Answer: It is called Parasitism.
Explanation:
Parasitism is symbiotic relationship where an organisms lives in or on it's host thereby feeding and causing harm on it host. Examples of such relationship is parasites like roundworm, ticks, fleas that feed on humans and cause harm.
Answer:
they bind to protein-coupled transmembrane receptors with higher complexity than those found in prokaryotes
Explanation:
G-proteins are proteins found inside the cells that function as molecular switches which are activated by binding to guanosine triphosphate (GTP), while they are inactive by binding to guanosine diphosphate (GDP). The G-proteins bind to G-protein-coupled transmembrane receptors (GPCRs) in the cytoplasmic region. The GPCRs are a very diverse group of proteins that are activated by extracellular molecules ranging from small peptides to large proteins, including pheromones, neurotransmitters, light-sensitive compounds, etc, thereby allowing them to respond to diverse stimuli from the extracellular environment. In consequence, it is reasonable to suppose that the signaling pathways in which G proteins are involved have a higher complexity level than those observed in primitive prokaryotic organisms.
Answer: The hot weather cases the cold pool water to evaporate.
Hope this helps! I didn't have much to work with sense you didnt give options :)
