Answer:
El Niño is defined as an unusual weather pattern seen in the Pacific Ocean. In this weather unusual winds allows the surface water to get warm from the equator to move east, that is toward Central and South America.
So, El Niño affects wind shear, in which air current present in lower altitude moves to different direction from winds higher in the atmosphere and affects weather patterns. such as El Niño is responsble for more rain in South and Central America and in the United States.
The drug solution has a concentration of 100 mg/15 mL and the needed dose is 25 mg. There should be computation of the required volume. The computation is as follows:
Volume = (25 mg)/(100 mg/15 mL)
Volume = (25 mg)/(6.67 mg/mL)
Volume = 3.75 mL
The patient needs to take 3.75 mL of the drug with a concentration of 100 mg/15 mL to get a dose of 25 mg. A measuring cup (or a little cup) may be used as these measuring cups are calibrated to match volume dosages.
Answer:
Polymer of nucleotides is acidic in nature due to phosphate groups.
Explanation:
Nucleic acids are polymers of nucleotides. Each of the nucleotides contains one nitrogenous base, a pentose sugar, and a phosphate group. The polymerization of nucleotides occurs by the formation of phosphodiester bonds between them. The sugar-phosphate backbone with alternating sugar and phosphate groups is exposed to the surrounding medium while the nitrogenous bases are stacked upon each other in the interior away from the watery medium.
The phosphate groups are completely ionized and bear negative charge at the neutral pH making the polymer of nucleotide acidic in nature. The alkaline nitrogenous bases are not exposed and stacked towards the interior of the helix.
