QRS complex refers to the combination of the Q, R, and S waves, and indicates ventricular depolarization and contraction (ventricular systole).
Ventricular rate can be calculated by determining the time interval between QRS complexes. The duration of the QRS complex is normally 0.06 to 0.10 seconds. This relatively short duration indicates that ventricular depolarization normally occurs very rapidly.
P QRS and T waves in electrocardiogram signifies the P wave in an ECG complex indicates atrial depolarization. The QRS is responsible for ventricular depolarization and the T wave is ventricular repolarization.

Answer:
C-G-A-G-T-C-C-G-C
Explanation:
The letters each have their own opposites. T is always the opposite of A. G is always the opposite if C
Answer:
Contraction.
Explanation:
Muscle tissues are defined as they are elastic and extensible in nature. In other words it's also defined as they are able to stretched and returned to its original size and shapes. A unique feature of muscle tissue is they are able of contractile in nature. With the help of this contraction they are able to sliding myosin and actin filaments which are present in muscles tissues.
Basically muscle tissues are three types:
1) Skeletal muscle: They are strong and rapid in contraction.
2) Cardiac muscle: They are strong in contraction.
3) Smooth muscle tissues: They are slow and weak in contraction.
Answer:
Lysosomes have the function of digesting substances, this function allows it to be involved in the removal of the interdigital membrane of the developing mammal fetus.
Explanation:
Lysosomes are organelles formed by numerous digestive enzymes. These enzymes allow lysosomes to be able to digest substances and even cellular apparatus, when needed.
The digestive function of lysosomes can be observed in the removal of the interdigital membrane of the developing mammalian fetus, by the action of digestive enzymes that have the ability to remove this entire membrane and any other undesirable tissue for the next stages of development of the fetus.
The cell theory consists of:
1. all living organisms are made up of cells
2. cells are the basic structural/organizational unit of all organisms
3. all cells come from pre-existing cells
