Oxygen and Carbon Dioxide exchange as a result of the interaction of which two body systems
1.Blood Cells and Respiratory System
2.Respiratory System and Digestion System
3.Circulatory System and Lungs
4.Circulatory System and Respiratory System

4

Explanation:

The circulatory system includes the blood that has picked up the carbon dioxide from all of the respiring tissues and who also delivered oxygen to them to continue respiring.

The blood will then reach the lung where the carbon dioxide that the tissues released is exchanged for oxygen in the alveoli.

* Blood cells isn't an organ system which makes 1 incorrect.

* Digestive system will in no way bring the blood to the lungs or away from it. This is the circulatory system's job. So 2 is incorrect.

*Lastly, lungs are organs and the question asks for organ systems. So 3 is incorrect.

the correct answer is - ability to find a mate

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
