Acell bearing cd8 on its surface would be most similar to or have the most in common with which of the following cells?
question 8 options:
follicular dendritic cells
nk cells
monocytes
macrophages
dendritic cells

Option). NK cells.

Explanation:

Cluster of differentiation 8 (CD8) can bed defined as a transmembrane glycoprotein that acts a co-receptor for the receptor present on T cells (TCR). The CD8 is marker for cells (cytotoxic T cells) as it is predominantly present on cell surface of these cells.

Along with cytotoxic cells, CD8 molecule is also expressed in surface of natural killer cells (NK cells), thymocytes, and myeloid dendritic cells.

Hence, a cell having CD8 on its surface (cytotoxic T cell) would be most similar to NK cells.

for  example, forests have higher evapotranspiration than other ecosystems,  such  as grasslands, because of their deeper roots and greater leaf area. thus forests have a net moistening effect on the atmosphere and become a moisture source for downwind ecosystems.

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.
