Answer:
Climate change lead to the destruction of corals due a warming of the oceans, increase in ocean acidity as gases such as carbon dioxide are absorbed into the oceans, rise in sea level due to melting glaciers and increase in precipitation, changes in storm patterns, etc.
Symbiosis is a close relationship between two dissimilar organisms which usually results in benefits to one or both organisms.

Explanation:
Greenhouse gas emissions from human activities have led to an increase in global surface temperature. This has resulted in a warming of the oceans, increase in ocean acidity as gases such as carbon dioxide are absorbed into the oceans, rise in sea level due to melting glaciers and increase in precipitation, changes in storm patterns, etc.
The warming of the oceans poses a great threat to life and activities in the ocean. Coral reefs especially are affected by a warming of the ocean in the following ways:
- mass coral bleaching- with increase in ocean temperature, corals remove the algae living in association with them that are responsible for their colour, thereby turning corals white. With prolonged bleaching periods, the corals eventually eventually die
.
- Sea level rise: with rise in sea level comes a likelihood of increase in flow of sediments into the sea. This sediments when deposited on corals found near land suffocates and kill the corals.
- Changes in storm patterns: stronger and more frequent storms can lead to a destruction of coral reefs.
- Increase in the acidity of oceans results in death of corals.
Corals and algae exist in a symbiotic (mutualistic) relationship in coral reefs. The coral provides the algae with a protected environment and compounds they need for photosynthesis. In return, the algae produce oxygen and help the coral to remove wastes.
Therefore, symbiosis is a close relationship between two dissimilar organisms which usually results in benefits to one or both organisms.
<span>The purpose is to prevent going into the negative zone. When you start paying with checks and you don't have money on your account that's the same as stealing things which means that you can get arrested for paying with checks while not having money. It's like fraud. Also, in case you're late with payments, you can get interest rates that don't suit you.</span>
Answer: F = M A. Centripetal acceleration = V-squared / R. So F=M V-squared/R. =. 85 x 225 / 20. = <u>956.25 Newton's</u> (about 215 pounds). That's the force required to keep that mass moving at that speed around that circle. If the force is less, or not there, then the 85 kg moves slower, or leaves that path.
Answer: competition
Explanation:
Competition is an ecological interaction in which two organisms interact with each other in order to obtain the same resource. The resource can be food, shelter, mate or other. The competition can be intraspecies which means the members of the same species compete for the resources. The competition can be interspecies which means members of the two distinct species compete for the same resource. Generally the competition leads to the decrease in growth, abundance and distribution of members of the inferior species and the members of the superior species derives the resources.
