<em>A constant is something whose value cannot be changed and is used for comparison purpose. </em>
<u>Explanation:</u>
The controlled variable is a type of variable whose value is kept constant during the experiment to get the desired or expected result. The difference between constant and a control variable is that the constant can never be changed.
However, the value of control variable can be changed but is kept constant with a purpose in an experiment to get the data. The controlled variable in a battery can be the multi meter that should be used for all the batteries.
The reason why its false is because a person can't fight diseases with acids. there is something your body has called Antibodies. Also acid would only make it worse
Unicellular organisms or single celled organisms that are made up only of one cell. Hence the name.
Unicellular organisms are further divided into Prokaryotic and Eukaryotic organisms
Examples of prokaryotic organisms are bacteria and Eukaryotic are protozoa and unicellular algae, however many eukaryotes are multi cellular as well.
These organisms have to carry out life sustaining metabolic processes for their survival.
These processes are metabolism, homeostasis and reproduction. Metabolism is important as it involves conversion of food into energy for cellular processes. Homeostasis for maintaining a constant internal physical and chemical conditions and reproduction is by cell division.
Multi cellular organisms as the name says unlike unicellular organisms consists of more than one cells.
Examples of multi cellular organisms are animals, land plants etc.,
Metabolic process in multi cellular organisms is a broad category of processes happening for these organisms which involves chemical reactions and pathways that happen at organismal state, transporting substances between the cells.
