Since the earth is rotating while this is happening, two tides occur<span> each day.

Answer:
Option B, in the middle of the current gyres
Explanation:
The zones of upwelling have high productivity as they have adequate climate and weather condition along with availability of nutrients. The same is applicable for Equator and coastal regions. The productivity of Antarctica is low but not less than that of current gyres as in the middle of the current gyres there are high current streams that reduces the biological productivity.
Hence, option B is correct
Answer:
The correct answer will be- genes can be transferred among species
Explanation:
Green fluorescent protein or GFP is a protein which is naturally expressed in a jellyfish called <em>Aequorea victoria</em>. The protein absorbs the light and emits it in green color.
Scientist isolated the gene of the protein from the jellyfish in the 1960s and transferred it to the genes of the other species like bacteria or mice.
This shows that although the species can be isolated from the reproduction by reproductive barriers but the molecule containing code of life can be transferred easily without any barrier.
Thus, genes can be transferred among species is the correct answer.

Answer: <u><em> a) Friction</em></u>
Explanation: <em>Friction is a force that opposes motion. When two objects are in contact, friction is acts in a direction opposite to the motion of the object.</em>
