Birds require high levels of oxygen and, therefore, high rates of gas exchange due to flight demands. Avian resting oxygen consumption is high compared to that of mammals and other vertebrates, and this increases even more during the flight.

Explanation:

Compared to mammals, birds have specific adaptations of the respiratory system that result in higher levels of oxygen exchange.

The light micrograph shows dividing cells near the tip of an onion root. Identify a cell in each of the following stages: propha

ad-work [718]

Mitotic division in onion root cells:

Prophase: the emergence of chromatin threads that form chromosomes, the chromosomes are visible and overlap.
Metaphase: chromosomes line up and line up in the middle of the equatorial plane. The centromere of the chromosome appears to have bonds with the kinetochores connected to the spindle threads.
Anaphase: the centromere of the chromosome undergoes division then the chromosomes are pulled by the spindle threads towards the two opposite poles and leave the center of the equator that looks empty.
Telophase: The cytoplasm divides into two identical-looking daughter cells. At the telophase stage, the process of cell division occurs in two parts and has identical properties.

Mitosis is a cell division through the stages of prophase, metaphase, anaphase, and telophase. The purpose of mitosis is for growth and regeneration which results in two daughter cells that are identical to the original parent cell. Mitosis occurs only once and lasts only during somatization.
