Abotanist scrapes pollen off a flower of one plant and then uses it to pollinate the flower of another plant. what can be scientifically concluded about their offspring? a. they will have a large amount of genetic variation. b. they will have twice the number of chromosomes as their parents. c. they will be genetically distinct from their parents. d. they will be able to reproduce only asexually.

The correct answer is option A, They will have a large amount of genetic variation

Reason -

The transfer of pollens from the flower of one plant to the flower of another plant,  is termed as cross pollination.  

During cross pollination, two major instances can occur –

a)The transferred pollens may be of wild nature  due to which fertilization of eggs do not take place .

b)The transferred pollens  can fuse with the egg of the parent plant and results into offspring’s that shall carry the characteristics of both the genetically distinct plants thereby producing hybrid plants.

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 !
