Understanding Key Biological Concepts

These flashcards cover key concepts related to biological processes, the behavior of water, and the implications of pH levels in various contexts.

Buffers

Substances that help maintain pH levels within a normal range.

Sodium Chloride Dissociation

The process by which sodium chloride separates into sodium and chloride ions in water.

Photosynthesis and Radioactive Carbon

Melvin Calvin used radioactive carbon as a tracer to study the molecules formed during photosynthesis.

Properties of Water

Characteristics of water that influence its behavior, such as cohesion, adhesion, and temperature regulation.

Antacids

Over-the-counter medications that alleviate heartburn by neutralizing excess H+ ions in the stomach.

H+ Ions

Hydrogen ions that increase the acidity of a solution, contributing to conditions such as heartburn.

Potential Changes on Mars

Environmental alterations that may have impacted water on Mars, affecting the ability for life to exist.
