1. True. Establishing more sites for the protection of biodiversity across the world can go a long way and would have a chain reaction in the ecosystem. Thus, it will save a lot of our planet's biodiversity. 2. a. -Philiab. -trophicc. eco-d. eu-3. A habitat is where certain species, animals, or organisms naturally live, feed, reproduce, etc. Examples: ocean, rainforest, deserts. An ecosystem has two components: living and non-living organisms which interact with each other to maintain homeostasis. The primary difference between the two is the presence of interaction between the things in the environment.4. Energy5. Producers6. Sun7. (No choices provided) One of the top factors that threaten the survival of species is caused by humans, man-made phenomena. 8. Answer: Polar bears.

It really doesn't effect the earth. Most of this is all made up. They say this so you could go away from the truth
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.
