Fox Tech Biology Fall Semester Review

Front

During which parts of the cell cycle does the cell grow?

Back

G1 and G2 are the phases of the cell cycle where the cell grows and prepares for DNA replication and mitosis.

Front

According to Chargaff's rules, if a cell contains 20% Guanine, how much Adenine will it contain?

Back

30%. Chargaff's rules state that %G = %C and %A = %T, so if G is 20%, A must be 30%.

Front

What is uncontrolled cell division that usually leads to tumors and disease called?

Back

Cancer is the term used for uncontrolled cell division that can lead to tumors and various diseases.

Front

Which two molecules contain the elements C-H-O and function pertains to energy?

Back

Carbohydrates and Lipids are the two molecules that contain carbon, hydrogen, and oxygen and are primarily involved in energy storage and supply.

Front

What do the arrows in a food chain diagram indicate?

Back

The arrows indicate the direction of energy flow through a series of organisms.

Front

What is the function of the G1 phase in the cell cycle?

Back

The G1 phase is responsible for cell growth and preparation for DNA synthesis.

Front

What is the role of nucleotides in genetics?

Back

Nucleotides are the building blocks of DNA and RNA, encoding genetic information.

Front

What is the significance of Chargaff's rules in DNA structure?

Back

Chargaff's rules explain the base pairing in DNA, where the amount of adenine equals thymine and the amount of guanine equals cytosine.

Front

What is the main difference between benign and malignant tumors?

Back

Benign tumors are non-cancerous and do not spread, while malignant tumors are cancerous and can invade nearby tissues.

Front

What are lipids primarily used for in biological systems?

Back

Lipids are primarily used for long-term energy storage, insulation, and making up cell membranes.
