Answer:
The correct answer is option C) "Remora fish stick to large sharks, receiving a free ride and scraps of food the shark does not eat. The shark is neither helped nor harmed".

Commensalism is defined as a type of interspecies relationship at which one individual gets benefited and the other is neither benefited or harmed.

They have the least energy and longest wavelengths
Radio waves have the longest wavelengths and the least energy.
The correct answer is A
The scientist can determine that this nucleic acid is a DNA molecule, because it contains Thymine, which does not occure in the RNA molecule. The RNA molecule contains Adenine, Guanine and Cytosine just like the DNA, but unlike the DNA it contains Uracil, not Thymine.
Secondly, the scientist can say with certainty that this DNA molecule is surrounded by a nucleus based on the structure of the nucleic acid described. Only eukaryotic cells have ladder structure. The prokaryotic cells have circular DNA and do not have any organelles, like the nucleus. Therefore, from the ladder structure of the DNA the scientist can see that the cell has a nucleus.
Topography is occupied with how individuals and societies identify with the physical environment. The biggest environment of which we are part is the biosphere. The biosphere is the part of the world's surface and its environment where living beings exist. It has additionally been portrayed as the life-supporting layer that encompasses the Earth.
The biosphere we live in is comprised of biomes. A biome is a vast topographical district where certain sorts of plants and creatures flourish.
