Based on the weathering patterns you see,what rock type is most likely shown below?
Musya8 [376]

The correct answer is - limestone.

On the image, it seems that we have a representation of rock formations in a cave. They are evidently weathering. According to the manifestation of the weathering, the color of the rocks, and that it is most probably a cave, the chances are mostly likely that it is a limestone.

The weathering appears as a result of the water. The limestone is a sedimentary type of rock, thus it doesn't have strong structure. The water is able to gradually penetrate through it, making holes in it, and little by little weather it. In this way we have the formation of the water reservoirs, springs, cave systems.

Multiple sclerosis and atherosclerosis are similar in that they both refer to:
alukav5142 [94]

The conditions mentioned are both a type of sclerosis, which refers to the hardening of a certain anatomical feature.

In atherosclerosis, the affected <u>anatomical feature </u>is the artery. This is a condition that causes the <u>obstructions </u>of <u>blood flow </u>through the artery as a result of plaque buildup along the artery walls. Unlike with MS, atherosclerosis does not present symptoms until the obstructions are severe or the plaque loosens, which can lead to <em>heart attacks</em>, among other consequences.

In the case of Multiple Sclerosis, the affected anatomical structure is that of the nerve. This is a condition for unknown reasons, causes the <u>immune system </u>to attack the myelin covers of nerve cells which act to protect the cell. The absence of this cover causes the build-up of plaque along the nerve axon, <u>stiffening </u>and <u>disrupting </u>the communication of the nerves with the central nervous system.
