle of rising and sinking motion, causing the heat to rise. As a result, convection is responsible for the circulation of heat in various systems, such as the Earth's atmosphere and the heating of a room through a radiator.

  299 792 458 miles per second?
- B.
  
  114 987 314 km per second?
- C.
  
  293 456 222 miles per hour?
- D.
  
  299 792 458 miles per minute?
- E.
  
  Fast
Correct Answer
A. 299 792 458 miles per second?

Explanation
Light travels at a speed of 299,792,458 miles per second. This is the correct answer because it accurately represents the speed of light in miles per second.

In order, the temperature of the human body, melting and boiling points of ethanol are: (celcius)
- A.
  
  37, 100 and 0
- B.
  
  35, 79, -114.3
- C.
  
  37, 70, -114.3
- D.
  
  Huh?
- E.
  
  38, 68, -10
Correct Answer
C. 37, 70, -114.3

Explanation
The correct answer is 37, 70, -114.3. The temperature of the human body is approximately 37 degrees Celsius. The melting point of ethanol is 70 degrees Celsius, meaning it changes from a solid to a liquid state at this temperature. The boiling point of ethanol is -114.3 degrees Celsius, indicating that it changes from a liquid to a gas state at this temperature.

Iodine is found in:
- A.
  
  Eggs
- B.
  
  Fish
- C.
  
  Meat
- D.
  
  Pasta
- E.
  
  Bread
Correct Answer
B. Fish

Explanation
Iodine is found in fish because fish absorb iodine from seawater and accumulate it in their tissues. This is why fish, especially saltwater fish, are considered a good source of iodine. Other sources of iodine include seaweed, dairy products, and iodized salt.

The heart can also be called a:
- A.
  
  Boum Chika boum
- B.
  
  Thingy that beats fast
- C.
  
  Double pump
- D.
  
  A weak organ (not very muscular)
- E.
  
  A muscular single pump
Correct Answer
C. Double pump

Explanation
The heart is referred to as a double pump because it consists of two separate pumps that work together to circulate blood throughout the body. The right side of the heart receives oxygen-depleted blood from the body and pumps it to the lungs to pick up oxygen. The left side of the heart receives oxygen-rich blood from the lungs and pumps it to the rest of the body. This dual pumping action allows for efficient oxygenation of the blood and ensures that oxygen is delivered to all the organs and tissues in the body.

The sun gets its energy by: (last one...hard one!)
- A.
  
  Turning air into light
- B.
  
  Absorbing light given out by stars
- C.
  
  Burning up oxygen
- D.
  
  Turning hydrogen into helium
- E.
  
  It doesnt need energy
Correct Answer
D. Turning hydrogen into helium

Explanation
The sun gets its energy by turning hydrogen into helium. This process, known as nuclear fusion, occurs in the sun's core where immense pressure and temperature cause hydrogen atoms to combine and form helium. This fusion reaction releases a tremendous amount of energy in the form of light and heat, which is what provides the sun with its energy.
