Answer:
False, since it takes more than one million years
Explanation:
Speeds can be faster for small-scale convection occurring in low-viscosity regions beneath the lithosphere, and slower in the lowermost mantle where viscosities are larger. A single shallow convection cycle takes on the order of 50 million years, though deeper convection can be closer to 200 million years.
Answer:
A.) Aa
Explanation:
A heterozygous gene is known as having two different alleles of a particular gene or genes. The correct answer is option A because both letters are different, versus the other two options where both are capital or lowercase.

because there is no friction or wind resistance, the speed of the satellite remains the same
Answer:
<em>This is an example of natural selection (adaptation).</em>
Explanation:
Natural selection tends to favor those organisms which are better adapted to live in an environment.
As tortoises having flat shell and long neck were better adapted to live in barren area, hence through natural selection those organisms were favored in such an ecosystem.
As tortoises that lived on the vegetative lands were more adapted to live in such an ecosystem, hence through natural ecosystem these organisms were favored and increased in numbers.
