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.
Answer:
Pollination
Explanation: If you have ever seen bee movie, you know that pollen is the most essential ingredient to flowers, which is transported and spread by bee's. if there were no more bees, there would be no way to pollinate the flowers, causing them to wither and die. Fortunately, there are other pollinators, but bees are one of the most important.
Answer:
The correct answer is - cell wall made up of cellulose that makes it crunchy.
Explanation:
In plant-based foods, the outer membrane is a cell wall that provides structure and supports the plant to stand erect and protect from the outer environment. The cell wall is mainly composed of cellulose that is a carbohydrate which is comparatively crunchy or tough to the animal protein with a fatty cell membrane that makes it chewier than the crunchy.
The composition of the protective layers of the plant cels and animal cell causes this difference in their texture.
Sun and water mostly for a cycle of photosynthesis
