The surface area-to-volume ratio of cells determines how quickly they can absorb materials. suppose that a space mission to planet zognard-42 uncovers giant cube-shaped single celled organisms living in an oxygen atmosphere. one species of cube-shaped organism is 2 cm on each side. another is 1 cm on each side. about how much faster will the smaller cube organism be able to absorb oxygen? a) 2 times b) 3 times c) 6 times d) they will absorb at the same rate.

species one has a sa of 24 (2*2*6) and a volume of 8 (2*2*2) so I'll make that a ratio of 1:3

species two has a sa of 6 (1*1*6) and a volume of 1 (1*1*1) so I'll make that a ratio of 1:6

2*3=6 so it will absorb oxygen twice as fast

Option , A Smaller species  will absorb oxygen 2 times faster than the larger species.

Explanation:

The amount of material absorbed by cells is directly determined by the surface area-to-volume ratio of cells.

A)Species 1 is of cube shape with sides of 2 cm

B)Species 2 is of cube shape with sides of 1 cm

Now we will evaluate the surface area-to-volume ratio for both the species

1) Species 1 -

Volume of a cube is

Surface area of a cube is

surface area-to-volume ratio

Here

surface area-to-volume ratio  for species 1 is

1) Species 2 -

Volume of a cube is

Surface area of a cube is

surface area-to-volume ratio

Here

surface area-to-volume ratio  for species 1 is

Species 2 (the smaller one) will absorb oxygen 2 times faster than the larger species.

Hence, Option A is correct

correct answer: understand the different control methods available

integrated pest management is an strategy that is based on the ecosystem and try to prevent the pest and the damage caused by them by applying combination of technique like habitat manipulation, biological control and use of resistant varieties.

the main aim of the integrated pest management is not to completely eliminate the pest but to strengthen the ecosystem so that conditions are favorable for plants and unfavorable for pests.
