Scientists have discovered a colony of potential organisms on the Planet Moby and named them "Maxoids." Read the information below that scientists have gathered on Maxoids and decide whether Maxoids are living or nonliving things. Explain how you came to this conclusion.

Through testing and observation, scientists have recorded the following characteristics of Maxoids. Maxoids reproduce via sexual reproduction. One parent carries the Maxoid eggs for 12 weeks before they hatch. After hatching, juvenile Maxoids continue to grow for seven months. To acquire energy for growth, Maxoids consume a peculiar liquid substance native to the planet Moby. The Maxoids' cells use this energy, as well as large amounts of water, to carry out important functions. The Maxoids are sensitive to changes in internal temperature. Sometimes they dig holes and lay in them to cool down if they get too warm.

Answers

The Maxoids are living things because they possess the characteristics of living things.

What are living things?

Living things are identified by the characteristics which make them living.

The characteristics of living things include:

Movement - living things are able to move all or parts of their bodyRespiration - living things are able to break down food substances to produce energyNutrition - living things are able to take in food substancesIrritability - living things are able to respond to changes around themGrowth - living things are able to increase in size and massExcretion - living things are able to remove waste substances from their bodiesReproduction - living things are able to produce new ones of their kind

Considering the Maxoids;

They are able to reproduceThey take food in the form of a liquid substanceThey are sensitive to changes in internal temperature

In conclusion, the Maxoids are living things.
