Plant cell walls are composed of cellulose, while fungal cell walls are composed of chitin. a group of scientists hypothesize that this difference means the cell wall has largely different functions in plant cells and fungal cells. alternatively, another group of scientists hypothesize that despite their biochemical differences, plant and fungal cell walls serve similar functions.

which of the following observations would best support the alternative hypothesis described above?

a. plant cell walls are found just outside the plasma membrane, while fungal cell walls are found just beneath the plasma membrane.
b. in both plant cells and fungal cells, the cell wall surrounds the outside of the cell membrane.
c. some plant cells have secondary cell walls that confer additional rigidity, while fungal cells do not.
d. photosynthesis occurs in plant cells, but it does not occur in fungal cells.

b. In both plant cells and fungal cells, the cell wall surrounds the outside of the cell membrane.

Explanation:

Both plants and fungal cells have a cell wall. In these cells, the cell wall is always present outside of the plasma membrane. Therefore, cell walls serve as the outer boundary of plant and fungal cells. In this way, the cell wall imparts mechanical strength to these cells. Plants and fungal cells can resist bursting due to endosmosis in the hypotonic environment due to the presence of a rigid cell wall. Therefore, cell walls in plant and fungal cells perform the same functions irrespective of their different chemical composition.

what following? you said which of the following. but there is no be more specific.

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 !
