Scientists use seismic waves from earthquakes to study the interior and the Earth's magnetic field. The seismic waves indicate the mantle is molten rock that flows like plastic, the outer core is completly molten rock, and the inner core is a solid ball of iron. The magnetic field indicates the inner core is spinning faster than the rest of the planet
The turtle's heart consists of three chambers, their atrium are completely divided while their ventricles are incompletely divided. The structure of the turtle's circulatory system allows the complete separation of oxygenated and deoxygenated blood. This makes the blood circulation of the turtle flexible.
Approximately 10% of energy is lost at each step of the food chain. Therefore larger predators must eat more to gain their energy requirements. For example if a Fox was third on the food chain it would only receive 1% of the energy the producer made
The Correct answer is "We want to understand the many aspects of human health, physiology, and behavior that are influenced by genes"
The geneticists devote so many resources to studying genetics in humans because they have realized that there are several diseases or physical traits (which may be due to the mutant gene) which are controlled by genes. For example diabetes which was earlier only thought to be regulated by insulin is now known to be as a heretical disease. Also it has been found that genetic diseases that are not present in the parent suddenly appear in their children. This may be due to the presence of recessive traits associated with genes and are being transferred from the forefathers. Not only diseases the physiological characteristics such as skin colour, eye colour, height, hair colour etc are also due to the result of expression of traits carried by the genes.
In the current scenario the different lifestyle, food and harmful environment conditions also produces genetic variation. Thus it is very important for the geneticist to refer several knowledge resources to understand the expression of gene under varying condition and how it may impact the humans.
The process in which water vapor turns into clouds is condensation.
