Cells & Macromolecules
This organelle is responsible for making energy for a cell.
mitochondria
This process converts light energy into chemical energy in plants.
Photosynthesis
Different forms of the same gene are called these.
Alleles
This process explains how organisms with beneficial traits survive and reproduce more successfully.
Natural Selection
Organisms that make their own food are called these.
Autotrophs, producers
This macromolecule provides quick energy.
Give an example.
Carbohydrates
starch, sugar
This process releases energy from glucose to make ATP.
Cellular Respiration
A change in DNA sequence is called this.
Mutation
A trait that improves survival and reproduction is called this.
Adaptation
This type of symbiotic relationship has one organism benefiting and the other being unaffected.
Commensalism
This structure controls what enters and exits the cell.
Cell membrane
This is the movement of water across a selectively permeable membrane.
Osmosis
The observable traits of an organism are known as this.
Phenotype
These are parts of a body that are no longer used or needed.
Vestigal Structures
Organisms that break down dead matter and recycle nutrients are called these.
Decomposer
This organelle synthesizes proteins.
Ribosomes
Particles move from high concentration to low concentration during this process.
Diffusion
This type of cell division produces gametes.
Meiosis
A scientist discovers a population of bacteria that survives an antibiotic treatment. Why did some bacteria survived?
Some bacteria were already resistant to the antibiotics, then survived and reproduced.
This term describes the variety of life in an ecosystem.
Biodiversity
This macromolecule contains the instructions for building proteins and storing genetic information.
Give an example.
Nucleic Acids
DNA, RNA
If an enzyme becomes too hot and changes shape, this has occurred.
Denaturation
These are the TWO processes that are responsible for DNA --> RNA --> Proteins
Transcription
Translation
The forelimbs of whales, bats, cats, and humans have similar bone structures even though they serve different functions. These are examples of:
Homologous Structures
If predators are removed from an ecosystem, this population will most likely increase first.
Prey population
