Answer:
The hemolytic anemia is a disorder in which the destruction of the RBCs is faster than their production of the RBCs. Hemolysis is the term used for the destruction of the RBCs.
The body of an individual produces antibodies if it senses or there is an antigen that is foreign to the body that helps in the destruction or removal of the particular antigen with the help of antibodies or B cells.
Rh(D) antigen is foreign to the Rh-negative woman as her RBCs surface lack the D antigen so if RBCs expressed to mother blood, IgG production begins and travels to the fetus through the placenta and start destroying RBCs of the fetus. Hemolysis of fetus results in hemolytic anemia and some times death of the baby.
Answer:
a)Difference in physical state observed:
The difference between the two carrots is that the carrot in the plain water appears bigger or slightly swollen while the carrot in the salt water appears smaller and has shrank in length and slightly in width.
b)Process involved that has caused the changes:
The process that has taken place is osmosis.
c)Why has the process occured:
The process occurs due to the semi-permeable membrane of the cells of carrots that allow water either in or out of the cells.
In the plain water, the process that takes place is endosmosis where the cells of the carrot draw in water and hence the carrot increases in mass. The carrot in the salt water, on the other hand, experiences exosmosis, where water is drawn from the carrot's cells and the carrot becomes dehydrated and shrinks in length and width.
d) Beaker 1 : Water
Beaker 2 : Sugar Solution
e) example of endosmosis is absorption of capillary water from the soil by the root.
another example of endosmosis is is entrance of water in the xylem vessel from the soil by the root.
The step that will not occur would be oxidative phosphorylation, this requires oxygen to be the final electron acceptor.
Answer:
Mutations are one way for bacteria to become resistant to antibiotics. Some spontaneous mutations (or genes that have been acquired from other bacteria through horizontal gene transfer) may make the bacterium resistant to an antibiotic (See: Resistance mechanisms for information about how bacteria resist antibiotic action). If we were to treat the bacterial population with that specific antibiotic, only the resistant bacteria will be able to multiply; the antibiotic selects for them. These bacteria can now increase in numbers and the end result is a population of mainly resistant bacteria.
