which zone in the ocean is the most challenging to survive in?

Answers

Answer:

The Bathyal zone is the hardest to survive in.

Explanation:

Technically, the entire ocean is difficult to survive in. There's no oxygen and lots of scary ocean predators.

But the Bathyal zone, which is 1000 - 4000 meters below the surface of the ocean has no sunlight, making most of the sea creatures there have no eyes. Because this zone is so dark, with little food to survive in, fish don't hang out here.

Dear Mayor Thomson, As you know, our town just passed a new law. Kids can no longer ride skateboards on our towns streets and sidewalks. This is unfair. Our town does not have a skate park, and not everyone has a driveway. This means that some of us cant ride skateboards at all. 2You spoke about this new law last week at a town meeting. You said that riding skateboards on streets is dangerous. You are worried that kids will be hit by cars. However, we have many small side streets in our town. Cars rarely drive on these streets. It is safe to ride a skateboard on a side street in our town. 3You said that people walking on sidewalks are afraid of skateboarders. They think that skateboarders might crash into them. This is not true. My friends and I have never crashed into someone walking on a sidewalk. We slow down when we see people. We smile and say hello. 4You also said that kids riding skateboards make too much noise. You believe that the people of our town want peace and quiet and do not want to hear us clang our skateboards on curbs. But children are rarely ever quiet when they play. Kids playing in yards make noise. People driving cars honk their horns. Skateboarders are not the only people who make noise. 5You also said that riding a skateboard is dangerous and kids could fall and be seriously hurt. I wear a helmet in case I bump my head. I also wear knee and elbow pads. My friends do this, too. This will keep us from being seriously hurt if we fall. 6Please change this law, Mayor Thomson. It is unfair to the children in our town. Many of us ride skateboards to get from place to place. We also ride them for fun. We are not hurting anyone and we are careful. Sincerely, Reginald CarterIn which argument is the slippery slope fallacy used to oppose the argument in this text? Use the table shown. A) The kids want the right to skate on any private or public property they choose. B) Reginald Carter is just a kid, he does not really understand what a mayor does. C) The mayor knows what is right for the kids, Reginald is too young to realize that. D) If we let kids start doing whatever they want, they will all just drop out of school.
