Characteristics of Life
The building blocks of organisms.
What are cells?
This type of cell does not have a nucleus.
What is a prokaryotic cell/prokaryote?
A change in DNA.
What is a mutation?
Change in a population over time.
What is evolution?
Rocks, temperature, air currents, water.
What is abiotic?
The ability for an organism to make copies of itself.
What is reproduction?
Cell wall, chloroplasts and large vacuole.
What are organelles found in plant and not animal cells?
The different versions of a gene.
What is an allele?
A group of the organisms that and can reproduce with one another.
What is a species?
This biome is found on all continents except Antarctica, has frequent fires, large herbivores, and few trees.
What is a grassland/savanna?
When an organism gets bigger or changes its form.
What is growth and development?
The movement of water molecules across a semipermeable membrane from an area of high concentration to low concentration.
What is osmosis?
What is phenotype?
A trait (structural or behavioral) that allows an organism to survive better in its environment.
What is an adaptation?
Multiple different species living in the same area interacting with each other and their nonliving environment.
What is an ecosystem?
The ability of an organism to regulate its internal conditions.
This type of cell division makes cells for growth, development and repair. Two identical cells are made.
What is mitosis?
Represented by one uppercase letter and one lowercase letter.
What is a heterozygous genotype?
The process in which organisms with traits better suited to the environment have a better chance of surviving, reproducing, and passing on their genetic information.
What is natural selection?
The amount of of organisms that can be supported by the resources in a given area.
What is carrying capacity?
A change in an organisms environment that leads to a reaction.
What is a stimulus/stimuli?
C6H12O6 + 6O2 --> 6CO2 + 6H2O + ATP
What is the cellular respiration?
A long tightly coiled strand of DNA. Humans have 46 of them.
What is a chromosome?
All populations must have this in order to allow for evolution. It may be caused by mutations or meiosis.
What is genetic variation?
The terms to describe the two organisms involved in a symbiotic relationship where one benefits and the other is harmed.
What is host and parasite?
