Answer:
Convergent Evolution.
Explanation:
When two different species that are very distantly related but have similar traits its Convergent Evolution due to environmental pressures.
Answer:
Earth's surface didn't look much different. With few exceptions.
The global climate is cooler and drier, and seasonal, similar to modern climates. As the climate began to cool down grasslands continued to expand and forests started to dwindle in extent. In the seas, kelp forests made their first appearance and soon became one of Earth's most productive ecosystems. Water from the Atlantic Ocean poured in through the Strait of Gibraltar to deluge the Mediterranean Basin. The event is called the Zanclean flood. Parts of of southern Norway and southern Sweden that had been near sea level rose to form the Hardangervidda plateau and the South Swedish highlands.
Shorty after, the glaciations, uplift of the Rocky mountains and Panama seaway closure began to reshape the Earth.
Explanation:
Answer:
They difference in phenotypes is dependent on the genes. The more dominant gene will overpower a recessive gene, or if there are two recessive genes together, that will be the phenotype. When things are cross breaded they introduce different genotypes that allow for different looking phenotypes.
Example: Dominant blue flower (Bb) mixed with recessive yellow flower (bb)
B b
b Bb bb
b Bb bb
There is a 50/50 chance the offspring will be either blue or yellow
It means hot liquid or semifluid.
