This infective protist belongs to the group A) Apicomplexa B)Archaeplastida D) Oomycota E) Ciliophona C)DinoflagellataExplanation / Answer
Ans 13. Those bacteria are called as heterotrophs and chemotrophs since there is something missing in the options hope you will get the answer after knowing the basic idea.
Chemotrophs :- are those which obtain energy from the chemicals as carbon is a chemical therefore the prokaryote is a chemotrop and heterotrop.
Ans 14. (d) 2 and 3. plasma membrane is present both in bacteria as well as archea but they both lack nuclear envelope.
Ans 15. (a) extreme halophiles.
Halophiles are the organism that live in high salt concentrations and are thus salt loving therefore the correct option is extreme halophiles.
Ans 16. (b) flagella and a lack of mitochondria "Giardia is an example".
Diplomonadida are the species which lack mitochondria and glogi apparatus they contain multiple flagella which are arranged symtrically.
Ans 17. (c) Dinoflagellata.
