Answer:
Ligand-receptor interaction is the first interaction that triggers cell signalling.
Explanation:
Ligands are the hormones, drugs or neurotransmitters that specifically bind with receptors present in cell surface to initiate cell signalling. Ligand binding to the receptor is reversible. Binding of the ligand to the receptor can activate or inactivate receptor. Activation may lead to cell signalling pathways. Inside cells, there are secondary molecules which on activation starts a cascade of reactions. which in-turn regulate the function of the ligand molecule.

Answer:
Cyclin is a family of proteins that controls the progression of a cell through the cell cycle by activating cyclin-dependent kinase (CDK) enzymes or group of enzymes required for synthesis of cell cycle.
This devastation has wrecked many ecosystems. The state has lost 90 percent of our coastal wetlands and inland wetlands, 99 percent of our riparian areas, and most of our native grasslands. California is also a critical nexus for the biodiversity loss taking place in our oceans.
There would be things everywhere because it didn't decompose ex. orange peels, banana
