Explanation:

This is because humans have 46 chromosomes, however this is comprised of the 23 chromosomes in each sperm and egg cells. This shows that genes are not transferred through the blood but by sperm and egg cells. Also genes and chromosomes are stored in the nucleus of cells, however red blood cells do not have a nucleus further showing that this is false.

Readme [11.4K]
This condition is known as lymphadema. After surgical removal of chain lymph nodes has occurred, the excess of lymph fluids in the lymph vessels might not find its way to the bloodstream as a result of being blocked or other reasons, and hence localized swelling in that area occurs as a result of addition of the fluids. In most cases, lymphadema affects only a single arm or leg, and is commonly brought on by cancer treatment that involves damging or removing lymph nodes.

soldier1979 [14.2K]

Answer:

Increase occur in skin diseases and decrease occurs in the Earth's average temperature.

Explanation:

If both Carbon Dioxide and Ozone levels began to decrease, increase occur in skin diseases and decrease occurs in the Earth's average temperature. The decrease in ozone levels allows more UV radiation to reach the Earth's surface which lead to various diseases such as skin cancer, cataracts, and weakened immune systems. The atmospheric carbondioxide gas is responsible for the increase of surface temperature by trapping reflected solar radiations so decrease in carbondioxide concentration will leads to lower surface temperature.
