control

(1) Xavier is studying birds in a forest preserve in Will County, Illinois. He goes out on a day to take a survey of bird species and out of 127 birds he finds, they are all either Robins or Blue Jays.

descent from a common ancestor; adaptation through natural selection

(1) The inability for a pile of cells to become living tissue is a feature of

(1) Regulation of molecules within an organism in response to a changing level of chemicals and the ability to self-regulate is called:

feedback regulation

(1) A nonlinear, realistic model the scientific process is called the process of science. The core activity of this process is:

forming and testing hypotheses

(1) In regulation of sperm production in the human male, sperm present in the testes cause the secretion of the hormone Inhibin. Inhibin triggers the hypothalamus in the brain to reduce production of the hormones GNRH, FSH, and LH; all of which stimulate sperm production. If the sperm count falls below 20 million cells per milliliter the quantity of Inhibin drops and sperm production resumes. This is an example of what system?

negative feedback regulation

reductionism

some conceivable observation or experiment could reveal whether a gven hypothesis is incorrect

(1) The energy used by most organisms for metabolism and growth ultimately comes from:

the sun

(1) The information in a gene that directs the production of a cellular product is gene expression. The correct sequence for the transfer of information from a gene to a function protein is:

transcription, translation, and protein folding
