Answer:

Muscle cramps are caused by the inability of myosin fibers to break free from the actin filaments during contraction, resulting in a prolonged contraction. A lack of ATP would obviously produce cramping, as myosin requires ATP to become free from actin.

Which feature of viruses is the most similar to a feature of living things. Number 2
nikitadnepr [17]

Answer:

C

Explanation:

C is the most similar because unlike viruses, living things grow and develop, have a basic structure that IS based on cells, and don't require a host. So the only option here that is true for both living beings and viruses is that they both have a way to reproduce.

How should the hands of a caregiver be placed during an attempt to facilitate a muscle contraction?
Troyanec [42]
I think that the hands should be placed on top of the muscle that needs to be contracted. 

One of the exteroceptive stimulation techniques is MANUAL CONTACTS.

Under this technique, the hands will exert firm and deep pressure on the contact of the body where the muscle is located. This activates the <span>tactile or touch receptors and muscle proprioceptors. This also facilitates muscle contractions; muscles that are directly under the hands and provides support  and security to unstable body parts or segments.

Would the amount of cytosine and guanine be equal to each other in an RNA molecule?
allochka39001 [22]

Answer:

No

In RNA their arn't any base pairs but instead there are simply one base pairs, so any cytosine and  guanine molecule are not related to each other at all, and thereby they don't have to be the same amounts.

zysi [14]
<span>Answer: Correct1 Ask the client to tell the purpose of the PCA device. Correct2 Emphasize that client controls medication delivery. Correct3 Explain that the pump prevents the risk of overdose. 4 Tell family members to operate the PCA device for the client. 5 Teach the use of PCA after the client awakens from sedation. The nurse should teach the client about PCA and evaluate the client's understanding by asking the client to explain it back. The client should be the one controlling the administration of the medication based on the pain. It is programmed in a way to prevent overdose. The family members should not operate the PCA device for the client because the dose depends on the pain perception by the client. The client should be taught the use of the device before the procedures so that when the client awakens from sedation, the client can administer the analgesia.</span>
