Choose the answer half-life, im sure it is correct
Answer:
Correct choice should be:
"SGSG"
Explanation:
The cell cycle consists of G1, S, G2 and M phase. The former three phases include the interphase and M phase is the dividing phase of cell . G1 prepares cell for DNA synthesis. S phase is the phase where DNA replication takes place. G2 phase prepares cell for cell division or M phase.
G1 phase preceeds replication or S phase and G1 phase licences DNA replication.
During other phases of cell cycle, ORC complex masks origin of replication. ORC phosphorylation takes place at S phase, which removes this omplex and unmasks origin of repication site so that replication machinery can bind to it.
DNA helicase activation: S phase
DNA helicase deposition on DNA at the replication origins: G phase (actually G1)
ORC phosphorylation: S phase
Licensing of replication origins : G phase (actually G1)
Hence correct choice should be:
SGSG
Answer:
Once you begin swallowing, the process becomes automatic. Your brain signals the muscles of the esophagus and peristalsis begins. Lower esophageal sphincter. When food reaches the end of your esophagus, a ringlike muscle—called the lower esophageal sphincter —relaxes and lets food pass into your stomach.
Answer:
Subpapillary plexus nourishes the dermal papillae and epidermis.
Explanation:
The superficial subpapillary plexus could also be regarded to as superficial plexus
. It is composed of postcapillary venules found at the junction of the papillary and reticular dermis and the lower plexus at the dermal subcutaneous interface. It lies below the dermal papillae, and supplies the capillaries in the dermal papillae. The pink color of skin is mainly due to the blood seen in venules of this plexus.
