When the bar is pulled down, the only numbers that are relevant are 4, 5, and 6.
This is further explained below.
<h3>What are Emergency Medical Technicians? </h3>
Generally, A health care worker who performs emergency medical services is called an emergency medical technician, which is also often referred to as an ambulance technician. Ambulances are the settings in which one is most likely to find an EMT at work.
In the majority of jurisdictions, being certified as a paramedic is the greatest level that may be achieved. However, some states provide certification for advanced paramedics as well as paramedic certification for nurses and physician assistants.
In conclusion, with the pull-down of the bar, all that apply are 4, 5, 6

Answer:
location
, events
Explanation:
A three dimensional universe is comprised of three measurements, width, breadth, and height.
In a three-dimensional universe, the position of a spacecraft is defined by its location. In a four-dimensional system, the spacecraft defines a line that represents events through which the object passes.
Answer:
hydroxylation of phenylalanine to tyrosine
Explanation:
Phenylketonuria is an inherited disease that results from the lack of the enzyme phenylalanine hydroxylase (PAH), which catalyzes the hydroxylation of phenylalanine go tyrosine. A build up of phenylalanine could result to mental instability , intellectual problems and seizures. This is because of the body’s inability to convert phenylalanine to tyrosine.
Tyrosine is an important amino acid which helps in the production of neurotransmitters which ensures proper functioning of the brain cells.
Answer: B) The number of electron in its valence shell.
Explanation:
Outermost electrons of the atoms which can participate in the chemical bond formation is known as valence electrons.
Atoms either transfer or share its valence electrons during chemical bond formation. Atoms transfer or share electrons to attain octet or in other words stability.
Generally, 8 electrons are required in their outermost shell or valence shell in order to attain stability. This rule is known as octet rule.
For example, general electronic configuration of sodium belonging to group 1 is 1s2 2s2 2p6 3s1.
No. of valence electrons in Na = 1
by loosing 1 electron, its outer shell electronic configuration become = 1s2 2s2 2p6 (Octet)
Hence, sodium and other group 1 elements are very reactive.
Similarly, halogens (ns2 np5) by gaining 1 electron attain octet (ns2 np6). Hence halogens are also very reactive.
Carbon atom belonging to group 14 has 4 valence electrons (ns2 np2) and share all 4 valence electrons to attain octet and hence reactive.
Nobel gases have octet in their outermost shell (ns2 np6), hence they are most nonreactive element.
