Answer:
Cats also purr when they are nervous or in pain, leading some experts to believe that this uniquely feline vocalization is actually a method of self-healing. A domestic cat's purr has a frequency of between 25 and 150 Hertz, which happens to be the frequency at which muscles and bones best grow and repair themselves.
Explanation:
Penicillins disrupts bacterial cell wall synthesis.
<h3>
How does penicillin affect bacterial cell walls?</h3>
- Penicillin kills bacteria by inhibiting the proteins which cross-link peptidoglycans in the cell wall .
- When a bacterium divides in the presence of penicillin, it cannot fill in the “holes” left in its cell wall.
- β-Lactam antibiotics, including penicillins, cephalosporins, monobactams, and carbapenems, are distinguished by a lactam ring in their molecular structure and act by inhibiting the synthesis of the peptidoglycan layer of bacterial cell walls.
- Penicillins work by bursting the cell wall of bacteria. Drugs in the penicillin class work by indirectly bursting bacterial cell walls.
- They do this by acting directly on peptidoglycans, which play an essential structural role in bacterial cells.

The correct answer is C. Trophic level
Explanation:
In biology, a food chain refers to a network that describes the relationship between the organisms in terms of food or the way organisms eat other and can be eaten. Because of this food chain are organized according to different levels that include producer organisms such as plants, herbivore animals such as rabbits, predators that eat other animals such as eagles and decomposers such as certain worms or bacteria. Each of these levels is known as a trophic level and describe the position of each type of organism in the food chain. Additionally, food chain guarantees balance in the ecosystems as it controls the population of species. Thus, the position in the food chain refers to a trophic level.
