In the blood most of the oxygen that will be used in cellular respiration is carried from the lungs to the body tissues in the blood most of the oxygen that will be used in cellular respiration is carried from the lungs to the body tissues as bicarbonate ions (hco3 -) combined with hemoglobin by the trachea water (h2o) dissolved in blood plasma

The correct answer is - combined with hemoglobin.

Explanation:

The oxygen that is inhaled by the organism to the lungs from the environment is taken from the lungs to the different body tissues through the blood for performing cellular respiration and get energy.

The blood contains hemoglobin which is an iron-containing metalloprotein that carries the oxygen in red blood cells of the blood to the different body tissues from the gills or lungs. This oxygen transport iron-containing protein present in almost all the vertebrates.

Thus, the correct answer is - combined with hemoglobin.

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

yes, because even though a theory has a  lot of evidence to support it, it is not always true
