The statement "The American Psychological Association is the only organization that can approve psychological research studies." is false.
Answer:
Option (4).
Explanation:
Phosphatidylinositol4,5-bisphosphate (PIP2) is the phospholipid present in plasma membrane. This lipid is important for the cell communication and cell signalling process.
The PIP2 can cleave and give two main products are DAG (diacylglycerol) and IP3 ( inositol 1,4,5-trisphosphate). These two molecules are important for the cell signalling.
Thus, the correct answer is option (4).
Answer:
a) because after the cleavage of the phosphate groups, the phosphate at the 5´carbon atom is ready to bind the oxigen from the OH- in 3´carbon en the incoming nucleotide
b) The DNA ligase will need an energy source because after removing the RNA, the 5´carbon will not have the three phosphates to be cleaved so that the energy of those unions can be used to catalize the new union
These two statements imply that an entity is considered as a living organism has at least one cell (the basic unit of life). It could be eucaryote or procaryote, unicellular or pluricellular. It has his own metabolism and its own genetic material.
Prions, viruses, and bacteriophages are not considered as a living organism, because they are technically not a cell, and does not all the property and the structure of a cell.
