classify the object as a living thing?
SELECT ALL THAT APPLY
a The object grows and develops.
b The object moves.
c The object reproduces.
d The object maintains homeostasis.
e The object is made of one cell.
Answers
Answer: a,b,c,d
Explanation:
all four of them are characteristics in all living organisms. All living things will grow and change, it will move otherwise it wouldn’t be able to get the nutrients it may need (or run away from predators), in order for the species to go on, they must reproduce, and they must maintain homeostasis so that they don’t freeze of burn to death. but however, it is not required for the living organism to be made up of only one cell, take humans for example.
The correct characteristics of a living thing are:
a The object grows and develops. c The object reproduces. d The object maintains homeostasis.There are several traits used to classify objects or things normally as living things and objects or things without these traits are classified as non-living. The some of characteristics of living organisms are:
consist of one or more cells reproduction homeostasis metabolism response to stimuli or environment growth and developmentTransfer of genetic materialThere are some more traits that are not true for some of the organisms or living things.
