- C.
  
  Development of the cell theory by Matthias Schleiden and Theodor Schwann
Correct Answer
B. Antoni van Leeuwenhoek discovered various cells in various organisms.

Explanation
The advancements in glass lenses that allowed them to magnify up to 270 times resulted in Antoni van Leeuwenhoek's discovery of various cells in various organisms. With the improved magnification capabilities, van Leeuwenhoek was able to observe and describe microscopic organisms, including bacteria and protozoa, for the first time. This discovery contributed to the development of the cell theory by Matthias Schleiden and Theodor Schwann, who further expanded upon the concept of cells as the basic unit of life.

Proteins are large molecules made up of a series of amino acids. What is their main function?
- A.
  
  Regulates the immune system
- B.
  
  Helps regulate body temperature
- C.
  
  Controls cell metabolism
Correct Answer
C. Controls cell metabolism

Explanation
Proteins play a crucial role in controlling cell metabolism. They act as enzymes, which are responsible for catalyzing various chemical reactions in cells. These reactions are essential for the breakdown of nutrients, synthesis of new molecules, and production of energy. Proteins also regulate the rate of these reactions, ensuring that they occur at the appropriate speed for proper cell function. Therefore, controlling cell metabolism is the main function of proteins.

Ernst Abbe invented what technique in 1873?
- A.
  
  Staining cells
- B.
  
  Oil immersion
- C.
  
  Dissecting
Correct Answer
B. Oil immersion

Explanation
In 1873, Ernst Abbe invented the technique of oil immersion. Oil immersion is a method used in microscopy where a drop of oil is placed between the objective lens and the specimen. This technique helps to increase the resolution and clarity of the image by reducing the refraction of light. By using oil immersion, the numerical aperture of the lens is increased, allowing for better visualization of fine details and improving the overall quality of the microscopic image.

What is the function of the lysosome?
- A.
  
  To link chemicals
- B.
  
  To provide a site for photosynthesis
- C.
  
  To use stored enzymes to dissolve substances in a cell
Correct Answer
C. To use stored enzymes to dissolve substances in a cell

Explanation
The lysosome is an organelle responsible for breaking down and digesting various substances in a cell. It contains enzymes that can break down proteins, carbohydrates, lipids, and other molecules. These enzymes are stored within the lysosome until they are needed to break down substances such as worn-out organelles, foreign particles, or cellular waste. Therefore, the function of the lysosome is to use these stored enzymes to dissolve substances in a cell.

Organic compounds are composed mainly of:
- A.
  
  Carbon, Hydrogen, Oxygen
- B.
  
  Carbon, Sodium, Hydrogen
- C.
  
  Carbon, Silicon, Oxygen
Correct Answer
A. Carbon, Hydrogen, Oxygen

Explanation
Organic compounds are composed mainly of carbon, hydrogen, and oxygen. This is because organic compounds are based on carbon atoms, which can form strong covalent bonds with other carbon atoms and other elements such as hydrogen and oxygen. Carbon serves as the backbone of organic molecules, while hydrogen and oxygen are commonly found in functional groups attached to the carbon skeleton. Sodium and silicon are not typically found in organic compounds, making the options containing these elements incorrect.

The cell membrane contains fats and proteins
- A.
  
  True
- B.
  
  False
Correct Answer
A. True

Explanation
The cell membrane is composed of a phospholipid bilayer, which consists of two layers of phospholipids. Phospholipids are a type of fat molecule that has a hydrophilic (water-loving) head and a hydrophobic (water-repelling) tail. These phospholipids form a barrier that separates the inside of the cell from its external environment. Additionally, the cell membrane also contains proteins that are embedded within the lipid bilayer or attached to its surface. These proteins have various functions, such as transporting molecules in and out of the cell, facilitating cell communication, and providing structural support. Therefore, the statement that the cell membrane contains fats and proteins is true.
