<h3>
Answer: D) all of the above</h3>
Explanation:
The lungs pump oxygen in and carbon dioxide out, which goes through the blood stream to help with the cell's energy needs.
Nutrients pass through the blood stream as well. The nutrients start with the digestive system (mouth, esophagus, stomach, small intestine) before going into the blood stream. The nutrients are building blocks to help make new cells when old ones die off.
When those cells die off, the body sheds them like dead skin, but internal dead cells are passed off as waste. This waste and other byproducts the body doesn't need passes through the blood stream as well.
In short, the blood stream is basically the highway to help get desired materials (eg: oxygen and nutrients) and get rid of waste (eg: carbon dioxide and other unwanted byproducts or dead cell material)
So that's why the answer includes A, B and C.
<span>They both have charged particles
They have the same attractive forces between particles
They have the same space between particles
They create magnetic and electric fields</span>
<span>Identical particles were produced no matter which metal he used.</span>
Answer:
6.1 ×10^-19 J
Explanation:
From E= hc/λ
h= planks constant = 6.6×10^-34 Js
c= speed of light = 3×10^8 ms^1
λ= wavelength = 325 nm
E= 6.6 × 10^-34 × 3×10^8/325 × 10^-9
E= 0.061 × 10^ -17 J
E= 6.1 ×10^-19 J
The words that complete these descriptions are law, hypothesis, and experiment.
<h3>What is a law?</h3>
In science, a law is a statement that accurately describes the way a natural phenomenon occurs. Due to this, laws are created after testing a hypothesis several times. This matches Jean-Baptiste's proposal because his idea about heat flow has been tested by himself and others multiple times.
<h3>What is a hypothesis?</h3>
Different from a law, a hypothesis only states a possible explanation but this should be tested to become a law. This concept can be applied to Sadi because he only has an idea about heat flow but this has not been tested.
<h3>What is an experiment?</h3>
This is a procedure that aims at testing a hypothesis. This concept applies to James because he is carrying out an objective procedure to understand energy and heat.
