Question: Which of the following are appropriate units for power?
A) newton·meter
B) watt
C) H.P./sec
D) joule/sec
Answer:
Watt and Joule/sec are the appropriate units for power.
Explanation:
As per the question, the physical quantity given is power.
The power is defined as the rate of consumption of energy or the rate of doing work.
Let us consider W is the amount of work done by a body in time t .
Mathematically the power of that body is written as -
power 
The unit of work is joule and the unit of time is second.
Hence, the unit of power is joule/sec.
we know that one joule/sec. = one watt.
Hence, watt is also another unit of power. Newton-metre can not be a unit of power . It may be considered as a unit of work.
Similarly H.P/sec is also not a unit of power. Here H.P stands for horse power which is another unit of power . Hence, joule/sec. and watt are the appropriate units of power.
Answer:
D
Explanation:
Prokaryotic cells have no nucleus, eukaryotic cells do. A squirrel is eukaryotic, therefore it’s genetic material will be stored in the nucleus.
Answer:
Glycolysis
Explanation:
Glycolysis. Six-carbon glucose is converted into two pyruvates (three carbons each). ATP and NADH are made. These reactions take place in the cytosol.
Answer: The appropriate information that will be used to fill the blanks includes the following respectively:
-1.7
- increased
-70%
- 0.5
- decreased
- 50%
Explanation:
The green (topmost) data point at June 2011 shows a proportional change of about 1.7, which means that the native fish population INCREASED by about 70 percent when 95 percent of the lionfish were removed. In contrast, the orange data point at June 2011 shows a proportional change of about 0.5, which means that the native fish population DECREASED by about 50 percent when only a quarter of the lionfish were removed (a result that was almost the same as when none of the lionfish were removed).
The native fishes are being haunted by the lion fish, from the results, removing just few of the invasive lion fish will not make a difference. In other to help the native fish survive, many of the lion fish has to be removed.
