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:
because 90% of energy is lost in the environment as heat.
Explanation:
According to the 10% rule, only 10% of energy is transferred from one trophic level to the next trophic level. It means that if the producers have 100% percent energy than only 10% of energy will be passed from producers to primary consumers.
So only a small amount of energy is transferred to the next trophic level because most of the energy is lost as heat during the oxidation of food. Therefore a very small amount of energy is transferred to the highest trophic level.
As less energy is available to support the organisms present on higher trophic level so their number is lower than the number of organisms present at lower trophic levels.
