Earth's service would be bare. There would no longer be life and all water ways would become dried up due to the intense ultra-violent rays of the sun.
The statement that best compares gymnosperms and angiosperms is : A. Both reproduce sexually, but gymnosperms contain only xylem and angiosperms contain xylem and phloem.
Gymnosperms produce exposed seeds, not enclosed in fruit whilst Angiosperms have Fruits, flowers, and endosperms as defining characteristics.
During respiration, members of the animal kingdom use oxygen and then release carbon dioxide as a waste gas.
Members of the animal kingdom have a respiratory system that is composed of muscles, and airways that functions together to transport air into lungs, and the oxygen is used by cells. Carbon dioxide is also transported away from the cells as a waste gas. Respiration relies on other systems, such as the circulatory system, to transport oxygen and carbon dioxide to and from cells.
Adenosine Triphosphate is a compound used by the cell to store energy. Together with NADP, ATP is responsible for carbon dioxide reduction. Carbon dioxide is said to be reduced when it loses oxygen, reacts with hydrogen or gains electrons. Carbon dioxide becomes part of Glycerate 3-phosphate.
