PLEASE SOMEONE AWNSER THIS FOR REALLLL PLEASEEEEE
ziro4ka [17]

Answer:

It is pertinent to understand what hypertonic, hypotonic, and isotonic solution means before setting out to explain how a cell reaches equilibrium in each type of solution.

A hypertonic solution is one whose solute concentration is higher than that of the sap of a cell that is immersed in it.

A hypotonic solution is one with the same solute concentration as that of the sap of the cell immersed in it.

An isotonic solution has a lower solute concentration than that of the sap of the cell immersed in it.

In biological systems, water molecules move by osmosis from the region of higher water potential or lower concentration of solutes to the region of lower water potential or higher concentration of solute. An equilibrium is reached when there is no net movement of water between two sides. Hence;

A cell placed in a hypertonic solution will lose water to the surrounding solution until an equilibrium is reached. This means that such a cell will end up shrinking (wilting) or even dying due to loss of water from the cell sap.

A cell placed in a hypotonic solution will gain water from the surrounding solution until there is no net movement of water anymore. Such a cell might become turgid or even burst out its cell content.

A cell placed in an isotonic solution will neither gain nor lose water because the cell sap and the surrounding solution have equal solute concentrations.

List the 6 possible genotypes of the four blood types. Identify the parentalgenotypes that could produce children with blood typ
ziro4ka [17]

Answer:

The different possible genotypes are AA, AO, BB, BO, AB, and OO. These are derived according to the A, B and O blood group model.

The table is given below:

Blood Type Genotype

Blood Type A Genotypes AA or AO

Blood Type B Genotypes BB or BO

Blood Type AB Genotype AB

Blood Type O Genotype OO

The alleles A and B exhibit a greater dominance than O. This is the reason why the Parent of Blood type A will form the Genotype AO.
