Freshwater means low salt content. The zones namely Standing which is compose of ponds and lakes and has littoral zone which algae,floating aquatic plants and clams can be found. Next is limnetic zone and has plankton. Next is Flowing includes streams and rivers and in there resides catfish and carp. For sea water it has Marine which has aphotic zone where anemones,arrow worm and angler fish resides.Another, coastal zone compose of coral reefs and mangrove and lastly the intertidal zone with small critters.
Answer 1) : Change in direction.
Explanation : When an airplane starts to turn from south to west at constant speed gets accelerated due to change in direction. The change in direction of the airplane causes the airplane to accelerate in the direction of west while it was moving in south. Here the acceleration is being affected because of the change in direction of the object moving with a constant speed.
Answer 2) Change in direction and increasing speed.
Explanation : When a biker was riding at the speed of 5 m/s north and then changed the direction to west at an increased speed of 7 m/s this was due to increased speed and change in the direction of the bike.
There was two factors which contributed to change the acceleration in this case. It was because of change in speed of the bike and also because of change in direction. This kept the bike in acceleration by increasing the speed while changing the direction.
Answer 3) Increasing speed.
Explanation : While the shopping cart was observed to speed up on the runaway while it goes down a hill gets accelerated due to change in its speed.
In this case, when the shopping cart is been released from the upside runaway; as it goes down it gains more speed due to the slope of the runaway. This is because the acceleration is increasing because there is increase in the speed of the shopping cart.
Answer:
d. Researchers said the flu shot reduced the risk of developing the flu when it actually didn't.
Explanation:
A Type I Error can be defined as the error that occurs in hypothesis when a researcher rejects the opposite of his hypothesis even though the opposite of his hypothesis is correct or true. Type I Error can also be called a False positive.
In the question above an hypothesis was carried out by researchers to determine if getting a flu shot would reduce the risk of developing a flu.
The truth is " Getting a flu shot actually reduces the risk of developing a flu"
But the researcher hypothesis test result that would result in a Type I error says "Researchers said the flu shot reduced the risk of developing the flu when it actually didn't".
This result of hypothesis test of the researchers above is a rejection of truth (the truth is an opposite of the researchers hypothesis test) and it would result in a Type I Error.
