Question

date:____ class period:__ characteristics of living things quiz after school, jordan wandered into the science lab to return a forgotten notebook. on the front counter sat something strange - a smooth, shiny sphere the size of a ping - pong ball. it gave off a small amount of heat, almost like it was alive. jordans curiosity kicked in. he remembers that living things share eight specific characteristics. he decides to run tests for each to figure out if the object is living or nonliving. with his science teacher, jordan carefully scraped a tiny sample off the object and placed it under the microscope. instead of cells, he only saw repeating patterns of minerals - no membranes or organelles. he left the sphere in a sealed container overnight. the next morning, it looked exactly the same - no duplicates or other offspring. jordan then shined a flashlight directly on it, then moved the light away. the sphere stayed completely still, with no change in position or shape. he placed it in a sugar solution, then in plain water. the sphere absorbed nothing, and its slight warmth didnt change. using the labs high power microscope, jordan found no trace of dna, rna or any nucleic acids. jordan then tried placing the object in slightly acidic water. instead of adjusting, the surface begins to dissolve slowly, showing damage rather than adaptation. when placed in a cooler environment, jordan noticed its temperature dropped quickly to match the surroundings. it couldnt regulate its own internal conditions. finally, over a few days, jordan measured the weight of the item over three days. the size, shape and mass stayed exactly the same. level 1 - 2 1. a) place a checkmark next to the characteristics to identify what this object is showing. made of cells __ reproduce offspring __ grow and develop __ obtain and use energy __ respond to the environment __ contain genetic material __ maintain stable internal environments __ as a group, they evolve __ b) place a checkmark next to the characteristics to identify what this object is not showing. made of cells __ reproduce offspring __ grow and develop __ obtain and use energy __ respond to the environment __ contain genetic material __ maintain stable internal environments __ as a group, they evolve ____

Explanation:

Jordan found no cells, no reproduction, no energy - use, no genetic material, no growth/development, no response to environment, no stable internal environment maintenance, and no evolution in the object. These are key characteristics of living things. Since the object lacks all these, it is non - living.

Answer:

A) None of the characteristics should have a checkmark as the object is not showing any of the characteristics of living things.
B) None of the characteristics should have a checkmark as the object is not showing any of the characteristics of living things.
