The answer is A as this is how we discovered alleles and their dominant/recessive nature.

Theoretically if traits were controlled by only 1 gene then every time you bred 2 purple flowers together you would always get offspring that are also purple, but if there were 2 genes and these 2 flowers had recessive white alleles then some offspring would be white.

A patient is receiving gentamicin once daily. A nursing student asks the nurse how the drug can be effective if given only once
Digiron [165]

Answer:

a."Gentamicin has a longer half-life than other aminoglycosides."

Explanation:

Gentamicin is an aminoglycoside that binds to bacterial ribosomal proteins and causes the inhibition of the protein synthesis, killing the bacteria. The killing can continue for long periods after administrating the drug and even once that the concentrations of this one can no longer be detected in the plasma. That is the reason why this drug is given once a day.

All of the following are ways in which carbon dioxide is carried by the blood EXCEPT:
liq [111]

Answer:

bound to oxyheamoglobin

Explanation:.

Oxyheamoglobin is formed from the reaction of oxygen with haemoglobin.it is the oxygen loaded form of haemoglobin for delivery of oxygen to needed remote areas of the body.

.Hb        +      4O2       ⇒    HbO8

haemoglobin  oxygen    oxyhaemoglobin

Haemoglobin is a protein molecule that binds with oxygen. It has high affinity for oxygen with its four haem groups. Each haem group has binding iron.(Fe). When it is binds  with oxygen it is bright red, and turns purple when it unloaded oxygen at target point.

It has no association with carbondioixde transports except oxygen transport .

Carbon dioxide, is transported as the  listed three options(b,c,d) in the questions. Therefore  bound to oxyheamoglobin is  wrong, and it is the correct answer
