Choose all the examples of exocytosis. □ □ A nerve cell releases peptides used as messengers into the extracellular space. urine leaves a mouse's bladder and soaks into the soil. Proteins used as hormones are moved out of the cell in which they were manufactured. Oxygen moves out of a red blood cell through the cell membrane.

Ecology is the study of the relationships between living organisms, including humans, and their physical environment; it seeks to understand the vital connections between plants and animals and the world around them. Ecology also provides information about the benefits of ecosystems and how we can use Earth’s resources in ways that leave the environment healthy for future generations.(Ecological Society of America Website) Q1. Recent fires have devastated large parts of California. What are some ecological interactions that may have contributed...
