Answer:
We breathe in air which has a higher concentration of oxygen than carbon dioxide and we breathe out air with a higher concentration of carbon dioxide. Both the gases are present in the inhaled and the exhaled air.
Answer:
1000 years
Explanation:
The timeline provided shows the major vents in the history of Ancient Egypt. We can see that Upper and Lower Egypt have unified in 3100 B.C. The ruler who unified the lower and upper Egypt was Menes, who also started the First Dynasty of Egypt.
By the timeline, Middle Kingdom started in 2100 B.C<u>.</u> This period is started with the reunification of Egypt after the Old Kingdom and the age during which Egypt wasn’t as powerful. Mentuhotep II is the one who reunited Egypt and the first pharaoh of the Middle Kingdom.
<u>We can therefore conclude that the Middle Kingdom started 1000 years after the first unification of Egypt.</u>
Answer: <u>Sensation , Perception
</u>
Explanation:
Sensation is defined as sensing ability persisted by a person through touching, seeing,hearing,smelling or tasting.Sensed information is transmitted to brain in raw form to give it certain definition through recongnization.
Perception is the ability of recognizing and defined the sensed information.Information is perceived to give it a sense.
According to the question,activation of retina receptors for seeing is the sensation occurring in eyes.Anna's ability to interpret and perceive these sensation for recognization of words while reading is perception.
The correct answer to this open question is the following.
Although the question does not provide options or the statements, we can say that statement expresses an assumption behind the articles of confederation that is not behind the US constitution could be the following: "the main principle of the Articles of Confederation was the
the sovereignty of organized power and the independence of the separate or disunited States."
Then, President Adams continued saying that according to the US Constitution, the role of the central government was to serve the citizens of the United States and that each state had to resolve their own administrative issues.
Let's remember that the Articles of Confederation was the first US Constitution, but left a weak central government that depended so much on the states. That is why delegates met at the Constitutional Convention of Philadelphia in 1787, to sign the United States Constitution.
Force: The energy exerted on an object
Force is equal to mass times acceleration, meaning the mass of an object impacts how much force you will apply to it.
Force is equal to mass times acceleration. This means that the amount of force you apply will depend on the acceleration. If one object has a greater acceleration than another, that means you will have to apply more force to the object with a greater acceleration.
The formula that describes the relationship between force, mass, and acceleration is newtons second law. Force is equal to mass times acceleration.
Newtons second law states that the amount of force needed to stop an object is directly related to the amount of mass an object has and the amount of acceleration an object has
