Given what we know, we can confirm that the statement in the question is in fact true, by the end of the eighth week, the embryo is only 1 inch long and weighs just 1 gram.
<h3>What else do we know about the
embryo in this time frame?</h3>
During the first eight weeks, the embryo undergoes many changes. At this time:
- The legs and arms have formed.
- The fingers and toes are beginning to develop.
- It begins to be called a fetus.
- It is developing the lungs and lymphatic system.
- and much more.
Therefore, we can confirm that the statement that by the end of the eighth week, the embryo is only 1 inch long and weighs just 1 gram, is in fact true.

Explanation:
Mutations introduce novel variety in a population.
During the process of cell division, spontaneous changes within the genome can arise. These mutations are errors occur when copies of the DNA within the cell are made; mutations may range from small changes called single nucleotide polymorphisms, to large scale deletions, and additions which span multiple genes. There are two types:
- somatic: these only occur within certain cells, and arise from environmental factors such as UV light
- hereditary: occur within germ cells of the parent and later the fertilized egg which forms a zygote; these are present within all cells of the new organism.
Further Explanation:
During reproduction other events, such as crossing over during meiosis, mutations lead to increases in genetic variation. This variation refers to the genetic characteristics present within a species. Mutations may be either beneficial or deleterious; they are maintained within cells, as they form new traits called alleles. Beneficial mutations may confer traits that increase the fitness of a species, along with ensuring survival by conferring a protective advantage- these phenotypic differences between organisms are called adaptations.
Sequences of DNA make up genes which can have different forms called alleles. DNA, which makes up the genotype, is transcribed into mRNA and later translated into amino acids which are linked together by rRNA to form proteins which make up the phenotype of an organism.Mutations in DNA sequences affect the corresponding mRNA and thus the protein encoded.

Answer:
Option (C).
Explanation:
<em>Borrelia burgdorferi </em>is the bacterial species that causes lyme disease in the organisms. The researcher that discovers the <em>Borrelia burgdorferi </em>was Willy Burgdorfer.
The <em>Borrelia </em>has the ability to evades the body's defense. This species has antigenic variation and contains the enzymes that contain manganese which increases its capability.
Thus, the correct answer is option (C).
