The current knowledge concerning cells is the result of the investigations and observations of many scientists. The work of these scientists forms a well-accepted body of knowledge about cells. This body of knowledge is an example of a
(a) hypothesis
(b) controlled experiment
(c) theory
(d) research plan
Answer:
theory
Explanation:
In the scientific method, every scientific investigation begins with observation. After observing the phenomenon, the researcher puts out an intelligent guess that explains his/her observation. This intelligent guess is known as a hypothesis.
This hypothesis is now subjected to carefully designed experiments which may prove or disprove the hypothesis. If the results of the study is well received among the scientific community, the hypothesis becomes a theory.
Hence, a well-accepted body of knowledge about any subject of study in science is an example of a theory.

give at least five insights that you learn from this lesson, as your way of recognizing the uniqueness of earth as a planet life
Answer and Explanation:
The lesson about the uniqueness of the earth allowed me to realize that the earth is the only planet that has drinking water and oxygen, thus allowing the existence of life on the planet and showing that we would not fully survive on another planet.
The lesson also shows that the earth is the only planet where rotation is capable of causing seasonal differences in different parts of the globe. This is important for several things, including food production and plant growth.
Another factor that shows the uniqueness of the land is its favorable temperature for life, allowing us to have water and to be able to live outdoors, for example. This factor is worrying, since the holes in the ozone layer have caused changes in this temperature.
I was also able to learn about the gravity of the earth, which is the only thing that allows us to do all the activities we do and allows us not to be launched into space. In addition, gravity has a strong influence on seas and agriculture.
Finally, I was able to learn about the tectonic plates, which provide the movement of our crust and influence in several geological processes.

How many electrons will a neon (Ne) atom have when it has no charge?
Answer:
hope it helps you
Explanation:
Once one shell is full, the next electron that is added has to move to the next shell. So... for the element of NEON, you already know that the atomic number tells you the number of electrons. That means there are 10 electrons in a neon atom.
The number of protons in one atom of an element determines the atom’s?
The number of protons in one atom of an element determines the atom's identity, and the number of electrons determines its electrical charge. The atomic number tells you the number of protons in one atom of an element. It also tells you the number of electrons in a neutral atom of that element.
The number of protons in one atom of an element determines the atom’s atomic number.
What is atomic number?The atomic number is the number of protons present basically in an atom's nucleus. The number of protons characterize the individuality of an element i.e., an element with 6 protons is a carbon atom, no matter however many neutrons may be prevalent.
The mass number of an element is determined by the number of protons and neutrons combined: mass number = protons + neutrons.
To determine the number of neutrons in an atom, subtract the number of protons, or atomic number, from the mass number.
The atomic number is the number of protons in a nucleus that always equals the number of electrons in orbit around that nucleus (in a nonionized atom).
Thus, it can be concluded that the atomic number is determined by the number of protons in atom.

What words come to mind when you hear the word Philosophy?
Answer:
The words I think of when I hear philosophies are knowledge and reasoning.
Explanation:
So, if you have seen other responses, you would see "love of wisdom." But, there is more to it. When someone says the philosophy usually, someone would think of knowledge or reasoning. When you reason, you reflect, learn, and form opinions using methods of philosophy. So when doing this, you can reason with someone. You could also have "reasoning" with an object or when having a conversation.
You can have an emphasis and an impact when knowing, supported with reasoning. Even though the definition of wisdom, the quality of having expertise, "knowledge" and good judgment; the quality of being wise, wisdom arises from wise-dom, and which is a synonym to philosophy. When your wise and have "knowledge" you, "know something."
When you think of philosophy, the study of the intellectual foundation of a department of knowledge or expertise, you assume that it's wise, or wise-dom, but no. Love of wisdom originates from, "The feeling of love in being wise." As a result, you could tell that philosophy is the love of being wise. Being wise has a reasoning behind it. There is a reason to be wise. People want to be smart and be intelligent for a reason. You want to be a unique person and want to have a justification in a section of experience.
When thinking of it, it's like you are studying knowledge. You are not practicing wisdom. You can't practice being a wise person. It comes with being a Christian or being in that culture, or whatsoever. But you can study knowledge. Each mindset comes with being or "knowing" something. When thinking about each decision, you have to have reasoning behind it.
So, when you consider philosophy, think of "the" philosophy, the roots of it. You have to have a reason to back it up, with reasoning and details. You become a person who displays knowledge. You do not show wisdom through a philosophy. With being wise, you only know certain things. With the information, you know it all. With reasons you don't just have back up you have everything.

Suppose Highlinium-308 can also undergo positron emission
to produce the new element Burienium. What is Burienium's atomic number?
Answer:
The atomic number of burienium will be 307.
Explanation:
During positron emission proton is converted into the neutron and one electron neutrino with positron is released. It means the atomic number will be reduce by one and atomic mass remain same.
For example:
²³Mg₁₂ → ₁₁Na²³+ e⁺+ Ve
Similarly, when highlinium-308 undergoes positron emission the new element burienium is produced and the atomic number will be 307 while atomic mass remain same.
Properties of beta radiations:
Beta radiations are result from the beta decay in which electron is ejected. The neutron inside of the nucleus converted into the proton an thus emit the electron which is called β particle.
The mass of beta particle is smaller than the alpha particles.
They can travel in air in few meter distance.
These radiations can penetrate into the human skin.
The sheet of aluminium is used to block the beta radiation

When a police officer is trying to decide if a driver is speeding, what is his point of reference?a. The ground b. His car c. The speed limit d. All of the above
Answer:
C. The speed limit.
Explanation:
If the car was the point of reference then he would be looking at his car not the speed the car is going. If the ground was the reference then he would be looking at the ground and not how fast the car is going. So that means that the officer is determining how fast the car is going compared to the speed limit.

What if you broke off a piece of cement (or bread) so that it was only half the volume of the original piece? What would happen to
the mass?
Answer:
The mass is also half of the mass of the original piece
Explanation:
Recall that the volume of a substance is defined as mass/volume. The density of substances is a constant. Hence, if a break off a piece of cement or bread such that what remains is only half the volume of the original piece, the mass of the new piece must also reduce to half of the mass of the original piece so that the volume of the material will remain constant.
Hence the answer above.
