In a hemoglobin variant known as hemoglobin kansas, an asparaginein
the beta chain is replaced by a threonine. this results in
thedisruption of a hydrogen bond that normally stabilizes the
r-stateof hemoglobin. which statement is false regarding the effect
thisamino acid change has on the ability of hemoglobin kansas to
bindoxygen?
a. inhemoglobin kansas, there is an increase in the amount of
r-stateand a decrease in the amount of t-state.
b. in hemoglobinkansas, there is a decrease in the amount of
r-state and anincrease in the amount of t-state.
c. the r-state inhemoglobin kansas is less stable than
normal.
d. the presence ofless oxy-hb in hemoglobin kansas indicates this
type of hb has alower affinity for oxygen.
e. the p50 forhemoglobin kansas is higher than normal.

The false statement is option a.

Explanation:

If there occurs a disruption of a hydrogen bond, which usually stabilizes the R-state of hemoglobin, there is not likely to be an elevation in the concentration of R-state due to the unsteadiness of the hydrogen bond. The R-state would either remain constant or will get slow down.  

Thus, the statement, that is, in hemoglobin Kansas, there is an elevation in the concentration of R-state and a reduction in the concentration of T-state is false.  

ya the other dude is right

interphase

the period of cell growth when the cell synthesizes new molecules and organelles. the cell is not dividing and it constitutes the majority of the time spent in the cell cycle

prophase

changes occur in the nucleus and cytoplasm. the chromatin condenses to form structures (sister chromatids) visible with a light microscope and the mitotic spindle begins to form, but the nucleus is still in tact

prometaphase

the nuclear envelope fragments and the spindle microtubules attach to the kinetochores of the sister chromatids

metaphase

all the cell's duplicated chromosomes are lined up at an imaginary plane equidistant between the poles of the mitotic spindle

anaphase

begins when sister chromatids separate from each other and ending when a complete set of daughter chromosomes arrives at each of the two poles of the cell

telophase

the daughter nuclei form at the two poles of a cell

cytokinesis

the division of a cytoplasm to form two separate daughter cells. usually occurs during telophase during mitosis. this and mitosis make up to mitotic (m) phase of the cell cycle
