Some of the world would be dark and some would be light so it would get confusing
Originally it was made from cardboard and wood but now its stone and brick
The main difference in the process of waste removal between unicellular and multicellular organisms is the fact that unicellular organisms rely on only their membrane and organelles, the whole process is in inside the cytoplasm of the cell and once waste is formed, it is "packed" in special sacs called vacuoles and then, through the process of exocytosis they are being left out of the cell. On the other hand, multicellular organisms most often have specific organs that are in charge of the process of digestion, absorption and excretion or removal of waste.
Igneous rocks -
1. texture, can be smooth, fine-grained, coarse-grained, glassy, or porphyritic.
2. origin, geologists use this to study to know where it was found, like it could be formed by hardened magma under the earth's surface.
3. mineral composition, some of these rocks had other minerals that help us find all the exact minerals. (like a tree diagram)
Sedimentary Rocks-
1. the only rocks with fossils, trace fossils, or sedimentary features.
2. composed of strata (layer) or laminations (bed)
3. sedimentary rocks have grains instead of crystals.
4. Metamorphism destroys fossil evidence and lava destroys its organic material before the fossilation can take place.
Metamorphic Rocks-
1. rarely have fossils & they are classified by these textures and compositions
2. they can react with acid. may or may not have a curved or bent foliation
3. can be formed w/ only one mineral & they rarely have pores or openings.
