<h3>
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.
Answer:
Larger plants become the dominant organisms
The correct answer is high, low.
Arteries are part of the circulatory system and are responsible for carrying blood away from the heart and around the body. The arterial blood is oxygenated and this process ensures that every tissue around the body will receive oxygen and nutrients through this blood flow.
Veins are also part of the circulatory system and are responsible for carrying the deoxygenated blood from the tissues back to the heart.
Venous pressure is much lower than the arterial pressure. More specifically, venous pressure ranges from 5 to 8 mmHg, while arterial pressure ranges from 15 to 30 mmHg.
<span>A. Acquired traits can be passed to offspring
Jean-Baptiste Lamarck first presented his Theory of Inheritance of Acquired Characteristics in 1801. According to his theory, if an organism changes in order to adapt to its environment, the changes are passed on the organism's offspring. Some of his proposed ideas in the theory, however, were dismissed by other scientists by experimenting and studying of genetics.</span>
