<h2><u>Answer:</u></h2>
Fossil: is preserved pre historic life form present under ground at high pressure for a long time.Animal die and burried under layers of sediments.
It provides evidence about the history of life on earth. It also shows different groups of organisms, including species,that have changed over time. Because the formation of any fossil depends upon the precise combination of conditions.
As the world changes, plants and animals change with time . From fossils we compare organisms of modern time with ancient , the species we see today are very different from species that lived in the past. Thus, the fossil record can be used to show that organisms changed to meet new condition.
Answer:
Mutation is a alteration in the DNA sequence in a gene during cell divison iwhere gene is coded mitakeny or due to the error. Mutatio is a random process as it can not be determind or known befor bthechange in sequence what gene or DNA would be effected by it or what genes would be transfer from the parents.
Natural selection is a process where some of the traits that are helpful in the surviving and increasing the number of individuals in a population and transfer from one generation to other according the adaption and change over the long timeline. Thus, it is not random and based on the traits that are helpful in a environment or for the survival of
Without knowing your previous answer I would say C
because normal cola is a denser fluid than diet.
Answer:
The correct answer is option E) "The presence of one or more introns".
Explanation:
Introns are non coding sequences located within genetic sequences that are removed during RNA maturation by a process known as RNA splicing. A gene that has 2000 nucleotide pairs but is translated into a mRNA molecule with 1200 nucleotides most likely have one or more introns that in conjunction are of 800 nucleotides in size. Once the intros are removed from the mRNA molecule the coding sequence is ready to be translated into a protein.
