One year. It takes 365 days for Earth to orbit the sun.
Gaseous exchange is fundamental in aerobic organisms because oxygen is required to carry out cellular respiration.
<h3>What is cellular respiration?</h3>
Cellular respiration is a series of chemical reactions by which aerobic organisms interchange oxygen and carbon dioxide with their surrounding environment.
During cellular respiration, oxygen is consumed to generate ATP and carbon dioxide is released.
In conclusion, gaseous exchange is fundamental in aerobic organisms because oxygen is required to carry out cellular respiration.

A good conclusion in a research paper restates the hypothesis so that reader can see the value of argument which either defends or criticizes the hypothesis. If it's a long paper it's a good idea to restate the hypothesis in the conclusion. This reminds the user of the hypothesis and draws the paper together. It also revisits the hypothesis and can provide new insight into the hypothesis. Another reason for restating the hypothesis in the conclusion is to pose questions and open the door for future research.
It's purpose is to break down energy from carbohydrates and other organic molecules stored during photosynthesis

Answer: C. a balance and a beaker</h3>
Explanation:
A balance would be used to measure the weight, which in turn effectively measures the mass (more or less). Imagine that we have a brick that we know is 1 pound. If we have an object that needs 5 bricks on one side to balance it out, then we know the object is 5 pounds.
The beaker is used to measure the volume. It's basically a measuring cup that you would find in the kitchen.
To get the density, you divide the mass over volume.
For example, if you have a material that has a mass of 100 grams and it's volume is 20 cm^3, then its density is 100/20 = 5 grams per cm^3.
