Answer: In order for cells to function and survive, these organelles work together to carry out specific tasks, and perform specific roles. Each organelle has its own role that contributes to the survival of the cell.
Explanation:
Answer
The random motion of molecules occurs when they are placed in any container any open space, they have freedom to move to and fro as well as from one point to another. The random movement of molecules do not needs any energy inputs and it occurs on its own.
Diffusion:
If we talk about diffusion, it is a process in which molecules move from an area of higher concentration towards an area of lower concentration. For example: When we spray a fragrance in one corner of the room, after some time it will spread in whole room because molecules will move from a corner of high molecular concentration to the place where they are less in number. This process occurs freely and without any external input of energy.
Osmosis:
If we talk about osmosis it is also a diffusion of molecule but across a selectively permeable membrane like plasma membrane of living cells. Just like simple diffusion it also donot needs any external energy inpuy.
What is common in all?
That all three types of molecular movements do not need any energy inputs from system and it occurs on their own, therefore all are related.
Hope it help!
Answer:
c. Factors 1 and 2 may be influenced by both nature and human factors
Explanation:
The sea level rising and the change in the atmospheric gases are both processes that are influenced by the nature, as well as by the human activities. Naturally, the earth has its own cycles, known as Milankovich cycles, through which the Earth warms up, or cools down, resulting in change of the atmospheric gases, and in accordance to that, change in the sea levels depending on the global climate. The humans to have become a big factor in the past few hundred years. The reason for that is that the humans with their activity started to release lot of greenhouse gases into the atmosphere, especially CO2 and methane. That has been changing the composition of the atmosphere, and the temperatures have been rising. The higher the temperatures, the more ice is melting around the poles and on the high mountains, resulting in an increase in the sea levels.
