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.
<h2>Active & Passive transport</h2>
Explanation:
- Active transport is where a chemical reaction using ATP moves things in/out of the cell through transport proteins within the cell wall. It uses a concentration gradient to trigger the reaction (it goes against the concentration gradient in active transport)
- Molecules move against a concentration gradient ( low concentration ―→ high concentration)
- Cellular energy (ATP) is required
- Passive transport also uses a concentration gradient by diffusion (hydrophobic or very small polar molecules) and facilitated diffusion via carrier proteins and channels
- Molecules move along the concentration gradient (high concentration ―→ low concentration)
- No cellular energy is required

Around the world the most significant restriction on access to potable water is money. While access to raw water sources, clean or otherwise, is important, the purification process itself is expensive.
