What allows humans to have different traits from each other

Answer:

B: Hyperosmotic solutions may cause the cell to shrink.

Explanation:

Final answer:

The first statement is false because it inverses the concepts of potential and kinetic energy. The second statement is true, and the electric field is indeed analogous to the gravitational field. The third statement is false since voting rates in the U.S. are not higher than in most other democratic industrialized countries.

Explanation:

The answers to those statements are as follows:

1. False. The statement is incorrect because it inverses the concepts of kinetic and potential energy. When a rock is thrown into the air, its height increase adds to its potential energy, not kinetic energy. When it starts falling back to the ground moving faster, its velocity increase adds to its kinetic energy.
2. True. This statement is correct. The characteristics of an electric field indeed make it analogous to the gravitational field near the surface of Earth. Both fields decrease in intensity with the square of the distance from the source.
3. False. Voting rates in the United States are not higher than in most democratic industrialized countries including Sweden and South Korea. In fact, other industrialized countries often have higher voter turnout rates than the U.S.

Answer:

A. burning fossil fuels

Explanation:

Acid rain is caused, mainly by the emission of sulfur oxides and nitrogen oxides, which are gases commonly released into the atmosphere as a result of burning fossil fuels.

These oxides have the ability to interact with rainwater generating an acidic substance that is expelled from the clouds in the form of rain that has a very acidic pH.

The result of acid rain is the destruction of vegetables, the chemical alteration of water bodies, the death of aquatic animals, the contamination of groundwater and even the emergence of respiratory diseases and the destruction of public heritage.

Answer:

C. 5 km/h north

Explanation:

Speed is the rate at which an object changes position, and it is measured in meters per square seconds. The formula or equation used in calculating speed is distance divided by time. The distance traveled is always in meters and time is always in seconds to get the speed it will be one meter per second.  Speed doesn’t specify the direction at which an object will travel. Hence the answer is C. 5Km/hr north
