Answer: choice c
Explanation: choice a and choice c are very similar, but the phrasing of the words is different. Genes are made up of DNA.
Answer:
An insertion mutation occurs when an extra nucleotide is added to the DNA strand during replication. This can happen when the replicating strand "slips," or wrinkles, which allows the extra nucleotide to be incorporated.
An electrocardiogram (ECG) provides information about B) the rhythm of heart contractions
The rhythm of heart contractions can be known by an electrocardiogram (ECG).
An ECG or Electrocardiogram is a method to diagnose the heart conditions to check the normal functioning of the heart.
The process to measure the electrical signals of the heart can be done by using this machine.
In this technique, three leads are attached to both the wrist and the left ankle to measure the electrical activity of Heart. The rhythm of the heart contraction and relaxation can be used to find out any heart abnormality.
It is used to investigate the heart problems associated due to bad health or some chronic inflammation affecting the functioning the body. Shortness of breath or nausea is investigated by using an ECG machine to help the patient and doctor to find out the cause.
It consists of QRS complex which measures the heart beat.

Answer:
Cross-bridges would form in the absence of an action potential from a motor neuron.
Explanation:
The injected calcium ions would bind to troponin. Troponin would make tropomyosin move away from the myosin-binding sites on actin. The presence of free binding sites on the actin would be followed by the contraction cycle. This would include hydrolysis of ATP to energize myosin heads and binding of these heads to actin to form cross-bridges. Therefore, cross-bridge formation would occur without any action potential if calcium ions are injected directly into the muscle.
