Reproductive isolation caused by different mating habits or physical separation leads to the divergence of two groups within a population into separate species through the process of speciation.
When different mating habits cause two groups within a population to be less likely to mate with each other, this leads to reproductive isolation. The outcome of reproductive isolation is often the divergence of the two groups into separate species, a process known as speciation. The driving forces behind this include natural selection, mutation, and genetic drift, which act over time to increase the genetic and phenotypic differences between the populations. As a result, even if individuals from the two groups are brought together, they may no longer be capable of producing viable or fertile offspring, thus cementing the reproductive isolation.
One example of this process involves habitat isolation, where a population of a species moves or is moved to a new habitat that does not overlap with the rest of the species. Over time, this separation can lead to speciation due to the lack of genetic exchange and the different selection pressures in the new environment.
The distance, measured in degrees, north and south of the equator is referred to as _____.
the prime meridian
the arctic circle
longitude
latitude
Answer;
-Latitude
Explanation;
-The distance, measured in degrees, north and south of the equator is referred to as latitude.
-Latitude is the measurement of distance north or south of the Equator. It is measured with 180 imaginary lines that form circles around the Earth east-west, parallel to the Equator. These lines are known as parallels. A circle of latitude is an imaginary ring linking all points sharing a parallel.
-The Equator is the line of 0 degrees latitude. Each parallel measures one degree north or south of the Equator, with 90 degrees north of the Equator and 90 degrees south of the Equator.
Latitude is an angular measurement that indicates the position of a location on the Earth's surface relative to the equator. The distance, measured in degrees, north and south of the equator is referred to as latitude.
The equator is defined as 0 degrees latitude and is the reference point for measuring latitude. As one moves north of the equator, the latitude increases in positive values, while moving south of the equator results in negative values.
Latitude lines, also called parallels, are imaginary horizontal lines that circle the Earth parallel to the equator. They are evenly spaced and become progressively smaller as they move away from the equator towards the poles. The maximum latitude is 90 degrees at the North Pole and -90 degrees at the South Pole.
Latitude is a geographic coordinate that determines a location's position in relation to the equator. It is measured in degrees, with 0 degrees representing the equator, positive values representing the northern hemisphere, and negative values representing the southern hemisphere.
Latitude lines run parallel to the equator and are used to establish horizontal positions on the Earth's surface.
Therefore, the distance, measured in degrees, north and south of the equator is referred to as latitude.

Which example describes migration caused by overcrowding?
Migration caused by overcrowding is exemplified by 'B. Hordes of rats flee a city when their numbers exceed the carrying capacity', as it reflects the population density reaching a point where resources are insufficient, necessitating migration to find more suitable environments.
The example that describes migration caused by overcrowding is: B. Hordes of rats flee a city when their numbers exceed the carrying capacity. This represents a situation where the population density of the rats becomes too high, leading to insufficient resources to support them, prompting a migratory response to seek out new areas with more available resources.
Migration is a natural behavior seen in many species and can be driven by various factors, including the search for food, mating opportunities, and more suitable climatic conditions. Animals may exhibit different types of migration, such as obligate migration, where species always migrate, facultative migration, where they only migrate under certain circumstances, and incomplete migration, where only part of a population migrates while the rest remain.
Two reasons why it is easy to harvest perlemoen
Perlemoen is reasonably easy to take available of the ocean and do not really required huge and expensive equipment. The poachers take out millions of rands worth of Perlemoen with relatively simple and cheap equipment such as wet suites, googles and flippers. The most expensive equipment they use are their boats and vehicles. In comparison with the lucrative industry the costs of poaching are low. Perlemoen are often the smaller, younger abalone of the species that are taken because they are quite simply and easier to harvest.
1. The younger perlemoen are found closer to the shoreline and often bunched together and they can get a whole whack of them at one spot.
2. The strandlopers harvested the perlemoen from the rocks during low tide without the need for diving.

Describe the impact of a waterborne pollutant on an aquatic community. write a 100-word report on how that pollutant affected aquatic life, what the effect was, and whether the effect is linked to biomagnification.
Water pollution can have a significant impact on aquatic communities, affecting aquatic life and the overall ecosystem. Pollutants such as heavy metals can biomagnify in the food chain, leading to higher concentrations in predatory fish species. This can have harmful effects on the fish themselves, as well as on the organisms that consume them.
Explanation:Water pollution is the contamination of water by an excess amount of a substance that can cause harm to human beings and/or the ecosystem. Pollutants can enter water supplies from point sources, which are readily identifiable and relatively small locations, or nonpoint sources, which are large and more diffuse areas. Waterborne pollutants can have a significant impact on aquatic communities, affecting aquatic life and the overall ecosystem. For example, pollutants such as heavy metals like mercury and cadmium can biomagnify in the food chain, leading to higher concentrations of these toxins in predatory fish species. This can have harmful effects on not only the fish themselves, but also on the birds or humans that consume them. Biomagnification is a process where the concentration of a toxin increases as it moves up the food chain.
Blood type is an example of a trait that's inherited by
A. incomplete dominance.
B. gender-specific alleles.
C. polygenic inheritance.
D. codominance.
Blood type is an example of a trait that's inherited by co-dominance.
CO-DOMINANCE:
Co-dominance is a type of inheritance pattern in which the alleles of a gene are neither dominant nor recessive over one another, hence, are simultaneously expressed. Co-dominance goes against the mendelian pattern of inheritance, which states that the dominant allele is expressed over the recessive allele. In co-dominance, both alleles are physically expressed. An example is blood type inheritance where alleles A and B are both expressed in an individual with AB genotype.Learn more about blood type: https://brainly.com/question/17058567?referrer=searchResults

Explanation: Taking the test right now
A plant that is homozygous for red flowers is crossed with a plant that is homozygous for white flowers. in the case of incomplete dominance, the flowers of the offspring will be
Incomplete dominance is defined as the genetic condition, in which a reduced ratio of the dominant allele is expressed. The offspring produced by the purebred parents is an intermediate between the two genotypes.
Let the genotype for purebred red flowers be - RR
Let the genotype for purebred white flowers be - WW
The cross between the true-breeding parent will is RR x WW.
The cross between purebred red and purebred white flowers will result in 100% pink progeny due to incomplete dominance.
Incomplete dominance is the phenomenon in which the dominant allele is expressed in the reduced ratio, such that the dominant allele does not mask the recessive allele completely, resulting in an intermediate offspring.
Therefore, the incomplete dominance will result in all the pink flowers, an intermediate between red and white flowers.
