Disruption in the intercalated discs in the cardiac muscles would interfere with the hearts ability to beat in synchronous manner.
The important salient features of intercalated disc are-
- These intercalated disc in cardiac muscles of the heart create connections between nearby cells
- The intercalated disc provides for coordinated operation of the cardiac cells and is highly specialised to facilitate the beating
- Extensive folds and intercellular junctions for mechanical and electrical interactions between neighbouring cells make up the intercalated disc at the ends of muscle cells
The electrical characteristics of the cardiac muscle cells and the passage of electrical information from one region of the heart to another determine the rate at which the heart contracts and the synchronisation of atrial and ventricular contraction necessary for the efficient pumping of blood.

TRUE-
Earth's
geochemical and biogeochemical cycles are important because they tend
to maintain a balance of Earth's materials. true or false ?
Answer:
Weathering is the breaking down of rocks, soils, and minerals as well as wood and artificial materials through contact with the Earth's atmosphere, water, and biological organisms. Weathering occurs in situ (i.e., on site, without displacement), that is, in the same place, with little or no movement, and thus should not be confused with erosion, which involves the transport of rocks and minerals by agents such as water, ice, snow, wind, waves and gravity and then being transported and deposited in other locations.

Answer:
The living organisms in an ecosystem can be divided into three categories: producers, consumers and decomposers. They are all important parts of an ecosystem. Producers are the green plants. They make their own food.
