Answer:
Thermosensitive liposomes (TSL) are promising tools used to deliver drugs to targeted region when local hyperthermia is applied (∼40–42°C) which triggers the membrane phase transformation from a solid gel-like state to a highly permeable liquid state. Selective lipid components have been used to in TSL formulations to increase plasma stability before hyperthermia and speed drug release rate after. Two generations of TSL technology have been developed. The traditional thermal sensitive liposomes (TTSL) have utilized DPPC and DSPC as a combination. The second generation, lysolipid thermally sensitive liposomes (LTSL) technology, has been developed with incorporation of lysolipids that form stabilized defects at phase transition temperature. LTSL maintains certain favorable attributes:
High percentage of lysolipids incorporation;
Minimum leakage for therapeutical drugs encapsulation;
Ultrafast drug release upon heating (3.5 times enhanced compared to TTSL). For example, ThermoDox, a commonly used LTSL drug for cancer, has been reported to release 100% of the encapsulated doxorubicin within 30s;
First and most successful formulation for intravascular drug release.

Answer:
The amount of water given to the plants depends on the effect of how tall the plant can overall grow. For instance, if all twenty identical plants are being given the same amount of water, then they will grow all at equal rates. However, if there is not equal amount/consistency with the amount of water the plants receive, then this factor may contribute to an uneven growth pattern between all twenty plants. However, other factors (such as location, sunlight, etc.) may also contribute to a plant's growth.

Answer:
The eukaryotic cell is 10 to 100 times larger than the prokaryotic cells.
Explanation:
The eukaryotic cell is 10 to 100 times larger than the prokaryotic cells. The prokaryotic cells are primitive, simpler in structure. The eukaryotic cells are complex in structure and have different adaptation for various cellular activities.
All the cells have cytoplasm, cell membrane, nucleus. In prokaryotes, the nucleus is not well defined and no other membrane-bound organelles.
e.g. bacteria, archaea.
The diameter of prokaryotic cells is smaller than the eukaryotic cells. Because the transport of ions and cell division is faster in it. Its diameter ranges from 0.1 micrometers to 5.0 micrometers. While eukaryotic cell diameter is 10 to 100 micrometers.
The small size of the prokaryotes is an advantage to its cellular processes whereas the eukaryotic cells are larger. Because it has to adapt to the function of different cell organelles present in it.
