The right matches are:
Ventricular fibrillation ==> Loss of consciousness and death
Two successive PVC's ==> Often asymptomatic
Bizarre ECG waves ==> Defibrillation is needed
.
Ventricular fibrillation is a violent and disordered contraction of muscle fibers, especially the heart muscle, in the ventricles. This systematically leads to loss of consciousness or death.
Defibrillation is a treatment by electrical shock of abnormal contractions of the heart fibers, in order to restore a normal heart rhythm.
Premature contraction of the heart alters the normal heart rhythm but is clinically undetectable or expressed as palpitations.
Involuntary muscles are the muscles that move without conscious control of the organism and are controlled by the autonomic nervous system.
Some examples of this are:
• the ,cardiac muscle, (,heart,)
,
• smooth muscles,, like the ones found in the ,stomach,, ,intestine,, and, bladder.
A non-living system would be a machine, such as an electrical system, air conditioning, etc. and a living system would be an animal, person, plant, etc.
<h3><u>Answer;</u></h3>
Carbohydrate
<h3><u>Explanation;</u></h3>
- Carbohydrate is the macromolecule produced during photosynthesis for plant food. Carbohydrate is among the four major macromolecules, others being, nucleic acid, lipids, and proteins.
- During photosynthesis energy from the sun, together with water and carbon dioxide are used to make nutrients or organic compounds such as simple sugars like glucose.
- By using the energy from the sunlight and absorbing the water molecules from the soil, the plant produces glucose molecules. The glucose is a carbohydrate.
