The external cell membrane. Even organisms as simple as bacteria have a cell membrane.
Prokaryotes do not have internal membranes but they still have external membranes.
Everything living thing has a cell membrane
The correct answer is option B
Sperm cells when pollinated by the insect to the female body part stay there for a while til the part of the flower determines its suitability and once it is done the sperm travels down through the pollen tube.
Answer: The correct answer is B) Superconductor, conductor, semiconductor, insulator.
Resistivity to the flow of electrons is inversely related to the conductivity of the material. This means that more is the resistivity, lesser is the conductivity.
Superconductors are those materials, which have zero resistivity. Thus, they have maximum conductivity, conductors are those that have little resistivity, semiconductors have more resistivity than conductors, and insulators have maximum resistivity so they do not allow the electric current to pass through them.
Thus, B) is the right answer.
<span>The treatments for fractures are pretty common to include plenty of bed rest. Using cold compresses very frequently, taking any prescribed or over the counter nonsteroidal drugs for pain relief as needed. As the area starts to heal start to do either home based or physician recommended physical therapy to get the fracture up to par.</span>
The statement that describes the cell after twenty minutes is this: WATER WILL MOVE FROM THE CELL INTO THE BEAKER RESULTING IN A SMALLER CELL.
Osmosis is defined as the process by which the molecules of a solvent move through a semi permeable membrane from the region of lower concentration to the region of higher concentration. For the question given above, the concentration of 30% salt is greater than that of 10% in the cell, so the water molecules will move from the cell [region of lower concentration] into the salt solution [region of higher concentration]. The loss of water will make the cell to shrink and to become smaller.
