Ok when we inhale we are letting oxygen inside of us, that oxygen that we inhale helps our blood move around our bodies. When we breath out taking out all the old air thats called carbon dioxide and it is very dangerous because it can make us stop breathing if we dont find new oxygen fast. Please if you need more info just private message me.
According to the question, the actual percentage concentration of phenylephrine hydrochloride is 1.
<h3>What is Percentage concentration?</h3>
Percentage concentration may be defined as a type of measurement of the amount of solute dissolved in every 100 units of solution.
According to the question, the amount of phenylephrine hydrochloride = 50 mg.
The volume of injection = 5 mL.
Percentage concentration = 
= 5/5 = 1.
Therefore, according to the question, the actual percentage concentration of phenylephrine hydrochloride is 1.

The oxygen in the upper atmosphere combine to form ozone layer (o3) that allows to colonize surface water.
Explanation:
The fossil stomatolites are formed at about 3.0 ga laminated bacteria. they form the sediments to fall into a thin film of bacteria, these bacteria binds with the sediment and grows through it.
Cynobacteria uses water, CO2 and sunlight to create their own food and produce oxygen as a by product. The significance of stromatolites is that they are earliest fossil evidence life on earth.
They were first organism to photosynthesis and produce oxygen.
<span>The answer is extracapsular cataract extraction (ECCE). It is
a kind of eye surgery in which the lens of the eyes are removed, leaving the
elastic capsule covering the lens which is left partially attached to let the
implantation of an intraocular lens (IOL). This approach is compared with
intracapsular cataract extraction (ICCE), an older procedure in which the
surgeon detached the complete lens within its capsule and left the eye aphakic
(without a lens). The patient's vision was corrected after intracapsular
extraction by extremely thick eyeglasses or by contact lenses. There are two
major types of ECCE: manual expression, in which the lens is removed through a slit
made in the cornea or the sclera of the eye; and phacoemulsification, in which
the lens is shattered into fragments inside the capsule by ultrasound energy
and removed by aspiration.</span>
