he answer is because <span>samples of air taken over erupting volcanoes shows that volcanoes
contribute a small amount of chlorine in the stratosphere compared to CFCs. Volcanic
eruptions account for a large instability of chlorine from land to the
atmosphere on a yearly basis. This is in addition to chlorine that enters the
atmosphere from sea spray, industrial processes and biological gases which are
from CFCs. All of these inputs happen near or at the base of the atmosphere. Very
little of the material emitted from volcanoes makes it up into the upper
reaches of our atmosphere which is the stratosphere where it could touch the
ozone layer. However, most of it is believed to be deposited lower down which
is in the troposphere, where it then rained out back to the surface of the
earth.</span>
Answer:
The exchange of chromosome segment between non-homologous chromosomes is called translocation.
It is of two types:
There is an exchange of chromosome segments between two non- homologous chromosomes in reciprocal translocation.
- Non- reciprocal translocation
A part of chromosome is translocated from one non-homologous chromosomes to other so that one chromosome becomes deficient and another non-homologous chromosome gains the piece of chromosome and becomes long.

Good luck on your assignment..
Answer:
The acidic environment in the stomach stops the action of the amylase enzyme.
The stomach will secrete digestive juice that contain hydrochloric acid and digestive enzyme such as pepsin to digest protein.
The HCL create an acidic environment that will deform the ionic and hydrogen bond of the amylase which cause the enzyme to be denatured.
The formula for the volume of a cone is V=(1/3)πr^2h, where V is volume, r is radius, and h is height. Plug in and solve:
V=(1/3)π7^2(27)
V=49(9)π
V=441π
V=1385.4412cm^3
