Ecology & Evolution
Nonliving parts of an ecosystem
What are abiotic factors?
The process that makes identical daughter cells.
What is mitosis?
This molecule contains genetic instructions.
What is DNA?
A section of DNA that codes for a trait.
What is a gene?
Cancer occurs when cells lose control of this process.
What is cell growth and division?
The main source of energy in most ecosystems.
What is the Sun?
The process that happens in gametes.
What is meiosis?
Proteins/Polypeptide chains are made in this organelle.
What is a ribosome?
Gregor Mendel is known for experiments with this organism.
What are pea plants?
A substance that can cause cancer is called this.
What is a carcinogen?
The direction that arrows move in in a food web.
What is energy?
During this stage of mitosis, chromosomes line up in the middle of the cell.
What is metaphase?
The process of making mRNA from DNA is called this.
What is transcription?
An organism that has both a dominant and recessive allele.
What is heterozygous?
Cancer spreading through the body is called this.
What is metastasis?
This process happens when organisms with favorable traits survive and reproduce more often.
What is natural selection?
Crossing over occurs during this stage of meiosis, leading to more genetic variation.
What is prophase I?
This type of RNA interprets mRNA for the ribosome to make amino acids.
What is tRNA?
Meiosis increases this in offspring.
What is genetic variation?
This process is programmed cell death.
What is apoptosis?
Ecological relationship that exists between leaf cutter ants.
What is cooperation?
When human gametes contain half as many chromosomes.
What is haploid?
Used to unzip DNA during replication
What is helicase?
A change in DNA that causes all base pairs downstream to move their codons in one direction or another.
What is a frameshift mutation?
Chemotherapy especially harms these types of cells.
What are rapidly dividing cells?
