Answer:
Crossing over
Explanation:
This exchange of genetic material is called chromosomal crossover, or crossing over.
Answer:
Extrinsic regulatory mechanisms are external and depend on the firing of some factor outside the population itself. Among them are interspecific competition, food and space restrictions, very strong climatic variations, weathering and inharmonious relationships with other populations (parasitism and predatism).
Good examples of interspecific competition appear when rabbits, caves, rats compete for the same plant, or different fish and birds, such as the heron, vie for the same species of smaller fish. This is because these different species keep their populations in the same ecological niche. Competition is often so strong that some species eventually, as one example of an extrinsic homeostatic mechanism overriding an intrinsic homeostatic process is their disappearance or migration to other regions.
In this competition, the presence of adaptations among individuals in the population that promote better food search, speed, vision, and others can make the difference between elimination and survival.
In general, pseudoscience is based on "<span>static information that does not change" because this kind of fake science doesn't change when new evidence is brought into light. </span>
In the given case, no antibiotic is needed for dental procedures.
Based on the updated recommendations from the American Heart Association, there is no need to take a precautionary antibiotic prior to dental proceedings for the majority of people.
It has been suggested by AHA that only those who are at greatest threat of bad consequences from infective endocarditis needs to get the short-term preventive antibiotics prior to routine dental approaches.
It has been recommended by the AHA guidelines that various of the people who have taken preventive antibiotics in the past no longer need them, these include the individuals with the conditions, like mitral valve prolapse, ventricular septal defect, bicuspid valve disease, rheumatic heart disease, and others.
