The possible consequence of ozone layer depletion on living organisms is greater exposure to ultraviolet radiation. So the correct option in regards to this question is none of the above. The right option given here is option "d". This increased amount of ground level ultraviolet radiation increase would create more amount of skin and lung cancer for people. yup
Correct answer: B). They can be transformed into any type of body cell.
The stem cell is the biological cell that has the ability to differentiate into other types of cell. These are always found in the multi-cellular organism. These cells are known to be the foundation of every tissue and organ in our body. Embryonic stem cell is pluripotent, it means they can give rise to every type of cell in the body.
Example: Hematopoietic stem cells that give rise to all type of blood cells like red blood cells, white blood cells etc.
Hence, the correct answer would be option B.
Answer:
hey have demonstrated that applying a mask to an optical beam to give photons a spatial structure can reduce their speed.
Explanation:
Answer:
Movement of a solvent (such as water) into a solution with a higher solvent concentration by means of a semi-permeable membrane (as from a live cell), which tends to equal solute concentrations in the membrane on both sides.
Explanation:
Osmosis, the spontaneous transition, distribution, or diffusion of water and other solvents over a semipermeable membrane. In 1877, a German physiologist, Wilhelm Pfeffer, researched the process, which is important in biology.
Osmosis is the passage of water down its concentration gradient, across a semi-permeable membrane. An everyday example is a plastic wrap in your kitchen: it allows air and water vapor to move across it, but no water or food. The membranes of cells are semi-permeable, too.
Answer:
They use the polymerase chain reaction.
Explanation:
- Polymerase chain reaction ( PCR) is a processof making numerous copies of a specific segment of DNA quickly and accurately.
- The polymerase chain reaction helps researchers to obtain the large quantities of DNA that are needed for various experiments and procedures in molecular biology, forensic analysis, evolutionary biology, and medical diagnostics.
