The process of continued divergence in this scenario is called reinforcement.
Natural selection works to prevent hybridization between divergent populations through a process known as reinforcement, which leads to the emergence of interbreeding barriers and greater population divergence. In this instance, the environmental change has made it possible for the two previously separated populations to interact once more. However, the hybrid offspring are less likely to survive, which encourages selection against hybridization and the development of novel mating rituals, leading to the populations' continued divergence.
Understanding population dynamics necessitates being aware of the many influences that dispersal, productivity, and survival have on population growth. This is crucial for the preservation of tiny, recently established populations since stochastic births and deaths could have a negative impact on their growth or possibly cause them to go extinct.

raising the k level in the extracellular fluid to 150 mmol/l would have what effect on the action potential?
The positive charge which is outside the cell grows as fluid to 150 is extracellular then K+ increases. As a result, the interior and exterior of the cell become closer to one another.
More negative changes would occur in the potassium equilibrium potential of nerve cells. This is so because, when compared to Na+ ions, the neuron is more selectively permeable to K+ ions. Assuming extracellular K+ rises, this will alter the gradient of concentration between within and outside the cell.
The resting potential and permeability of the cell would alter as a result. It will lessen the gradient of concentration, which will reduce the amount of K+ that leaves the cell after repolarization. * The difference in concentration between extracellular K+ and intracellular K+ will flatten down as extracellular K+ rises.

by looking at the different layers of the earth, we are able to gather information about the age and environment of that area. we can also compare its age to other layers. what is the term used to describe the age of fossil layers based on its location?
The term used to describe the age of fossil layers based on its location is stratigraphy.
The area of geology known as stratigraphy is concerned with examining how rocks are layered. It is typically used to examine sedimentary rocks, which are created when tiny particles collect and solidify to form rocks.
The oldest layers will be at the bottom and the youngest layers will be at the top in an undisturbed rock sequence, according to the stratigraphic principle of superposition. Geologists can ascertain the relative ages of various rock formations and gain a better understanding of the Earth's history and evolution over time by examining the various rock strata and the fossils they contain.

The term used to describe the age of fossil layers based on its location is relative dating. Relative dating is the method of estimating a fossil's age by contrasting its location with fossils in other sedimentary rock strata.
In relative dating, the age of a fossil is estimated by comparing it with other fossils in the same layer or with fossils in other layers of sedimentary rock. This method of dating is used to determine how old a fossil is based on its placement in relation to other fossils in the same layer.
Relative dating is an important technique used in archaeology and paleontology as it allows us to determine the age of a fossil based on its position in relation to other fossils. This method is particularly useful in determining the age of fossils that are difficult to date using absolute dating methods.

How are epidemiology and toxicology similar? How are they different?
Toxicology is the examination of how harmful compounds affect the health of organisms, whereas epidemiology is the examination of disease within human populations. These include both dangerous substances made by organisms and manmade chemicals.
Explain about the epidemiology and toxicology?Epidemiology:
Thus, it appears that epidemiology is a field of study that, in particular, complements toxicology in understanding the impacts of pesticides on populations that are exposed to them. Epidemiologists do, in fact, use statistical techniques to study population health in identify the causes. They get their wisdom from the bone and flesh individuals who live around them, not in a lab.Toxicology:
Prior to approving the use of pesticides for commercial purposes, governmental authorities have primarily relied on toxicological information to assess the dangers associated with those chemicals. To find a level below that human exposure is regarded tolerable, each company that wants to market a pesticide first must put it through a series of in vivo toxicity experiments (on lab mice and rats).Both fields work to provide information about the factors that lead to disease in people and occasionally draw on one another to bolster causality claims.
Thus, the link between the hypothesized causal agent and a response is defined in great detail by toxicologists and epidemiologists alike.
