Well lava isn't just plain liquid for instance water runs through a stream fast but lava contains rocks and other materials so it runs slowly
Insect immunity doesn't include the property of an enzyme activation of pathogen-killing chemicals.
What is enzyme activation of pathogen?
Due to various trehalose's importance in pathogenic organisms, there has lately been a surge of interest in trehalose metabolism for therapeutic applications.
- TPP (trehalose-6-phosphate phosphatase) is an important enzyme in the most important biosynthetic pathway (OtsAB).
- The enzyme properties of recombinant TPPs from five key nematode and bacterial pathogens, including three new members of this protein family, are compared here.
- The kinetics of trehalose-6-phosphate hydrolysis demonstrate that all five enzymes exhibit burst-like kinetic behaviour, defined by a drop in enzymatic rate beyond the pre-steady state.
- Multiple global conformational changes in members of this enzyme family during substrate processing can explain the observed super-stoichiometric burst amplitudes.
Hence, the correct answer is option A

Answer:
An operon consists of a group of genes which are controlled by a single promoter.
The lac operon present in the E.coli comprises of genes for making proteins which breakdown lactose into glucose.
Normally, the lac operon will be turned of by a repressor when there is not enough lactose present.
When lactose is present in the cell, the operon is activated when lacl forms a bond with the promoter region due to its changes in the structure. This causes the process of transcription to occur.
