Due in 2 hours , best answer gets ! you have to be able to suggest the job of an unknown cell based on it's structure. in order to facilitate this you need to revise ks3 learning on cell structure. find an electron-micrograph of the following cells. explain how their structure their function: red blood cell; muscle cell; neurone; palisade cell; root hair cell.

Its biconcave shape maximizes the surface to increase the efficiency of oxygen absorption. Its shape also allows it to "pinch" through the capillaries around the body. Red blood cells do not have a nucleus, which increases the oxygen capacity. sorry it took so long for an answer hope you get a good grade!

metamorphism is the change of minerals or geologic texture (distinct arrangement of minerals) in pre-existing rocks (protoliths), without the protolith melting into liquid magma (a solid-state change). the change occurs primarily due to heat, pressure, and the introduction of chemically active fluids. i hoped i !

try using substitution:

x + y - 6 = x - y. (i'm not giving you the exact answer). since 0 = x - y, then sub 0 in the equation with x - y. combine your like terms, and then use inverse operations, and you'll have your answer.
