How do living and nonliving things differ?
Answer:
Hey mate.....
Explanation:
This is your answer,
Living things differ from non living things through motion, action, expression, way of living and etc......
Livings things:-
1. Livings things means something that keeps on moving or doing any particular work.
2. Livings things mostly consume, remove, and reproduce through different ways.
3. Examples of livings things are humans, animals, birds, reptiles, and even the germs like bacteria, fungi, ameoba and etc....
Non Livings things:-
1. Non Living things means something that just stays like a statue usually and never move or do a particular work.
2. Non living things do not consume, remove or reproduce anything.
3. Examples of non living things are table, chair, fan, house, book etc....
hope it helps you mate....

Energy can be neither created nor destroyed. This fact means that even though energy sources can be depleted (used up), the energy in them is not destroyed. Instead, it is transformed to other forms of energy. And almost all energy resources here on Earth can have their energy traced back to the Sun’s gravitational or light energy.
Electricity is often thought of as a secondary source of energy because it must be gained by transforming some other kind of energy (a primary source). Think about where the electricity generated by a wind turbine comes from. Describe the path that wind energy takes from the Sun’s light to electricity.

Explanation:
Magnesium is a metal with two electrons in its outermost energy level. When it becomes an ion, what happens to its valence electrons? What happens to its charge?
Answer:The answer to your question is Mg loses its valence electrons and acquire a positive charge (Mg⁺²).
Explanation:
Answer:
When it becomes an ion, it donates its valence electrons and becomes positively charged. The positively charged ion would be Mg²⁺ because it loses two electrons. It would have 12 protons and 10 electrons.
Hope that helps.

How are the volvox, euglena, paramecium, and amoeba similar and different in how they move, and eat?
Answer:
Both can hunt for their food (heterotrophs), but euglena can also make their own food (autotroph) with its chloroplasts. Amoeba have pseudopods to move/eat, but euglena have flagella to move. How are euglena and paramecium similar and different? ... Both also use flagella to move, but volvox move together in colonies.

What does the conversation of mass say about the amount of atoms in the reactants compared to the products?
Answer:
the mass of any one element at the beginning of a reaction will equal the mass of that element at the end of the reaction. If we account for all reactants and products in a chemical reaction, the total mass will be the same at any point in time in any closed system.
Answer:
[tex]\boxed {\boxed {\sf Atoms \ in \ reactants \ = atoms \ in \ products}}[/tex]
Explanation:
The Law of Conservation of Mass states that mass cannot be created or destroyed.
In a chemical reaction, this means the mass of the reactants (substances going in and being changed) must equal the mass of the products (new substances from the reaction).
In addition, the amount of atoms must stay the same. The atoms can and will reconfigure to form different compounds, but the number of atoms stays the same.
Which type of variable is kept the same throughout an experiment?
Constant variable
Measured variable
Outcome variable
Test variable
Answer:
Constant variable.
What causes the electrons to move and form static electricity?
moist air
dry air
friction
Answer:
friction
Explanation:
The rubbing of certain materials against one another can transfer negative charges, or electrons.
The friction generating between the surface of two objects causes the electrons to move from one body to the other and form static electricity. Hence, option c is correct.
What is static electricity ?Static electricity is the flow of electrons that occurs due to the temporary polarization of two bodies. When a conducting surface rub on other surface, they gets electrons by frictional force.
These free flow of electrons make them negatively charged. When this negatively charged body comes in contact with a non conducting surface they latter gets polarized by the electrons of negatively charged body.
The positive charges of the nonconducting surface gets attracted to the negative body and the electrons flow from the negatively charged body to the partially polarized positive body. This is called static electricity.

How many protons, neutrons, and electrons does potassium's neutral atom have?
Answer:
The number of neutrons is entirely dependent on the Mass number of the particular atom. The standard mass for potassium is 39.
Potassium is element number 19, so it has 19 protons and 19 electrons in the neutral atom. It has therefore 39-19 = 20 Neutrons.
