The elastic artery absorb most of the shock when the heart ejects blood. The expansion stores energy; the recoil disperses this energy by moving blood further through the circulation.
Answer: Option (D) is the correct answer.
Explanation:
Non-metals are electron deficient in nature so, in order to complete their octet they need to gain electrons from metals or electron rich atoms.
Whereas metals are electron rich in nature so, in order to gain stability metals lose their valence electrons.
For example, atomic number of potassium is 19 and its electronic distribution is 2, 8, 8, 1. Whereas atomic number of chlorine is 17 and its electronic distribution is 2, 8, 7.
Therefore, sodium in order to gain stability will lose its valence electron to chlorine atom. Hence, an ionic bond will be formed resulting in the formation of KCl.
Thus, we can conclude that non-metals seek to gain electrons to have full outermost shells, while metals seek to lose electrons to have full outermost shells.

Answer:
E. Weather radio collars are the only practical means that park rangers have for tracking the movement of the rhinoceros in the park.
Explanation:
E. Weather radio collars are the only practical means that park rangers have for tracking the movement of the rhinoceros in the park.
Nowadays there is a lot of technology available for tracking and monitoring of wildlife in big areas. If these radio collars are falling off very frequently and the tranquilizer is being used a lot, it means the method they are using is not the best or very efficient for this type of big animals.
They can use for example GPS trackers in a microchip implanted below the rhinoceroses skin or <u>even inside the horn</u>. With this process the park rangers would just need to use the tranquilizer once to immobilize the animal for a little bit, implant the GPS tracker or microchip; <u>this device won't fall or slip off and won't do </u><u>any harm</u><u> to the rhinos either</u>. This procedure will reduce the risk of the collar falling off and the use of the tranquilizer every time it does fall. Additionally, with this trackers, the park rangers, supervisor or vet can access the information <u>24 hours a day, in real-time</u> from a computer or even an electronic device. This new technology even offers an alarm systems by SMS or calls every time an abnormal rhino activity is detected.
Answer:
The answer to this question is energy.
Explanation:
All the natural processes taking place on this Universe requires Energy. We have energy stored in different forms in all objects on earth. Like chemical energy is responsible for different chemical reactions for example the formation of ATP in living organisms. Thermal energy that is present in the form heat and Kinetic energy is present in moving objects. Energy can not be created or destroyed. However it can be change from one form to another. That's how all the processes on earth keep going.
