Answer:
cells specialize to form specific tissue and organs because all cells have the same DNA. stem cells can develop into every type of cell inside the body.The cell is the basic unit of structure and function in all living organisms.
Answer:
Temperature is usually uniform throughout a cell (Ans. C)
Explanation:
Heat or thermal energy is a kinetic energy. That is connected with the random movements present in the atoms. Temperature is usually uniform throughout the cell so the most cell can not harness heat to perform work.
Heat is a type of energy which is transfer from one body to another body due to the temperature difference.
It can only perform work if it is transferred from one source which is warmer to a body which is cooler. The temperature in living organisms is usually kept very constant due to the process of homeostasis.
Answer:
False.
Explanation:
Note that, osmosis is considered as the passive movement of water because,it involves the movement of water from a region or area where concentration is high to the region or area of low concentration. This is the reason why it is compared to or described as a type of diffusion.
This process is known as passive transport or passive movement of water. And it is known to be water specific process.
That is why it can be compared to diffusion of ions or other small molecules in physics.
I think 75% or 90% (I looked it up lol)
