Answer:
D. Northern, Southern
Explanation:
The Northern and Southern Hemispheres experience opposite seasons and different day lengths, no matter what time of year.
Answer:
True blue is a rare color in plants. There are some flowers with blue hues but foliage plants tend to be more gray or green than blue. Green- and gold-colored foliage plants are everywhere. This plant is considered the grandfather of all blue-leaved hostas, and its thick, rounded, corrugated blue leaves develop into a 4-foot-wide by 2-foot-tall clump.
Answer: crossing over allows for genetic variation
Explanation:
crossing over is the exchange of genes between two chromosomes which ends up resulting in non-identical chromatids that comprise the genetic material of gametes (sperm and eggs).
Basically crossing over makes the chromatids that are held together by a centromere, no longer identical to eachother which creates genetic variation.
Answer
The seasons of the year, location of low and high pressure systems and air temperature all affect when and where a jet stream travels. Jet streams form a border between hot and cold air.

Answer:
- Bird wings and dragonfly wings are both used for flight: Analogous structure
- Clams and snails both have similar muscle structure even though the muscles do different jobs: Homologous structure
- Human and giraffe necks both have 7 vertebrae because we are related: Homologous structure
- The flaps of a Venus flytrap have a similar makeup to oak leaves: Homologous structure
Explanation:
Analogous structures are similar structures that have the same or similar functions in unrelated organisms. Analogous structures aren't the result of evolutionary relationships among organisms (i.e., they were not inherited from a common ancestor). On the other hand, homologous structures are structures inherited from a common ancestor. Homologous structures may or may not have an identical function, but they are the result of evolutionary relationships among organisms and, therefore, they are genetically related.
