Answer:
1. Air mass is temperature or humidity
2. The two ways are temperature and humidity
3. Continental Polar and cP
4. Maritime Tropical and mT
5. Continental Tropical and cT
6. Arctic air masses are very cold and polar air masses are not as cold
7. Wind is movement in the air
8. It is called the Great Equalizer because of a storm that caused stockmen to lose herds
9. Pressure impacts the direction of the wind because the faster the wind blows the higher the pressure.
10. The general movement of the earth
The last two you are going to have to do on your own because I cant draw.
Answer:
Referred pain
Explanation:
Referred pain may be defined as the pain perceived at differnet location of body other than the individual pain location.
Referred pain depends upon the intensity and duration of the pain. Refereed pain is generally generated by the potent mechanism of temporal summation. Referred pain is the condition of the body in which the uninjured body part experiences pain due to the injury of another body part.
Thus, the correct answer is option (b).
Answer:
The correct answer is : A.
Explanation:
- This is because of the following reasons:
- Escherichia coli is a bacteria and hence is a prokaryote.
- The cloning of human (eukaryote) genes is done to obtain in-vitro protein expression which are to be used a pharmaceutical compounds.
- Although the phenomenon of Central Dogma takes place in both Prokaryotes and Eukaryotes, the mechanism is very different.
- Some of the differences includes:
- Eukaryotic genes contain certain non-protein encoding sequences called the Intron sequences which needs to be removed from the transcribed mature mRNA by Spliceosome. This phenomenon is absent in prokaryotes as they do not possess introns. Hence, proper processing of eukaryotic mRNA is not possible in prokaryotes.
- The mature eukaryotic mRNA has a 5' cap and 3' polyadenylated tail which is added by a capping enzyme and a poly-A polymerase enzyme to increase their stability. This will not be possible in a prokaryote as they lack these enzymes.
- The translation of membrane proteins and secretory proteins is carried on by the ribosomes bound to the endoplasmic reticulum. This structure is absent in prokaryotes, hence they will be unable to produce a proper polypeptide sequence.
- Finally, the eukaryotic proteins undergo various modifications after formation, like methylation, acetylation, etc. These reactions cannot be carried out in a prokaryote as they lack the respective enzymes.
- Hence, we see a properly folded functional eukaryotic protein cannot be produced in a prokaryote.
