The correct answer is: behavioral isolation.
Behavioral isolation is a form of reproductive isolation (prevention of interbreeding in closely related but not the same species) based on behavior such as rituals and signals-song of birds. This means that two species of birds, Eastern and western meadowlarks
are capable for breeding but don't breed because of differences in their breeding calls-songs.

Many prokaryotes are adapted to live inside the body because the majority of bacteria are mesophilic.
Depending on the optimal temperature of development, there are three types of bacteria:
* Mesophilic bacteria prefer average temperatures between 20 and 40 ° C. The majority of bacteria is mesophilic. This is the case of pathogenic bacteria of man and animals, but also commensal bacteria of natural cavities, cutaneo-mucous membranes and especially saprophytic environmental bacteria involved in the degradation and recycling of dead organic matter. (necromass).
* The psychrophilic bacteria have an optimal temperature of development close to 0 ° C.
* Thermophilic bacteria can live at high temperatures (45 ° C in hot springs).
Answer:
d. The normal bonding between the R groups has been disturbed and the protein loses its normal shape.
Explanation:
Denaturation is the loss of function of a protein due to its altered three-dimensional structure. To function properly, proteins must be present in a properly folded form. The three-dimensional structure and protein folding are mediated by weak interactions such as hydrogen bonds, electrostatic interactions, etc. An abrupt increase in temperature, pH or presence of some organic solvents causes protein denaturation.
The organic solvents target the hydrophobic interactions between the R groups of amino acids that make the core of globular protein stable. Extreme levels of pH target the net charge on proteins and thereby results in electrostatic repulsion between closely placed amino acids. Extremes of pH also disrupt the hydrogen bonding between the R groups of the amino acids. The effect is the loss of the three-dimensional structure of proteins, their partial or complete unfolding and loss of function.
A muscle is wrapped in epimysium and the muscle is composed of several fasicles, which is a fancy word for multiple muscle fibers wrapped in perimysium.
