Answer:
B
Explanation:
The net movements of water from the region of higher water potential to the region of low water potential through a selectively permeable membrane is osmosis. It is a form of diffusion which involves the transport of water molecules.
In this present scenario water molecules pass through the selectively permeable membrane from higher water potential in the body, to lower water potential but high solute potential (Epsom salts). The later is called an hypertonic solution,this is because it has higher solute potential ,thus higher salt concentration than the surrounding medium,therefore water pass by osmosis into the Epsom salts.
If one is placed in this solution,the cells shrink as they lose water to the more concentrated Epsom.(hypertonic solution)
However, the body homeostatic mechanism through the kidney ensure re-absorption of fluid back to the body from the DCT and CT, via anti diuretic hormone to preserve the cell and the person.
Answer:
a fertilized egg- zygote
separation of two ends of an old cell- cytokinesis
union of egg and sperm- fertilization
egg-producing organ in lower plants- archegonium
Out of the following
given choices;
A. unimportant; no medical attention
B. stable; the R.I.C.E. formula
C. severe; immediate medical attention
D. severe; the R.I.C.E. formula
The answer is C. Head
injuries should never be overlooked. This is because
the brain could be damaged yet it is the most important organ of the body. Many
symptoms of serious brain injury won’t appear right away. Some injuries result
to internal hemorrhage that is not
detected then but later causes serious brain damage such as intracranial
hematoma.
