What is your opinion on Global Warming?
PolarNik [594]
My opinion is that EVEN IF there is anything that humans can do to save our species,
we will argue, debate, play politics, bask in absurd conspiracy theories, fritter around,
dilly dally, and totally ignore the urgency before us, until a time when nothing we're able
to do can any longer have any effect.  And that's my opinion.

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.

A pregnant woman found a large variety of microbes that can be vertically transmitted. She is making a list for her doctor to as
natta225 [31]

Answer:

Hyphae: Cell filaments,mostly septate

Mycelium: Mass of hyphae

Molds: mostly filamentous, Yeasts: non-filamentous,unicellular fungi

Budding yeasts divide asymmetrically.

Dimorphic fungi: yeast-like at 37°C, mold-like at 25°C.

Fungal spores are reproductive spores (unlike bacterial spores). Used to differentiate fungi.

Growth in acidic, low-moisture, high osmotic pressure environments.

The thallus (body) of a mold or fleshy fungus consists of long filaments of cells joined together; these filaments are called hyphae. Hyphae can grow to immense proportions. The hyphae of a single fungus in Oregon extend across 3.5 miles.

In most molds, the hyphae contain cross-walls called septa (singular: septum), which divide them into distinct, uninucleate (one-nucleus) cell-like units. These hyphae are called septate hyphae. In a few classes of fungi, the hyphae contain no septa and appear as long, continuous cells with many nuclei. These are called coenocytic hyphae. Even in fungi with septate hyphae, there are usually openings in the septa that make the cytoplasm of adjacent "cells" continuous; these fungi are actually coenocytic organisms, too.

Mycelium a mass of long filaments of cells that bring and intertwine, typically found in molds.
