A:
output: proteins

Answer the following question given this paragraph: Common acids and the polyatomic anions derived from them have their own names and rules for nomenclature. The nomenclature of acids differentiates between oxoacids, in which the H+ ion is attached to an oxygen atom of a polyatomic ion, and acids in which the H + ion is attached to another element. Carboxylic acids are an important class of organic acids. Ammonia is an important base, as are its organic derivatives, the amines. Q: What class of acids do carboxylic acids fall under? A:

OPTIONS:
- hydrochloric acids
- inorganic acids
- carbolic acids
- organic acids

Answer: organic acids

Problem: OPTIONS:
- pollen
- protists
- algae
- bacteria
Q: Answer the following question given this paragraph: Break down some substances in food that cannot be digested, such as fiber and some starches and sugars. Bacteria produce enzymes that digest carbohydrates in plant cell walls. Most of the nutritional value of plant material would be wasted without these bacteria. These help us digest plant foods like spinach. Q: What produces enzymes that digest carbohydrates in plant cell walls? A:
Answer: bacteria

Problem:OPTIONS:
- crescent
- new moon
- blue moon
- full moon

Answer the following question given this paragraph: The Earth, Moon and Sun are linked together in space. Monthly or daily cycles continually remind us of these links. Every month, you can see the Moon change. This is due to where it is relative to the Sun and Earth. In one phase, the Moon is brightly illuminated - a full moon. In the opposite phase it is completely dark - a new moon. In between, it is partially lit up. When the Moon is in just the right position, it causes an eclipse. The daily tides are another reminder of the Moon and Sun. They are caused by the pull of the Moon and the Sun on the Earth. Tides were discussed in the Oceans chapter. Q: In what phase is the moon brightly illuminated? A:
****
A: full moon

Answer the following question given this paragraph: Oxygen has an oxidation state of -2 in most of its compounds. Oxygen is the second most electronegative element, so it also tends to be assigned all shared electrons. Exceptions include O 2 (oxidation state = 0), peroxides, in which two oxygen atoms are connected by a single bond (oxidation state usually = -1), and any compound in which oxygen is bonded to fluorine (pretty rare and reactive). Q: What is the name of the second most electronegative element? A:
OPTIONS:
- nitrogen
- Hydrogen
- carbon
- oxygen
oxygen

Answer the following question given this paragraph: Watch this video (http://openstaxcollege. org/l/symmetry2) to see a quick sketch of the different types of body symmetry. Layers of Tissues Most animal species undergo a layering of early tissues during embryonic development. These layers are called germ layers. Each layer develops into a specific set of tissues and organs. Animals develop either two or three embryonic germs layers (Figure 15.5). The animals that display radial symmetry develop two germ layers, an inner layer (endoderm) and an outer layer (ectoderm). These animals are called diploblasts. Animals with bilateral symmetry develop three germ layers: an inner layer (endoderm), an outer layer (ectoderm), and a middle layer (mesoderm). Animals with three germ layers are called triploblasts. Q: What term is used to describe animals with three germ layers? A:
OPTIONS:
- sporozoans
- triplegerm
- multilayer
- triploblasts

Answer:
triploblasts
