Answer: Option B
Explanation: First we should understand the role of enzyme and acid here. Pepsin is an enzyme which will break down proteins into simple monomers (like amino acids). And, acid causes digestion which means it will break down the protein into its respective elements and compounds. Water will act as a control in this experiment.
Option B is correct because it has all three criteria- 1. Control [water + protein] 2. With enzyme [egg white + pepsin] 3. With acid and enzyme
So this will give us an idea whether pepsin alone is breaking down the protein or digesting it. And there would be difference in test tube B and C. So this will clear the difference.
Option A is incorrect because it has not mentioned any different test tube for checking what happened with the protein. And, Option C is incorrect because mass of egg white will remain same after digestion also.
Answer:it described how carbon is recycled between earth's biosphere, hydrosphere, geosphere and atmosphere. Carbon is an essential element for all life forms so understanding how it is recycled will help us to understand factors and all the biological processes that influence them.

b) Lysosome
Explanation:
After ingestion of a food particle, pH changes and enzymes contributed by the __Lysosome__ will digest and hydrolyze the ingested particle in the phagocytic vacuole.
Answer:
A motor unit is a group of MOTOR NEURON and the MUSCLE FIBERS connected to it.
Explanation:
Neuron is the structural and functional unit of nervous system.
Motor unit consists of a motor neuron and the skeletal muscles innervated by the terminals of the neuron.
Several associated motor units called motor pool coordinates together the contractions of a single muscle.
That is, the activation of a motor unit leads to the contraction of all the muscle fibers attached to it.
