When performing Cardiopulmonary Resuscitation or CPR you have to follow the following steps:
1. Make sure that the scene or environment is safe.
2.Tap the patient and ask if he/she is okay, if the victim is non-responsive proceed to CPR.
3. First, perform the head-tilt chin-lift maneuver to open the airway.
4. Start by giving 30 chest compressions and 2 breaths thereafter. Watch for response from the patient and if there is none, repeat the cycle.
Therefore, when performing rescue breathing, tilt the head of the patient.
Answer:
C. mRNA
Explanation:
Hello,
In this case, we may remember that when DNA is undergoing transcription a specific sequence is copied via the RNA polymerase in order to produce the messenger RNA which is subsequently used as the starting material of translation for the protein synthesis as shown on the attached picture. Thereby, answer is C. mRNA, since the transcription process produces it and then, for the translation process, it contains the codons which promote the formation of polypeptides (proteins) via the connection of the anti-codons contained in the tRNA which also provide the amino acids for the polypeptides formation.
Regards.
Answer and Explanation:
To determine the overall health of the alligator pond, Mr. Ortiz should carry out the following tests:
pH is extremely important in this type of research as a reduction of pH could lead to a higher availability of toxic metals that may be absorbed by aquatic organisms such as alligators and fish species.
<em>pH is acceptable in a range of 6.5 to 8.2.</em>
- <u>Nitrates and Ammonia (NH3) levels</u>
Oversaturation of nitrates and ammonia could lead to the death of organisms that are crucial for the maintainance of a healthy pond and for the balance of the food chain.
Moreover, it could lead to algal blooms that result in a lower concentration of oxygen available for other organisms.
<em>Over 0.2 per L could be lethal</em> to some fish species that are also important for the health of the alligator pond.
<em>Less than 0.1 </em>indicates a healthy alligator pond.
- <u>Bacterial coliform test</u>
This test determines the amount of bacteria that comes from waste (animal or human), which could lead to mild to serious bacterial infections and diseases.
If it is a healthy pond, the results should indicate <em>less than 10 fecal coliform bacteria/100 mL.</em>
Answer:
Living organisms that are heterotrophic include all animals and fungi, some bacteria and protists, and many parasitic plants. The term heterotroph arose in microbiology in 1946 as part of a classification of microorganisms based on their type of nutrition.
