Question

table 1: observations shows five objects that the student collected from the water and the initial observations of the objects.
table 1: observations

object	color	shape and texture	location
b	green	delicate, very thin	floating
c	gray	long and thin	moving in water
d	pale yellow	round, very small	floating
e	white	irregular shape, rough outer coating	on bottom of pond

how can the student gather data to provide evidence about whether each object is living?
options:

• observe the object to see whether it moves.
• observe the object to see whether it eats.
• use a microscope to look for eyes.
• use a microscope to look for cells.

Explanation:

To determine if an object is living, a key characteristic of living things is being made of cells. Movement (some non - living things move, like water currents moving objects), eating (hard to observe directly for small or simple organisms), and having eyes (only complex organisms have eyes) are not reliable indicators. Using a microscope to look for cells is a fundamental way to check for the basic unit of life, which is a strong indicator of a living organism.

Answer:

The correct option is: Use a microscope to look for cells.
