How Are Basalt Columns Formed?
when lava cools and contracts, causing it to crack into geometric shapes, a process called columnar jointing.
What is the smallest unit of life?
A cell
What is botany?
Botany is the branch of biology that deals with the study of plants, including their structure, properties, and biochemical processes.
What is ecology?
Ecology is the study of the relationships between living organisms and their environment, including both biotic (living) and abiotic (non-living) factors.
How is matter held together?
chemical bonds
How Are Craters Formed?
by the impact of asteroids, comets, or meteoroids, or by volcanic explosions or collapses
What organelle is responsible for protein synthesis?
Ribosomes.
What are the main branches of botany
The main branches include morphology/physiology, ecology, and systematics.
What are some examples of biotic and abiotic factors?
What different types of bonding exist, and how are they different
The primary types of chemical bonds are ionic, covalent, and metallic
How Are Diamonds Made
formed from carbon atoms bonded under extreme pressure and temperature
What is the function of the mitochondria? A: Powerhouse of the cell, producing energy
ATP
What is the role of plants in the environment?
Plants are crucial for oxygen production, carbon dioxide removal, and form the base of many food chains.
What are the different levels of ecological organization?
How do ionic and covalent bonds form?
Ionic bonds form through the complete transfer of electrons from a metal to a nonmetal, creating oppositely charged ions that attract, while covalent bonds form when atoms share electrons to achieve a stable electron configuration.
How Do We Know the Earth Is Round?
the round shape of the Earth's shadow during lunar eclipses, ships disappearing hull-first over the horizon, and the ability to circumnavigate the globe.
What is the role of the Golgi apparatus
Modifies, sorts, and packages proteins and lipids.
What are some important plant structures and their functions?
Roots anchor plants and absorb water and nutrients,
What is a food chain?
A sequence of organisms in which energy is transferred from one organism to another through feeding.
What is a chemical reaction?
a process where one or more substances (reactants) transform into one or more different substances
How Far Have We Gone into Space?
248,655 miles (400,171 kilometers)
What is the function of the cell membrane
Regulates the movement of substances in and out of the cell.
What are some examples of plant adaptations to different environments?
Desert plants have adaptations like thick, waxy leaves and deep roots to conserve water
What is a food web?
A network of interconnected food chains in an ecosystem.
How is a chemical change different from a physical change
chemical change results in the formation of new substances with different properties.
