What did you learn about the channel on Mars from the new NASA data? After you look at the new evidence card about Mars, describe the new information you learned.

The rocks looked familiar to the rocks found on Earth in these water channels. Moreover,  conglomerate rock was found near the base of the channel on Mars.

b.have there own function.

the "power" of a lens is its resolution power, or its ability to distinguish between to closely located points. with the low power lens, it is likely you will see the rough form of the hay and maybe some movement of dots around the hay. however, when observed with the high power lens, the detailed features of the hay become visible and the microbes being grown are more clearly visible.

i hope this you
