Answer:
Together, adenine and thymine compose 70% of the segment. This means that 30% of the section is composed of guanine-cytosine pairs. Since these two bases will be equal in quantity, 15% of the DNA section will be cytosine bases.
Explanation:
I believe it is because kinetic energy is speed and temperature
Answer:
C) They differ in their genotype and in their phenotype.
Explanation:
Genotype refers to the genetic composition of an organism. It represents the gene and the respective alleles present in the genome of an organism. The genetic traits exhibited by organism due to the presence of a particular gene in its genome reflects the associated phenotype. Phenotype is the morphological expression of genotype.
The ability to synthesize histidine is a genetic trait. Bacteria not able to do so lack one or more genes that code the proteins involved in histidine biosynthesis. Here, the inability of histidine biosynthesis is the phenotype governed by the absence of the respective gene. Therefore, the bacteria unable to form histidine have different genotype and phenotype from the ones that can synthesize it.
