A sarcomere is the basic contractile unit of muscle fiber. Each sarcomere is composed of two main protein filaments—actin and myosin—which are the active structures responsible for muscular contraction. The most popular model that describes muscular contraction is called the sliding filament theory.
Genus represents taxonomic rank above species and below family. When organisms belong to the same genus, they must be of the same phyla, but may be in different species. In binomial nomenclature it is the generic name shared by the group of close relative.
Answer:
The correct option is <em>C. Non-genetic factors can influence expression.</em>

In the above-mentioned scenario, both the monozygotic twins have diabetes but one of them is affected 70% of the time due to his lifestyle. The person might be consuming more sugars and alcohol.
Answer:
b.Movement of phospholipids in the plasma membrane from one monolayer to the other requires the polar or charged head groupd to enter the hydrophobic interior of the lipid bilayer. This process requires a large positive change in free-energy, thus making this type of movement unlikely without an input of energy
The plasma membrane serves a protective function for the cell and is a selective membrane for particles entry
