Answer: The circulatory system and the respiratory system.

Explanation:

During gaseous exchange between tissues, the blood is an essential function of the circulatory system. In humans, lower mammals, and birds, blood absorbs oxygen and it inturn releases carbon dioxide in the lungs. Hence, the circulatory and respiratory system, work hand in hand.

olasank [31]

The right answer is: aorta to smaller systemic arteries to systemic capillaries to systemic veins to right atrium through the tricuspid valve.

The blood pathway is divided into two circuits, both beginning and ending in the heart.

- Systemic circulation (or general circulation, or "circulation")

It begins in the left ventricle, which through an artery distributes oxygenated blood to organs. Then the blood returns to the right heart (right atrium) through the cellar veins.

Each organ has an afferent vessel, supplying blood, and an efferent vessel carrying non-oxygenated blood.

- The pulmonary circulation (or "small circulation")

It begins in the right ventricle, from where the pulmonary artery sends blood without hematosis to a single organ, the lung. The blood is then oxygenated and returns to the left heart (left atrium) by the pulmonary veins.

A fruit fly of genotype B R/b r is testcrossed with b r/b r. In 84 percent of the meioses, there are no chiasmata between the li
Citrus2011 [14]

Answer:

4 percent (4%)

Explanation:

A single crossover occurs between two (non-sister) chromatids belonging to homologous chromosomes. In this case, 16 percent of the meioses have a single crossover, thereby it will produce 8 percent of the chromosomes with the original (parental) combination in the progeny and the remaining 8 percent should be recombinants. From this result, it is reasonable to conclude that half of these recombinants should be 'Br' (and the other remaining 4 percent should be recombinants 'bR'), and therefore the answer is 4 percent (4%).

Brrunno [24]
In the cross-section of a kidney, there are three main regions that become apparent. The outer region is called the "renal cortex", this is where the capillaries are mainly located. The deeper and darker region, that looks like small pyramids arranged in a semicircle is called the "renal medulla", where the filtering of the blood takes place. The flat, tube-like structure is called the "renal pelvis".
