Answer:
Based on similar appearance - traditional
Based on evolutionary relationships- modern
Known as cladistics- modern
Known as Linnaean classification- traditional
Explanation:
Linnaeus was a Swedish Botanist who was the first to classify organisms based on the structural similarities which organisms had. This method of classification came to be known as the Linnaean classification. Organisms which had more closer resemblances in structures and features had more groups or taxa in common.
The modern system of classification depends on the evolutionary history of organisms. It determines which organisms are more closely and have common ancestors in the past.
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.

The correct answer is the second choice, "Two identical prokaryotic cells."
Binary fission happens when bacterial cells copy chromosomes and split into two. It's most common in prokaryotic cells, but can happen in some eukaryotic cells.
Answer:
ice age/ Quaternary glaciation
Explanation:
Ice ages have occurred in the earth history and do occur more or less regularly in a cycle. It is believed that ice ages are as a result of small changes in the earth's orbit and also dependent on the solar cycles. The temperatures on the earth reduce causing the ice sheets in the poles to extend to the subtropics.
The answer is heterozygous. It means that she has two different alleles for one specific gene. And homozygous means that it has two same alleles for one specific gene. Heterogenous/homogenous means the different or same between organisms.
