Among the choices, the only unicellular organism is bacteria. <span>The bacteria has no nucleus, and no distinct organelles. </span>Bacteria only has one cell, where all of its life processes take place, like respiration, ingestion, and excretion, so it can survive only as a single cell.
Answer:
The reaction force is the force exerted by your body on the earth pulling upwards.
Explanation:
This can be explained using Newton's third law of motion which states that if object A exerts a force on object B, object B exerts a force of equal magnitude and opposite direction on object A. One characteristics of these force are that they act o 2 different bodies. In this example, the earth exerts a force on you. The Newton's reaction force would be you exerting a force of equal magnitude on the earth.
Answer:it might be radiation
Explanation:
Answer:
Final velocity of the car will be -9.28 m/sec
Explanation:
We have given that the car starts from the rest so initial velocity of the car u = 0 m /sec
Acceleration of the car 
in negative direction so acceleration will be 
From first equation of motion we know that
v = u+at
So 
So final velocity will be -9.28 m/sec
Reactivity is the ability of matter that allows it to easily chemically combine with other substances.
