Explanation:
Answer:
The superior vena cava is formed by the merging of the right and left brachiocephalic veins.
Explanation:
The superior vena cava is one of the main veins of the human body, it is responsible for receiving blood from the head, neck, upper chest and upper limbs. It is formed by the union of the right and left brachiocephalic veins, they originate from the junction of the subclavian vein with the internal jugular vein to form the right and left brachiocephalic venous trunk, both trunks join or merge into a single trunk and they form the superior vena cava, which flows into the upper part of the right atrium.
Answer:
Option (B)
Explanation:
Chicago and Miami are both the cities in the United States, where Chicago is at a higher elevated area, whereas Miami is located in a low lying areas.
Chicago is located at an elevation of about 180 meter above the sea level, which is comparatively much higher than Miami, as Miami is at the coastal areas whose elevation is only about 2 meter above the sea level.
So, from the map it can be concluded that as Jessica travels from Chicago to Miami, it means that the elevation gradually decreases.
Thus, then correct answer is option (B).
The process of natural selection is described in the cartoon.
Explanation:
Natural selection is the mechanism by which an organism survive and evolve.
It is the process in which organism have better adaptation to its environment and live to reproduce organisms with useful traits which are passed on to their offsprings.
In the given cartoon it is observed that green beatles fall prey to the crows as a result their survival chances are minimal. Over the generations they are eaten by crows and eventually their brown counterparts are in majority. This is because the brown colour beatles are safe from the prey, they pass on this trait to their offspring and remains safe and more in population.
The brown colouration in beatles is the Darwinian trait of survival of the fittest for beatles.
The variation in population, mutation or genetic drift causes natural selection.
The one with better adaptation survives and reproduce more viable offspring in the population.
