the Galapagos
While visiting the Galapagos in 1835, British naturalist Charles Darwin observed local plants and animals.
The folds in the photograph above were caused by compression at a thrust fault or a convergent plate boundary. Compression usually occurs where two tectonic plates converge or collide. The compression will cause rocks to fold upwards and this upward folding over time can lead to the formation of extensive fold mountains. Examples of fold mountains include the Alps, Andes, and the Himalayas.
Answer:
Cells divide twice
Explanation:
Meiosis may be defined as the process of cell division in which a single cell divides to give four daughter cells and each daughter cells have half number of chromosomes.
Meiosis is also known as reduction division as the chromosome number reduces upto half in the progeny cells as compared with the parent cell. The cells divide twice in meiosis and give rise to four daughter cells.
Thus, the correct answer is option (4).
Tonicity in cells depends on both the concentration of solute outside the cell and the concentration of solute inside the cell
Tonicity is a concept used in biology that defines the osmotic pressure ( pressure that stops the fluids from entering or leaving cells). This pressure is defined by the concentration of solute (substances dissolved in the liquid) outside and inside the cell.
In this context, the cell is classified as isotonic if there is a balance between the concentration outside and inside; hypertonic if the concentration outside the cell is higher, which causes the cell to shrink of hipotonic if the concentration outside is lower, which causes the cell to swell.
