1. the body’s cells require oxygen for cellular respiration. they must also rid themselves of carbon dioxide, a waste product. how does this explain the change in breathing rate? 2. the cardiovascular system moves blood around the body. blood carries oxygen to cells and removes carbon dioxide from them. how does this explain the change in heart rate? 3. what are some of the ways your body regulates body temperature during strenuous activity? 4. how did your body respond after you stopped exercising? a. what does this response tell you about your body’s ability to maintain homeostasis? use data from each of the 5 parameters to support your answer. 5. research the physiology of common cold and fever. predict the effect of common cold and fever on the five parameters.

burning of wood and coal

explanation:

the panel also concluded there's a better than 95 percent probability that human-produced greenhouse gases such as carbon dioxide, methane and nitrous oxide have caused much of the observed increase in earth's temperatures over the past 50 years.

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

a chain link fence because there so tiny even my albino donkey can't get out

that's all i luck!
