Amoeba proteus is injected with a drug that inhibits the formation of microtubules. what effect will this have on the organism's movement? a. it will die, and thus will not move. b. it will survive, but it will not be able to move. c. it will show hyperactive movement. d. the drug will have no effect on the organism's movement. e. it will only be able to move in one direction.

B.

Explanation:

Microtubules aid in movement by controlling chemotaxing of the pseudopods which are extension of the cytoplasm and they aid in movement. When microtubules formation are inhibited, the pseudopods will not function properly and thus movement will cease

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 !

the "dirty dozen" chemicals banned in an international treaty are formally known as persistent organic pollutants, or pops. the united nations environment program provided this background on what they are and what they can do to humans and wildlife.

i hope this
