Explanation:

In the given question two traits being studied, the traits are flower color and seed shape.

This is a typical Mendel’s dihybrid cross. According to the question purple colour (P) and round seed (R) are dominant traits.

When heterozygous purple-flowered (Pp), round-seeded (Rr) individuals are crossed, four different types of plants are produced phenotypically in the ratio 9:3:3:1.Out of 16 offspring, 9 are purple flowered, round seeded pea plants, 3 pea plants are white-flower with round seed, 3 are purple- flower with wrinkled seed and 1 pea plant is white-flowered with wrinkled seed pea plant is produced.

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.
