Before cells divide, they must replicate their entire genome. Explain why
replication of the genome prior to cell division is important.
Each time a cell divides into two daughter cells, its full genome is duplicated; for humans and other complex organisms, this duplication occurs in the nucleus. This minimizes the incidence of errors (mutations) that may greatly affect the resulting organism or its offspring. ...
HOPE THIS HELPED <3
Answer:
In order for all of the cells in your body to maintain a full genome, each cell must replicate its DNA before it divides so that a full genome can be allotted to each of its offspring cells. If DNA replication did not take place fully, or at all, the offspring cells would be missing some or all of the genome.

how to write a narrative story?
Answer:
Start with action or dialogue.
Ask a question or set of questions.
Describe the setting so readers can imagine it.
Give background information that will interest readers.
Introduce yourself to readers in a surprising way.
Explanation:
Answer:
Narrative essays/stories are often anecdotal, experiential, and personal—allowing students to express themselves in a creative and, quite often, moving ways. So, in short, it's an essay about your life with details, events, etc.
Explanation:
Narrative essays/stories should include:
an introduction, plot, characters, setting, climax, and conclusion.must have a purpose; think of this as the thesis of your story.the essay should be written from a clear point of view; essays to be written from the standpoint of the author (you); however, this is not the sole perspective to be considered. Creativity in narrative essays oftentimes manifests itself in the form of authorial perspective. narrative essays are effective when the language is carefully, particularly, and artfully chosen. Use specific language to evoke specific emotions and senses in the reader. the use of the first person pronoun ‘I’ is welcomed; though it is welcomed it is not necessary—nor should it be overused for lack of clearer diction.have a clear introduction that sets the tone for the remainder of the essay. Do not leave the reader guessing about the purpose of your narrative; you are in control of the essay, so guide it where you desire (just make sure your audience can follow your lead).I hope that this helps you! I know it was a lot to read, but it's worth it. Have a nice night! :D
a cell is placed in a isotonic solution. How does the cell maintain homeostasis in the environment ?
Answer:
If a cell is placed in an isotonic solution, there will be no net flow of water into or out of the cell, and the cell's volume will remain stable. If the solute concentration outside the cell is the same as inside the cell, and the solutes cannot cross the membrane, then that solution is isotonic to the cell.

O The eruption caused sunspot activity to increase.
O The volcano released a lot of sulfur dioxide and ash,
O Greenhouse gases caused the cooling of Earth's surface.
Answer: this is easy, i think
Explanation:
The volcano released a lot of sulfur dioxide and ash
According to question, "C" which is the volcano released a lot of sulfur dioxide and ash.
What is a volcano and what causes its eruption?When magma builds up in the magma chamber, it forces its way up to the surface and erupts, often causing volcanic eruptions.
In the ocean, volcanoes erupt along cracks that are opened in the ocean floor by the spreading of two plates called a mid-ocean ridge.
Thus, the volcano released a lot of sulfur dioxide and ash is correct.

Is human blood ever any color other than red?
Answer:
no
Explanation:
Human blood is red because of the protein hemoglobin. Hemoglobin contains a red-coloured compound called heme that’s important for carrying oxygen through your bloodstream
Sometimes blood can look blue through our skin, but its never blue. the reason we see blue is because blue light doesn't go as deep into kin as red. If the blood vessel is deep, your eyes see more blue than red light due to the blood’s absorption of red wavelengths.

A person with a low number of white blood cells could have difficulty in fighting infections and A decrease in the number of lymphoid stem cells could result in a decrease in red blood cell.
What is nucleotide?It is the sub units and buIlding blocks of DNA. It is made up of a five-sided sugar, phosphate group and then a nitrogen base.
These groups make the backbone of the DNA helix. If you look at a DNA helix, they make the side of the ladder or the side portion. They connect to a nitrogen base which make the steps of the ladder. The type of sugar that is used in a DNA helix is called deoxyribose.
Nitrogen bases are the molecules that make up the steps of the ladders. There are four different nitrogen bases, namely; Guanine, Thymine,Adenine and Cytosine.
Pyrimidines are compounds that make a single 6-sided ring. Examples of pyrimidines are Cytosine and Thymine. Purines on the other hand make 5-sided and 6-sided rings.
Therefore, A person with a low number of white blood cells could have difficulty in fighting infections and A decrease in the number of lymphoid stem cells could result in a decrease in red blood cell.

describe one piece of evidence represented by the contour line on the map that indicates the north side of chimney bluffs is steep?
Incomplete question. Attached is the image of the map below.
Explanation:
From the map, we could notice the contour lines around the Chimney Bluff areas are closely packed together. In other words, the spacing between the contour lines is narrower than those found in other locations.
This assertion is accurate because it is a standard practice in many maps to indicate the steepness of an area by having the contour lines in close proximity.
