Answer:
A desert and a tundra are similar in that both of these regions receive little precipitation, have somewhat limited vegetation and experience cold temperatures at night. Cold deserts have long winters and cold temperatures. The tundra is cold with permafrost soil, which is not hospitable to plant life.
Explanation:
<u>ANSWER:</u>
The correct options are: B- "Full employment is a macroeconomic goal" and D- "Inflation is the rise in the prices of goods and services".
<u>EXPLANATION</u>:
- Macroeconomics studies issues like employment, inflation, poverty, unemployment etc. and so the goals of macroeconomics deal with all such issues.
- "Full employment" refers to a 'situation' wherein every individual who has the capability to work and earn is provided with a job. Inflation is the "rise of prices" of services and goods .
- Inflation makes it impossible for most people to buy even the necessary goods and services. Inflation also affects the demand of "goods and services".
Particulate material that quickly loses its energy as it travels through the air, has limited penetrating power, and can be stopped by clothing or a sheet of paper is known as <u> alpha particles</u>
<h3>What is penetrating power of radiation?</h3>
The ability of each type of radiation to penetrate matter is expressed by its ability to penetrate. The more radiation a material passes through, the greater the penetration power and the more dangerous it is. In general, the greater the mass current, the greater the ionization strength and the lower the penetrating power.
Comparing only three common types of ionizing radiation, the alpha particle has the largest mass. Due to the large mass of the alpha particle, it has the highest ionizing strength and greatest tissue damage potential. However, the same large size of these alpha particles makes them less likely to penetrate matter. Alpha particles have the least penetrating power and can be stopped by a thick sheet of paper or even a layer of clothing. They are also blocked by the outer layer of dead skin on the body. This seems to remove the threat of alpha particles, but only from outside sources.
