Answer:
In the nitrogen fixation process, nitrogen fixing bacteria converts the N2 in the atmosphere into NH3 (ammonia). This bacteria binds hydrogen molecules with the gaseous nitrogen to form ammonia in the soil. ... From the conversion of ammonia to nitrites, bacteria also aids in this process called nitrification
Explanation:
The correct option is this: THERE IS MORE BIODIVERSITY IN THE SUBLITTORIAL ZONE COMPARE TO THE UPPER INTERTIDAL ZONE BECAUSE THERE IS LESS TEMPERATURE VARIATION IN THIS REGION.
The sublittorial zone refers to the part of the ocean that is about 200 meters away from the surface. The zone is characterized by constant temperature as a result of the constant sunlight that reaches the depth; this leads to more biodiversity in this zone.
Answer:
None of these.
Explanation: The plants like cycads and ginkgos have swimming sperms. they need water to complete their life cycle.
There are many adaptations seen in the plants like liveworts, ferns and mosses in which they require water to complete its life cycle. This adaptation is not only restricted upto cyptograms. This can also be seen in the plants like ginkgos and cycads. Their sperms are very strange.
Answer:
Mitosis:
Mitosis has 4 stages total and produces 2 diploid daughter cells. The purpose of mitosis is for cellular proliferation. Since we only get 2 daughter cells, the chromosome number remains the same and generic variation doesn't occur.
Meiosis:
Meiosis has 8 stages total and produces 4 haploid daughter cells. In the shortest nutshell, meiosis is mitosis but twice. The purpose of meiosis is sexual reproduction. Since we get 4 daughter cells, the chromosome number is halved and generic variation does occur.
