Answer:
Interphase is the basic phase of cell cycle.
Explanation:
Interphase is the non-dividing phase. It happens between two successive M phase. Interphase is preparatory phase during which the cell prepares for the next cell division and grows to the same size as their mother cell. This phase is further divided into three sub-phases: i) G1 phase- interval between mitosis. DNA replication begins here. It is the first growth phase, RNA and protein get synthesized. ii) S-phase- Synthesize of DNA takes place and chromosome gets duplicated. iii) G2 phase-
Pre-mitotic phase or the second growth phase. it prepares the cell for the next cell division.
The universe began about 14 billion years ago. Or 13.7 billion
it is the force with which a body is attracted toward Earth or another celestial body. This means that when you are in space, away from Earth, objects do not weight anything since they do not feel gravitational attraction to the Earth. Objects can have a large mass, but weigh nothing.
Answer:
The correct answer is " two cardiac muscle cells are connected by gap junctions".
Explanation:
Intercalated discs are microscopic features seen in the microscope as cardiac fibers, found between the myocardial cells of the heart. These features correspond of two cardiac muscle cells connected by gap junctions. The intercalated discs allow the interconnection of multiple cardiac cell muscles to work simultaneously as a single functional organ or syncytium.
