Answer:
S-Phase
Explanation:
During the S-Phase, the cell replicates its DNA. Interphase is then followed by Mitosis. Mitosis is when the cell separates its two sets of DNA and divides it into two more cells.

The earth , the sun , and the seven other planets that are in orbit around the sun are part of the solar system. How does the size of the solar system compare with the size of the milky way galaxy ?
Answer:
Size of milky way galaxy is very large than our solar system.
Explanation:
The size of the solar system is much smaller than the size of the milky way galaxy because our solar system is a part of milky way galaxy. The radius of our solar system is 4.545 billion km while on the other hand, the radius of the milky way galaxy is 52,850 light years which is very very large than the radius of our solar system. Milky way galaxy has 100–400 billion planets while in our solar system has only eight planets.

blood does not contain any antigens. The chart below shows the possible phenotypes of
each blood type.

B:

B
AB
Which mechanism explains how both A and B antigens produce type AB blood?
Answer:
codominance
Explanation:
The mechanism that explains how both A and B antigens produce type AB blood is codominance. In codominance, both alleles are expressed equally in the phenotype, which means that both the A and B antigens are present on the surface of the red blood cells in type AB blood.
what is antigen?The mechanism that explains how both A and B antigens produce type AB blood is codominance. In codominance, both alleles in a heterozygous individual are fully expressed in the phenotype. Therefore, in the case of blood type AB, the A and B alleles are codominant, and both antigens are expressed on the surface of the red blood cells.
Hence, The mechanism that explains how both A and B antigens produce type AB blood is codominance. In codominance, both alleles are expressed equally in the phenotype, which means that both the A and B antigens are present on the surface of the red blood cells in type AB blood.

Identify the tonicity of the solution surrounding the cell.
Answer:
Hypertonic
Explanation:
Hypertonic solutions have less water ( and more solute such as salt or sugar ) than a cell. Seawater is hypertonic. If you place an animal or a plant cell in a hypertonic solution, the cell shrinks, because it loses water ( water moves from a higher concentration inside the cell to a lower concentration outside ).

Scientists discover two planets orbiting a distant star. The average distance from the star to Planet A is 4 AU, and it takes 432 Earth days for Planet A to orbit the star. If it takes 1,460 days for Planet B to complete an orbit, what is the average distance from Planet B to the star?
Answer:
3.3
Explanation:
no reason for the explanation
Answer:
C. 9 AU
Explanation:
The period (T) of Planet A is 432365=1.2 Earth years. The period of Planet B is 1,458365=4.0 Earth years. Kepler's Third Law states that
a3=kT2
Substituting the known values of a and T for Planet A, we have
43=k⋅1.22
64=k⋅1.4
k=45.7
Using this value for k, we can solve for the distance from Planet B to the star
a3=45.7⋅4.02
a3=731.2
a=9.0AU
An alternative solution is to notice that a3T2=k for both orbits, which means that the ratio a3T2 is the same for both orbits. So, 434322=x314582. Solving this proportion gives x3=729, so x=9.0AU.

Osmosis requires energy
True
Or
False
Answer:
Diffusion and osmosis don't require the cell to expend any of its own energy, as they are passive processes. As we know both are passive processes and yet (in basic, short terms) diffusion is higher to lower and osmosis is lower to higher, so movement to concentration doesn't determine whether it is active or passive.

Answer:
Birds do not have teeth, however...Explanation:
[tex]--------------------------------------------[/tex]
According to The Cornell Lab, "Birds do not have teeth, however, they may have ridges on their bills that help them grip food, but this does not count as teeth. So what about birds that have “tooth” in their name, like Double-toothed Kite? Some birds of prey have a sharp ridge or “tomial tooth” on the bill that they use to bite into their prey when subduing it. But these modifications to the bill surface are not considered the same thing as individualized teeth seen in other animals."

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
