Q: Answer the following question given this paragraph: in color. Golden algae are found in both freshwater and marine environments, where they form a major part of the plankton community. The brown algae are primarily marine, multicellular organisms that are known colloquially as seaweeds. Giant kelps are a type of brown algae. Some brown algae have evolved specialized tissues that resemble terrestrial plants, with root-like holdfasts, stem-like stipes, and leaf-like blades that are capable of photosynthesis. The stipes of giant kelps are enormous, extending in some cases for 60 meters. A variety of algal life cycles exists, but the most complex is alternation of generations, in which both haploid and diploid stages involve multicellularity. Compare this life cycle to that of humans, for instance. Haploid gametes produced by meiosis (sperm and egg) combine in fertilization to generate a diploid zygote that undergoes many rounds of mitosis to produce a multicellular embryo and then a fetus. However, the individual sperm and egg themselves never become multicellular beings. Terrestrial plants also have evolved alternation of generations. In the brown algae genus Laminaria, haploid spores develop into multicellular gametophytes, which produce haploid gametes that combine to produce diploid organisms that then become multicellular organisms with a different structure from the haploid form (Figure 23.19). Certain other organisms perform alternation of generations in which both the haploid and diploid forms look the same. Q: Some marine algae have evolved special structures capable of what plant process? A:

Answer the following question given this paragraph: Is Ceres a planet? Ceres only has about 1.3% of the mass of the Earth's Moon. Its orbit is full of other smaller bodies. Its gravity was not high enough to clear its orbit. Ceres fails the fourth criterion for being a planet. Ceres is now considered a dwarf planet, the closest to the Sun. Q: What kind of planet do we consider ceres to be? A:

OPTIONS:
- binary planet
- minor planet
- gas planet
- dwarf planet

Answer: dwarf planet

Problem: OPTIONS:
- amino acids
- enzymes
- steroids
- phospholipids
Q: Answer the following question given this paragraph: Plasma membranes are primarily made up of phospholipids (orange). The hydrophilic ("water-loving") head and two hydrophobic ("water-hating") tails are shown. The phospholipids form a bilayer (two layers). The middle of the bilayer is an area without water. There can be water on either side of the bilayer. There are many proteins throughout the membrane. Q: What substances that primarily comprise plasma membranes form a bilayer? A:
Answer: phospholipids

Problem:OPTIONS:
- kinetic energy
- mechanical energy
- stored energy
- potential energy

Answer the following question given this paragraph: The diver has energy because of her position high above the pool. The type of energy she has is called potential energy. Potential energy is energy that is stored in a person or object. Often, the person or object has potential energy because of its position or shape. Q: What energy is stored in a person or object? A:
****
A: potential energy

Problem:OPTIONS:
- conductivity
