Science for 11th Graders Trivia Quiz

Answer: asexual

Asexual reproduction typically involves cell division by mitosis. Many plants use asexual reproduction as it is easier than finding a mate, for example strawberry plants and potatoes. Typical examples of asexual reproduction allow less opportunity for variation -- so if there was a change in the environment of the plant, it would not be able to adapt. (Some variation is possible for, say, plants that pollinate themselves -- although you still don't get as much variation as you would if there were two separate plants involved.)

Answer: Hydrogen

The Haber process is a reversible reaction. It uses hydrogen and nitrogen to produce ammonia (a very useful product) but the conditions must be right to get the best possible yield.

Answer: non-metals with non-metals

Non-metals react with non-metals when there are no metals around. They form covalent or double bonds where they share electrons to each believe they have full outer shells.

Answer: Saturn

Answer: Diffraction

Refraction is the bending of {light;} dispersion is the spreading out of light in prisms to form a {spectrum;} reflection is the change of direction of a wave when it hits a surface. (angle of incidence = angle of reflection)

Answer: Recessive

It is caused by a recessive allele which means you have to have both infected alleles to be a sufferer of the disease.

Answer: Fluorine

As you go down group seven, the elements get less reactive. This is because they have one more outer shell of electrons, so the attraction is less strong and cannot gain electrons from elsewhere as easily.
