Answer:
contractile vacuole.
Explanation:
Contractile vacuole is an organelle which is damaged from the antibiotic and as a result the cell burst. The main function of contractile vacuole is to regulates the quantity of water inside the cell. If the contractile vacuole is damaged so it does not regulate water required by the cell as a result more water enters inside the cell which results in the bursting of the cell.
Answer: cell membrane
such as water, micro-organism
physical process
simple diffusion, osmosis and filtration
such as potasssium permaganate in water,urea a liver waste diffuses from the body and the kidney help in filtering it out
physiological processs
active transport, phagocytosis and pinocytosis
such as soduim-potassium pump, exocytosis
Explanation: transportation in and out of cell is done in different ways listed above but a barrier to this movement is the cell membrane which is an outer covering of the cell. it protect the cell and only some materials can penetrate the cell membrane e.g micro-organism, water e.t.c. the various physical and physiological processes are the various ways substance cna be liquid, solid or gas are transported within or outside the cell e.g food
Answer:
While creating the conservation strategy, there is a need to remember that humans are part of the ecosystem, and are not positioned over the top to govern the entire ecosystem. In this inter-associated system, all are dependent upon each other. Thus, safeguarding the solitary endangered species or looking after the entire ecosystem is equally essential.
Awareness amongst the public considering the importance of species diversity is required in order to encourage the conservation of all the species. Various ecologists focus more on the entire communities as one does not have complete understanding regarding this.
Answer:
These cells have specific types of receptors on their membranes.
