What is reduced leveling?
A reduced level is the vertical distance between a survey point and the adopted level datum
What causes many endangered species that are now found only in zoos to have very little genetic variations?
Founder effect refers to the loss of genetic variation when a new colony is established by a very small number of individuals from a larger population. As a result of the loss of genetic variation, the new population may be distinctively different.Bottleneck effect is an evolutionary event in which a significant percentage of a population or species is killed or otherwise prevented from reproducing, and the population is reduced by 50% or more, often by several orders of magnitude.Population bottlenecks increase genetic drift, as the rate of drift is inversely proportional to the population size.They also increase inbreeding due to the reduced pool of possible mates.
Does genetic drift increase or decrease genetic variation in populations and why?
It is important to understand that each individual has different genes. Genes can be lost if an individual dies without reproducing. To answer your question: There are two type of effects caused by Genetic Drift. The founder effect happens when a few species inhabit a new territory. If only those species reproduce then there are less genes in the gene pool and that leads to less variation. This can happen if storms sweep birds to a previously uninhabited island. The other effect is the bottleneck effect. This happens if a disease or poaching drastically reduces the number of individuals in a population. Since there are less individuals who can reproduce there are not as many genes that can be passed down.
Sparking between contacts can be reduced by inserting a resistance?
Capacitor in parallel with contacts.
What is the difference between reduced bore and full bore valve?
In Full bore ball valve, The bore dia will be same as internal dia of the pipe.In reduced bore, the bore dia is reduced than the ID of pipe.
When most populations of a wide ranging amphibian species are lost and the few remaining populations are widely separated you expect to see that?
gene flow between populations is reduced
What is the basis of inbreeding depression?
Inbreeding depression is the reduced fitness of a population caused by inbreeding. Inbreeding reduces genetic diversity, meaning populations are less genetically adaptable - and greatly increases the chances of genetic diseases and disorders. Inbreeding is most commonly associated with reduced reproductive and viability traits.
How does genetic drift lead to a change in a populations gene pool?
Genetic drift reduces variation in a population through allele loss, there are 2 situations of GD: a) Bottleneck effect: number of individuals is reduced significantly by a random event b) Founder effect: few individuals are separated and establish their own population both situations result in different allele frequency representations in new populations from their previous population`s
Some people mate living things that are closely related in procress called?
inbreeding. This can lead to a higher risk of genetic disorders and reduced overall fitness in the offspring. Inbreeding is commonly practiced in selective breeding programs to maintain specific traits, but it is generally discouraged in natural populations to promote genetic diversity and long-term survival.

What is reduced diversity in a population?
This questions is two broad and has too many variables to answer effectively.
Which animal populations were greatly reduced in the early 1800s and early 1900s in Antarctica?
I think it was either seals or whales.
How many people live in Antarctica in winter?
The 'winter-over' populations in the research stations are significantly reduced from the summer populations. Perhaps five percent of the summer population remains for the winter season.
