Answer:</h2>
Removal of the tarnish from the silver is a <u>physical change</u>.
<h2>
Explanation:</h2>
The type of change which doesn't produce any new substance is called as physical change. Tarnish refers to the thin black layer that is formed on the silver. Formation of tarnish is chemical change as due to oxidation a black color layer is formed.
On the other hand, removal of tarnish from silver is considered as physical change as no new product is formed and only we are obtaining the silver in its pure form.

Answer:
The form of circulatory shock known as hypovolemic shock is the condition when the plasma level of blood and the body fluids level is decreased rapidly causing insufficient level of oxygen in the blood . the form of shock caused by anaphylaxis any condition in which blood vessels are inadequately filled and blood cannot circulate normally shock that results from large-scale loss of blood volume, or after severe vomiting or diarrhea always fatal
Explanation:
- hypovolemic shock is one type of shock among different kinds of shock. it happens when body fluids or blood plasma level starts to decrease rapidly due to some internal or external injury such as bleeding, dehydration, burns, and severe vomiting, diarrhea.
- later causes body fluid loss which decreases the o₂ level in blood.
- this causes lack of o₂ supply in organs which is indeed a fatal condition.
There are choices for this question namely:
<span>A) benztropine (Cogentin)
B) dantrolene (Dantrium)
C) clonazepam (Klonopin)
D) diazepam (Valium)

The correct answer is "Benztropine (Cogentin)". The administration of the typical antipsychotic Chlorpromazine may cause side effects characterized as involuntary repetitive movements called tardive dyskinesia (extrapyramidal symptom). The drug Benztropine is an anticholinergic drug that blocks the action of acetylcholine (as well as dopamine) in the central nervous system, restoring the neurotransmitter homeostasis.
Answer:
The correct answer is RNA polymerase does not require a primer to add new nucleotides.
Explanation:
RNA polymerase is an important enzyme of transcription process that deals with the formation of mRNA from DNA. unlike DNA replication, transcription process does not require any RNA primer to carry out the synthesis of mRNA in 5'→3" direction.
RNA polymerase use coding strand of DNA molecule as a template to synthesize new mRNA molecule from that parental DNA molecule.
