Answer:
The correct answer will be- relationship between facial movements, facial expressions and emotions.
Explanation:
The Facial Action Coding System (FACS) is a comprehensive system used to study the facial expressions and relating them to the emotions.
This coding system was developed by a psychologist named Paul Ekman which is used by the detective agencies to detect lies and the animation industries all over the world.
The system is based on the anatomical facial movement which is broken down into the smaller components called Action Units based on the muscles movements.
Thus, the relationship between facial movements, facial expressions and emotions is the correct answer.
Answer:
the mRNA goes through extensive modifications such as addition of a poly tail and a 5' cap in eukaryotes but not in prokaryotes.
Differences:
- the promoters in prokaryotes have a -35 and -10 box while in eukaryotes they are variable but have a TATA box from
- the transcription initiation site there is a single RNA polymerase in prokaryotes while eukaryotes have multiple RNA polymerases
- the sigma factor associates with the promoter region in prokaryotes but in eukaryotes there are many basal transcription factors
Explanation:
Ribosomal and transfer RNAs are processed both in prokaryotic and eukaryotic organisms. However, mRNA is only processed in eukaryotes. In eukaryotic cells, mRNA processing involves:
1. Capping at the 5' end. This process has several functions including regulation of nuclear export, prevention of eukaryotic mRNA degradation and promotion of translation.
2. Splicing in order to remove introns and conserve coding exons. Splicing helps to increase the diversity of the eukaryotic mRNAs (and therefore eukaryotic proteins)
3. Polyadenylation by the addition of a poly(A) tail at the 3' end. The poly(A) tail makes the eukaryotic mRNA molecule more stable and also prevents its degradation by exonucleases.
The dominant hand will most probably be faster to react and will also react more strongly in comparison to the non-dominant hand. The reason for this is that our dominant hand tends to be better at reacting towards stimuli in comparison to our non-dominant hand.
The nutrients in some soils could be toxic to microorganisms/fish in those ponds or lakes.
