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.
Should we stop drinking bottled water? why and why not
What are the characteristics of a foliated metamorphic rock?
Answer:

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.

Look at the following diagram of the carbon cycle. An image of carbon cycle is shown. The sun, a cloud, two trees, one on the left and the other on the right, an animal, lake, and a factory are shown in the image. An arrow is shown from the sun towards the left tree marked A. The sun is marked B. There is an arrow from the air above the clouds, marked C, towards the left tree. An arrow from a location close to the ground marked D points towards Dead Organisms, which is a label under the animal. An arrow marked E points from the right tree straight up to the clouds. An arrow marked F points from the animal straight up to the clouds. An arrow marked G points from the factory towards the air above the clouds, C. There is an arrow pointing from the air to the lake labeled Carbonates in Water, an arrow pointing down from dead organisms to Fossils and Fossil Fuels, and an arrow from Fossils to the factory. Which of the following facts is best represented by the arrow pointing from C to A? The energy stored in atmospheric carbon dioxide is conserved because it is used to create new forms of energy present in decomposed plants. The energy stored in atmospheric carbon dioxide is conserved because it is transformed into glucose during photosynthesis. The chemical energy present in carbon dioxide is reduced when it is converted into chemical energy in glucose. The chemical energy present in carbon dioxide is used up completely during the burning of trees.

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.

Explanation:
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.
