Which of the following are likely impacts of converting natural grasslands into agricultural land, if that conversion occurs without attempts to mitigate its effects? ️ Note that there are 2 answers to this question.
Choose 2 answers:

A. Certain animal populations in the grassland ecosystem will get smaller due to habitat fragmentation, leading to a decrease in biodiversity.

B. Water containing fertilizer will drain from the agricultural lands, causing an overgrowth of algae in nearby lakes.

C. Crop plants will add to the genetic diversity of the region’s plant communities, making the communities less susceptible to disease outbreaks.

D. The grassland areas will have fewer native grasses and other resources, making it more difficult for invasive species to become established there.

the answer that best describes the relative refractory period in the neuron is the resting membrane potential is restored, but concentrations of sodium and potassium are not restored to their original state.

the refractory period is the time during which another stimulus given to the neuron will not lead to a second potential. thus, because na+ channels are inactivated during this time, additional depolarizing stimuli do not lead to new action potentials.

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 !

there are so many examples for that in different areas, like biology experiment carried out in our lab recently.
