There are three main subatomic particles namely electrons, protons and neutrons. However, the question only discusses two of them; electrons (negatively charged) and protons (positively charged).
A. Found in all matter
Answer: They are <u>both</u> found in all matter since all matter are made up of atoms and all atoms have both protons and electrons (and even neutrons).
B. Negative charge
Answer: The subatomic particle with negative charge (as discovered by R.A Millikan) is the <u>electron</u>
C. Exists in the nucleus
The subatomic particles found in the nucleus are the <u>protons</u> and neutrons.
D. Attract opposite charges
They <u>both</u> (protons and electrons) attract opposite charges because they are of opposite charges and generally unlike charges attract.
E. Moves at extreme speed
Of the two subatomic particles mentioned, <u>electrons</u> move faster than protons because of there lighter mass when compared to the protons. However, the fastest subatomic particle is the neutrino.
F. Bound by strong force
The <u>protons</u> are bound by strong nuclear force which binds them to the nucleus of the atom.
Answer:
X. Mechanisms and habits that include limit water loss.
Explanation:
Many mammals that live in dry ecosystems tend to have above adaptations because there is a shortage of water in these areas. And of course water is the most essential thing for survival.
Answer:
Mechanical energy is one of the only types of energy that is easy to see. If something is moving, it is using mechanical energy! Take a look at these sources of mechanical energy that you're likely to find in the home.
-
Turning a doorknob
-Breathing in and out
-
Hammering a nail
-Riding a bicycle
-Sharpening a pencil
-Using kitchen appliances
-Listening to music
-Typing on a keyboard
-Driving a car
-Exercising
Explanation:
<em>Mechanical- </em>Mechanical energy is the sum of kinetic and potential energy in an object that is used to do work. In other words, it is energy in an object due to its motion or position, or both.
Answer:
cytoplasm
Explanation:
A cell can be thought of as a "factory," with different departments each performing specialized tasks. A cell's plasma membrane regulates what enters or leaves the cell.
