What happens to the properties of atoms when they are joined through a
chemical reaction to form a compound?
Answer:
The atom's properties are rearranged.
Explanation:
"A compound is a substance formed when two or more elements are chemically joined. ... When the elements are joined, the atoms lose their individual properties and have different properties from the elements they are composed of. A chemical formula is used a quick way to show the composition of compounds."
"They are rearranged to form new products [in a chemical reaction] with different physical and chemical properties from the reactants."

If the sun is so massive, why does the Earth have a greater pull on the moon than
the sun does?
Answer:
Even though the sun is much more massive and therefore has stronger overall gravity than the moon, the moon is closer to the earth so that its gravitational gradient is stronger than that of the sun
Identify the plant cell organelle in which photosynthesis takes place.
Help pleaseeee!
Answer:
chloroplast
Explanation:
In plants, photosynthesis takes place in chloroplasts, which contain the chlorophyll. Chloroplasts are surrounded by a double membrane and contain a third inner membrane, called the thylakoid membrane, that forms long folds within the organelle.
The plant cell organelle in which photosynthesis takes place is chloroplast. The correct option is D.
Plant cells and some algae contain unique organelles called chloroplasts. They have a green pigment called chlorophyll, which is in charge of absorbing solar light energy.
Chloroplasts utilize this light energy during photosynthesis to create glucose, a molecular energy source, and oxygen from carbon dioxide and water.
Because it enables them to transform light energy into chemical energy, which feeds their development and supplies them with nutrients, plants need this process to survive.
Because of their special adaptation for photosynthesis, chloroplasts are essential to the plant's capacity to produce food.
Thus, the correct option is D.

Viscosity is a measure of a fluid's resistance to
flow
A: True
B: False
Answer:
Viscosity is a measure of a fluid's resistence to flow is true i believe
Viscosity is a measure of fluids' resistance to flow a correct statement. So the correct option is True.
What is viscosity?The measurement of a fluid's resistance to its own flow and any objects that may be inserted in it is called viscosity.
Viscosity is given by the symbol η (eta) and is defined as the ratio of shearing stress (F/A) and the velocity gradient of the flow of a liquid (dvx/ dy).
Velocity is also defined in the form of Newton’s equation which states that the shear force resulting is directly proportional to the applied force and it is inversely proportional to the viscosity.
The SI unit for velocity is Pascal. Second (Pa S).
The other form of viscosity is called kinetic viscosity which is the ratio of a fluid’s viscosity to its density. It is given by ν (nu). It is a measure of the resistance of a liquid against flowing when it is under the influence of gravity. The SI unit of kinetic viscosity is a square meter per second.
Therefore, the above statement is true.

The correct answer is - option C. 2 billion.
Explanation:
Cyanobacteria or BGA are microscopic organisms that live in water bodies normally and make their own food. These are unicellular organisms that have been around 3 and a half million years and consider as the first photosynthetic organisms responsible for the availability of oxygen on earth. These cells are also considered as the cell that evolved in the eukaryotic cells by differentiation around 2 billion years ago. The aggregated form of the cells are known as the mats.

ANSWER ASAP PLEASE. What process occurs after glycolysis if oxygen is still available for cellular respiration?
Glycolysis is the process of breaking glucose into energy. If oxygen is still available for cellular respiration after glycolysis then, the Krebs cycle and oxidative phosphorylation will occur.
What is Kreb's cycle?Kreb's cycle (TCA) is the important cycle in aerobic organisms that produce energy from acetyl CoA into NADH, ATP, and FADH₂ through the proteins, carbohydrates, and fats.
In oxidative phosphorylation, the ATP synthesis is connected to the ETC and along with the citric acid, the cycle produces more energy in the form of ATP in the presence of oxygen.
Therefore, the Kreb cycle and oxidative phosphorylation occur if oxygen is still available after the process of glycolysis.
