The spectra of the sun and stars exhibitee bright and dark lines called fraunhofer lines. Because each element absorbs light only at specific wavelengths, the chemical composition of stars can be determined.
The fertilization happens in our body with single cell and our body is form with same set of gene but with starting with single set of fertilized egg.
Explanation:
It reached to trillions of eggs. So, it is not possible to look same. The same thing happens with red blood cells, skin cells and nerve cells. Their size is different according to their work.
In our body the structure of all cell is totally different. Each and every cell is responsible for different work. Their size is according to their suitability of their job. For example, nerve cells are long because it helps to send the signals.
Answer:
The larger the amplitude of the waves, the louder the sound. The faster the vibrations, the higher the pitch (frequency) of the sound.
Explanation:
Answer:
Lose water and plasmolyze
Explanation:
- When a plant cell is placed in a solution with a lower water potential it will lose water osmotically and plasmolyze.
- During the process of osmosis water moves from a region of higher water potential to a region of lower water potential.
- <u>Loss of water by the plant cells makes it to shrink or reduce in size and consequently, the plasma membrane pulls away from the cell wall, producing plasmolysis.</u>
