Bcoz.. In meiosis ti change ploidy of cell from diploid(n) to haploid(2n) .. 2 division occur.. This helps in formation of haploid gametes.. When two gametes fuse.. They form diploid (2n) zygote.

On the other hand..

There is only one division in mitosis...bcoz no change in ploidy.. Use in growth. Bcoz it retains nucleo-cytoplasmic ratio.

Answer:

It is important because plants respond to light depend, logically enough, on the plant's ability to sense light. Phototropism is a directional response that allows plants to grow towards, or in some cases away from, a source of light. Photoperiodism is the regulation of physiology or development in response to day length.

Which of the following statements is true?
Free_Kalibri [48]
<span>The answer would be: a) Frost-wedging happens when water freezes and breaks rocks.

Normally, the volume of a substance will become lower when the temperature drops but when water becomes ice it will expand. Water that freezes into ice can produce a high pressure from the expansion of their volume. If enough water fills a joint in a rock, the rock might get enough force to fractured or break. This will happens in the area that has a freeze-thaw cycle like in the polar climate.</span>
