Front

What is a deletion mutation?

Back

A deletion mutation is a type of genetic mutation where one or more nucleotides are removed from a DNA sequence, potentially altering the function of the resulting protein.

Front

What is the primary function of the digestive system?

Back

The digestive system breaks down complex nutrients into simpler forms that can be absorbed and utilized by the body.

Front

What is the role of the skeletal system?

Back

The skeletal system provides structure and support for the body, protects internal organs, stores minerals, and produces blood cells in the bone marrow.

Front

How many complete sets of DNA are present after the S phase of the cell cycle?

Back

After the S phase, there are 2 complete sets of DNA, as DNA replication occurs during this phase.

Front

What system responds to stimuli from inside and outside the body?

Back

The nervous system responds to stimuli from both internal and external environments, coordinating bodily functions and reactions.

Front

What is a substitution mutation?

Back

A substitution mutation is a type of genetic mutation where one nucleotide is replaced by another, potentially altering the amino acid sequence of a protein.

Front

What is the function of bacteria in the digestive system?

Back

Bacteria in the intestines help break down complex nutrients, aiding in digestion and nutrient absorption.

Front

What are the main components of the skeletal system?

Back

The main components of the skeletal system include bones, cartilage, ligaments, and joints.

Front

What is the significance of the S phase in the cell cycle?

Back

The S phase is significant because it is the stage where DNA replication occurs, resulting in two complete sets of chromosomes.

Front

What is the primary function of the circulatory system?

Back

The circulatory system is responsible for transporting blood, nutrients, gases, and waste products throughout the body.
