Immune cells, specifically Antigen presenting cells, was an example of which type of communication

• Direct contact

• Local signaling (paracrine)

• Long distance signaling

• Local signaling (synaptic)

Ligands, such as growth factors, was an example of which type of communication

• Direct contact

• Local signaling (paracrine)

• Long distance signaling

• Local signaling (synaptic)

Seritonine is a neurotransmitter that is extremley important for healthy sleep. This is an example of which type of communication

• Direct contact

• Local signaling (paracrine)

• Long distance signaling

• Local signaling (synaptic)

A popular product for fruit and vegetable fans are 'Debbie green bags' which can be purachsed almost anywhere. Produce is placed in a bag that allows for the escape of ethylene gas, a hormone released by plants to ripen other nearby produce. This is an example of what type of communication?

• Direct contact

• Local signaling (paracrine)

• Long distance signaling

• Local signaling (synaptic)

Hormones released in the bloodstream is an example of what type of cell communication?
