Hypotonic, isotonic, hypertonic
these terms are connected to the solution concentration. hypotonic solution is the solution with low concentration (lower than the concentration of particles in the living cell of an organism). if you put a cell in such solution, that cell would baloon because of the water migrating inside willing to rebalance the concentrations. isotonic solution is the solution with concentration of particles equal to the concentration inside a cell. hypertonic solution has concentration of particles higher than a cell and putting cell in this solution makes it shrivelled because of the water flowing outside (willing to rebalance concentrations again).
that's a phenomenon of osmosis.
Which molecule is the primary energy currency of all cells ? Answer : ATP
The right answer is the lysosome
The lysosome is a eukaryotic cell organelle.
The lysosome contains hydrolases, enzymes intended for the degradation of intracellular molecules. They are only active at acidic pH, hence the lowering of the pH in the vesicle.
The lysosome has a cellular garbage function, where the non-functional or undesired molecules are removed by digestion.
B as asexual reproduction the offspring is genetically identical to the parent
The circulatory system moves the nutrients from the digestive system to all over the body.
