Orogenic activity for the duration of the Cenozoic was
concentrated in the Alpine-Himalayan orogenic belt and the Circum-Pacific
orogenic belt. The Cenozoic Era is the current era animal history, which spans the
time period from 66 million years ago to the present day.
Answer:
D. A positive charge, because of a covalent bond with oxygen
Explanation:
A water molecule contain both hydrogen and oxygen atom. Water is a polar molecule because it has positive electric charge in one of it's poles and negative charge on the other. The hydrogen is positively charged and the oxygen is negatively charged which are bonded by covalent bond. Hydrogen is positively charged because it cannot attract electrons strongly like oxygen which is positively charged. There is unequal sharing of electrons in water molecules and this is why oxygen is slightly negative and hydrogen is slightly positive.
Our actions is affected by physical environment.
I think it would be c. 1.5 because it is half the size. Also good luck for your quiz
Answer:
The correct answer is d. suggests that the time since divergence may not be sufficient for complete reproductive isolation to have occurred.
Explanation:
Polar bears are evolved from brown bear and grizzly bears are subspecies of brown bear so polar bears and brown bears are different species. These two species habitat is different so they are geographically isolated but due to the melting of ice by global warming, their niche started overlapping.
Commonly they do no reproduce with each other because of the reproductive isolation but they can produce viable hybrids called growlers and pizzlies if interspecies reproduction takes place which shows that the time interval since divergence is not enough that can make these two species completely reproductive isolated. So the right answer is d.
