2 Describe the relationship between body mass and total surface area of the air sacs.

Explanation: The body mass is a weight of the person. The total surface area of the air sacs means that in an organism who is having air sacs, spaces are present in them In these air sacs there is a presence of air which is constant.

Explanation:

The relationships between the ratios of Hemoglobin total surface area of such conditions result from the available amount of air sacs that permits.

Birds of 21 species with body mass ranging from 8 to 170 g, in eight species of antiracial.

Air sacs are present as small sacs off the bigger respiration tubes (tracheae) of insects, as prolongation of the lungs in birds, and as final organs in the lungs of certain other vertebrates.

They give to increase respiratory efficiency by giving a huge superficial area for gas transportation.

this protocol provides a detailed procedure for total protein extraction for western blot analysis from achieved samples following trizol isolation of rna.

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
