The components that make up the genetic code are common to all organisms. If a segment of a gene contains 27 nucleotides, none o
AVprozaik [17]

Answer:

9 amino acids

Explanation:

A segment of a gene that has 27 nucleotides will code for<u> 9 amino acids.</u>

<em>Each codon on the gene potentially represents an amino acid and a codon is made up of 3 nucleotides each. Hence, in order to find out the total number of amino acids that a gene segment with 27 nucleotides can code for, the number of nucleotides should be divided by 3.</em>

    number of amino acids = number of nucleotides/3

                     27/3 = 9 codons/amino acids

Larger the size of an organism bigger the size of its cells. Do you agree with this statement? Give scientific reasons.
vodomira [7]

Answer:

Disagree.

Explanation:

Though some cells are bigger than others, they do not scale with size. For example if you look at skin cells on a dog they would be similar in size to a skin cell from a human. When an animal or species is bigger it is usually just made from more cells.

omeli [17]

Answer:

<u>A. red blood cells containing malaria</u>

Explanation:

Malaria is a disease-causing pathogen in humans. It is caused by species of the parasite <em>Plasmodium sp.</em><em>,</em> which is transmitted as sporozoites by the Anopheles mosquito upon biting the host. These travel through the bloodstream to the liver where they mature into merozoites. These reenter the bloodstream and mature into trophozoites and schizonts that produce more merozoites.

When they multiply within the red blood cell, they <u>burst the red blood cell open</u>, and go on to infect other cells. This infection's symptoms are cyclic and include high fever, chills and other flu-like symptoms.

Malaria is a deadly illness, causing harm to its hosts, and in many cases death. <u>Thus, this cannot be defined as symbiosis, which is typically beneficial to both organisms.</u>
