These should be 5 science dont answer if you dont know these 5 questions ok but if you know at least 4 pls and if you cant answer them cause if 2 people already did pls just comment your answer so i dont go with a wrong answer tysm. question 1 #image is for this problem using the data in the table above, which best explains how muscle cells and skin cells are adapted for our environment? muscle cells have more mitochondria than skin cells because the human body is made up of more muscle than skin. skin cells need more energy, so they have less mitochondria than muscle cells. muscle cells need more energy, so they have more mitochondria than skin cells. muscle cells need more mitochondria than skin cells because skin cells require a cell wall. question 2 inside the nucleus are chromosomes carrying your dna. this has the genetic information for everything in your body. what part of a mall is like the dna in your nucleus? mall directory largest department store (i.e. macy's) food court entrance to the mall question 3 choose the best term to complete the analogy: wrecking crew: old building : : : damaged organelle cell membrane lysosome mitochondria cell wall question 4 you are looking at a slide using your microscope and see many things moving about. you notice a very rigid structure outlining the cell. you like to have as many facts as possible to back up any claims you make, specially in science. what else would you to be sure what type of cell you are seeing? mitochondria chloroplasts lysosomes cell membrane question 5 you are in a boat out on the lake. each part of the lake represents parts of the cell. the embankments represent the cell membrane, the boat is the nucleus, and the water would be the cytoplasm, what would the fish represent? cell wall dna organelles none of the above
