Q: Answer the following question given this paragraph: There are three types of mammals, characterized by their method of reproduction. All mammals, except for a few, are viviparous , meaning they produce live young instead of laying eggs. The monotremes , however, have birdlike and reptilian characteristics, such as laying eggs and a cloaca. An example of a monotreme is the platypus with its birdlike beak and egg-laying characteristics. The echidnas are the only other monotreme mammals. A second type of mammal, the marsupial mammal, includes kangaroos, wallabies, koalas and possums. These mammals give birth to underdeveloped embryos, which then climb from the birth canal into a pouch on the front of the mother's body, where it feeds and continues to grow. The remainder of mammals, which is the majority of mammals, are placental mammals. These mammals develop in the mother's uterus, receiving nutrients across the placenta. Placental mammals include humans, rabbits, squirrels, whales, elephants, shrews, and armadillos. Dogs and cats, and sheep, cattle and horses are also placental mammals. Q: The three types of mammals are characterized by their method of what? A:

OPTIONS:
- specializaiton
- differentiation
- pattern

Answer the following question given this paragraph: There are 20 common amino acids in proteins. There are 64 possible codons, more than enough to code for the 20 amino acids. The genetic code is shown in Figure below . To see how scientists cracked the genetic code, go to this link: http://www. dnalc. org/view/16494-Animation-22-DNA-words-are-three-letters-long-. html . Q: Proteins include 20 common types of what compounds? A:

OPTIONS:
- mitochondria
- rna acids
- dna
- amino acids

Answer: amino acids

Problem: OPTIONS:
- extinction
- evolution
- re-population
- interbreeding
Q: Answer the following question given this paragraph: Assume that some members of a species become geographically separated from the rest of the species. If they remain separated long enough, they may evolve genetic differences. If the differences prevent them from interbreeding with members of the original species, they have evolved into a new species. Speciation that occurs in this way is called allopatric speciation . An example is described in the Figure below . Q: A new species is said to have evolved if separated members of a species evolve genetic differences that prevent what from occurring with the original members?? A:
Answer: interbreeding

Problem:OPTIONS:
- starches and water
- water and fiber
- fiber and minerals
- starches and fats

Answer the following question given this paragraph: Figure 16.5 (a) Digestion of food begins in the mouth. (b) Food is masticated by teeth and moistened by saliva secreted from the salivary glands. Enzymes in the saliva begin to digest starches and fats. With the help of the tongue, the resulting bolus is moved into the esophagus by swallowing. (credit: modification of work by Mariana Ruiz Villareal). Q: Enzymes in saliva help bread down and digest what? A:
****
A: starches and fats

Problem:OPTIONS:
- nebula
- solar systems
- galaxies
- dark matter

Answer the following question given this paragraph: We see many objects out in space that emit light. We see other objects that emit other types of electromagnetic radiation. The matter we can see is contained in stars. The stars are contained in galaxies. Scientists think that stars and galaxies make up only a small part of the matter in the Universe. The rest of the matter is called dark matter . Q: What is the area of our universe that isn't stars and galaxies called? A:
****
A:
dark matter
