Answer:
Option A, Upper areas are cooler than others
Explanation:
The relation between the latitude and climate i.e temperature is inversely proportional.
Regions located at lower latitude are actually located at a distance far away from the equator. An equator receives the highest sunlight thus a region located at a distance far away from the equator receives lower amount of sunlight due to which its temperature is a bit colder as compared to regions lying close to the equator.
Hence, option A is correct
The waxy coating is a lipid that can help prevent excess water loss in dry environments.
Answer:
C. I and III
Explanation:
A mutation needs to occur in a gamete cell in order to be passed down to the next generation.
If it occurs in a somatic (body) cell, the mutation will only be present in that organism.
On the other hand, in a gamete cell, the mutation will pass down because gamete cells are directly involved in the genetic makeup of the offspring.
So, since sperm and egg cells are gametes, mutations in those cells would get passed on.
The correct answer is C. I and III
