The image shows how oxygen and carbon dioxide are exchanged between human beings and the environment. which statement describes the image correctly? a) carbon dioxide is inhaled into the lungs. b) oxygen comes out of the capillaries of the lungs. c) oxygen is picked up by red blood cells in the lungs. d) carbon dioxide is absorbed by the blood cells in capillaries.

The correct answer is option C

The figure here represents that the oxygen is being taken up by the red blood cells in the lungs and will be transported to the whole body.

In return the carbon dioxide diffuse into the blood capillaries and is carried back to the lungs to get exchanged by oxygen.

This process of exchange of gas is called as respiration.

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
