Question

1. tradescantia ohiensis, a plant also known as bluejacket and its relatives, t. subaspera have similar reproductive mechanisms but do not mate, as one species lives in sun while the other lives in shade. a. geographic isolation b. behavioral isolation c. temporal isolation 5. a type of isolation in which two populations with complex courtship displays or rituals become different enough that they no longer respond to the other’s actions. a. geographic isolation b. behavioral isolation c. temporal isolation 6. the american toad (anaxyrus americanus) and fowler’s toad (bufo fowleri) live in the same area. however, the american toad mates in early summer while fowler’s mates in late summer. a. geographic isolation b. behavioral isolation c. temporal isolation 7. the flashing pattern of the firefly (lampyridae) is used to attract the opposite sex. female fireflies only flash back and attract male fireflies who first signal them with a species - specific pattern of light. a. geographic isolation b. behavioral isolation c. temporal isolation 8. a type of isolation where two species whose ranges overlap have different periods of sexual activity or breeding seasons. a. geographic isolation b. behavioral isolation c. temporal isolation 9. albert’s squirrel and the kaibab squirrel are distinct subspecies that live on opposite sides of the grand canyon. they were once one species, but now differ significantly, including fur coloring. a. geographic isolation b. behavioral isolation c. temporal isolation 10. of the seven species of cicada, (cicadae), three follow a 17 - year mating cycle, while four follow a 13 - year cycle. in regions where their geographic range overlaps, their emergence coincides once in every 221 years. this last happened in north america in 2015 and will not occur again until the year 2230. a. geographic isolation b. behavioral isolation c. temporal isolation

Explanation:

1. Since one species lives in sun and the other in shade (different habitats), it's geographic isolation.
2. Complex courtship displays becoming different is a behavioral trait, so it's behavioral isolation.
3. Different mating times (early summer vs late - summer) indicate temporal isolation.
4. Female fireflies responding only to a species - specific light pattern is a behavior, so it's behavioral isolation.
5. Different periods of sexual activity or breeding seasons mean temporal isolation.
6. Living on opposite sides of the Grand Canyon (separated by geography) is geographic isolation.
7. Different mating cycles (17 - year and 13 - year) with rare coincidences mean temporal isolation.

5. c. temporal isolation
6. a. geographic isolation
7. c. temporal isolation
