When a small populations' gene frequencies are changed drastically by chance alone it is called a genetic drift
Answer:
No answer.
Explanation:
Please provide more information or else we are unable to answer the question. (ex. What organisms?)
Two domains Archaea and Bacteria
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: Integrins
Explanation: Integrins are proteins and are the principal receptors that attach the cell cytoskeleton to the extracellular matrix (ECM). Integrins by sense whether adhesion has taken place that is to say a cell can regulate the adhesive activity of its integrins from within.
