A polar molecule is one that has an unequal distribution of charge. In short, the molecule is not symmetrical when you look at it. Does not need to have polar bonds

attashe74 [19]

Answer:

Option a, survive in extreme environments

Explanation:

Both Thermus and Deinococcus belong to the group of bacteria that are collectively termed as Deinococcus–Thermus group.

Deinococcus are radiation-resistant vegetative cell as they are able to resist ionising radiation. Also some species of Deinococcus are thermophile.

Thermus are thermophilic bacteria that are able to live in extreme temperature condition and thus are able to tolerate high temperature.

Hence, option A is correct.

Group the following into the appropriate range of measurement.
Vesna [10]

Answer:

Hydrogen atom & glucose molecule --- atomic.

Herpesvirus, DNA --- ultramicroscopic.

Protozoan, Rickettsia - microscopic.

Roundworm and algae --- macroscopic

Explanation:

1) Hydrogen atom & glucose molecule --- atomic.

The atomic size level, which interacts with atoms as well as small molecules, is much lower than the ultramicroscopic range.

2) Herpesvirus, DNA --- ultramicroscopic.

Ultramicroscopic particles are very tiny structures that cannot be seen using a conventional optical microscope, necessitating the use of an electron microscope. Viruses and DNA falls into this group since they are much smaller than tiny species like bacteria.

3) Protozoan, Rickettsia - microscopic.

Microscopic species are much smaller than macroscopic organisms because they cannot be observed by the naked human eye and must be viewed through a microscope. The size range for microscopic particles is ( 10^3  \ \ to  \ \ 10^{10}), which contains protozoans and Rickettsia (a gram-negative, non-motile bacteria genus).

4) Roundworm and algae --- macroscopic

Naked eyes can see macroscopic organisms; for example, several types of circular worms and algae can be seen by them.
