Ecology
This type of survivorship curve is characterized by few but long-lived offspring.
What is a type I survivorship curve?
This is the process that is often referred to as 'survival of the fittest'.
What is natural selection?
This organelle produces energy from sugars using the citric acid cycle and oxidative phosphorylation.
What is the mitochondrion?
This organelle turns sunlight into sugar through the light-reactions and light-independent-reactions.
What is the chloroplast?
In RNA, adenine pairs with this nucleotide base.
What is uracil?
This form of succession would come after a light disturbance, like a low-intensity fire or storm.
What is secondary succession?
These are structures that share origins, but may not share functions.
What are homologous structures?
This organelle translates mRNA into proteins.
What is the ribosome?
This organelle houses the DNA.
What is the nucleus?
Three nucleotides in a row make up this amino-acid-coding unit.
What is a codon?
What is 'uniform'?
This effect explains why some populations that are geographically isolated may have abnormally high rates of certain alleles compared to other populations.
What is 'the founder effect'?
This organelle surrounds animal cells and controls the passage of substances.
What is the plasma membrane?
This organelle, not present in animal cells, keeps a cell rigid and provides an extra layer of protection.
What is a cell wall?
This protein structure refers to the sequence of the amino acids.
What is the primary structure of a protein?
This method of population approximation involves marking subjects to show they have been caught before.
What is 'mark-and-recapture'?
This is an example of density-dependent regulation.
What is resource availability/disease/predation?
This organelle transports newly made proteins and lipids to where they need to be.
What is the golgi apparatus?
This large organelle is present in plant cells, and stores water and other soluble cell products.
What is a large central vacuole?
This is a binding site on the DNA that controls the expression of a particular gene.
What is a promoter (or operator)?
This explains why each ecological niche is -- eventually -- only occupied by ONE species.
What is competitive exclusion?
This process is how mitochondria incorporated themselves into cells early on.
What is endosymbiosis?
This organelle is found only in plant cells, and connects two adjacent cells through their cell walls.
What are plasmodesmata?
These organelles are mainly present in plants, and stores colored substances that can prevent sun damage.
What are plastids?
These are the amino acids that the DNA strands 'GCT' and 'TCC' would code for.
What is 'Arg' (arginine)?
