Answer:
In a school environment, there are different teachers who teach a different subject, administration controls all the school functions and affairs other than teaching. Other staff such as janitors, bus drivers carry out necessary functions.
In the schools, there are various specific tasks carried out by specific teaching or non-teaching staff. In the cell, a similar condition found as they show specialization and communication as various cell organelles are specific to a specific function and communicate with one another.
A logarithmic model is the type of growth in which a population increases rapidly at the first, and then it starts slowing down to level off the population. This occurs due to plenty of resources available initially, when the population starts developing and then resources start to limit and competition occurs, which slows down the growth.
Answer:
C) Re-do the measurements, several times, and take the average density before making a decision.
Explanation:
For the correct identification of the metal, weather its nickel or copper, Carl should repeat the experiment several times and take the average density before making the decision. It is important because it reduces the chance of error and ensure the data integrity. The more the sample size is, lessen would be the error.
Answer:
B. A proton gradient drives the formation of ATP from ADP and inorganic phosphate via ATP synthase.
Explanation:
Light reaction of photosynthesis includes the splitting of water in the presence of sunlight and electron transfer from PSII to PSI via an electron transport system. During the transfer of electron through cytochrome of the electron transport system, the proton concentration gradient is generated across thylakoids. The proton concentration gradient is harvested to drive ADP phosphorylation by the catalytic site of ATP synthase accompanied by downhill movement protons through its proton channels.
