Question:

What is one effect that global warming has on the coral reefs?

Answer:

Global Warming can lead to Coral Bleaching. Coral are made of tiny animals called polyps that excrete calcium carbonate to form the coral reef itself. These polyps have a symbiotic relationship with an algae called zooxanthallae. The zooxanthallae is what gives the corals their bright colors. Corals prefer temperatures between 20 and 36 degrees celsius. As the earth gets hotter than 36 degrees celsius, corals can become stressed. This stress will cause them to expel the zooxanthallae. Once the zooxanthallae has been expelled, the corals begin to lose their color. This is known as coral bleaching. Once the corals are bleached, they are still alive, but they are weakened and more susceptible to coral diseases.

Question:

What is the difference between anxiety and fear?

Answer:

Anxiety is caused by the brain imagining possible danger. Whereas, fear is caused by the brain's reaction to an actual danger. For example: If Jerry is watching a video of someone that fell off of a boat, this may cause his brain to imagine the possibility of him falling off of the boar; this would be anxiety. Whereas, if Jerry fell off of a boat and did not know how to swim, he will feel fear. The difference here is, initially Jerry was just thinking about what *could* happen if he fell of of the boat; Anxiety. When Jerry actually falls off of the boat, there is an *actual danger* in place because he can not swim; This would cause fear.

Answer:

Mangroves are the only group of trees that can grow and thrive in salt/saline water. Similar to other trees, mangroves require freshwater to survive. To acquire this freshwater, these trees can either expel or reject salt in the water that they absorb. There are 4 different types of mangroves: - The Red Mangrove - The Black Mangrove - The White Mangrove - The Buttonwood Mangrove. Each type of mangrove has specific traits that help them fill their niche.
