Semester 1 Storyline FINAL

Front

What cycle are fossil fuels part of?

Back

Carbon cycle: Fossil fuels are formed from the remains of ancient plants and animals, and their combustion releases carbon dioxide into the atmosphere, contributing to the carbon cycle.

Front

What is the accurate range for the pH scale?

Back

0-14: The pH scale measures the acidity or alkalinity of a solution, with 0 being very acidic, 7 neutral, and 14 very alkaline.

Front

What is diffusion?

Back

Diffusion is the process where molecules move from an area of high concentration to an area of low concentration without the use of energy.

Front

What macromolecules are responsible for storing long-term energy as fat?

Back

Lipids: These are organic compounds that include fats, oils, and waxes, and they store energy efficiently.

Front

What happens to herbivore populations after a wildfire destroys plant life?

Back

Herbivores would decrease due to a lack of food, as their primary food source (plants) is destroyed.

Front

Define active transport.

Back

Active transport is the movement of molecules across a cell membrane from a region of lower concentration to a region of higher concentration, requiring energy.

Front

What is the role of carbohydrates in living organisms?

Back

Carbohydrates provide energy and serve as structural components in cells.

Front

Explain the nitrogen cycle.

Back

The nitrogen cycle is the process by which nitrogen is converted between its various chemical forms, including fixation, nitrification, and denitrification.

Front

What is the significance of the water cycle?

Back

The water cycle is crucial for maintaining ecosystems, regulating climate, and supporting life by cycling water through evaporation, condensation, and precipitation.

Front

What are proteins made of?

Back

Proteins are made of amino acids, which are linked together by peptide bonds.
