Cold stun or by predator attack
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
Sustainable land management (SLM) refers to practices and technologies that aim to integrate the management of land, water, biodiversity, and other environmental resources to meet human needs while ensuring the long-term sustainability of ecosystem services and livelihoods.
Pine trees have deep roots which enable them to adapt to the climate of the northwestern coniferous forests. Their roots extend deep down to the soil where oxygen content is limited and water is scarce. During the change of seasons when the soil is wet the roots tend to recede and when it is dry the roots tend to spread downward.
