The study has implications for research in community ecology. Can you define some of the key terms in community ecology
Anestetic [448]

Some of the key terms in community ecology are Intraspecific Interaction, interspecific interaction, competitive exclusion, mutualism.

<h3>What is community ecology?</h3>
  • Community ecology aims to provide solutions to these and other community-related concerns.
  • An ecological community is a collection of organisms that coexist or may coexist in a given area. Communities are connected by a shared environment and a web of relationships between the many species.
  • An ever-expanding and comprehensive area of ecology is community ecology. Ecologists look at the variables that affect species distribution, community structure, and biodiversity. Interactions with the abiotic environment and the wide variety of interactions that take place between species are two examples of these elements.
  • The foundation of the majority of community ecology study is species interactions, such as competition, predation, herbivory, parasitism, and mutualism.

Penicillin-binding protein 2a, encoded by the medA gene, isn’t affected by beta-lactam antibiotics.
Flauer [41]

Answer:

The correct answer is - false.

Explanation:

Penicillin-binding protein 2a or PBPs are protein produced by bacteria that binds with the β-lactam antibiotics such as penicillin. They play role in the cell wall synthesis of bacteria by producing peptidoglycan by catalyzing the reaction.

β-Lactam antibiotics bind with the PBPs and cause the disruption to peptidoglycan cross-linking in the biosynthesis of the cell wall and ultimately lysis of bacteria takes place and cell death.
