Why would a red blood cell

Biology
1 answer:
Semmy [17]2 years ago
4 0

Answer:

RBC burst when placed in pure water , Ans C -The water rushes into the cell. Cell swells and burst.

Explanation:

This can be understand by understanding OSMOSIS

      Movement of water molecule from its higher concentration to its lower concentration through a semipermeable membrane is called OSMOSIS.

If cell is placed in any solution in which solute concentration is higher than inside the cell (HYPERTONIC SOLUTION), means water content in cell  is higher then outside environment. Then the water molecule will flow from cell to the outer medium. Water molecule movement continues till concentration of solutes reaches same both in cell as well as in medium.

IF cell is placed in any solution having solute concentration lower than inside   the cell. In this solution water content will be higher and solute concentration will be low (HYPOTONIC SOLUTION). Water movement will be inside the cell from the outer environment.<u><em> As the result Cell swells and ultimately burst because of excess water content.</em></u>

IF cell is placed in ISOTONIC SOLUTION, where concentration is same both  in cell and outer environment, No movement of water molecules takes place.

choli [55]

Answer:

these seemingly dissimilar organisms might have evolved from a distant

Explanation:

Evolution deals with history of organism survival on Earth.

The evolutionary biologists makes use of fossils as proves to give light to having a clear view of how species survived in past times.

Before the theory of natural selection by Charles Darwin, Evolutionary Biologists were filled with questions about why the type of skeletal structural specimens collected were equal and different in dissimilar organisms as it does not exhibit the links seen between these species.

The theory of evolution proposed the mechanism of divergent evolution as a solution to these questions.

Therefore, we conclude that "these seemingly dissimilar organisms might have evolved from a distant" is the right answer.

Which description accurately compares cellular respiration and photosynthesis?
Genrish500 [490]

Answer:

The correct answer will be option-A.

Explanation:

Photosynthesis is a process which uses sunlight energy to synthesize food in the form of glucose. The process takes place in the chloroplast in two stages: light-dependent reactions and light-independent reactions.

The light-independent reaction produces to convert the carbon dioxide from the atmosphere to glucose through the Calvin cycle. The carbon gets fixed and reduced form+4 state to +1 state.

Respiration is the process which oxidizes the glucose molecule to produce energy in the form of ATP molecules. This ATP is utilized by the cell to perform various functions.

Thus, option-A is the correct answer.
