Answer:
A. Glucose:
As lactose is absent will follow the glucose metabolism, so the lac repressor will hold tightly with the operator which leads to the prevention of transcription as RNA polymerase can not bind to promoter so no lactose metabolism.
B. lactose:
In the case or wild mutant lactose metabolism will occur as lactose is present, allolactose binds to the lac repressor thus the operator and promoter are free so transcription starts. The same result will be in all test except in the case of a mutant repressor.
C. glucose and lactose:
In this case, diauxic growth will occur. This growth takes place when two sugars are present in the media. The preferred sugar will be consumed first That is glucose. Then a lag phase will come which will be followed by the second sugar metabolism that is lactose. the given two cases :
Lactose will be metabolized first, as operator site mutation prevents repressor protein binding and thus will lead to the constitutive synthesis of lac operon in test B.
The same thing will happen, as in this case also, constitutive synthesis of lac operon will happen in test C.
Cultures grown in the presence of both glucose and lactose are metabolizing lactose. In the test (b) and (c) will be responsible due to constitutive synthesis of lac operon will happen.
Proteins of smaller molecular size may be reabsorbed from the glomerular filtrate by the specific transport process of endocytosis.
<h3>What do you mean by Glomerular filtrate?</h3>
The Glomerular filtrate may be defined as the liquid in the lumen of the Bowman's capsule of the nephron that has been purified from the capillaries of the glomerulus.
The small molecular size proteins may be absorbed from the glomerular filtrate by receptor-mediated endocytosis. Then moved into the endosomes, and finally to the lysosomes for the degradation.
Therefore, proteins of smaller molecular size may be reabsorbed from the glomerular filtrate by the specific transport process of endocytosis.

Answer:
Parapatric speciation
Explanation:
There are different types of speciation. Parapatric speciation consists of new species evolving from a continuous distribution. That is, there is no physical barrier that might impede the gene flow, in fact, it might continue during the speciation process.
There is an environmental gradient that determines different phenotypes for different environmental conditions. One phenotype is more adapted to one of the distribution extremes than the other phenotype. In the exposed case, the environmental gradient is given by the differences in pH.
In the border between the environmental extremes, there is the primary hybrid zone, where both phenotypic forms might meet and hybridize.
