In which investigation would it be BEST to use observational data obtained outside of a laboratory rather than empirical data from controlled experiments?
an investigation to determine the amount of oxygen that an animal consumes while sleeping
an investigation to determine the genetic code of a harmful bacteria
an investigation to determine the structure of a protein
an investigation to determine the feeding habits of a species of bird
An investigation to determine the feeding habits of a species of bird
employs the use of observational data obtained outside of a laboratory.
Observational data outside of a laboratory is best suited for feeding habits
of a bird because it requires lower degree of control over the environment.
Feeding pattern doesn't require any special technique which is why it can be
done on the field.
Other options require the use of higher degree of control over the
environment to ensure accurate results are derived.

According to the map, which body of water was controlled by the Roman Empire?
the Red Sea
the Black Sea
the Caspian Sea
the Persian Gulf
The Mediterranean Sea was controlled by the Roman Empire which was not given in the options.
What is the Mediterranean Sea?The Mediterranean Sea is a sea connected to the Atlantic Ocean that is encircled by the Mediterranean Basin and nearly entirely surrounded by land on the north, Western and Southern Europe and Anatolia, on the south, North Africa, and on the east, the Levant.
In the history of Western civilization, the sea has played a crucial role. Although the Mediterranean is often included in the Atlantic Ocean, it is widely regarded a separate body of water.
According to geological data, the Mediterranean was shut off from the Atlantic approximately 5.9 million years ago and was partially or fully dry for 600,000 years during the Messinian salinity crisis until being flooded by the Zanclean flood about 5.3 million years ago.
The Roman empire was based on the unification of the Mediterranean Sea.The Romans, who lived in a little town on the Italian peninsula in the Mediterranean's western basin, had conquered the western basin first, and later the eastern basin of this nearly land-locked body of water.
Hence , the correct answer is The Mediterranean Sea.

2. With less space, populations decline.
3. Some animals need trees to survive.

2. Populations cant thrive if theres no where to have offspring.
3. Animals depend on trees for shelter and food. If there are no more trees, primary and secondary consumers would suffer.

We can think of electromagnetic waves as a kind of ongoing message being sent out by the universe. Humans are able to naturally access only a portion of this message.
What information from the passage best supports this statement?
a
The waves emitted by our physical world make it possible for us to communicate over vast distances.
b
The human eye is only sensitive to a portion of the electromagnetic spectrum.
c
Without light, we wouldn't be able to process the visible world.
d
Mankind has invented tools to harness the information contained within electromagnetic radiation.
Option (B) the human eye is only sensitive to a portion of the electromagnetic spectrum (visible lights) best supports above statement.
What are electromagnetic waves?Electromagnetic radiation is made up of electromagnetic field waves that travel through space carrying electromagnetic radiant energy. These waves are carried by electromagnetic radiation. Radio waves, microwaves, infrared, light, ultraviolet, X-rays, and gamma rays are all components of this spectrum. The electromagnetic spectrum is made up of all of these different types of waves.
We can only see a small portion of the electromagnetic radiation that exists, which is the portion that we refer to as visible light. However, all electromagnetic radiation is light. These cone-shaped cells in our eyes function as receivers and are tuned to the wavelengths that are present in this particular narrow band of the electromagnetic spectrum.

Explanation:
Pls pls tell me if im wrong, ill do my best to fix it
B. Interaction with other organ systems.
What is an organ ?An organ within an organism performs specific tasks to maintain the overall health and function of the organism. To accomplish these tasks, an organ typically requires interaction with other organ systems within the organism.
For example, the digestive system works in tandem with the circulatory system to transport nutrients to the cells, while the respiratory system works with the circulatory system to deliver oxygen to the body. By working together, the different organ systems help to maintain the overall health and function of the organism.
