The point of the experiment has been foiled by the choice to hand water one group and use sprinklers on the other. Whether talking to the plant or not did anything can't be proven because of this. If the student were to try to publish this experiment and the outcomes. Critics would be able to use the unequal treatment in water supply as a reason to discredit his/her experiment and dismiss the claims. When performing an experiment like this it is very important to treat each side as equal as possible.
Amino acids are the building blocks of protein
Answer:
C. Maximum power point tracking.
Explanation:
A. Direct current: It is also called DC in which electric current flows consistently in one direction.It is used in batteries and cells.It is not used in solar system .Therefore, it is false.
B. Alternating current : It is also called AC . The AC is used in domestic electricity.The current in which direction of electron is reversed after at regular intervals .It is not used for solar cells.Hence, it is false.
C. Maximum power point tracking:It is also called power point tracking. It is used in charge control in solar cells.it is a technique which is used to extracting maximum available power from PV ( photovoltaic cells) solar system.It is a technique that is used to adjust load connected to solar cells and increase their energy output.Therefore, it is true.
D. Electromagnetic induction:It is a process for producing EMF due to change in magnetic field. It is not used in solar system. Therefore, it is false.
Answer:C. Maximum power point tracking.
The primary concern of the scientist in clinical trial is patient safety.
A clinical trial is one of the final stages of any research process according to the requirement. Studies are done to find if the approach of the research and treatment is effective.
Clinical test or trial on human beings is done only after the pre-clinical phase which involves laboratory studies on animals (in vitro) to check the safety and efficiency of the drug. Animals are quite different from humans so human clinical trials are required to be done.
The main aim of clinical trial involves three major things to be considered: if the drug is working, the efficiency of the drug as compared to the currently present drug and most importantly that the drug is safe for human use and the patient is safe after the administration of the drug into the body.
The Earth rotates constantly and is exposed to the sun in different intervals & time periods - Thus, people need to establish a time zone to state when & where the sun rises as well as sets during daytime. <span>
