An environmental system made up of organisms interacting with one another and with nonliving factors to form a work unit.
Ecosystem
The gradual change in species over time
Evolution
Name one organelle that plants cells have but animal cells do not
Cell wall, Chloroplast, Large vacuole
During which phase of cell division are chromosomes separated?
Anaphase
What is made during translation?
proteins
The nonliving factors found in an ecosytem.
Abiotic factors
The process by which individuals that are better suited to the environment survive and reproduce therefore passing down their genes to their offspring?
Natural Selection
What are the products of cell respiration?
Carbon dioxide, water, and ATP
This is Darwin's term for homozygous
Purebred
Organisms that use dead organisms and the waste material of other organisms for food.
Decomposers
Genetic differences between organisms of the same species
variation
Name the location in a cell where DNA/chromosomes can be found.
nucleus
During which stage of meiosis do chromosomes cross over leading to genetic variation
metaphase 1
The bring the amino acids to the ribosome in the correct order to make the protein.
The things that limit the size of a population, such as the amount of rainfall or food.
Limiting factors
The reason more advantageous traits are more likely to be passed onto offspring.
The individuals with those traits are more likely to survive and reproduce
These organelles are the site of cell respiration
Mitochondria
How would you know if photosynthesis is occur when a plant is in a clear jar of water?
In terms of number and type of cells produced,
what is the result of meiosis?
what is the result of mitosis?
meiosis makes 4 genetically different, haploid gametes
mitosis makes 2 identical cells, diploid, somatic cells
Is it possible for two parents purebred for dimples to have an offspring with no dimples? (dimples is a complete dominant trait)
No
DD x DD
If there is a mutation in the DNA that changes the amino acid sequence, how does it affect the protein?
the protein would not be fully functioning
The role of an organism in an ecosystem.
Niche
Describes a pattern of long, stable periods interrupted by brief periods of more rapid change
Punctuated equilibrium
