Unit 2- Science of Life Review

Front

What is an organic molecule?

Back

An organic molecule is a compound that contains carbon and is found in living organisms. Example: Glucose (C6H12O6).

What characteristic of life explains why birds migrate?

Back

Adaptation to the environment explains why birds fly south in winter to find food and survive.

Front

What is the smallest level of organization in an organism?

Back

The smallest level of organization in an organism is a cell.

Front

What is a Positive Feedback Loop?

Back

A Positive Feedback Loop is a process where the output enhances or increases the original stimulus. Example: Oxytocin release during childbirth.

Front

What is homeostasis?

Back

Homeostasis is the process by which living organisms regulate their internal environment to maintain stable, constant conditions. Example: Regulation of body temperature in humans.

Front

What is the function of glucose in living organisms?

Back

Glucose serves as a primary energy source for cells and is essential for cellular respiration.

Front

What is the role of adaptation in evolution?

Back

Adaptation is a trait that helps an organism survive and reproduce in its environment, contributing to the process of evolution.

Front

What are the four main types of organic molecules?

Back

The four main types of organic molecules are carbohydrates, lipids, proteins, and nucleic acids.

Front

What is the difference between positive and negative feedback loops?

Back

Positive feedback loops amplify changes, while negative feedback loops counteract changes to maintain stability.

Front

What is cellular respiration?

Back

Cellular respiration is the process by which cells convert glucose and oxygen into energy, carbon dioxide, and water.
