Question

students are investigating living and nonliving organisms. the students observe objects that are found in a fish tank. they view each object with their eyes and then view a small sample from each object under a microscope. the picture shows the fish tank and their observations. does the object move? is the object made of cells? does the object contain a nucleus? is the object visible without a microscope? clear all

Explanation:

Living organisms are made of cells. To determine if an object in the fish - tank is living or non - living, checking if it is made of cells is a key characteristic. Movement is not a definitive characteristic as some living things don't move (like plants) and some non - living things can move (e.g., due to water currents). Not all living things have a nucleus (e.g., bacteria are prokaryotes). Visibility without a microscope is not related to being living or non - living.

Answer:

Is the object made of cells?
