The superior vena cava is located in the upper chest region and is formed by the joining of the brachiocephalic veins. These veins drain blood from the upper body regions including the head, neck, and chest. It is bordered by heart structures such as the aorta and pulmonary artery.
The superior vena cava (and inferior vena cava) are veins that return deoxygenated blood from circulation in the body and empty it into the right atrium.
The question is incomplete and the whole question is-
Interbreeding two different species of lovebirds produces offspring unable to build a nest after they mature because they lack the innate knowledge needed to carry the nesting materials. The hybrid offspring do not reproduce, and this limits genetic mixing of the two species. This is an example of:
Answer:
The correct answer is- Hybrid infertility
Explanation:
When members of two different species reproduce and produce offspring, then these offsprings are called hybrid. If the hybrid offsprings are not able to produce viable gamete and do not able to reproduce then this is called hybrid infertility. One of the famous examples is mule produce by breeding between donkey and horse.
So here interbreeding of two species of lovebirds produces offspring that do not reproduce and lack innate knowledge needed to build the nest which limits the genetic mixing between the species due to hybrid infertility.
Arteries carry blood away from the heart to the body.
