The idea that all living things are composed of cells and that all cells come from other cells defines the cell theory.
Hope this helps! :)
An agonist exhibit a positive biological effect similar to the receptor it stimulates. For instance, beta agonists (i.e. Salbutamol) stimulate the beta receptors in the bronchial system therefore leading to bronchodialtion. A competitive antagonist negates the function of the specific receptor by binding to the receptor binding site before the biological ligand. A non-competitive agonist negates the function of the specific receptor by binding to an allosteric site leading to a conformational change of the receptor site.
On number one you could say dirt seeing as dirt is another word for earth because it makes up earth
Osprey are a type of Hawk, which can kill small rodents, other birds and possibly small pets like cats. Although Osprey usually stay away from humans as most feral birds do if provoked they can fight back. They have claws and a sharp beak so it is recommended to leave them alone due to this. You should stay away from all wildlife regardless of how friendly they appear to be because they could carry dieses that make that act differently.
