Answer:
the correct option is D.
Explanation:
in case of quaternary level of protein structure , protein has more than one polypeptide chains and in this level , the polypeptide chains are aggregated and held together by hydrophobic interactions, hydrogen and ionic bonds. this specific arrangement is called the quaternary structure.for example :-
Haemoglobin the oxygen carrying protein of red blood cells, exhibits such a structure.
Answer:
ATP (Adenosine triphosphate)
Explanation:
ATP that is also known as energy currency of the cell is the principal compound which living organisms use to release and store chemical energy. This is because the structure of this molecule which has the ability to store and release enormous amount of energy.
As you can see in the structure of ATP molecule, it consists of one sugar unit ribose, bonded with an adenosie unit at one side and three phosphate atoms at the other side. The phosphate bonds hold tremendous importance for making ATP an energy currency.
The process of release of energy involve the breakdown of phosphate bonds from ATP molecule and is known as hydolysis. The first phosphate bond breakage produces 7 kcal/mole amount of energy while the other ones produce relatively lesser amount of energy as depicted in figure.
When the cell needs energy to perform its activities one phosphate bond is broken from ATP releasing energy stored in the bond that the cell can use to do work and converts ATP to ADP (Adenosine di phosphate).
When cell needs to store energy a phosphate bond is added with ADP and energy is again stored. This is a part of the process of cellular respiration that is key process of producing energy.

- Review data to identify the causes of early or delayed drug administration
- Revise the list of time-critical drugs as appropriate
- Make system-based changes to facilitate timely order review, dispensing, and administration of time-critical medications
- Follow the Rights of Medical Administration
Explanation:
Rights of Medical Administration
1. Right patient
- Check the name of the patient.
- Check the date of birth of the patient.
- Check two basic identifiers for the patients.
2. Right medication
- Check the medication label and reassure that it is the best for the patient.
3. Right dose
- Check that the dose is right for the age, size, and condition of the patient.
- Different dosages may be indicated for different conditions.
- Confirm appropriateness of the dose.
- Calculate the dosage correctly.
4. Right route
- Check and confirm that the route is appropriate for the patient’s current condition
5. Right time
- Check the frequency of the medication.
- Double-check the dose if given at the right time.
- Confirm when the last dose was given.
6. Right documentation
- Document administration after giving the medication.
- Note down the time, route, and other information required.
7. Right reason
- Check patient’s history for the ordered medication.
- Check the reasons for long-term medication use.
8. Right response
- Check the desired effect.
- Document monitoring of the patient and any other nursing interventions applicable.
Answer:
I believe the correct answer is B) Cells contain DNA, which is made up of genes that contain the instructions to make proteins.
Explanation:
This is because DNA stores information on how to make proteins. This information is stored in chromosomes, which are located in your cells. Chromosomes are made up of smaller segments of DNA, called genes. Each gene contains directions on how to go about making different types of proteins.
So, basically:
Cells → Chromosomes → DNA → Genes → Proteins
