Which of the following occurs in the E site of the ribosome during translation? An uncharged tRNA is ejected from this site as the ribosome slides to the next codon.
Plant cell growth, an irreversible increase in cell volume, can occur by expansion (increase in cell size in two or three dimensions) or by elongation (expansion constrained to one dimension). Variety in cell shape may result if either of these two processes occur only at specific regions of the cell surface.
Sunlight help to provide energy to the plant to complete the process. Basically, the plant harvest the solar energy.
Answer: Contractile vacuole of amoeba will shrink/contract when the organism is placed in sea water.
Contractile vacuole is a subcellular structure ( mainly found in protists) that is involved in the regulation of water quantity inside a cell.
As we know that water always flow from a hypotonic ( where solute concentration is less) to a hypertonic ( where solute concentration is more) solution. Sea water is a hypertonic solution as the concentration of salt is very high. Therefore, in this case, water will flow from contractile vacuole to outside of the organism.
Thus, contractile vacuole of amoeba will contract as it will lose water when placed in sea water.
