Explain the reason that many organisms found in the oceanic zone are unique and cannot be found anywhere else. Be sure to includ
Mice21 [21]

Answer:

Explanation:

There are four ocean zones named as the neritic zone, midnight zone, twilight zone and abyssal zone depending upon the depth of water and the availability of sunlight. Other factors like pressure, oxygen, salinity contributes to the diversity of organisms found and develop in these zones. These factors also makes the organism unique in forms due to living in the oceanic zone.  

The two adaptations are as follows:

1. Many organisms which live in the neritic zone are adapted to bouyancy. Some organisms float to conserve the energy for swimming, others float to fatch food near the surface of shallow waters.  

2. The animals in the twilight or disphotic zone are adapted to live life in darkness which is found in cold water and high pressure. They have adaptations such ability to see in dark waters and they produce  bioluminescence to catch food in darkness.

Speed and velocity are similar, but which thing makes them different?
Sedbober [7]

The velocity of the object is similar to speed but has one main difference: velocity takes into account the direction of an object. Since speed does not take direction into consideration, it is considered to be a scalar quantity. Thus, the speed of an object can never be negative.

Does mRNA model more closely resemble the DNA strand from which it was transcribed?
Bond [772]

Answer: No, mRNA ( messenger RNA) model does not closely resemble the DNA strand from which it is transcribed.

This is because mRNA strand is complementary to the strand of DNA template that is used in its synthesis during the process called transcription. The polarity of DNA template is 3' to 5' whereas that of mRNA transcribed is 5' to 3' that is both the strands have antiparallel polarity.

This is the reason template DNA is referred antisense. mRNA strand more closely resembles the sense strand ( which is complementary strand of DNA template in a double helix).
