How can fish farms reduce over fishing?
Answer:
FARM FISHING: THE SOLUTION TO OVERFISHING?
03/02/2017 MARC ARENAS CAMPS 9 COMENTARIS
We have heard many times that fishing grounds are being depleted due to the overexploitation of species. It is also widely said that farm fishing could solve this problem. But, are farms the solution to overfishing?
FARM FISHING: THE SOLUTION TO OVERFISHING?
In general terms, the status of wild fish stocks has not improved. By 2013, 58.1% of fish stocks were fully exploited, 10.5% were under-exploited and 31.4% were overexploited (FAO, 2016). Thus, 30% of the populations suffered from overfishing.
This is due to the increasing consumption of fish. According to a report published by FAO, in 2014 each person ate on average about 20 kg of fish, twice as much as in 1960.
On the other hand, since the 1980s, wild catches have remained stable. However, the supply of fish for human consumption has increased considerably. So, if consumption has increased and fishing has remained stable, where does the rest of the fish come from?
The explanation for this fact is in aquaculture: in 2014, catch production was 93.4 million tonnes, while aquaculture production amounted to 73.8 million tonnes. In other words, 44% of the fish came from aquaculture.

What are time zones?
Why different places have different time zones?
What's the time in your country right now?
time zones are just what they sound like, in certain areas, in one spot it might be 12:00am in the next time zone, it would be 1:00am
the reason there different time zones is because on one side of the world it's day, on the other side, it's night.
for example in Pacific time zone compared to the China standard time, china standard time is +13 hours ahead of a place like California, if that makes sense.
where I'm at it is 1:30am

Look at the locations of the warm and cold fronts you drew in part D. In the answer space, describe the cloud cover, wind speed, and wind direction expected at these locations. Which US states will be affected?
A warm front would represent the boundary that is between two cold and warm masses of air and they are less dense than cold air when placed at constant atmospheric pressure.
What is a Cold Front?This refers to the region in the atmosphere where a cold air mass takes over from warmer air.
This cold weather front is usually found in the NorthWestern areas to the SouthEastern areas so, if you look at your school textbook, you should be able to get the states that would be affected.
Please note that your question is incomplete so I gave you a general overview to help you get a better understanding of the concept.

Use the properties of seawater to describe the characteristics of mixtures.
Seawater is a heterogeneous mixture with dirt and mud particles. It is a homogeneous mixture with dissolved substances.
What are mixture?A mixture is made up of two or more substances that are not chemical combined together. This is because there is not bond formation between the substances.
A mixture can either be heterogeneous or homogeneous mixture.
A heterogeneous mixture is made up of different compositions which are visible to the eye when seen. Example is mixture of dirt and mud.
A homogeneous mixture is of uniform composition. Example is the mixture of salt and water.
Therefore seawater can be used to describe the characteristics of mixtures because it contains both homogeneous and heterogeneous mixtures.

Suppose a bicycle was coasting on a level surface, and there was no friction. What would happen to the bicycle?
As there is no friction on the bicycle, there would be no force given by the surface to resist the motion of the cycle. So, it would continue going at a constant speed.
Answer:
It would keep going at Constant Speed
Explanation:
The bicycle would keep going at constant speed because of inertia. Objects in motion stay in motion unless they are disturbed by an external force
