Answer:
Genus
Explanation:
In the scientific name "Panthera tigris", Panthera is the name of the genus and the "tigris" is the name of the species. Similarly in the name "Panthera leo", the name "Panthera" denotes the genus while "leo" is the species. This means that the tiger and lion belong to the same genus. They both belong to the genus "Panthera".
Though the species of the tiger is "tigris" and that of the lion is "leo". Both are the species of the same genus since the genus includes closely related species. The members of these different species can not interbreed but share some common features as they belong to the same genus.
Answer:
The correct answer will be- Transverse tubules
Explanation:
Transverse tubules are the tubular structure formed by the extension of the plasma membrane which innervates the cardiac and skeletal muscle cells. The T-tubules structure is structured between 20-40 nm and located at the junction of the I and A band.
The signals from the motor neurons once raches the motor endplate in muscles are carried into the muscles by these T-tubules which transmits the signals to muscle cells at very high speed. The T-tubules cause the release of the Calcium ions from the sarcoplasmic reticulum that cause contraction of the skeletal muscle.
Thus, Transverse tubules are the correct answer.
Explanation:
1. Barr body is a drumstick-like structure of dense, coiled chromatin that appears normally in female's buccal cells and neutrophils. It represents the inactive X-chromosome (Females have two X-chromosomes. Only one is active.)
2. Liver cells are somatic, not sex cells and are thus diploid.
