H2 is a gas which forms when two hydrogen atoms bond together and become a hydrogen molecule. H2 is also called molecular hydrogen.It consists of two protons and two electrons. Consequently it is the most common form of Hydrogen because it is stable with a neutral charge. ... H2 is the smallest molecule in the universe.
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.

They need to cope with changing seasons and be able to withstand cold winters and hot summers
How are new alleles created? Occasionally, DNA mutations occur in germ cells – cells destined to become eggs or sperm. In this case, the DNA mutation is copied into every new cell of the growing embryo following fertilisation. ... If the mutation affects a gene, it will result in a new version of that gene – a new allele.
Answer:
The further the light moves from the plant, the fewer oxygen bubbles are produced by photosynthesis. The intensity of light at different distances from a light source can be described by the inverse square law.
