Answer:
<h2>A polyadenylation signal or poly(A)
</h2>
Explanation:
Termination. In eukaryotes, transcription is terminated differently for the all 3 different RNA polymerases. Transcription is terminated by two elements: i) a poly(A) signal and ii) a downstream terminator sequence.
In eukaryotic protein-encoding genes, the cleavage site in the RNA occurs between an upstream( the sequence before the cleavage site) AAUAAA and a downstream GU-rich, separated by approx 40-60 nucleotides. After they both have been transcribed, a protein knows as CPSF and another protein called CstF( in humans) helps in termination.
The element carbon makes long chains forming, single, double or triple bonds with itself.
Answer:
1. Liver
2. Liver and Kidneys
3. Mitochondria
4. Lumen of the small intestines
5. Liver
Explanation:
1. Glucose is phosphorylated into glucose-6-phosphate which is the first step of both glycogen synthesis and glycolysis, this process occurs in the liver
2. Glucose 6-phosphate is a product of a process named gluconeogenesis which occurs in the liver it serves as a substrate for glucose-6-phosphatase in the liver.
3. Creatinine kinase is an enzyme that catalyzes the phosphorylation of creatine. In regeneration process of ATP, creatine phosphate transfers a high-energy phosphate to ADP which produces ATP and creatine
4. Initially lipase digestion lipase digestion happens in the small intestine where the bile salts reduce the surface tension of the fat droplets allowing the lipases to attack the triglyceride molecules. These molecules are taken up into the epithelial cells that line the intestinal wall, where they are resynthesized into triglyceride
5. The job of the liver is to produce ketone bodies. If the liver had this enzyme, the ketone bodies it produces would be immediately broken down by the liver before they are released, thereofore, no release of ketone bodies into the bloodstream
Buccinators are muscles in the cheek that help smiling.
Laris oculi are muscles helping close eyelids.
Orbicularis oris is a muscle that helps manipulate the mouth:
the correct answer is D. all the above are muscles that help facial expression.
Answer:
A. Duodenum
Explanation:
Duodenum is the first part of the small intestine which receives bile juice, pancreatic and intestinal digestive juices. The digestive enzymes present in these juices completes the process of digestion.
The lining of the duodenum has numerous finger-like projections called intestinal villi. The villi are specialized to absorb the digested food by providing increased surface area for the process of digestion. Hence, among the given options, the absorption of digested food occurs in duodenum.
