Warm fronts
Not cold fronts because those move to warm
Answer:
No, not <em>all </em>organisms.
Explanation:
Hi there,
As you may continue to learn in biology, not all organisms go through the process of mitosis/meiosis. Well known examples are prokaryotes, such as bacteria and archaea, ancient organisms that replicate via binary fission, budding, and/or fragmenting
Mitosis and Meiosis only occur in eukaryotes and unique to them.
thanks,
Answer:
The correct answer will be option-C
Explanation:
The rhythm of the heartbeat is controlled by the pacemaker of the heart called the sino-atrial node.
The SA node generates action potentials which trigger the contraction and relaxation of the atrium and ventricles. The membrane potential generation initiates by the depolarization of the cell membrane when the L type of Ca⁺² ions opens up and calcium ions enter the cell.
This depolarizes the cell until the potential threshold is reached which lies between the -40 and -30 mV.
Thus, Option-C is the correct answer.
