The speed of a longitudinal wave will not be affected by the temperature of its surrounding. Base on the formula for the wave speed (applicable on longitudinal wave), wave speed ( speed in m.s 2) is equal to the distance of a wave (wavelenth in meter) travel over a unit of time (seconds) or wave speed is equal to distance of a wave times the frequency (hertz), temperature is not included in calculating the wave speed.
Answer:Genetic drift is the process where there are random fluctuations in the gene frequencies within a population. Which of these populations would most likely experience genetic drift?
Explanation:Genetic variation describes naturally occurring genetic differences among individuals of the same species. This variation permits flexibility and survival of a population in the face of changing environmental circumstances. Consequently, genetic variation is often considered an advantage, as it is a form of preparation for the unexpected. But how does genetic variation increase or decrease? And what effect do fluctuations in genetic variation have on populations over time?hen a population interbreeds, nonrandom mating can sometimes occur because one organism chooses to mate with another based on certain traits. In this case, individuals in the population make specific behavioral choices, and these choices shape the genetic combinations that appear in successive generations. When this happens, the mating patterns of that population are no longer random.
Nonrandom mating can occur in two forms, with different consequences. One form of nonrandom mating is inbreeding, which occurs when individuals with similar genotypes are more likely to mate with each other rather than with individuals with different genotypes. The second form of nonrandom mating is called outbreeding, wherein there is an increased probability that individuals with a particular genotype will mate with individuals of another particular genotype. Whereas inbreeding can lead to a reduction in genetic variation, outbreeding can lead to an increase.
When communicating to the healthcare provider, the nurse must report
pleural friction rubs during inspiration and expiration because this occurs when the
pleural layers or linings are inflamed due to loss of lubrication. The client
must be further assess for possible pulmonary infarction or pneumonia and the
nurse must recommend for a chest x-ray of the client to evaluate the condition.
This Is called deforestacion if to many trees are cut animals either have to adapt or find a new place if this doesnt happen the die
Answer:
A. Keratin
Explanation:
Keratin is the tough and fibrous intercellular protein. It is present in the skin cells and makes them resistant against microbes and chemicals. Most of the epidermal cells are keratinocytes that produce keratin protein. And the presence of keratin proteins makes the skin tough and protects it from chemicals of microbial origins.
