Name two Earth processes that influence the distribution of natural resources on Earth.
Answer:
Earth's natural resources are unevenly distributed across the globe this can be explained by geological process like the movement of tectonic plates erosion and volcanic activity.
Explanation:
Hope this helped Mark BRAINLEST!!
Answer:
I'm not 100% sure
Explanation:
Different regions have access to different renewable or nonrenewable natural resources such as freshwater, fossil fuels, fertile soil, or timber based on their geographic location and past geologic processes. Access, or the lack thereof, contributes to a place’s economic development, political relationships, and culture. For example, the Great Plains region of the United States is known for its abundance of fertile soil. As a result, its main industry is agriculture. Corn, soybeans, and wheat are globally exported from this region and serve as the main economy. On the other side of the spectrum, the desert southwestern region of the United States depends on the Central Arizona Project canals to transport water from the Colorado River in order to support agriculture and urban areas. Arizona’s right to use water from this river stems from the Colorado Compact, an agreement established in 1922.

Answer: Check picture
In very early attempts to classify organisms, the greek philosopher, Aristotle, identified all animals as "aire dwellers, land dwellers, or water dwellers". Under this system, all of the following organisms would have been placed in the same group: bat, grasshopper, eagle, butterfly, flying squirrel, and sparrow. In the space below, construct a dichotomous key that can be used to identify 6 animals.

What role do genes have in making proteins?
Answer:
A few genes produce other molecules that help the cell assemble proteins.
Explanation:
During the process of transcription, the information stored in a gene's DNA is transferred to a similar molecule called RNA (ribonucleic acid) in the cell nucleus. Both RNA and DNA are made up of a chain of nucleotide bases, but they have slightly different chemical properties. The type of RNA that contains the information for making a protein is called messenger RNA (mRNA) because it carries the information, or message, from the DNA out of the nucleus into the cytoplasm.

How is an analogy different from a simile and a metaphor?
An analogy compares things, while similes and metaphors only describe them.
An analogy compares several different aspects of one thing to another.
An analogy uses like or as to make a direct, simple comparison.
An analogy makes a direct, simple comparison without using the words like or as.
Answer: A simile is saying something is like something else. A metaphor is often poetically saying something is something else. An analogy is saying something is like something else to make some sort of an explanatory point. You can use metaphors and similes when creating an analogy.

Answer:
the diagram shows the body structures that are similar though in different species due to common ancestry, this evidence is comparative anatomy.
Answer:
The diagram shows that they have homologus structure. All of these different species have the same bones but differnt fuctions like swimming vs flying. They show that we call came from a common ancester because we have similar structures even though they are differnt species.
Explanation:
how does the density of water affect the movement of water around the globe?
Answer:
The Role of Density
Explanation:
Denser water tends to sink, while less dense water tends to rise. Cold-water currents occur as the cold water at the poles sinks and slowly moves toward the equator. Warm-water currents travel out from the equator along the surface, flowing toward the poles to replace the sinking cold water.
