Answer:
When plants are growing, photosynthesis outweighs respiration. As a result, plants take more CO2 out of the atmosphere during the warm months when they are growing the most. Levels of carbon dioxide in the atmosphere rise and fall each year as plants, through photosynthesis and respiration, take up the gas in spring and summer, and release it in fall and winter. Now the range of that cycle is expanding as more carbon dioxide is emitted from burning fossil fuels and other human activities.

A test to see whether the embryo exhibits spiral cleavage or radial cleavage.
Eight-cell stage in the development of animals differ between protostomes and deuterostomes. Cleavage of Protostomes is spiral and determinate, while in Deuterostomes is radial and indeterminate.
The stage of coelom formation also differs: in Protostomes it is schizocoelous-mesoderm forms coelom; in Deuterostomes it is enterocoelous-archenteron form coelom.
Final and main dfference:
• Protostomes-mouth develops from the blastopore
• Deuterostomes-anus end develops from blastopore.
The three tenets to the cell theory are as described below: All living organisms are composed of one or more cells. The cell is the basic unit of structure and organization in organisms. Cells arise from pre-existing cells.
