Atom is the
most basic unit of matter. They are the general term used to describe pieces of
matter. But a different kind of atom makes up an element. A combination of atom of different elements
creates a molecule. For example, you have water; it has a chemical formula of
H2O. If you separate H from O, you have two atoms. Two atoms for hydrogen and
one atom for oxygen. However, they are of different elements. And when you
combine them to form H2O, you create a molecule. Another example of molecules are air. Air pressure is gravity pulling down on air molecules. Like us,
air has also mass and the pressure is brought down by the earth’s gravity
causing an increase in weight exerted on you as you descend lower into the
atmosphere. So, as you enter into the other layers of atmosphere above the
troposphere, the air pressure starts to decrease. <span>Below the atmosphere is the
hydrosphere. This is where all liquid forms are located. And since the seawater
has a greater mass than air, it has the greatest pressure. </span>
Answer:
Explanation:
c He compared data of planetary motion at different times along orbits.
The answer would be dancing.
Aerobic exercises is also known as cardiovascular exercise. The primary goal of these type of exercises is to get your heart pumping and blood flowing as you do the exercises. Aerobic exercises involves aerobic metabolism which means it is heavily dependent on oxygen. The oxygen stimulates cellular processes to produce energy to enable you to do these exercises.
Answer:
Simple diffusion is when the particles travel through the cell and facilitated diffusion is when the molecules travel through the cell.
Answer:
It determines everything about you.
Explanation:
Sequencing DNA means determining the order of the four chemical building blocks - called "bases" - that make up the DNA molecule. The sequence tells scientists the kind of genetic information that is carried in a particular DNA segment.
