Aplant can have either broad leaves (b) or narrow leaves (b) a plant with genotype bb is crosses with a plant with genotype bb which punnet square correctly represents this cross

The correct answer is shown in the figure attached below.

The genotype of one parent is Bb. Thus, it would produce two types of gametes.  

One type of gamete will contain B and another type of gamete will contain b.

The genotype of another parent is bb. Thus, it will produce only one type of gamete which will contain b.

The cross would result in the production of offspring with two types of genotypes in equal proportions. The two genotypes would be Bb and bb.

The phenotypic ratio would be 1 (broad leaves): 1 (narrow leaves).

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.
