Common ancestry is identified in the genes. Selection forces are the drives to these physical and composition changes of an organism however, it can be traced back.
Adaptation processes occur to help species survive and thrive in the ecological balance of life. Structural adaptations are physical features of an organism that adapted through time. An example of this are the bills of a bird and the fur of bears that they generally need for their survival; birds for hunting, and bears to protect them from low climate areas.</span>
A DNA molecule is made up of nucleotides.Each nucleotide is made up of a nitrogen base, a sugar molecule and a phosphate group. There are 4 nitrogen bases such as adenine and guanine known as purines, thine and cytosine are known as pyramidine. These nitrogenous base are arranged in a sequence attached to each other by hydrogen bonding into anti-parallel strands. Therefore, the structure of DNA is termed as the double helical model.
Osmosis is a process by which the molecules of a solute spread out from a region with a high concentration of the solute to a region with a low concentration.
Knowing this, since the highest concentration of the sugar solution is inside the cell...
B. Sugar will move out of the cell
The correct answer to this question is B. Some members of the Fugate family had a genetic condition called methemoglobinemia, that gave a blue color to their skin. The gene causing this disease is an autosomal recessive gene, so to have this condition you need to be homozygotes for this recessive gene. Gene flow was prevalent in the Fugate family since not all of the children had blue complexion, but only four of them. The three children that did not have blue complexion, had the dominant allele, probably through gene migration from another population nearby. Also, since it is easier nowadays to travel, two separate populations could meet more easily. This increases the incidence of gene flow and explains the reduction of the occurrence of the condition.
