Setler79 [48]

Sulfur emissions from industry combine with water in the atmosphere and form acid rain. A new factory is built very close to the lake that Josh visits often. By examining the table that shows what pH range different species can survive, Josh decides that the aquatic life will be affected by the changes in pH that the lake. Josh correctly decides that organisms that will be the most affected are

A) perch and frogs.

B) mayfly and bass.

C) snails and clams.

D) frogs and salamanders.

The correct answer is option (C) snails and clams.

Acid rain is formed when oxides of sulfur and nitrogen combine with water molecules. Industries are one of the major contributors to acid rain. pH is a measure of acidity or alkalinity in water.

A factory built close to the lake can cause acid rain which affects the pH of the lake. Any change in the pH of the lake has an effect on the organisms in it. A pH of 7 is considered to be neutral and pH values below 7 indicates acidity and pH values above 7 indicates alkalinity. Organisms have an acid tolerance level beyond which they are affected and can die. Perch has an acid tolerance of up to pH 4.5 and frogs can tolerate an acidic pH of 4.0. The acid tolerance level of Mayfly and Bass is a pH of 5.5. Salamanders can tolerate an acidic pH of 5. Whereas, Snails and Clams have a very less pH tolerance of 6. They are highly susceptible to acidic pH.

Thus, Josh correctly decides that organisms that will be the most affected are snails and clams.

Ozone in the troposphere is necessary to protect Earth's surface from harmful UV radiation.
romanna [79]

Answer:

False

Explanation:

In the troposphere, near the Earth's surface, human activities lead to ozone concentrations several times higher than the natural background level. Too much of this ground-level ozone is 'bad' as it is harmful to breathe and also damages vegetation.

The stratosphere or “good” ozone layer extends upward from about 6 to 30 miles and protects life on Earth from the sun's harmful ultraviolet (UV) rays.

Lana71 [14]

Answer: option A) defining a business in terms of goods rather than the benefits customers seek.

Explanation:

As the name implies, myopia, relates to a short-sighted or immediate approach. Marketing myopia explains how a company directs its business activities such as production of goods and services BASED on its own needs rather than considering the demands of the consumers/customers.

This, in turns makes a company appear rigid and unable to respond to market dynamics such as inflation.
