Consider the following geometric solids a sphere with a ratio of surface area to volume equal to 0.08 M negative one a right cir

azamat

Options:

A. The rate of diffusion would be the same for the two models.

B. The rate of diffusion would be faster for the right cylinder.

C. The rate of diffusion would be slower for the right cylinder.

D. The rate of diffusion would be faster for the sphere.

Answers:

The rate of diffusion would be faster for the right cylinder. Thus, the correct option is B.

To begin with, we must comprehend how the ratio of surface area to volume affects the rate of diffusion.

When comparing the ratio of surface area to volume, a body with a larger surface area will have a higher rate of diffusion than a body with a smaller surface area. It can be expressed mathematically as:

V∝ R (whereas v is the diffusion rate and r is the surface area to volume ratio)

The answer to the question's surface area to volume ratio for spheres is given 0.8m⁻1

For a right circular cylinder, the surface area to volume ratio is provided is 2.1 M.

The right circular cylinder has a larger ratio, hence it is obvious that the right circular cylinder will have a higher rate of diffusion because the rate of diffusion is directly related to the surface area to volume ratio.

1) What surface characteristics affect the rate of heating and cooling?

matrenka [14]

Answer:

The color of the surfaces because an object with a black surface will absorb and reradiate energy faster and at a higher concentration than the same object with a lighter colored surface.

While distinctly Anthropoids, some Platyrrhines maintain a few of traits that are typically represented only in Prosimians. For

crimeas [40]

Convergent evolution is the concept of two or more species evolving similar traits despite being completely unrelated to one another, including the absence of a common ancestor.

The Platyrrhines, more commonly known as "New World Monkeys", share many characteristics with the Prosimians. Some of these include:

Teeth layout
Diet
Eyesight
Sleeping habits

and more.

The Platyrrhines and the Prosimians are both nocturnal animals. Despite all other members of their family being active during the day, the Playrrhines have evolved nocturnal habits similar to that of the Prosimians. Aside from that, they feed on insects more so than fruit, which is reflected by the layout of their teeth, and have eyesight well adapted to dark conditions. All of these are traits they share with the Prosimians.

Despite being in different ecosystems and regions, and sharing no recent common ancestors, both of these species have evolved strikingly similar traits. This can be used to corroborate the theory of convergent evolution, which explains how two species can evolve very similar traits despite being unrelated.
