Answer:
Option A, Start the reaction by absorbing light energy
Explanation:
Chlorophyll is a green color pigment in plant that helps in entrapping sunlight. Being green in color, it absorbs the blue and red light and reflects the green light. The molecules of chlorophyll gains energy from sunlight and then jumps to higher energy levels by the process known as photo excitation. These excited molecules get ionized to further initiate the process of photosynthesis.
Hence, option A is correct.
The basic components (depedent and indepedent variables) are the plants and altitude while the confounding variable is the 20 story building. Confounding variables affect the experiement variable and are mainly outside of the researcher’s control in the experiment. Ray cannot change the building but this variable can affect the depedent and indepedent variables and cause distorted or spurious results.
The correct answer for the question that is being presented above is this one: "Each experiment reveals a different piece of information that is needed to develop the theory." Some theories are developed from repeated testing of a single hypothesis. Cell theory, germ theory, and the theory of evolution all have developed from <span>the testing of multiple related hypotheses.</span><span> </span>
Answer:
B. similar to the cells just treated with the dye - 0% dead
Explanation:
According to this question, an experiment was set up in which kidney cells were treated with a chemical for different amounts of time. Hence, the independent/manipulable variable is the CHEMICAL.
Based on the observation of the group of cells, a cell that has been damaged by the chemical will appear pink when treated with dye while a cell treated with only due but no chemical will not appear pink.
A NEGATIVE CONTROL is the group in an experiment that is not treated with the independent variable i.e. doesn't receive experimental treatment. Since the independent variable in this experiment is the CHEMICAL, the negative control will be the group that doesn't receive the chemical treatment. Hence, the negative control is similar to the cells just treated with the dye - 0% dead
This patient has has a medial epicondylar fracture of the humerus (part of the humerus that forms the elbow joint medially). The patient was treated surgically by either open or closed reduction of the elbow. In coding this particular disease, the most appropriate code to use is CPT 24565-54-RT and 24605-54-51-RT that encompasses "<span>Fracture and/or Dislocation Procedures on the Humerus (Upper Arm) and Elbow".
