Which of the following pairs of reproductive strategies is consistent with energetic trade-off and reproductive success? 

#Unit 10. Ecological Principles
  1. Pioneer species of plants produce many very small, highly airborne seeds, while large elephants that are very good parents produce many offspring.
  2. Female rabbits that suffer high predation rates may produce several litters per breeding season, and coconuts produce few fruits, but most survive when they encounter proper growing conditions.
  3. Species that have to broadcast to distant habitats tend to produce seeds with heavy protective seed coats, and animals that are caring parents produce fewer offspring with lower infant mortality.
  4. Free-living insects lay  thousands of  eggs  and  provide no  parental care, while  flowers take  good  care  of their seeds until they are ready to germinate.

#Unit 8. Inheritance Biology

Phenotypic variation that is due to genetic differences is referred to as heritability. It can be the Broad-sense heritability and Narrow-sense heritability, the Broad-sense heritability which is ranges from 0 to 1. Identify the correct prediction about these ranges?
a) 0 is all of the phenotypic variance results from differences in genotype
b) 0 is all of the phenotypic variance results from environmental variation
c) 1 is all of the phenotypic variance results from differences in genotype
d) 1 is all of the phenotypic variance results from environmental variation
