The plasma membrane of skeletal muscles, which can conduct electrical signals, is also known by the term "sarcolemma."
The plasma membrane of skeletal muscles is also known as the sarcolemma. The sarcolemma is a specialized plasma membrane that covers the muscle fibers (cells) and allows for the conduction of electrical impulses, which is necessary for muscle contraction. The sarcolemma is composed of a phospholipid bilayer, which separates the interior of the cell from the extracellular fluid.
Embedded within the sarcolemma are a variety of proteins, including ion channels, receptors, and transporters, which allow the muscle cell to interact with its environment and carry out its functions.
Overall, the sarcolemma is a critical component of skeletal muscle function, allowing for the efficient transmission of electrical signals that drive muscle contraction.

definiion of relativer contribution that an individuals makes to the gene pool
The relative contribution that an individual makes to the gene pool refers to the proportion of genes that they pass on to their offspring compared to the genes passed on by other individuals in the population.
This concept is important in evolutionary biology because it helps to determine which traits are more likely to become more prevalent in future generations.
The relative contribution of an individual's genes can be affected by factors such as their reproductive success, the number of offspring they have, and the genetic diversity of the population.
In general, individuals with traits that enhance their reproductive success are more likely to make a greater relative contribution to the gene pool.
