A genetic inheritance pattern that results from the fact that certain alleles seem to be coded differently according to which parent that come from.

  1. Epistasis
  2. Epigenesis
  3. Genomic imprinting
  4. Triplet repeat extension
  5. Mitochondrial inheritance

Answer(s): C

Explanation:

Genomic imprinting is the situation in which certain alleles seem to be methylated in different patterns depending upon which parent they come from. Thus, an allele for a certain trait coming from the father's sperm may not be expressed in the offspring at all, even though the identical allele from the mother's egg would be expressed.



The driest of all biomes, with little rain and limited vegetation.

  1. Taiga
  2. Temperate deciduous forest
  3. Tundra
  4. Chaparral
  5. Desert

Answer(s): E

Explanation:

The driest of all biomes is the desert.



Characterized by an abundance of fire-resistant plants, this biome is found in coastal areas that experience long, hot summers and short, rainy winters.

  1. Taiga
  2. Temperate deciduous forest
  3. Tundra
  4. Chaparral
  5. Desert

Answer(s): D

Explanation:

The chaparral and savanna are two coastal biomes characterized by long, hot summers and short, rainy winters with fire- resistant plants than can quickly reseed the habitat after fires come through.



Known as the ''frozen desert," this biome experiences long, harsh winters and darkness for up to 10 months of the year.

  1. Taiga
  2. Temperate deciduous forest
  3. Tundra
  4. Chaparral
  5. Desert

Answer(s): C

Explanation:

The tundra, found in the upper and lower latitudes, is commonly called the "frozen desert," characterized by a layer of permanently frozen soil (permafrost) a few inches below the surface even during the warmer summer months.



BF. Skinner used his famous "Skinner boxes" to investigate this type of animal behavior involving a reward as reinorcement for an action.

  1. Fixed action pattern
  2. Imprinting
  3. Habituation
  4. Associative learning
  5. Operant conditioning

Answer(s): E

Explanation:

Skinner was known for his work with operant conditioning: the idea that behaviors can be increased in frequency with positive reinforcement (reward) or extinguished with negative reinforcement (e.g. a shock).
