Answer:
b) plasmid
Explanation:
A plasmid is an extrachromosomal DNA molecule that found in a cell that replicates independently without the need for chromosomes. A plasmid is small and is also not attached to the chromosomal DNA. Generally, plasmids are a circular piece of double stranded DNA materials that are present in bacteria.
Plasmids are used in a molecular biology laboratory for gene manipulation. they are able to transfer genes to a DNA through DNA recombinant technology and also aid DNA replication in bacteria. Plasmids are also used to study antibiotic resistance.
Vertebrates or invertebrates reason being that invertebrates such as an arthropod, mollusk, annelid, coelenterate, etc. <span>comprising 95 percent of animal species and about 30 different phyla Crazy right? Vertebrates like us and other creatures make up the rest which have a backbone unlike invertebrates..</span><span />
Answer:
<em>No, these exceptions do not discredit natural selection.</em>
Explanation:
Natural selection tends to favour those organisms which are better adapted to live in an environment. But it does not completely remove the other organisms from the world that are less adapted to live in an environment. Usually, the number of these organisms that are not favoured by natural selection is very less as compared to the number of organisms which are favoured by natural selection. As we see, the number of albino animals is far lesser as compared to their wild-type animals.
