a. Mutations are not necessary for evolution because they are not herita
b. Mutations are useful for evolution to occur because they promote ger
uniformity within a population.
c. Mutations are essential for evolution to occur because they produce
variations within a population.
d. Mutations are essential for evolution to occur because they are respo
environmental changes.
Answer: option C.
Mutations are essential for evolution to occur because they produce variations within a population.
Explanation:
This is because Mutation refer to change in the genetic content or DNA composition of organisms. Therefore , for evolution to occur there must be Mutation because it is the main source of genetic variation or causes genetic variation needed for evolution.
Mutation is important as the basics of evolution because it produce a new DNA sequence for a gene function, which lead to the formation of new allele.

Where does the mRNA go after it is produced?
Answer:
The mRNA goes after it is produced is made messenger RNA (mRNA) is a single-stranded RNA molecule that is complementary to one of the DNA strands of a gene. The mRNA is an RNA version of the gene that leaves the cell nucleus and moves to the cytoplasm where proteins are made.
Explanation:
mRNA formed in the nucleus is transported out of the nucleus and into the cytoplasm where it attaches to the ribosomes. Proteins are assembled on the ribosomes using the mRNA nucleotide sequence as a guide. Thus mRNA carries a “message” from the nucleus to the cytoplasm.

Which is the preserved evidence of the activity of an organism a) cast b) mold c) fossil film d) trace fossil
Answer:
fossil film
Explanation:
A carbonaceous film or carbon film is an organism outline of a fossil. It is a type of fossil found in any rock when organic material is compressed, leaving only a carbon residue or film. ... Fossils usually form when sediment buries a dead organism.
The preserved evidence of the activity of an organism is trace fossil. The correct option is d.
What is trace fossil?Animal behavior is what creates a trace fossil. A trace fossil might be something like a dinosaur footprint or an arthropod burrow. Beetles' pre-fossilization burrows can be seen as holes in this petrified wood.
When an organism leaves an impression in mud or sand, a trace fossil is created. Sediment dries out and becomes harder.
A fresh sediment layer has been added on top of it. The remnant fossilizes as the sediment hardens into rock as a result of cementation and compaction.
Body fossils are the hard parts of an individual creature or plant that have been preserved over time. Trace fossils are the best-preserved examples of an organism's past activity.
Thus, the correct option is d.

A cell that is placed in distilled (plain) water will swell up because it fills
with water. Which process causes the cell to swell?
Answer:
If a cell is placed in a hypotonic solution, water will move into the cell. This causes the cell to swell, and it may even burst. A hypertonic solution means the environment outside of the cell has more dissolved material than inside of the cell. If a cell is placed in a hypertonic solution, water will leave the cell.

Which geological feature can be created by a divergent boundary?
A) mid-ocean ridge, rift valley
B) mountain chains
C) earthquakes
D) volcanos
Answer:
A. Mid ocean ridge
Explanation:
A divergent plate boundary often forms a mountain chain known as a ridge. This feature forms as magma escapes into the space between the spreading tectonic plates.
The mid-ocean ridge, rift valley is a geological feature can be created by a divergent boundary. Therefore option A is correct.
A divergent boundary is a type of tectonic plate boundary where two lithospheric plates move away from each other. This movement creates a gap or space between the plates, allowing magma from the asthenosphere (the partially molten layer of the Earth's mantle) to rise and fill the void.
As the magma reaches the surface, it cools and solidifies, forming new crust. This process occurs primarily in the oceanic lithosphere, resulting in the formation of mid-ocean ridges.
Mid-ocean ridges are underwater mountain ranges that run along the seafloor and span across the Earth's oceans.

Define the verb "adapt". Does survival in a particular environment through coping is synonymous with evolution? Why or why not?
Answer:
The word adapt means to get adjusted to a change.
yes, survival in a certain environment is similar to evolution. Both must use adaptation in order for life to keep living through changes in the environment. Each help life sustain itself in a very unique way.

In the process of glycolysis, four ATP molecules are synthesized from four ADP molecules. Why does glycolysis not yield four molecules of ATP?
A TWO ATP molecules are lost in the cytoplasm.
B. Two ATP molecules are converted immediately back to ADP.
C. Two ATP molecules are required to start the process.
D. Two ATP molecules are absorbed in the mitochondria
Answer:
c
Explanation:
two ATP molecules are required to start the process. initially when glucose is phosphorylated it requires energy which is provided by the hydrolysis of ATP so 2 molecules are used up.
Glycolysis does not yield four molecules of ATP because two ATP molecules are required to start the process. Hence option C is correct.
What is ATP?ATP stands for adenosine triphosphate. It is defined as an organic substance that fuels a variety of functions in living cells, including chemical synthesis, condensate dissolution, nerve impulse transmission, and muscular contraction. When the cell needs energy, ATP can be taken out and used to fuel processes or stored for use in later ones.
Glycolysis is defined as the pyruvic or lactic acid is produced as a result of the enzymatic breakdown of a carbohydrate using phosphate derivatives, and energy is stored in ATP's high-energy phosphate bonds. A linear metabolic process called glycolysis uses enzymes to catalyze reactions that break down glucose into two molecules of pyruvate or lactate depending on whether oxygen is present.
Thus, Glycolysis does not yield four molecules of ATP because two ATP molecules are required to start the process. Hence option C is correct.

A.The boiling point is higher for 100 liters of water than for 10 liters.
B.During deposition, a gas changes directly into a solid.
C.The condensation points for oxygen and hydrogen are the same.
D.All of the above.
Answer:
B. During deposition, a gas changes directly into a solid
Explanation:
First we can cross of A, because the boiling point is the same it just takes longer to get there.
So since A. is incorrect, that means D. has to be incorrect too. That leaves us with B. and C.
Finally, I already know what deposition is so since it is not D. it has to be B.

Humans often like to help wild animals. A marine biologist near the area where Anchor’s offspring are located has decided to feed them. He begins putting medicine in the food that keeps the pups from contracting infections common to sharks in the area. Because of this, nearly all of Anchor’s offspring survive to adulthood. Eventually, the marine biologist gets a job transfer and leaves the area. Predict what we may see in the following generation (Anchor’s grandpops). Will they still be fitter than other sharks?
Answer:
I would predict that the the following generation will have a large amount of pups that are eaten by the sharks.
This question seems like its asking about natural selection.
"Natural selection is the process when organisms better adapted to their environment tend to survive and produce more offspring"
Explanation:
If the marine biologist did not give the pups medicine in the first generation, the pups that were less fit or not adaptive to the enviroment to naturally survive the infections would have died. This would have prevented these pups from passing on their genes.
The next generation would consists of pups that are more immune to the sickness or more fit for their enviroment and might experiece less pups to die.
