Answer:
C- Plant cells make their own food, but human cells do not.
Explanation:
Animal cells must take food in from some other source. Plants, on the other hand, have the ability to make their own food through a process called photosynthesis. In essence, the plant cell uses the energy in sunlight to combine carbon dioxide and water to make molecules of glucose and to release oxygen.
D is wrong because the human body uses three types of molecules to yield the necessary energy to drive ATP synthesis: fats, proteins, and carbohydrates. Mitochondria are the main site for ATP synthesis in mammals, although some ATP is also synthesized in the cytoplasm.
A is wrong because plant cells obtain energy through a process called photosynthesis. Secondly, that energy is used to break down carbon dioxide and form glucose, the main energy molecule in plants. Plants, algae and some bacteria use photosynthesis to create energy used for growth, maintenance and reproduction.B is wrong because food provides building materials for your body. Your body needs building materials so it can grow and repair itself. Specifically, it needs these materials to produce more cells and its components. Food contains substances that help control body processes.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.

Compare the structures for genetics with every day objects. Must include the words: genes, DNA, chromosomes, and nucleus.
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.

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
Answer:Student 2
Explanation:
The conclusion of student 2 is scientifically valid based on the data in the table above. Thus, the correct option for this question is B.
How the pH of the soil is measured?The pH of the soil is measured with the help of a pH meter. The soil from a particular area is mixed with water and other chemicals in order to make a solution, then by utilizing a pH meter, an accurate pH of that region of the soil is measured successfully.
According to the conclusion of 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. This is because the pH of the edge of the parking lot is significantly high as compared to other areas that surround the school.
Therefore, the conclusion of student 2 is scientifically valid based on the data in the table above. Thus, the correct option for this question is B.

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.

B. The arctic fox is a producer while the pine tree is a consumer
C. The pine tree is abiotic while the arctic fox is biotic.
D. The pine tree is not adapted to survive in the cold weather
Please help!
