Antibiotics are of different spectrums of activity depending on the number of pathogens they can kill. They are different reasons for this differences in antibiotic specificity:
I. Antibiotics interrupt processes found in some but not all pathogen cells. For instance, some antibiotics are directed to cell walls that not all bacteria posses.
II. Some pathogens have no metabolic processes to interrupt. The antibiotics that are directed to metabolic reactions of bacteria are not effective in treating viruses because they do not perform this metabolic reactions.
III. Some pathogens have developed genetic resistance to specific antibiotics. Bacteria have a remarkable genetic plasticity having plasmids that can be easily transmitted among them, which give them antibiotic resistance.
Answer:
Of the trillions of cells that compose our body, from neurons that relay signals throughout the brain to immune cells that help defend our bodies from constant external assault, almost every one contains the same 3 billion DNA base pairs that make up the human genome – the entirety of our genetic material. It is remarkable that each of the over 200 cell types in the body interprets this identical information very differently in order to perform the functions necessary to keep us alive. This demonstrates that we need to look beyond the sequence of DNA itself in order to understand how an organism and its cells function.

Answer:
The stem cells differentiate into chondroblasts. 3. These chondroblasts, located at the periphery of the old cartilage, begin to produce and secrete new cartilage matrix. As a result, they push apart and become chondrocytes, each occupying its own lacuna.
Explanation:
Potential energy depends on molecular size and structures and is inherent properties of the molecules. Hope this help!!!
Answer:
Vacuoles are storage sacs used for storing liquid and solid contents.they are small in animal cells and large in plant cells.in plant cells vacuoles are full of cell sap and provide turgidity and rigidity to the cell.in single celled organisms like amoeba,the food vacuole contain the food item that amoeba has consumed.in some unicellular organisms specialised vacuoles also play important role in expelling excess water and some waste from the cell.
