The 5 Phases of Mitosis
Mitosis is like construction workers in your body. It builds new cells they need to make more of themselves for healing or growth.
Life Science
Genetic Diversity – Advantages and Disadvantages
Genetic diversity is like having a toolbox with lots of different tools. In living things, these tools are the variations in genes.
What Are Chloroplasts: The Tiny Factories in Plants
What are chloroplasts? You’ll learn about their function, location, structure, and the process of photosynthesis within chloroplasts.
The 5 Classes of Vertebrates
Grouping animals into classes of vertebrates allows us to categorize the incredible diversity on Earth and their evolutionary histories.
Plant Tissue 101 – Types and Functions
Plants are composed of tissues, which are clusters of cells that work together to perform a function. Learn about plant tissue types & roles.
The Importance of Mangroves in Ecosystems
Mangroves are trees that grow in coastal areas where the land meets the sea. They have unique roots in saltwater and help protect erosion.
How Long Does It Take for Plastic to Decompose?
Plastic takes a really long time to decompose. For some items like plastic bottles and drinking straws, it can take hundreds of years.
What Are the 5 Koppen Climate Classification Types?
The Koppen climate classification catalogs Earth’s types of environments, which include tropical, dry, temperate, continental, and polar.
Taxonomic Classification: From Domain to Species
In biology, we categorize life by how similar organisms are with each other. Like a family tree, we find relationships by their classification of life.
What Are the 3 Domains of Life?
We categorize life into 3 domains of life: eukarya, archaea and bacteria. Domains classify life in the most general way such as the presence of a nucleus.
Cambrian Explosion: Life Diversification in the Oceans
The Cambrian explosion was the largest diversification of life in Earth’s history. Ocean life started as sparse and simple. Then, it remarkably diversified.
Cellular Respiration Steps: Energy Conversion in the Body
The single-most important biochemical reaction human beings need is cellular respiration. Our cells require oxygen to break down the food and provide energy.
What Are the 4 Levels of the Food Chain?
All living things rely on each other in the food chain. Energy transfers through living organisms from predators, herbivores, producers and decomposers.
The Biosphere: Life on Earth
The biosphere is the layer of Earth where life exists. You, me, plants, insects bacteria and all living things on land, air and oceans are the biosphere.
Nutrient Cycle: From Inorganic to Organic Material
Food for thought, the nutrient cycle constantly exchanges inorganic and organic matter back and forth in the environment. It’s just recycled back and forth.
