This process is active transport.
Unlike other methods such as diffusion or osmosis, active transport requires extra energy provided by the organism from such as cellular respiration. In addition, they also require a carrier protein, which can change its shape to bring the substance through the cell membrane.
Some examples requiring active transport may include root hair cells absorbing mineral ions, or our small intestine absorbing digested nutrients into our body.
Answer:
Option (1).
Explanation:
Dual x-ray absorptiometry technique is used for the evaluation of the bone mineral density. The bone densitometry is normally used in this technique to estimate the mineral content of bone.
The radiation dose in the absorptiometry is considerable and only small or low amount of radiation dose is considered. The heavy dose may cause health problems in the individual. The photon energies are used for the bone and soft tissue. The treatment of osteoporesis can be done by this technique.
Thus, the correct answer is option (1).
According to FDA prescribing
information, each 2 mL of Solu-Medrol (when mixed as directed) contains methylprednisolone
sodium succinate equivalent to 125 mg methylprednisolone. Therefore the nurse
will administer 2mL of Solu-Medrol every 8 hours in lieu of 125 mg of methylprednisolone.
Its Option 1 : The earth magnetic field is primarily a dipole that is ithas two poles. This brings the North and south magnetic pole.
