Better spreading of reproductive cell is not a benefit of bioflims for bacteria.

Option: (d)

Explanation:

Bioflims can allow for adhesion of colonies, that can attach surface such as rock, tooth and it includes single or group of micro organism. Bioflim bacteria can share 'nutrients' and it is sheltered from 'harmful factors' in environment like desiccation, antibiotics, etc. It allow resistance for sanitation, that hold bacteria together and also exclude most disinfectant and antibiotics. It is resistant to sterilization.

Answer from: Quest

d concave shape of wave rock

explanation:

the concave shape of wave rock is a very good evidence that supports the evolution of earth due to chemical weathering. if we talk about structure of wave rock, studies have estimated that it is around 2.7 billion years old. it also serves as the foundation of evidence that it was the place where australian continent began to form.

how the structure of wave rock was created?

studies suggest that structure of wave rock was created when the surrounded area was started to weather due to which deposition of material started on the part of land which now contains wave rock.

the structure of wave rock is considered to be one of the best-known landforms in australia. at the height of around 15 cm, there can be found flared slopes which formulate the margins of hyden rock. it is now assumed by geologists that wave rock was created by subsurface water-induced weathering and not by glaciers, waves or wind.

due to deposition of material over the period of long time, the wave rock became tougher and tougher due to weathering from surrounding terrain. this makes it a physical evidence that supports the evolution of earth due to chemical weathering.

hope it !

Answer from: Quest

one is through turgidity. this occurs before ground tissue ( collenchyma

and sclerenchyma cells) become well

developed to give structural support to the plant as it grows bigger. the xylem

tissue (composed of rigid tissue) of the young

plant render this support and also maintaining osmotic turgidity of the surrounding

plant cells.
