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:
Food chain is an excellent example of the first law of thermodynamics.
Explanation:
First law of thermodynamics states that energy of the universe is constant. It is always found in the universe in some form or the other. It cannot be destroyed or totally used up and we cannot also create energy out of anything in this world. Energy transforms from one form to another form.
Food chain is considered to be an excellent example of 1st law of thermodynamics. Every living organisms in the world posses energy. And all living organisms consumed each other or eat each other for their survival and consumes these energy to survive. So the energy possessed in one organisms or animal is transferred to the other organism that is higher in the food chain when they eats the lower organisms or animal in the food chain.
Thus energy transfers form one form to another.
Cancer cells do not have the DNA program to stop replicating new cells the way normal cells do. This causes them to rapidly reproduce causing tumors.
They are antiparallel. One strand goes 5'-3' and the other goes 3'-5'
Answer:
The correct answer will be option-E
Explanation:
The structure of DNA revealed by Watson and Crick showed that Two strands of DNA are present in the intertwined state forming helix representing DNA as a double helix.
Each strand of DNA is made up of the monomer unit of DNA called nucleotide where each nucleotide binds to another nucleotide through weak covalent bond called phosphodiester bond.
The phosphodiester bond is formed between the 3’-OH group of one nucleotide to 5’ phosphate group of another nucleotide. In this way, the phosphate-sugar molecule forms the backbone of the DNA molecule.
Thus, option-E is the correct answer
