Answer:
In order to be able to make proteins, RNA has to migrate or travel to the cell cytoplasm.
Explanation:
RNA, specifically messenger RNA (mRNA) is responsible for carrying the genetic information needed for make proteins, so it must migrate from the cell nucleus to the cytoplasm.
DNA transcription and RNA synthesis, as well as maturation, occur in the cell nucleus. From there, the mRNA must travel to the cytoplasm to meet the ribosomes and initiate protein synthesis.
The electrons are outside the nucleus and have a negative charge?
Answer:
Correct!
Explanation:

if there's 23% cytosine how much adenine
I'm going to tell you how to find the answer yourself so you can figure out other problems like it.
First, DNA is made up of those four nucleic acids. Adenine always pairs with Thymine in DNA. Guanine always pairs with Cytocine.
Therefore, the amount of Adenine will always equal the amount of Thymine in DNA. The amount of Guanine will always equal the amount of Cytocine.
So, if Adenine equals 23% of your sample and Adenine equals Thymine, then Thymine equals 23%.
Add the amounts of Adenine and Thymine. 23% + 23% = 46%
100% - 46% =
That gives you the percentage of Cytocine and Guanine together. Since they are in equal amounts, divide by two and you have the percentage of each.

The cell theory states that all living cells come from pre-existing cells. If that's true then, how did the first cell originate?
1 not enough information is given
2 Nature created the first cell.
3 The first cell originated spontaneously.
4 This postulate of cell theory is false.
Answer:
option 2 and 3 are seems to be correct.
Explanation:
according to our studies the options and 3 are seems to bee correct because the first cell was created by nature not by man or any other organism and the term spontaneously also look to be true. so my answer is that options 2 and 3 are correct.

3 process that directly add carbon dioxide to atmosphere?
Answer:
Carbon dioxide is added to the atmosphere naturally when organisms respire or decompose (decay), carbonate rocks are weathered, forest fires occur, and volcanoes erupt. Carbon dioxide is also added to the atmosphere through human activities, such as the burning of fossil fuels and forests and the production of cement

Stage one
Stage two
They produce an equal amount of energy
The answer is Stage 2
why are region called promoters essential to RNA transcription?
Answer:
A promoter is a region of DNA where transcription of a gene is initiated. Promoters are a vital component of expression vectors because they control the binding of RNA polymerase to DNA. RNA polymerase transcribes DNA to mRNA which is ultimately translated into a functional protein.
hope that helps :)

Why is red light the best for photosynthesis?
Answer:
The primary reasons why LED fixtures emit a lot of red are 1) red LEDs are among the most efficient at converting electricity into photosynthetic photons, 2) chlorophyll strongly absorbs red light, thus it is effective at photosynthesis, and 3) red LEDs are relatively inexpensive
what is the role of a catalyst?
Answer:
Catalysts make such a breaking and rebuilding happen more efficiently. They do this by lowering the activation energy for the chemical reaction. Activation energy is the amount of energy needed to allow the chemical reaction to occur. The catalyst just changes the path to the new chemical partnership

what are some potential consequences of the widespread use of plastic materials
Answer:
Consequences of the widespread use of plastic materials can be an increase in levels pollution and the overflowing of landfills because most plastics are non-biodegradable and can take a very long time to disappear unlike things like paper which are biodegradable.

In the rat, the allele for red eye colour is dominant over the alleles for brown colour. Consider a cross between a rat that is an Hozygote dominant for eye colour and a rat that is an Hozygote recessive for eye colour.
1. Show the parental genetic cross between the two rats.
2. Use a Punnett square to show the F1 (filial generation).
3. Indicate the genotype and phenotype of the F1 generation.
4. With the results of the F1 generation, construct a Punnett square showing the results of an F2 (generation).
5. Indicate the genotype and phenotype of the F2 generation
Answer:
1) RR x rr
2) Shown below
3) 100% Rr with red eyes
4) Punnett square shown (Rr x Rr)
5) 25% of the offspring are h0m0zygous dominant with red eyes (RR), 50% are heterozygous with red eyes (Rr), and 25% are h0m0zygous with brown eyes (rr)
Explanation:
Let's say the allele for red eyes is R and the allele for brown eyes is r.
1. A cross between a h0m0zygous dominant (two copies of the dominant allele, R) and h0m0zygous recessive (two copies of the recessive allele, r) is: RR x rr
2. R R
r Rr Rr
r Rr Rr
The F1 generation is shown in the Punnett square above.
3. The F1 generation are 100% Rr. They are heterozygous. Since red (R) is dominant, the rats all have red eyes
4. A cross between the F1 generation (Rr x Rr) gives the F2 generation
R r
R RR Rr
r Rr rr
5. 25% of the offspring are h0m0zygous dominant with red eyes (RR), 50% are heterozygous with red eyes (Rr), and 25% are h0m0zygous with brown eyes (rr)
An atom of argon contains 18 electrons. Describe how these electrons would be arranged. You may find
it helpful to draw a diagram.
Argon is a gas at 20°C (room temperature). Predict which state neon is at this temperature and give a
reason for your answer.
Answer:
a. The electrons are configured in a 2-8-8 order with 8 valence electrons. There are three full shells.
b. Because Argon and Neon are in the same group, they have very similar properties, so we can guess they would be in the same state. Neon would be a gas.

Which kind of root system would more likely benefit a desert plant----a taproot or a fibrous root system? Why?
Answer:
A taproot
Explanation:
A taproot will most likely benefit a desert plant because a taproot is a large long root that gets deep into the soil because in a desert the soul isnt fertile and is also sandy so a fibrous root system would be less beneficial because it will absorb less nutrients and will have a hard time clinging on a sandy soil while a taproot can reach further into the fertile part of the soil.
