Answer: Blood is slightly more viscous then water, pH is slightly alkaline it is about 8% of ones body total body weight the rest of the options are slightly wrong.
Explanation: Blood is red in colour, a dark red when it is deoxygnated and bright red when oxygenated. Its normal pH is 7,4 making it slightly alkaline and it accounts for 8% of one's total body weight with 92% being water. Its temperatures ranges around our normal body temperature which is 37°C.
Answer:
C) provides the instructions for making proteins
Explanation:
Ans.
Lac (lactose) operon in a type of bacterial operon, which shows a cluster of genes that are regulated by a single promoter. It is composed of an operator, promoter, a terminator, and three structural genes (lacA, lacY, and lacZ), which are responsible for the transport and breakdown of lactose.
The lac operon is an inducible operon as it gets activated in the presence of lactose and expressed its functional genes in the form of proteins (or enzymes) for lactose metabolism.
Thus, the correct answer to be fill in first blank is 'inducible' and in second blank is 'lactose.'
