Answer:
In the DNA structure all the genetic information of a living being is stored and through the replication of the DNA this information is transferred from one generation to another, which allows the reproductive inheritance.
Explanation:
DNA is a molecule composed of two thin strands of filiform polymers that intertwine with each other and form a regular double helix structure. Each chain is a poly-nucleotide (polymeric grouping of nucleotides), which are made up of: a pentose-type sugar called deoxyribose; a nitrogen base and a phosphoric acid group. This nucleic acid contains the information of the inherited characteristics of each living being and the sequences for the creation of amino acids that will generate the vital proteins for the functioning of organisms.
The nitrogen bases of DNA can be of four types: adenine (A), cytosine (C), thymine (T) or guanine (G), together with a phosphate group. In the sequence of this compound, all the genetic information of a living being is stored, essential for protein synthesis and for reproductive inheritance, that is, without DNA there would be no transmission of genetic characters.
DNA replication occurs before the cell divides and consists of obtaining identical copies of the fundamental cellular information for transfer from one generation to another, thus constituting the basis of genetic inheritance.
Choice A. Fish can accumulate various heavy metals in them through a process known as bioaccumulation. This applies mostly to large predatory fish like tuna, because they eat large quantities of other fish.
Answer:
It can negatively or positively influence organisms living nearby.
Explanation: Say humans were logging a forest...that would have a negative impact on the surrounding organisms. Birds could lose nests, lower plants could lose shade, burrows could be uprooted. On the other hand, say a wildlife bridge was developed over a highway. This could provide more room for organisms to make home, and create a safe way for them to cross the road.
Overall, I'd say there are more negative impacts than there are positive as we much more frequently ar clearing entire environments to make more room for people to live. This, in turn, lowers the carrying capacity of the affected environments.
