Explanation / Answer

here will be explanation of each n every option which is given for a question pls read carefully

ans 1.) a option- they are actually more successfull other than any because life arise from them earlier only they were present on earth n you see at the end these will only survive

b option- it is correct on body and inside the body we have many more bacterias present even the air in which we live actually have millions of bacteria.

c option- bacteria is prokaryote so it dont have any nucleus at all

d option - there are mainly 3 domain present 1. is archaea 2. is bacteria 3. is eukarya bacteria may be from archaea and bacteria domain but eukaryote cell from domain eukarya.

so the correct option is 'B'.

ans 2) option a- if two species who are distantly different so they must have different or variation in their DNA sequence and vice versa

option b- two distantly different species never have similar DNA sequence

option c- two closely related species have similar DNA sequence not divergent or different as given in option d

so the correct option is 'a'

ans 3. option 'D' domains is not mainly arbitration based taxa.

ans4. option 'C' which indicate release of chemicals have best example you must know is penicillin which is first antibiotic produce from fungus penicillium notatm fungs and it is antibacterial other options regarding fungus is absolutely wrong

ans 5. option 'A' kingdom is considered as largest unit of taxonomy because it consist many number of organism.

ans6. option 'A' according to whittaker 5 kingdom classification oldest one was monera and then protists after it fungi, plants and then animalia.

ans 7. option 'd' pigs are mammals in that case they are similar to humans they are omnivorous mammals.

ans8. malaria is caused by protozoa plasmodium whose vector is female anopheles mosquito and it have been killed more than 2 million of people so option 'E' is correct.

ans 9. 'B' eukarya amoeba paramecium and euglena are single celled eukaryotic cells so it comes under eukarya domain.

ans 10. option 'B' phylogenetics is the study of evolutionary relatedness between species or genes or individual.

ans11. option 'E' gymnosperms are baked seed bearing plants as sexual organ they consist of cones like cycas and pinus .

ans 12. option 'e' homologous organs are those which has same ancestry but perform different function according to their need as birds fly and fishes swim.

ans 13. option 'd' fungus obviously have larger number of species it has 5.1 million species

insects have 950,000

fishes have 33,100

plants have 1,589,361

vertebrates have 59,811

protists have 2 million

birds have 9,956

hope it will help you....
