A science class breaks into four groups and tests the pH of the soil surrounding the school. Each group goes to an area that is three meters squared (3m 2) in size and tests the soil four different times within that square. The data collected is then placed into a table for everyone to see as shown below.




Four students draw the following conclusions from the data:
Student 1: Group D’s data should be discarded because it is not similar enough to the other groups' data.
Student 2: There must be something near the parking lot that causes the pH of the soil to be higher and the class should design a new experiment to determine what it may be.
Student 3: There are definitely more magnesium ions in the soil near the parking lot, and that is why the pH of the soil is higher there.
Student 4: The pH of the soil in the ball field should be measured again because no two readings were identical.


Which student’s conclusion is scientifically valid based on the data in the table above?


A. Student 1


B. Student 2


C. Student 3


D. Student 4

The Mediterranean Sea was controlled by the Roman Empire which was not given in the options.

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 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.

Answer:

Melting icebergs will cause the sea level to rise. Icebergs are already floating in the ocean, so melting will not raise the sea level. Melting of land-based ice (such as glaciers) will raise sea level.

Explanation:

Option (B) the human eye is only sensitive to a portion of the electromagnetic spectrum (visible lights)  best supports above statement.

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:

Lucille's cells need oxygen. In order for cells to properly function, they need to be oxidized. If Lucille's respiratory system is not working then her body cannot receive the oxygen that it needs in order to send to her blood cells. The circulatory system pumps Lucilles's blood around her body but if there is no oxygen, Lucille's cells/heart cannot properly function, this making it difficult for her to play soccer.

Answer:

Genes play an important role in determining physical traits — how we look —and lots of other stuff about us. They carry information that makes you who you are and what you look like: curly or straight hair, long or short legs, even how you might smile or laugh. Many of these things are passed from one generation to the next in a family by genes. Most cells have one nucleus. The nucleus is a small egg-shaped structure inside the cell which acts like the brain of the cell. It tells every part of the cell what to do. It contains our chromosomes and genes. Chromosomes come in matching sets of pairs and there are hundreds (sometimes thousands) of genes in just one chromosome. The chromosomes and genes are made of DNA.

Answer:

Geological “fit” evidence is the matching of large-scale geological features on different continents. It has been noted that the coastlines of South America and West Africa seem to match up, however more particularly the terrains of separate continents conform as well. Examples include: the Appalachian Mountains of eastern North America linked with the Scottish Highlands, the familiar rock strata of the Karroo system of South Africa matched correctly with the Santa Catarina system in Brazil, and the Brazil and Ghana mountain ranges agreeing over the Atlantic Ocean.

Another important piece of evidence in the Continental Drift theory is the fossil relevance. There are various examples of fossils found on separate continents and in no other regions. This indicates that these continents had to be once joined together because the extensive oceans between these land masses act as a type of barrier for fossil transfer. Four fossil examples include: the Mesosaurus, Cynognathus, Lystrosaurus, and Glossopteris.

Answer:

- Animals live in the trees

- Animals eat off of tree

-Animals breed in trees

Explanation:

Answer:

1. They have less territory

2. With less space, populations decline.

3. Some animals need trees to survive.

Explanation:

1. Some animals, like wolves, have huge territories that span over miles of land. Deforestation would cause predators to fight over who gets the remaining space.

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.

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.

B. Interaction with other organ systems.

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.
