The results shown in the picture were obtained using a technique known as gel electrophoresis. This technique separates mixtures of DNA. In the picture nine different samples of DNA are compared. Gel electrophoresis can be used to — correct answer: identify how closely two individuals are related The graphs show the reaction rate for an enzyme across a range of temperatures and pH. Based on these data, this enzyme functions best at what temperature and pH? correct answer: Temperature o...

Where do all cells come from? correct answer: Cells that already exist. The maximum population of a particular organism that a given environment can support without detrimental effects. correct answer: Carrying Capacity a mature sexual reproductive cell, as a sperm or egg, that unites with another cell to form a new organism. correct answer: Gamete the cell produced by the union of two gametes which are the sex cells. This is the 1st cell of the organism. correct answer: Zygote T...

Active Transport correct answer: Process requiring energy for the movement of particles across a cell membrane against the concentration gradient. ADP (Adenosine Diphosphate) correct answer: An organic compound that is composed of adenosine and two phosphate groups. With the addition of another phosphate group, it is converted to ATP for the storage of energy during cell metabolism. It then forms again, from ATP, when a phosphate group is removed to release energy. Amino Acids correct an...
