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 :)

the answer is c: at the city park,it has two basketball courts, a playground, and a walking path.

hello everyone my name is nevaeh, i know everyone needs in some way, shape, or form and i am willing to provide. i set up a google classroom where people can ask me questions and get on work. no question is a stupid question so do not be afraid to ask. i usually only focus on core subjects but if you ask i will with other specialized subjects. i can do essays all the way to power points : )

my google classroom is the code is 7hr2k4

~ use this opportunity to get more so you can thrive in the classroom
