Which statement describes the ability of the cell membrane to allow various substance to move through it?

selective permeability

Explanation:

The cellular membrane is selectively permeable which means it allows the movement of little essential substance from outside and movement of non-essential substances from inside. Along with this several neural activities are controlled through this property of cell membrane that allows to and fro.  Movement of specific kind of ions.  

It does not allow movement of all substance, particles and ions through it and hence they are selective.

correct answer: understand the different control methods available

integrated pest management is an strategy that is based on the ecosystem and try to prevent the pest and the damage caused by them by applying combination of technique like habitat manipulation, biological control and use of resistant varieties.

the main aim of the integrated pest management is not to completely eliminate the pest but to strengthen the ecosystem so that conditions are favorable for plants and unfavorable for pests.

enzyme active site and substrate specificity

enzymes bind with chemical reactants called substrates. there may be one or more substrates for each type of enzyme, depending on the particular chemical reaction. in some reactions, a single-reactant substrate is broken down into multiple products
