DNA Replication begins at the Origin of Replication
Answer:
Letter b. Gluconeogenesis
Explanation:
Immediately after eating we use the sugars in the food and utilize for energy and last a couple of hours. After that and about 15 hours later our body uses the energy stored in the liver in the form of glycogen, a process called glycogenolysis, that is the action of breaking the glycogen to free the energy. After 24 hours, the body starts to use another molecule for energy like fatty acids and start to synthesize glucose from other precursors, this process is called gluconeogenesis, and fuels the vital organs like the brain to maintain its function.
Answer:
Antibiotic resistance evolves naturally via natural selection through random mutation, but it could also be engineered by applying an evolutionary stress on a population. Once such a gene is generated, bacteria can then transfer the genetic information in a horizontal fashion (between individuals) by plasmid exchange
The statements of the old cell theory are:
1. All organisms are composed of cells
2. The cell is the basic unit of life
3. Cells are produced from existing cells
The modern cell theory's statements are:
1. The cell contains hereditary information which is passed to daughter cells
2. All cells are basically the same in composition and activity
3. All basic functions occur in cells
4. Cell activities depend on intracellular structures
As is visible from the statements, the old cell theory was not as detailed and lacked the understanding of the function, structure and behavior of cells that the current theory possesses. This difference has come about after years of research, through which scientists understood the functions of cells and elaborated on the theory's statements.
