According to theory, the fossils found in the lower layer of rocks are older than those found at a higher layer. Hence, option C is correct.
What are fossils?Any surviving remains, impression, or evidence of a once-living thing from a previous geological epoch is referred to as a fossil. The majority of fossils are created when a living thing (such as an animal or plant) dies and is swiftly buried by sediment (such as mud, sand, or volcanic ash).
Shells, bones, animal or microbe imprints in stone, exoskeletons, items preserved in amber, petrified wood, coal, hair, oil, and DNA traces are a few examples of fossils.
As fossils get older, they get buried more down in the soil, older fossils are found in the lower layer, while younger fossils are found in the upper layer. Therefore, option C is correct.

Which statement best explains the importance of enzymes lowering the activation energy necessary for reactions to take place?
a Reactions that require less energy to begin are able to occur more quickly.
b Reactions produce heat, causing the chemical bonds to become strong.
c Reactions are able to proceed slowly to maintain the metabolism of the cells.
d Reactions requiring less energy are able to produce less product.
Answer:
A
Explanation:
because a enzyme simply speeds up a reaction and only does that by pressure and stress not by doing chemical changes
The statement which best explains the importance of enzymes lowering the activation energy necessary for chemical reactions to take place is: A. Reactions that require less energy to begin are able to occur more quickly.
A chemical reaction can be defined as a chemical process which mainly involves the continuous transformation or rearrangement of the ionic, atomic or molecular structure of a chemical element through a break down and formation of chemical bonds, in order to produce a new chemical compound.
As a general rule, the activation energy of a chemical reaction must first of all be reached by its combining chemical elements (reactants) before it can start or begin.
An enzyme can be defined as a biological catalyst that is used to speed up (increase) or catalyze (accelerate) the rate of a chemical reaction, by lowering (decreasing) the activation energy of its constituent chemical elements (reactants).
Hence, a chemical reaction that only require less energy to begin (start) are able to occur more quickly before those that require high energy.
In conclusion, the activation energy of a chemical reaction should be lowered in order for it to occur or take place fast (quickly) enough over a short period of time.

In the diagram below, C is the midpoint of AB. If AC is 8 centimeters, what is the length of CB?
A. 8 cm
B. 6 cm
C. 16 cm
D. 4 cm
Answer: 8cm
Explanation:
Since C is the midpoint of AB, it means that AC and CB are equal in length. So, if AC is 8 centimeters, then CB is also 8 centimeters.
What is a midpoint ?In geometry, a midpoint is the point that divides a line segment into two equal parts. In this diagram, C is the midpoint of the line segment AB, which means that the line segment AC is equal in length to the line segment CB.
We are given that AC is 8 centimeters in length. Since CB is also equal in length to AC, we can conclude that CB is also 8 centimeters in length. Therefore, the correct answer is A: 8 cm.
To summarize, when a line segment is divided into two equal parts at the midpoint, the two resulting line segments are also equal in length.
In this problem, we use this fact to determine that CB is also 8 cm in length since it is the other half of the line segment that is 8 cm long.

The Devils Hole pupfish is one of the world's rarest fishes, spending most of its life in the top few meters of very warm waters of a cavern located in the middle of the Mojave Desert. Devils Hole,
a geologic pool, is the only naturally occurring habitat for the endangered Devils Hole pupfish. This fish's habitat is one of the smallest natural ranges known for any vertebrate. Devils Hole is an
extreme environment, with water temperatures and dissolved oxygen concentrations near the lethal limits for most fish species.
Which of the following statements best explains why the Devils Hole pupfish are able to live in this environment?
Answer:
Thermal invasive
Explanation:
Devils Hole pupfish can live in this environment because they have adapted genes, which offer resistance to their bodies to the harsh environment where they live.
We can come to this answer because:
A living being can only live in an inhospitable environment if its organism allows for an adaptation.In this case, we can say that Devils Hole pupfish had a population with different genetic compositions, where some had genes adapted to this environment and others did not have these genes.Devils Hole pupfish that didn't have the adapted genes didn't resist the environment and died.The Devils Hole pupfish that possessed the genes survived and passed those genes on to their descendants.In this case, Devils Hole pupfish that received the genes adapted to the environment developed resistance that allows them to live amidst extreme resources.
