Answer:
Vector
Explanation:
<u>Diseases can be transmitted by the mechanical or the biological vector. Vector is an animal (typically can be called as an arthropod) which carries disease from one host to another. </u>
Mechanical transmission is the one in which an animal which carries the pathogen from on host body to the another without being infected by it. It is facilitated by the mechanical vector.
Biological transmission is th eone which occurs when pathogen reproduces within the biological vector which transmits pathogen from one host body to the another.

Answer:
Earth's tilted axis causes the seasons. Throughout the year, different parts of Earth receive the Sun's most direct rays. So, when the North Pole tilts toward the Sun, it's summer in the Northern Hemisphere. And when the South Pole tilts toward the Sun, it's winter in the Northern Hemisphere.

Explanation:
Here, speciation occurs because the original butterfly population gets separated into two populations, each facing a different set of environmental conditions. Initially, there was just a single population of butterflies in the valley and all butterflies were able to mate with each other. A fire destroyed their habitat so they had to migrate to other areas. Some butterflies migrated to eastern side of mountain and some to western side of mountain.
Now there were two butterfly populations and they faced different environment from each other. Over the time, the populations adapted to their local surroundings and started to accumulate changes in their genome. Their gene pools started to separate from each other. Eventually they evolved into two different species. When their old habitat was restored in the valley, they returned once again. However, this time they were not able to interbreed because they were now two different species.
