Answer:
a. He is missing a control group of mice that did not receive the new antibiotic.
Explanation:
In any experiment especially experiments testing effectiveness of a drug, there should be a control group.
The importance of a control group is to minimize the effects of other variables other than the independent variable hence increasing reliability of the results.
in this case, a group of mice that did not receive the new antibiotic would have served as the control group.
All of the systems within the body interact with one another to keep an organism healthy. Although each system has specific functions, they are all interconnected and dependent on one another. The nervous system controls various organs of the body directly. The brain also receives information from many organs of the body and adjusts signals to these organs to maintain proper functioning.
Energy is transferred between the earth's surface and the atmosphere in a variety of ways, including radiation, conduction, and convection. The graphic below uses a campstove to summarize the various mechanisms of heat transfer. If you were standing next to the campstove, you would be warmed by the radiation emitted by the gas flame. A portion of the radiant energy generated by the gas flame is absorbed by the frying pan and the pot of water. By the process of conduction, this energy is transferred through the pot and pan. If you reached for the metal handle of the frying pan without using a potholder, you would burn your fingers! As the temperature of the water at the bottom of the pot increases, this layer of water moves upward and is replaced by cool water descending from above. Thus convection currents that redistribute the newly acquired energy throughout the pot are established
Answer:
b. become part of the body's structural systems.
Explanation:
- Minerals are the inorganic regulators needed for different functions inside the body.
- Minerals donot provide energy but involved in generation of energ through their metabolic function. (Hence option A is excluded)
- They provide a good medium for the protoplasmic activities (permeability of cell membrane and normal functioning of cell)
- Maintaining bod fluid balance.
- For structural units.
- Cannot be degraded in the body neither can be destroyed while cooking ( Hence option c and d are excluded)
- They become the part of the body's strctral systems (Hence option B is the right answer)
Answer:
Suillus lakei mushroom refers to a mycorrhizal fungus, which grows in company with Douglas fir, and can be witnessed in the locations where this tree is found.
This association illustrates a symbiotic relationship, known as mycorrhizae, which is produced between the plant and the fungi. The fungi colonize the root system of the host plant, in this case, Douglas fir, and provide enhanced nutrient and water absorption tendencies, while the plant offers the fungus with carbohydrates produced from the process of photosynthesis.
