Answer:
Mutation
Explanation:
Mutation is any alteration or change in the genetic sequence of a gene caused by mutagens (substances) or mistakes during replication of genetic sequences.
A mutation occurs in the gene from time to time, although, the cell has protocols in place to put them under control if they occur. However, when DNA or a gene is being copied and transferred to offsprings, there is bound for mistakes called MUTATION to occur.

3.4.3 Lab: Why are cells so small?
Answers
Answer: The important point is that the surface area to the volume ratio gets smaller as the cell gets larger. Thus, if the cell grows beyond a certain limit, not enough material will be able to cross the membrane fast enough to accommodate the increased cellular volume. ... That is why cells are so small.
Explanation: because they can absorb nutrients much more efficiently. Because they are smaller they can efficiently absorb enough food. ... When a cell doubles in size the volume increases much more then the surface area, which is why large cells cannot receive enough food efficiently for their volume. Cells are small because they are more efficient as smaller entities. Information within small cells is transmitted more quickly and efficiently than within larger cells. ... Thus a higher cell surface area-to-volume ratio, i.e., smaller cell size, is desired for most efficient cellular activity.
The cells are so small because their small size allows them to take in food and get rid of the waste.
The cells are the basic structural and functional unit of all organisms on earth except the Viruses. The size of the cell is so little it allows the organism to maximize the ration of surface area to volume. Smaller cells are expected to have greater ratio which promotes more molecules as well as ions to move across the plasma membrane.The small size of the cell facilitate to get the nutrients inside the cell and waste outside the cell quickly. Hence, small size of cell facilitates to get food inside and get rid of waste.Learn more about cell:

Answers
Answer:
Mechanical waves react to different mediums in different ways. Some mechanical waves are TRANSMITTED through a medium, meaning they pass through the medium.
The way in which waves are transmitted depends upon the type of material. In SOLIDS, mechanical waves travel rapidly, because the molecules are DENSELY packed. In liquids and air, however, mechanical waves travel more SLOWLY, because the molecules are spread farther apart.
Other mechanical waves are reflected off a medium. When a mechanical wave is reflected, it BOUNCES off the medium and then travels in a DIFFERENT direction. SONAR is an application that uses sound wave reflection to determine how deep water is.
A third way mechanical waves react to a medium is ABSORPTION. When a mechanical wave is absorbed, it remains WITHIN a medium and is not transmitted to another medium.

B. A helicase enzyme unwinds the DNA molecule, then corresponding nucleotides are added to the separated original strand forming two separate semiconservative molecules
Explanation:
DNA Replication is an important phenomenon as far as cell division is concerned. It is the process whereby a DNA molecule doubles its content or forms two DNA molecules from one.
In the semi-conservative model of DNA replication, an enzyme called DNA helicase unwinds the double stranded DNA molecule into two single strands. The single strands are then used as template for DNA polymerase to synthesize another molecule of DNA. Hence, two separate DNA molecules comprising of one old strand and one new strand.

Answers
Answer:
1) Create a hypothisis 2) Create experiment 3) collect data 4) write conclusion
The four steps that a scientist uses to solve a problem are creating hypothesis, experiment, data sorting and writing conclusion.
What are hypothesis?A hypothesis is an elaboration posited for a characteristic. The scientific technique requires that a hypothesis be testable in order for it to be considered a scientific hypothesis.
Scientists typically base scientific hypotheses on previous findings that cannot be adequately explained by existing scientific theories.
Any process that co-ordinate system data into some defined order to make it simpler to understand, analyze, or visualize is referred to as data sorting.
The conclusion is the final section of an academic essay. The conclusion should restate your response to the question and briefly summarize key points. It does not contain any new points or information.
A scientist solves a problem by developing a hypothesis, conducting an experiment, sorting data, and writing a conclusion.
Thus, by using these steps, scientist can come to an end for the problem.
