What is the name of the process by which cancer cells break off of tumors and spread to other parts of the body?

3. State the name and structure of the functional group for each type of biologically

A chemical reaction involving the transfer of electrons rather than molecules is classified as a Redox reaction. A reaction involving the loss of electrons is called Oxidation, and a reaction involving the gain of electrons is called Reduction. Oxidation and Reduction always occur together, as one reactant loses electrons, and the other gains them. This exchange often effects the physical states of molecules, as their solubility is changed with their charge.

Fever, swelling around initial infection site, parasites in blood, sometimes asymptomatic, rarely debilitating or life threatening problems can occur.

The cephalopodor octopus is a marine organism that inhabits many diverse regions of the ocean. Its food source consists of crabs, small fish, clams, mussels and other marine animals. The octopus is a predatory animal and has developed many skills to aid in its survival in the environment it has adapted to.

(d.) Biologists agree that there is sufficient evidence to concede to the sexual selection hypothesis and that the food competition hypothesis needs further testing.

7. Find two examples of convergent evolution among the Caminalcules. This means finding cases where two or more species have a similar characteristic that evolved independently in each lineage. The wings of bats, birds and bees is an example of convergence since the three groups did not inherit the characteristic from their common ancestor. Write your answers in complete sentences (e.g. “Species x and y both have ____ but their most recent common ancestor, z, did not”).

The purpose of this study is to identify four unknown organisms. The unknown organisms have been assigned randomly to six-research groups by Professor Hoffman. Each research group was provided two eukaryotes and two prokaryotes. The unknown organisms will fall into the following classifications: bacteria, algae, fungi, or protozoans. All living organisms are organized into one of three domains of life, Bacteria, Archaea, and Eukarya.
