This should be most likely true
Answer:
<h3>The answer is 1.28 N</h3>
Explanation:
The force acting on an object given the mass and acceleration we use the formula
<h3>force = mass × acceleration</h3>
From the question
mass = 142 g = 0.142 kg
acceleration = 9 m/s²
We have
force = 0.142 × 9 = 1.278
We have the final answer as
<h3>1.28 N</h3>

Answer:
It helps microorganisms grow
Explanation:
I think this is the correct answer because I tried searching it up and you sterilise the petri dish before adding the agar, I've used agar in petri dishes a year ago and im pretty sure they don't make cells glow or make bacteria appear larger.
