Incorporating basic life support, the first thing one should do is survey the scene. Look for any obstacles that will make the response difficult such as shattered glass, fire, etc. Second, call emergency hotline (usually it's 911 but it may differ from other countries). If you are a certified basic life support provider, then continue with the next steps. Next step would be checking the patient's airway, breathing, and circulation (ABC) by checking the if there is blocking the airway, or if the patient can breathe spontaneously, as well as the pulse. Next step would be assess if the patient as a cervical fracture as this should be handled carefully. If the patient is not breathing or has no/decreased pulse then proceed with doing CPR until help arrives.
Answer:
1. Green beetles and red beetles exist in the environment.
2. Birds that eat the beetles move into the environment.
3. Red beetles are eaten by birds, but green beetles aren’t eaten.
4. Green beetles pass on their color trait to future offspring.
5. The entire population of beetles eventually becomes green in color.
Explanation:
According to the theory of natural selection, only those species survives which fits closely with their environment. According to the conditions given, there are two genetic variations of the same species based on the color, i.e. green and red. Initially, both red and green are living together in a grassland (green in color). Then, birds enter the same environment because they have food there (beetles). Now, green beetles will take a competitive advantage because of the color and avoid getting eaten by the birds. However, red beetles would be prominent and eaten fast. The green beetles will pass on their genetic variation causing the color to be green in their future offspring and a time will come when there will be on green beetles in the area.
AC can be produced by using a device is called as an alternator. This device is a special type of electrical generator designed to produce alternating current. A loop of wire is rotated inside of a magnetic field, which induces a current along the wire.
Two causes of the ocean can be floods or tsunamis. Also technically hurricanes are a cause of the ocean as well as precipitation, such as thunderstorms or snow.
All organisms need energy to survive. It requires many units of lower trophic level organisms to feed the next trophic level. For example many first order consumers (fish) are required to feed one crocodile (top order consumer). This is because energy is lost as heat at each trophic level, so the energy available to the top feeding level is far lower than that of the producers (plants). This is what restricts the number of trophic levels in a food chain to four or five.
