So the moon does rotate. Why, then, do we see only one face of the moon? One side of the moon always faces Earth because of what's called synchronous rotation. That is, the moon rotates, or spins on its axis, in the same length of time it takes to orbit Earth.

The mass of Betelgeuse is about ___ times the mass of Vega
(This is not multiple choice.)
Answers
Therefore, the mass of Betelgeuse is about 17.634 kg/ 9.5 times the mass of Vega.
Vega is a main-sequence star located in the constellation Lyra. Betelgeuse is a red supergiant star located in the constellation Orion. The mass of Betelgeuse is observed to be about 20 times the mass of the Sun, while the mass of Vega is estimated to be about 2.1 times the mass of the Sun. Therefore, the mass of Betelgeuse is theoretically estimated to be around 9.5 times the mass of Vega.
Experimentally,
The mass of Betelgeuse is 2.188 x10^31 kg
The mass of Vega is 4.246 x 10^30 kg
Hence, the mass of Betelgeuse is about 17.634 kg/ 9.5 times the mass of Vega.

To determine if an object has changed position, you need to know its position relative to another object. ______________
Answers
Explanation: If it’s a true or false it’s true
The statement about the change in position of the object is "true".
What is the position of the object?The exact position or location of an object is specified by its basic dimensions or other means, as well as the distance between the object and the reference point. We need to supply a reference point called the origin to define the position of a material.
When an object moves in relation to a reference point, it is said to be in motion. The reference point that is picked determines how an object moves.
A reference point is a location of the object that is used to determine whether or not something is moving. When an object moves in relation to a reference point, it is said to be in motion.
To determine if an object has moved, you must first know its relative position to a stationary object or reference point.

Answers
Matter are anything that is made up of atoms. The quantity of matter can be observed only on the basis of mass and volume calculation. Therefore, the correct option is option A.
What is matter?Matter is a substance that has some mass and can occupy some volume. The matter is mainly used in science. Matter can be solid, liquid or gas.
Matter is anything that is made up of atoms. Anything around us that can be physically seen and touched are matter. Ice, water and water vapors are example of matter.
So as we saw that matter has some mass so mass can be measured in gram only. Mass can also be represented as number of molecules. We also saw that matter occupy some volume and that volume is measured only in liter. Oxygen is the only thing for which humans depend on marine plants. Oxygen is very important for humans.
Therefore, the correct option is option A.

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.

1156 g/L
= ________ kg/mL
Answers
The Answer is 0.001156.
1156 g/L = 1.156 kg/L
Since 1 L is equal to 1000 mL, we can convert kg/L to kg/mL by dividing by 1000:
1.156 kg/L = 1.156/1000 kg/mL
1.156/1000 kg/mL = 0.001156 kg/mL
Therefore, 1156 g/L is equal to 0.001156 kg/mL.
