1 answer:
user100 [1]3 years ago
4 0

Answer:

The answer is D.

Explanation:

Only 11% of freshwater is in swamps, so option A is incorrect.

The groundwater on earth appears to be a fraction of the freshwater, so option B is incorrect.

We can see that only 3% of the Earth's water is freshwater, so option C is incorrect.

68.7% of Earth's freshwater is found in icecaps and glaciers, meaning it is the majority of Earth's freshwater. Therefore, option D is correct.

How do eumelanin and pheomelanin affect our skin color?
KonstantinChe [14]

Answer:

There are two types of melanin--eumelanin and pheomelanin. In general, the more eumelanin in your skin, the darker your skin will be. People who make more pheomelanin than eumelanin tend to have lighter skin with freckles. Like many other traits, the amount and kind of pigment in your skin is controlled by genes

What is it called when two hormones cancel each other out or have opposite effects?
mina [271]

antagonism

When two hormones cancel each other out or have opposite effects it is called antagonism.

<h3>What is an example of antagonism?</h3>
  • Traditional examples of antagonistic hormones include insulin and glucagon.
  • In contrast to glucagon, which stimulates glycogenolysis, or the conversion of glycogen to glucose, insulin stimulates glycogenesis, or the conversion of glucose to glycogen.

<h3>What does the term "antagonistic hormones" mean?</h3>
  • Antagonistic hormones are those that work to bring body circumstances back from extremes to within acceptable bounds.
  • An illustration of how the endocrine system maintains homeostasis through the action of antagonistic hormones is the regulation of blood glucose concentration (by negative feedback).

<h3>How do antagonists to hormones function?</h3>
  • Infertility, endometriosis, and uterine fibroids are just a few of the diseases that gonadotropin releasing hormone (GnRH) antagonists are used to treat in women.
  • GnRH is a hormone released by the hypothalamus that is the target of GnRH antagonists, which stop it from functioning.

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.
