Differentiate between the three major climate zone

Answers

Answer:

tropical, temperate, and polar

The three major climate zones are tropical, polar, and temperate.

What are the climate zones?

A larger pattern, which helps one to understand weather is known as climate. The climate of the region is predicted by the average weather in the location over a long time duration. The three prime climate zones of the Earth are:

TropicalTemperatePolar

The climate region close to the equator with warm air masses is called tropical. In this climate zone, the average temperature in the coldest month is 18 degree C. This is warmer in comparison to the average temperature of the warmest month in the polar zone.

The polar climate zone is found in the North and South poles due to adjacent cold air masses. In this zone, the warmest months average is less than 10 degree C. This is lesser in comparison nto the average temperature of the coldest months in the tropical zones.

The climate zone situated between the North and South poles and the equator is the temperate zone. The average temperature of the coldest months in the temperate zone is lesser in comparison to the tropical zones, while the average temperature of the warmest months in the temperate zone is more than that of the polar zone.

Thus, the three major climate zones are tropical, polar, and temperate.

Cathy placed a sample of yeast , a single celled eukaryotes, in a closed test tube containing a solution of glucose. How will the composition of the air in the test tube change as the yeast interacts with the glucose

Answers

Yeast is very similar to human cells in that we have the same cellular respiration process. The formula for cellular respiration is C6H12O6(Glucose) + O2(Oxygen) = CO2(Carbon dioxide) + H2O
Because of this we know that the yeast is going to take oxygen from the air and the glucose in the test tube and produce carbon dioxide with it, so the full answer would be “The composition of the air in the test tube would change so that there is a higher composition of CO2.” If you need to explain it more pull from my explanation :)

Answers

Answer:

Mutation

Explanation:

The main cause of variation within a population is usually through genetic mutation.

Mutation is the alteration of the genetic sequence within an organism. It often lead to formation of new genetic patterns and codes.

Most times, environmental influences are paramount to causing genetic mutation within a population.

Other times, it might be due to competition and some other internal factors.

Mutation can be transferred from parents to offspring in most cases.

Which gas is most effective in absorbing incoming harmful ultraviolet radiation in the earth's stratosphere before that radiation reaches earth's surface?

Answers

Answer:

Ozone (O₃) gas

Explanation:

In the Earth's stratosphere, oxygen gas (O₂) is combined with atomic oxygen (O) to form ozone gas (O₃). This is very important because ozone protects the life on Earth from ultraviolet (UV) radiation from the Sun. UV radiation is high-energy radiation, and it is very dangerous for living organisms. Ozone molecule (O₃) absorbs UV radiation and it breaks down by forming O₂ and atomic oxygen (O) again. In this way, it protects the Earth from nocive radiation.
