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:
All organisms that have life, both plants and animals.
Explanation:
You didn't provide an illustration, but I guess I can still help. Biotic factor means that it has life, abiotic means it's not alive (hence the a- at the beginning.) Some biotic factors of a pond ecosystem include: earthworms, fishes, frogs, plants and insects.
Emigrated means they exited so due to the high amounts of pollution all the animals left which cause a population decrease
Prokaryotes divide by binary fission, a form of asexual reproduction in which a cell divides into two cells with identical genetic information.
Explanation:
Binary fission and mitosis can be viewed as the same principle of asexual reproduction to give out two identical cells. However, the major difference between the two is that binary fission is to prokaryotes and mitosis is to eukaryotes. Remember that prokaryotes do not have a true nucleus (they have a nucleoid) hence binary fission does not involve the dividing of the nucleus. Mitosis does.
Sexual reproduction is responsible for creating variation in offspring especially due to the process of meiosis in gamete development and subsequent fertilization of two gametes from different parents.

In order to study the formation of cancer cells, you should study the life cycle of normal cells as cancer cells are abnormal cells.
Actually, Normal cells grow, divides and died after an interval of time. And when this process is break down, cancer cells begin to form. They are usually old cells which don't die after their life cycle.
Hope this helps!
