Which of the following survives a temperature of $104^{\circ} \mathrm{C}$ to $106^{\circ} \mathrm{C}$
1 Marine Archaebacteria
2 Hot water spring thermophiles
3 Seeds of angiosperms
4 Eubacteria
Explanation:
Thermophiles - Thermophiles are microorganisms that grow at high temperature of $55^{\circ} \mathrm{C}$ or more. - Some micro organisms grow in very high temperature $\left(80^{\circ} \mathrm{C}-113^{\circ} \mathrm{C}\right)$ are called hyperthermophiles.

Bacteria are essential in carbon cycle as :
1 Decomposer
2 Synthesizer
3 Consumer
4 Primary producer
Explanation:
Bacteria are mostly decomposers in the carbon cycles. Bacteria sustain life by their ability to decompose plant and animal bodies, replenishing the limited amount of carbon dioxide needed for photosynthesis. As a result, they act as carbon decomposer in the carbon cycle. - The decomposers are bacteria, fungi and insects.

According to five kingdom system, blue-green algae belongs to
1 Metaphyta
2 Monera
3 Protista
4 Algae
Explanation:
Blue green algae belongs to kingdom Monera. The Monerans are unicellular, prokaryotes which lack well defined nucleus and other membrane bound organelles. - Blue green algae, also called Cyanobacteria, are heterogeneous prokaryotic organism. - They are considered the first organism to release oxygen. - They are believed to be organisms to convert reducing atmosphere to oxidizing atmosphere, as they have chlorophyll, cyanobacteria believed to be developed by endosymbiosis.

Non-symbiotic nitrogen fixing bacteria :
1 Rhizobium
2 Azospirilium
3 Azotobacter
4 Nitrosomonas
Explanation:
Azotobacter is a heterotrophic and aerobic bacteria which converts nitrogen gas into ammonia, form by the process of nitrogen fixation. - They do not reside inside the root nodules of the plant rather they exist freely in the soil. It is a diazotrophs. - Rhizobium is a genus of bacteria associated with the formation of root nodules on plant. These bacteria live in symbiosis with legumes, they take in nitrogen form the atmosphere and pass it on to the plants. - Nitrosomonas is a gram-negative bacteria which oxidized $\mathrm{NH}_{3}$ into Nitrite.

DNA of E.Coli :
1 ds circular
2 ss circular
3 ds Linear
4 ss Linear
Explanation:
E. coli bacteria are comes under prokaryotes. The DNA of E.coli is double-stranded and circular. The nucleic acid is usually double stranded DNA (ds DNA). - It is an important species in the field of biotechnology and microbiology, where it has served as the host organism for the majority of work with recombinant DNA.
