Al of these will be the consequences except C, increase in polar ice. The rise in temperature is already causing the polar ice to melt down. The further increase in temperature will make the situation of the polar ice worse. the rise in vegetation in Tundra and Tyga regions could be seen because they are very cold areas and temperature increase may help vegetations to survive.
The cardiovascular system
The cardiovascular system is an
organ system which allows blood to circulate and transports nutrients, gases, hormones,
and blood cells within the cells of the body for proper functioning of human
cells and organs. The cardiovascular system is made up of the heart and the
circulatory system. A group of arteries, arterioles, and capillaries help to carry
blood from the heart to other parts of the body.
