5 Multiple choice questions
- entire set of genetic information that an organism carries in its DNA
- single-celled organisms that do not have a membrane-bound nucleus
- 1. Stores information in a stable form: The genome of every organism stores information that provides a blueprint to create its characteristics.
2. Provides continuity from generation to generation: The genome is copied and transmitted from generation to generation.
3. Acts as an instrument of evolutionary change: Every now and then, the genome undergoes a mutation that may alter the characteristics of an organism. In addition, a genome may acquire new genes by horizontal gene transfer. The accumulation of such changes from generation to generation produces the evolutionary changes that alter species and produce new species.
- Proteins facilitate the uptake and export of substances. Protein molecules that help to transport substances throughout the body and across cell membranes
5 True/False questions
Vertical Descent with Mutation → 1. Progression of changes in a lineage
2. New species evolve from preexisting species by the accumulation of mutations
3. Natural selection takes advantage of beneficial mutations
Cell Signaling (Proteomes) → Proteins are needed for cell signaling with other cells and with the environment. The molecular mechanisms by which cells detect and respond to external stimuli and send messages to other cells
Extracellular Proteins (Proteomes) → Proteins hold cells together in tissues.
Taxonomic Group → the group that does not receive the experimental treatment.
Hypothesis Example → 5 Stage Process
1. Observations are made regarding natural phenomena.
2. These observations lead to a hypothesis that tries to explain the phenomena. A useful hypothesis is one that is testable because it makes specific preditions.
3. Experimentation is conducted to determine if the predictions are correct.
4. The data from the experiment are analyzed.
5. The hypothesis is considered to be consistent with the data, or it is rejected.
