What is the affect of increasing the temperature of the water?
What happens when you add pollution to the water?
Can coral survive bleaching?
What is coral?
Answer:
Explanation:
Increasing temp in water makes it start to boil and evaporate into the atmosphere, in terms of climate change it makes it hard for many organisms to survive because they have to adapt quickly to the waters rapidly rising temperature. When you add pollution to water the water would become contaminated and not be able to support life or be fit for human consumption.
Coral cannot survive bleaching because it harms the coral to the point of its destruction.
Coral is an animal that can grow into big reefs that create large ecosystems for many organisms. They are in the ocean. The biggest coral reef is the great barrier reef in Australia.
Imagine that you and your friend are at the beach. You have your chairs and umbrella set up in the perfect spot near the water so you can jump in to cool off with ease. A few hours into your stay, the water line has managed to creep up closer and closer to your chairs and your things start to get wet! Your friend points up at the Moon and says it is to blame. What does this mean? Write a response in complete sentences. plz someone help!!!!!!!
Answer: High tides and low tides are caused by the moon. The moon's gravitational pull generates something called the tidal force. The tidal force causes Earth—and its water—to bulge out on the side closest to the moon and the side farthest from the moon. ... When you're not in one of the bulges, you experience a low tide.

List the characteristics of life that plants and animals in a food web share
Answer:They are movement, nutrition, respiration, sensitivity, reproduction, excretion,and growth.
Explanation:
Matter are anything that is made up of atoms. The quantity of matter can be observed only on the basis of mass and volume calculation. Thus, movement, nutrition, respiration, sensitivity, reproduction, excretion and growth are the characteristics of life that plants and animals in a food web share.
What is matter?Matter is a substance that has some mass and can occupy some volume. The matter is mainly used in science. Matter can be solid, liquid or gas.
So as we saw that matter has some mass so mass can be measured in gram only. Mass can also be represented as number of molecules. We also saw that matter occupy some volume and that volume is measured only in liter. Movement, nutrition, respiration, sensitivity, reproduction, excretion and growth are the characteristics of life that plants and animals in a food web share.
Thus, movement, nutrition, respiration, sensitivity, reproduction, excretion and growth are the characteristics of life that plants and animals in a food web share.
