Explanation:
The genome of prokaryotes has no introns hence their mRNA does not need splicing like in eukaryotic cells. Also, because the genome of prokaryotes is not delimited from the cytoplasm by a nuclear membrane, ribosomes can attach to the elongating mRNA during transcription and begin translation. Therefore translation of mRNA occurs concurrently with transcription which cannot happen with eukaryotic cells.
In the nucleus of eukaryotic cells, transcription results to a nascent mRNA which is spliced into a mature mRNA.The mature mRNA has to travel outside the nucleus to the cytoplasm to be translated by ribosomes.

Answer:
Explanation:
We are asked to find the energy given mass, specific heat, and change in temperature. Therefore, we must use this formula;
The mass is 15 grams and the specific heat is 0.129 J/(g×°C). Let's calculate the change in temperature.
- ΔT= final temperature - initial temperature
- ΔT= 85 °C- 22°C = 63°C
Now we know all the values:
Substitue the values into the formula.
Multiply the first numbers together. The grams will cancel.
Multiply again, this time the degrees Celsius cancels.
<u>121.905 Joules</u> are required.
The principles of probability can be used to predict the outcomes of genetic crosse
Answer:
C
Explanation:
The brother has different alleles for the blood type gene than his sister does. Blood type is inherited from parents like many other traits that can be displayed on a punnet square. Depending on what the parents blood type alleles were, the brother and sister could have different blood types.
A different number of chromosomes doesn't lead to different blood types, so D is wrong. And A is incorrect because the number genes also does not affect blood type. And I think the blood type genes are on the same chromosome, so B is wrong. C is correct because blood type is inherited by alleles, and different alleles can cause different traits, such as blood types.
