UNIT 1- Intro to Biology
These are the four basic requirements for something to be considered alive.
What are cells, energy use, growth & development, and reproduction?
Biomes are classified mainly by these two factors.
What are temperature and precipitation?
Organisms without a nucleus or membrane-bound organelles
What are prokaryotes?
he three types of body symmetry.
What are asymmetry, radial symmetry, and bilateral symmetry?
The smallest unit of matter that retains properties of an element.
What is an atom?
This type of metabolism builds complex molecules using energy.
What is anabolism?
This type of consumer eats producers directly.
What is a primary consumer?
The process bacteria use to reproduce asexually.
What is binary fission?
Arthropods with two body segments and eight legs.
What are arachnids?
The three particles in an atom and their charges.
What are protons (+), neutrons (0), and electrons (–)?
This type of organism makes its own food using sunlight or chemicals.
What is an autotroph?
This type of symbiosis benefits both organisms.
What is mutualism?
A virus that infects bacteria.
What is a bacteriophage?
Animals with a backbone and a closed circulatory system.
What are vertebrates?
The movement of water across a semi-permeable membrane.
What is osmosis?
These organisms break down dead matter and recycle nutrients back into the ecosystem.
What are decomposers?
The total dry mass of organisms in an area is known as this.
What is biomass?
The viral cycle where the virus stays dormant in the host DNA.
What is the lysogenic cycle?
The difference between open and closed circulatory systems.
What is open systems bathe organs in hemolymph and closed systems keep blood in vessels?
The four major biological macromolecules.
What are carbohydrates, lipids, proteins, and nucleic acids?
This is the process plants use to make glucose, represented by the equation
6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂.
What is photosynthesis?
The process by which plants release water vapor into the atmosphere.
What is transpiration?
The main reason viruses are not considered alive.
What is they cannot reproduce or carry out metabolism without a host?
Development with larval and adult stages including a pupa.
What is complete metamorphosis?
The balanced equation for photosynthesis.
What is 6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂?
