Explanation:
Every compound can be represented by a chemical formula. A chemical formula is the set of symbols showing the elements that make up a compound and their proportions. Water’s chemical formula is H_2 2 O. That means a molecule of water contains two atoms of hydrogen and one atom of oxygen chemically bonded. A molecule is a group of two or more atoms bonded together. Molecules can range in size from two to thousands of atoms. A molecule of a compound is the smallest unit of that compound. Every molecule of water has all the physical and chemical properties of water. That’s because every molecule of water is made of the same elements in the same proportions: two hydrogen atoms and one oxygen! Which of the following is a true statement?
A
Every molecule of the same compound will have different properties.
B
Every molecule of a compound has the same proportion of elements.
C
Molecules can be physically separated into smaller units of a compound.
D
Molecules cannot be represented by chemical formulae.
Answer: The answer is b!
Explanation:
B. Every molecule of a compound has the same proportion of elements.
What is a chemical compound?A chemical compound is a substance made up of two or more different elements that are chemically bonded together. The elements in a chemical compound are present in a specific ratio, and the properties of the compound are determined by the properties of its constituent elements and their arrangement.
Examples of chemical compounds include water (H2O), table salt (NaCl), and carbon dioxide (CO2). The chemical formula of a compound represents the types and number of atoms present in a single molecule of the compound. In the case of water, the chemical formula is H2O, indicating that it is made up of two hydrogen atoms and one oxygen atom.

In your own words, describe why an astronaut's weight is different on the moon than it is on Earth.
An astronaut's weight is different on the moon than on the earth because of the weak force of gravitation on the moon.
What is weight?Weight is the gravitational pull of a second, much larger object, like the Earth or Moon, on a first object. The universal law of gravity states that any two things will attract each other due to their masses with a force directly related to the product of their masses and inversely related to the square of the distance between them. This law is the cause of weight.
As a result, larger objects naturally weigh more when placed in the same spot; yet, the weight of an object decreases the further it is from the Earth. Due to the Earth's polar radius being a tiny bit smaller than its equatorial radius, an object's weight at the South Pole is somewhat higher than its weight at the Equator.
Even if an object's mass is constant, its weight changes depending on where it is. The identical thing weighs one-sixth as much on the surface of the Moon as it does on Earth because of the Moon's lesser mass and radius as compared to the Earth.
Therefore, the weight of the astronaut on the moon will be less than their weight on the earth.

You are looking out over the ocean and see this:
What can you know about the tide?
When we are looking out over the ocean and see this: We can know about the tide that it must be neap tides. Thus, the correct option is A.
What are neap tides?A neap tide occurs seven days after a spring tide. It refers to a period of moderate tides when the sun and the moon are at right angles to each other in space. A spring tide is a common historical term which has nothing to do with that of the season of spring.
A tide just after the first or third quarters of the Moon when there is least difference between the high and low tides is called as Neap tide. During this time, the Moon and the Sun are at right angles to that of the earth. As a result of this, the high tides are not too high, and the low tides are not too low.
Therefore, the correct option is A.

As a body cell grows, the ratio of _______ to volume _________. Before it grows to large, a cell will divide into two ________ cells. So that each new cell receives its own genetic instructions, the cell ________ or copies, all of its DNA.
Answer: As a body cell grows, the ratio of SURFACE AREA to volume INCREASES. Before it grows to large, a cell will divide into two DAUGHTER cells. So that each new cell receives its own genetic instructions, the cell REPLICATES or copies, all of its DNA.
Explanation:
As a body cell grows, the ratio of surface area to volume decreases. Before it grows to large, a cell will divide into two daughter cells. So that each new cell receives its own genetic instructions, the cell replicates or copies, all of its DNA.
The volume of a growing cell increases at a larger pace than the surface area. Hence the ratio of the surface area to the volume of the cell keeps decreasing. At a certain point, the signal to divide is given and this leads to the division of the cell into two daughter cells.
Just before the division, the genetic material of the cell is replicated and other important biomolecules are synthesized before the final call can be made.

C. Fossil Film
D. Trace Fossil
The answer is C, Fossil Film.
The fossil forms through carbonization is fossil fim.
What do you mean by carbonization?Carbonization is the destructive distillation of organic materials, such as dead plants and animals, to produce carbon.
When a fuel is heated without the presence of air, the result is solid, porous carbon. Commercially, coke is made by carbonizing coal at either high or low temperatures.
The process of heating complex carbonaceous materials like wood or agricultural waste to release their elemental carbon and potentially carbon-containing chemical compounds is known as carbonisation.

A scientist observes two stars in the night sky through a telescope. Star A is white in color and relatively dim. The star’s estimated temperature is very high.
Star B is red in color and extremely bright. The star’s temperature is low compared with other stars.
Help the scientist classify the two stars.
Answer:
Star A is a Neutron Star while Star B is a Red Giant
Explanation: Neutron star is a very hot star, very small in size and hence dim and is white in color. A neutron star results after a massive star goes supernova. It is primarily composed of neutrons packed in a small boundary.
star B would be a red giant. This is because, a red giant star is red in color, is very big in size, and has a low temperature. A red giant star is a towards the end stage of a small to an average mass star.

Elements and compounds are pure substances that cannot be broken down physically into a simpler substance. A physical change doesn’t break the bonds between atoms of a substance or form new ones. Compounds can be broken down by a chemical change. A chemical change breaks chemical bonds and/or forms new ones between atoms of a substance. What simple substance would a compound break into? The basic elements that make it up! For example, if you passed a very strong electric current through water you’d break the chemical bonds in water and be left with oxygen and hydrogen. Which of the following is an example of a chemical change?
