Antibiotics are usually derived from bacteria.
Answer:
P wave
Explanation:
Electrocardiogram records the strength and timing of electrical activity in heart. As various regions of heart contract at different times and for different duration, the electrical activity is not constant and shows a series of rise and fall. There are three main components of ECG: P wave, QRS complex and T wave.
P wave indicates the beginning of electrical signal in the right atrium. The signal spreads in both right and left atria which leads to their contraction. As a result, blood is pumped into the ventricles and rest of the process occurs.

An </span>oxidation-reduction reaction<span> is any chemical </span>reaction<span> in which the </span>oxidation<span> number of a molecule, atom, or ion changes by gaining or losing an electron.</span>
1. The Ring of Fire, also referred to as the Circum-Pacific Belt, is a path along the Pacific Ocean characterized by active volcanoes and frequent earthquakes. The majority of Earth's volcanoes and earthquakes take place along the Ring of Fire.
2. Crustal recycling is a tectonic process by which surface material from the lithosphere is recycled into the mantle by subduction erosion or delamination
3. Tectonic plate movement can create another supercontinent like Pangea if the plates move continents to the point of meeting together.
