Involuntary, meaning things in the body such as your heart is all regulated to act unconsciously while also receiving directives from the brain.
I think the answer is A because direct sunlight causes dyes in clothes to fade quietly.
I'll say C, Science cannot answer difficult question...let me know.
Answer:
Interphase within sequences of cellular processes After the successful completion of mitosis and cytokinesis, both resulting daughter cells re-enter G1 of interphase. In the cell cycle, interphase is preceded by telophase and cytokinesis of the M phase.
Explanation:
Answer:
4) Replacement of GDP by GTP on the Ga after interaction with an activated GPCR.
5) Conformational change in the Ga subunit causing a decreased affinity for the Gb g subunit.
2) Dissociation of Ga from the G protein complex.
6) Ga-subunit with its attached GTP activates an effector like adenylyl cyclase.
3) Production of a second messenger, like cAMP.
1) Activation of one or more cellular signaling proteins.
Explanation:
It is a signaling cascade initiated by G proteins. These G proteins function as molecular switches capable of activating signaling pathways in the presence of guanosine triphosphate (GTP), which is hydrolyzed in order to produce energy
