Astudent uses a microscope to look at cells from a tree leaf and a fingernail. which structure will the student see in the tree leaf cell that is not in the fingernail cell? a. mitochondria b. cilia c. cell wall d. ribosomes

Option C cell wall

Explanation:

Cell wall is only found in plant cell. A cell wall is to provide structural support, filtering and also protection to plant cell. Since the cell from fingernail is not a plant cell and therefore the cell wall is not available. The rest of the organelles in the options such as mitochondria, cilia, ribosomes can be found in the cells from a tree leaft and a fingernail.  

humans can cause extinction of a species through overharvesting, pollution, habitat destruction, introduction of invasive species (such as new predators and food competitors), overhunting, and other influences. explosive, unsustainable human population growth is an essential cause of the extinction crisis.
