Hello. You forgot to place the diagram. The diagram is added just below.

B. cell structures.

Explanation:

Cells are their functional and structural units. Basically the cells are formed by a cell membrane (delimiting the cell and providing protection), a cytoplasm (where the organelles are) and a nucleus (responsible for reproduction). However, some characteristics allow the cells to be classified into two prokaryotic and eukaryotic groups. Although similar, these cells have different structures that help to differentiate them quickly. Among eukaryotic cells there are animal and plant cells, which also have different structures that help to differentiate them, as you can see in the diagram.

answer: grassland biomes are closer to the equator and receive more rain.

grasslands are biomes that are dominated by grasses rather shrubs and trees. savanna are biomes that exhibit grasses, shrubs and small tree as vegetation. grasslands are located near the equator of the earth. these are found in north america. savanna biomes are found in africa, south america, australia and india. grassland exhibit moderate climatic conditions, it receives   amount of rainfall higher than savanna.   therefore, savanna exhibit dry and hot climatic conditions.
