a. The atom’s volume increases.
b. The atom’s mass increases.
c. The atom becomes positively charged.
d. The atom becomes negatively charged.
c. The atom becomes positively charged
if the electrons are removed it means theres no longer a negative charge to balance the positive charge of the protons in the atom

The Organelles help the cell to function efficiently.
What are the organelles in the cell?I can see that your question has to do with the organelles in the cell but I don't quite get the analogies that you intend to use. However, I would explain the organelles one after the other.
Endoplasmic reticulum: The endoplasmic reticulum (ER) is a network of membranous tubes and sacs within the cytoplasm of eukaryotic cells. It serves as a transport system for proteins and lipids, as well as a site for folding and modification of newly synthesized proteins.
Ribosomes: Ribosomes are complex molecular machines that are found in the cytoplasm of all living cells. They are responsible for synthesizing proteins from amino acids, which are the building blocks of proteins.
Mitochondria: These are organelles found in the cytoplasm of eukaryotic cells. They are often referred to as the "powerhouses" of the cell because they are responsible for producing most of the cell's energy in the form of ATP (adenosine triphosphate).
Vacuole: Vacuoles are membrane-bound organelles found in eukaryotic cells. They are large, fluid-filled compartments that serve several important functions within the cell, including storage of nutrients and waste, regulation of the cell's water balance, and maintenance of cell shape.
Cytoplasm: Cytoplasm is the gel-like substance that fills the interior of eukaryotic cells, excluding the nucleus. It is a complex mixture of water, ions, organic molecules, and a variety of cellular structures, including organelles such as mitochondria, ribosomes, endoplasmic reticulum, and lysosomes.
Lysosomes :Lysosomes are membrane-bound organelles found in eukaryotic cells. They are referred to as the "garbage trucks" of the cell because they are responsible for breaking down and recycling cellular waste and unwanted material.

The water of a swimming pool is hypotonic to our cells. Explain in detail with evidence and reasoning why we do not swell and pop when we go for a swim.
Answer: Hello: ) ✨ It depends on the concentration of all solutes in the solution (ie, its osmolarity). A solution with low osmolarity is hypotonic and vice versa. Solutions having the same osmolarity are isotonic. Water in pools and rivers is hypotonic compared with sea water, but water from the Dead Sea is hypertonic.We do not swell and pop when we go swimming in a hypotonic swimming pool because our skin protects us from the external environment and does not let water cross into or out of our body surfaces. ... hope this helps have a great dayAssuming the water is warm enough that you don’t simply die of hypothermia, the next problem would be your skin. For reasons that still aren’t well understood, human skin starts to break down after continuous immersion in water of a few days. You’d suffer open sores and be liable to fungal and bacterial infections just from the spores on your skin, even if the water itself was perfectly sterile. The pressure of the water also reduces the circulation to your extremities and makes breathing more difficult.
Explanation:
A relative term, hypotonicity defines a solution's characteristic in relation to another solution.
What is hypotonic solution?The cytosolic fluid or the fluid found inside a cell is frequently used as the comparison solution in biology. Therefore, a solution would be considered hypotonic in biology if it contained fewer solutes than the cytosol of a cell. The semipermeable membrane is the cell membrane. What then occurs to a cell in a hypotonic environment.
Tonicity has the prefix "hyper," which denotes "more" or "excess." Consequently, a solution that contains more non-penetrating solutes than the other solution can pass through a semipermeable barrier.
Therefore, A relative term, hypotonicity defines a solution's characteristic in relation to another solution.

In an electrical wire, if instead of copper, plastic wire is used. Would it conduct electricity?Justify your answer.
Answer:
No, a plastic wire would not conduct electricity. This is because plastic is an insulator that does not allow electric current to flow through it. In a wire, electrical conductivity is provided by the movement of charged particles - typically, electrons. Copper is an excellent conductor of electricity because it has a high number of free electrons that are not bound to atoms and can move through the wire very easily. However, in a plastic wire, the tightly bound electrons of its atoms do not allow for the free flow of charges, thus preventing the passage of electric current.
Water is unique in that it exists in all three states on Earth. Which statement best describes what happens to the energy of the particles when water vapor begins to cool?
Question options:
A The average kinetic energy remains the same.
B The average potential energy remains the same.
C The average kinetic energy decreases.
Answer:
I think your answer will probably be c
Explanation:
because : As the molecules lose heat, they lose energy and slow down. They move closer to other gas molecules.
The condensation of water has been resulted in the decreased kinetic energy. Thus, option C is correct.
The kinetic energy has been the energy possessed by the moving particles. The energy of the gaseous particles has been higher while the liquid molecules have consisted of the lower kinetic energy.
The particles of water have been started to condense with the cooling. There has been a change in the phase of the water from the liquid to the solid-state. Since there has been the condensation of the particles, the energy of the particles has been decreased.
Thus, the cooling of water particles has been the representation of decreased kinetic energy. Thus, option C is correct.

What happens to the atoms that make up hydrogen fuel as it burns?
Answer:
When hydrogen fuel burns, its atoms combine with oxygen atoms in the air, which creates a chemical reaction that releases energy in the form of heat and light. The hydrogen atoms lose their outermost electrons, becoming positively charged ions (protons). These ions combine with the oxygen atoms to form water molecules (H2O), which evaporate into the air as steam. Therefore, the atoms that make up hydrogen fuel ultimately become part of water molecules during the process of combustion.

What physical property of mercury makes it best suited for use in a thermometer
Answer:
High coefficient of expansion
Explanation:
It is only mercury that is in liquid form at room temperature. It works on the principle of thermal expansion, it expands when heated and contracts when cooled. The very minute change can be notable by the use of mercury in the thermometer. So this property of the thermometer makes it suitable for measuring temperatures.

The concept Le Chatelier's principle is used here to determine the effect of change of concentration, pressure and temperature on the state of equilibrium.
What is Le Chatelier's principle?According to Le Chatelier's principle, If a system in equilibrium is subjected to a change in concentration, pressure or temperature the equilibrium shifts in the direction that tends to reduce the effect of the change.
Here adding CaO increases the rate of forward reaction. If the concentration of any reacting species is increased, the equilibrium will shift in the forward direction.
The given reaction is exothermic in forward direction. So the increase of temperature shift the equilibrium to the backward direction and the decrease in temperature shift the equilibrium to the forward direction.
Here increasing pressure will shift the equilibrium to the forward direction accompanied by a decrease in the number of moles.

How is density different from weight and mass?
Hello there!
How is density different from weight and mass you say? It's simple!
