Answer:
Option C
Explanation:
Dr. Leland Hartwell used baker’s yeast, <em>Saccharomyces cerevisiae</em>, as a model system, which was a highly suitable model for cell cycle studies. He introduced the concept of Checkpoints where he said cells are arrested if damaged so that the cells repair system can work to correct such damages. Dr. Paul Nurse used a different type of yeast, <em>Schizosaccharomyces pombe</em>, a type of yeast distantly related to the baker's yeast as a model organism.
Answer: They move against the concentration gradient
Explanation: This is because, with active transport, the molecules go from a low concentration to a high concentration.
The process of genetic engineering has been utilized to create this drug.
Genetic engineering is the artificial modification of DNA or other nucleic acid molecules in order to alter an organism’s characteristics in a certain way using biotechnology. Genetic engineering is used by scientists to improve or change the genetic makeup of an individual organism and it involves the transfer of genes to create ameliorate organisms.
A fossil would from through mineral replacement by replacing the existing material of the animals bones with minerals, to become petrified. The Minerals will keep the fossil preserved longer.
Have a good day!!
A compound is organic if it contains carbon covalently bonded to other atoms. Most often, the other atoms include hydrogen, oxygen, and/or nitrogen. A few carbon compounds, such as simple oxides (e.g. CO2) and cyanides (e.g. KCN) are excluded arbitrarily.
