Aman is 1.7 m long. a paramecium is 85 µm long. how does the length of the man compare to the length of the paramecium? a. the man is five (5) times larger than the paramecium. b. the man is five (5) times smaller than the paramecium. c. the man is twenty thousand (2 x 104) times larger than the paramecium. d. the man is twenty thousand (2 x 104) times smaller than the paramecium.

Answer is C. The man is twenty thousand (2 x 10⁴) times larger than the paramecium.

1 meter (m) = 10⁶ micrometers (µm)

Therefore, 1.7 m = 1.7 × 10⁶ µm

Thus, the length of the man compared to the length of the paramecium will be

1.7 × 10⁶ / 85 = 2× 10⁴ .  

Therefore, length of the man is  2× 10⁴ times larger than the length of the paramecium.

The correct answer is option C.

Explanation:

The given question requires the knowledge of the standard unit meter. By convention, the meter can be converted into micrometers in order to come to the conclusion. 1 meter is equal to 10⁶ micrometers. Thus, 1.7 meters = 1.7 × 10⁶ micrometers.  

There is a need to divide the height of the man with the length of the paramecium, which is 85 micrometers long.  

Therefore, the length of the man in comparison to the length of the paramecium will be:  

1.7 × 10⁶ / 85 = 2 × 10⁴

Hence, the length of the man is 2 × 10⁴ times larger in comparison to the length of the paramecium.  

then that particular organisms become extinct.

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 !
