For the following questions, mark "T" to indicate a TRUE statement, or "F" to indicate a FALSE statement
1. One important difference between eukaryotic and prokaryotic cells is that the former use DNA as the hereditary material while the latter do not.
2. A scientific theory is basically an unsupported 'best guess' at an explanation for a range of natural phenomena.
3. The process of mitosis produces offspring cells that are genetic clones (or near genetic clones) of one another.
4. The process of meiosis produces offspring cells that are genetic clones (or near genetic clones) of one another.
5. Genetic mutation can be considered a 'bad thing' because it always harms the functioning of an organism in its environment.
6. All living things form a single tree of life, i.e., they are all related by ancestry.
7. Humans and chimpanzees, being different species, share almost no genetic information (i.e., genes).
8. The primary test of truth for a scientific statement is the reputation of the scientist making it. The work of a great scientist does not need to be checked or challenged.
9. The process of replication of DNA molecules always produces perfect copies, i.e., new DNA molecules that are identical to the old ones.
10. 2 sexually-reproducing organisms are considered the same species only if opposite mating types (male/female) are capable of mating to produce viable, fertile offspring. Producing live offspring is not sufficient.
11. In humans and other mammals, meiosis takes place only in the ovaries (in females) and in the testes (in males), and not in other body organs.
12. A radioactive isotope (such as carbon-14) is inherently dangerous and so does not provide science with any useful functions.
13. Combustion reactions (burning) are endothermic, as can be perceived by the heat and light they give off.
14. Inanimate (non-living) things are made of atoms, just as living things are.
15. The cells of a multicellular organism (such as a human being) function as individuals. There is no need for communication or cooperation between them.
16. The plasma membrane of a cell is a very simple, smooth structure, similar to a balloon.
