Answer:
Experiment
Explanation:
An experiment is conducted to test the activity of the caffeine in the blood stream of the athlete
This ensures that the experimenter can be certain that the variable they are testing is what causes a pattern in the data if there is a pattern.
Similarities:
Both involve ion movement. Both use ion channels to move ions across the cell membrane, in or out of the cell.
Differences:
Passive Transport (or Diffusion) moves ions from high concentration to low, using no metabolic energy. Active Transport moves ions from low concentration to high, using metabolic energy in the form of ATP. Active Transport uses an ion pump (or Sodium/Potassium pump) to move 3 sodium ions out of the cell and 2 potassium ions in to the cell through the energy of 1 ATP molecule.
In active transport particles move against a concentration gradient and therefore require energy which must be supplied by the cell. Carrier proteins that are found in the cell membrane of cells use energy to transport molecules or ions across the membrane, against the concentration gradient.
Passive transport is a naturally-occurring phenomenon and does not require the cell to exert any of its energy to accomplish the movement. In passive transport, substances move from an area of higher concentration to an area of lower concentration.
<span>The correct answer is C. Water vapor cools and condenses. Depending on the rest of the climate, this can either result in rains falling, sometimes even serious monsoons, or it can end in snow and hail which can be extremely dangerous for agriculture and cost countries millions of dollars of failed produce.</span>
The correct answer is C. Translation.
The given figure is the scheme of the gene expression. It provides the flow of genetic information from a DNA sequence to a protein synthesis inside cells. This process of flow of genetic information from DNA to RNA is called transcription and the process of flow of genetic information from RNA to protein is called translation.
Thus in given figure label A is to be replaced by transcription and label B is to replace by translation.
