GIVING BRAINLEST (ALSO POINTS) Cosmo is a scientist. He is conducting an experiment to determine if microscopic yeast particles are living organisms.

He divides a Petri dish into four sections and spreads a sample of yeast into each section. His Petri dish is pictured below.

Cosmo knows that yeast reacts chemically with sugar. So he adds different amounts of sugar to each section of his Petri dish. He is careful to keep each section separated from the others. In one of the sections, Cosmo does not add any sugar at all.

He waits one week and then carefully observes each sample of yeast under a microscope. He makes several observations. These observations are listed below.
Each sample of yeast remained separate from the other three samples.

The three samples that were given sugar showed evidence of a chemical reaction.

The sample that was given the greatest amount of sugar reacted with the sugar the most.

The yeast that received no sugar responded by forming and releasing spores.
Which observation provides the best evidence that Cosmo's yeast particles are living organisms?
A.
Observation #4
B.
Observation #1
C.
Observation #3
D.
Observation #2

A: Observation #4.

Explanation:

"Forming and releasing spores" is another term for reproduction. A spore is typically a single sell surrounded by a thick cell wall for protection. Once the spores are formed, the organism releases them into the environment to grow and thrive. And anything with cells are living organisms. A cell is the smallest unit of a living thing. Whether made of one cell (like the spores) or many cells (like a human) it is still an organism. So knowing that it is capable of reproduction, that means it is a living organism.

I HOPE THIS HELPS :)

c.tabloids tell me if i am right

1. read the following excerpt from franklin d. roosevelt's "fireside chat 19":

on the other side of the picture, we must learn also to know that guerilla warfare against the germans in, let us say serbia or norway, us; that a successful russian offensive against the germans us; and that british successes on land or sea in any part of the world strengthen our hands.

remember always that germany and italy, regardless of any formal declaration of war, consider themselves at war with the united states at this moment just as much as they consider themselves at war with britain or russia. and germany puts all the other republics of the americas into the same category of enemies. the people of our sister republics of this hemisphere can be honored by that fact.  

the true goal we seek is far above and beyond the ugly field of battle. when we resort to force, as now we must, we are determined that this force shall be directed toward ultimate good as well as against immediate evil. we americans are not destroyers — we are builders.
