Q1 Biology Level Up (Part 2) Quiz Version

What is the main function of carbohydrates?

• To store genetic material

• Form important structures, regulate cell processes, fight diseases

• Storage of energy and chemical messengers

• Storage and release of energy, strucrure, and support

Answer explanation

Carbohydrates primarily function in the storage and release of energy, as well as providing structure and support to cells. This makes the correct choice "Storage and release of energy, structure, and support."

What is one similarity between prokaryotic and eukaryotic cells?

• They both have membrane bound organelles.

• They both have a nucleus.

• They both use ribosomes.

• They both have DNA within the nucleus.

Answer explanation

Both prokaryotic and eukaryotic cells use ribosomes for protein synthesis, which is a fundamental similarity. However, prokaryotic cells lack membrane-bound organelles and a nucleus, unlike eukaryotic cells.

Which of the following organelles are specific to the plant cell?

• Lysosomes, Mitochondria, and Large Central Vacuole

• Centrioles, Cell Wall, and Golgi Apparatus

• Mitochondria, Chloroplast, and Plasma Membrane

• Chloroplast, Cell Wall, and Large Central Vacuole

Answer explanation

The correct choice is Chloroplast, Cell Wall, and Large Central Vacuole, as these organelles are unique to plant cells. Chloroplasts are involved in photosynthesis, the cell wall provides structure, and the large central vacuole stores nutrients.

Cell Theory States the following (Select all that apply)

• All cells come from spontaneous generation

• Cells are the basic unit of life

• All cells come from pre-existing cells

• All living things are made up of cells

Answer explanation

Cell Theory states that cells are the basic unit of life, all living things are made up of cells, and all cells come from pre-existing cells. Spontaneous generation is not part of Cell Theory.

Which organelle contains digestive enzymes to

breakdown harmful substances or waste?

• Chloroplast

• Vacuole

• Lysosome

• Centriole

Answer explanation

The lysosome is the organelle that contains digestive enzymes specifically designed to break down harmful substances and waste within the cell, making it essential for cellular cleanup and maintenance.

What is one of the functions of lipids?

• Storing genetic information

• Long Term Energy

• Short Term Energy

• Acting as chemical signals

Answer explanation

Lipids are primarily used for long-term energy storage in the body. Unlike carbohydrates, which provide short-term energy, lipids store energy more efficiently, making them essential for sustained energy needs.

The diagram shows the general structure of an amino acid. Which type of molecule is formed from amino acids?

• lipids

• proteins

• carbohydrates

• nucleic acids

Answer explanation

Amino acids are the building blocks of proteins. When linked together through peptide bonds, they form polypeptides, which then fold into functional proteins. Therefore, the correct answer is proteins.

Which of the following is a possible result of a disruption in the cell cycle?

• cancer

• photosynthesis

• cellular respiration

• protein synthesis

Answer explanation

A disruption in the cell cycle can lead to uncontrolled cell division, which is a hallmark of cancer. The other options, such as photosynthesis and cellular respiration, are metabolic processes not directly linked to cell cycle disruptions.

A well-tested explanation that explains a lot of observations and is supported by lots of evidence

• a hypothesis

• an inference

• a theory

• a controlled experiment

Answer explanation

A theory is a well-tested explanation that accounts for a wide range of observations and is supported by substantial evidence, distinguishing it from a hypothesis, which is a preliminary idea.
