Answer:

The correct answer is: Two of the statements above are correct.

A cardiac muscle cell contracts spontaneously and is joined to other cardiac muscle cells by structures called intercalated discs.

Explanation:

Cardiomyocytes, the only ones responsible for the contractile function of the myocardium, are terminally differentiated cells that cease to proliferate almost immediately after birth. Cardiomyocytes are mononucleated cells, with the nucleus in a central position. These are linked together by the so-called intercalary discs, which appear as dark bands in histological preparations, and which are a set of junction complexes where desmosomes and adherent junctions can be found (here called fascia adherens). The intercalary discs are therefore the boundaries between cells.

The scientific name of the sugar maple is Acer saccharum. What does each part of the name designate?
irinina [24]

Answer:Acer represents the genus name while

saccharum represents the species.

Explanation:

In a way to classify organisms, biologists used certain important common features to structure them into groups. The arrangement of living organisms in this hierarchy from the highest level to the lowest is as follows:

Kingdom--> phylum-->class-->order--> Family-->genus--> species.

The largest group of organisms is kingdom while species is the smallest unit of classification.

The common name of the plant used in the question above is sugar maple. Biologist, however, use a standard system to name living organisms. Each kind of organism is given two names, hence the term BINOMIAL NOMENCLATURE.

--> The first name is the name of the genus to which the organism belongs.

--> The second name is the name of the species to which it belongs.

Both names are printed in italics with only the genus name having an initial capital letter. Hence, the scientific name of sugar maple is Acer saccharum( in italics).
