Answer:

The independent variable in the experiment is A. the jar covers.

Explanation:

The independent variable in an experiment represents the thing that the person conducting the experiment changes or alters.  One group in the experiment had covers (this represents the experimental group) and the other group had no cover (this represents the control group which was not exposed  to the independent variable).  Since the only thing that Redi changed between the two groups was whether or not the jars were covered, this represents the independent variable.

The number of jars and the contents of the jars were constant in both experiments, and the number of maggots on the meat is the dependent variable (the result of changing the independent variable).

Hope this helps!

Lady bird [3.3K]

Answer:

Mesosphere

Stratosphere

Trophosphere and Mesosphere

Stratosphere

Thermosphere

Explanation:

The Stratosphere

This extends upwards from the tropopause to about 50 km. It contains much of the ozone in the atmosphere. The increase in temperature with height occurs because of absorption of ultraviolet (UV) radiation from the sun by this ozone.

Troposphere

Earth’s troposphere extends from Earth’s surface to, on average, about 12 kilometers (7.5 miles) in height.

Mesosphere

Located between about 50 and 80 kilometers (31 and 50 miles) above Earth’s surface, the mesosphere gets progressively colder with altitude. In fact, the top of this layer is the coldest place found within the Earth system, with an average temperature of about minus 85 degrees Celsius (minus 120 degrees Fahrenheit).

Thermosphere

Located between about 80 and 700 kilometers (50 and 440 miles) above Earth’s surface is the thermosphere, whose lowest part contains the ionosphere. In this layer, temperatures increase with altitude due to the very low density of molecules found here.
