Multiple choice

What is the function of the eardrum?

  1. Transmitting sound waves to the inner ear

  2. Maintaining balance

  3. Producing earwax

  4. Protecting the ear from foreign objects
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The eardrum, or tympanic membrane, vibrates when sound waves hit it, transmitting these vibrations to the ossicles in the middle ear.

Multiple choice

What is the function of the ossicles?

  1. Amplifying sound waves

  2. Transmitting sound waves to the inner ear

  3. Maintaining balance

  4. Protecting the ear from foreign objects
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The ossicles, a chain of three small bones in the middle ear, transmit sound waves from the eardrum to the inner ear.

Multiple choice

What is the role of the auditory nerve?

  1. Transmitting electrical signals from the cochlea to the brain

  2. Maintaining balance

  3. Producing earwax

  4. Protecting the ear from foreign objects
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The auditory nerve transmits electrical signals generated in the cochlea to the brain, where they are interpreted as sound.

Multiple choice

What is the primary function of carbohydrates in the body?

  1. To provide energy

  2. To build and repair tissues

  3. To regulate body temperature

  4. To help absorb vitamins and minerals
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Carbohydrates are the body's primary source of energy. They are broken down into glucose, which is then used by cells for energy production.

Multiple choice

What is the primary function of proteins in the body?

  1. To provide energy

  2. To build and repair tissues

  3. To regulate body temperature

  4. To help absorb vitamins and minerals
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Proteins are essential for building and repairing tissues, including muscles, bones, skin, and organs. They also play a role in enzyme production, hormone regulation, and immune function.

Multiple choice

What is the purpose of cell disruption in downstream processing?

  1. To release the intracellular contents of the cells.

  2. To improve the efficiency of downstream processing operations.

  3. To reduce the viscosity of the cell suspension.

  4. To facilitate the removal of impurities.
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Cell disruption is employed to break open the cells and release their intracellular contents, which may contain the desired product or other valuable biomolecules.

Multiple choice

What is the primary function of carbohydrates in the body?

  1. Building and repairing tissues

  2. Storing energy

  3. Regulating body temperature

  4. Producing hormones
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Carbohydrates are the body's main source of energy. They are broken down into glucose, which is then used by cells for fuel. Carbohydrates can also be stored in the liver and muscles as glycogen for later use.
