Answer:
1. meiosis 2. meiosis 3. meiosis 4. Binary fission 5. mitosis and meiosis 6. mitosis 7. meiosis 8. mitosis and meiosis 9. mitosis 10. Binary fission 11. meiosis.
Explanation:
The process of mitosis ad meiosis is a type of cell division that occurs in eukaryotes. The type of cell division in prokaryotes including bacteria is the binary division in that they do not have nucleus.
Mitosis is a type of division that produces identical diploid cells as the parent diploid cell. It involves only one division and involved in replacement of damaged tissue and for growth and development.
Meiosis is a type of cell division that produces unique daughter cells with genetic variation as a result of genetic recombination that occurs in the crossing over event in the interphase 1 of meiosis. This type of division involves two division (meiosis II and II) and also produces haploid cells. The parent cell is a germ line cell that was first diploid and then undergoes this form division producing haploid cells to be transferred to offspring.
Answer is A. A population becomes separated by environmental factors into two groups that do not reproduce with one another.
When a population of a species become geographically separated then gene flow between them stops. Over a period of time, the population may become genetically different in response to the natural selection due to different environments. Selection and genetic drift will act differently on these two separated populations. This will results into two separate species. This type of speciation is called allopatric speciation.
2. A
3. D (got cut off but the others don’t seem right)
4. D
Hopefully these are correct
Trophic level: the feeding level of an organism in a food web or chain. Food web: a diagram showing a series of interconnected food chains and the flow of energy through an ecosystem. Food chain: a diagram showing the flow of energy from one trophic level to the next. E.g. Consumer or decomposed Consumer: an organism which feeds on other organisms to obtain its nutritional requirements (part of a food web/chain). Producer: an organism capable of trapping the suns energy and converting it to sugar in the process of photosynthesis. Therefore the term food web is the term used to include all of the above.
hope this helps, :)
