Not sure but i think cohesion forces
Answer:
Autorhythmicity of the heart
Explanation:
It is the study of the characteristics features of the cardiac muscle cells with the ability to initiate action potential at certain level without connection to any external stimulus which the heart beats constantly and rhythmically. Cardiac muscle cells controls the rate of contraction of heartbeats.
Answer:
in the S phase of the cell cycle
Explanation:
<em>Scientists isolate cells in various phases of the cell cycle. They find a group of cells that have 1.5 times more DNA than G1 phase cells. The cells of this group are _____.</em>
The cell cycle has two main stages which is the interphase and the M phase.
While the M phase is characterized by active division, the interphase consists of G0 phase which is entirely a resting phase for cells that do not need to divide ordinarily, G1 phase which is a phase for cell drowth and development, S phase which is a phase for DNA synthesis or replication and G2 phase which is a phase for protein synthesis.
Hence, cells in the S phase and G2 phase of the cell cycle are expected to have more DNA than cells in the G0 and G1 phase.
<em>Essentially, the amount of DNA is doubled in the S phase. Therefore, if the cell group have 1.5 times more DNA than G1 phase cells, it means the cells are still in S phase.</em>
