The shoulder girdle is a complex of five joints that can be divided into two groups. Three of these joints are true anatomical joints while two are physiological ("false") joints.[explain 1] Within each group, the joints are mechanically linked so that both groups simultaneously contribute to the different movements of the shoulder to variable degrees.

Endangered species with very small populations are especially at risk of loss of genetic diversity due to option(d) i.e, genetic drift.
A species that is threatened with extinction in the near future, either globally or within a certain political jurisdiction, is known as an endangered species. Invasive species, habitat degradation, poaching, and other issues may put endangered animals in danger.
Genetic drift is the arbitrary change in the frequency of a gene variant in a population. Gene variations may totally vanish due to genetic drift, which would limit genetic diversity. Additionally, it has the potential to make previously uncommon alleles far more common and even fixed. Drift lowers genetic diversity in populations, which may limit a population's capacity to adapt to new selective pressures. In smaller populations, genetic drift is more pronounced and has more severe consequences. Particularly in the case of rare and endangered species, this effect is significant.
The complete question is:
Endangered species with very small populations are especially at risk of loss of genetic diversity due to:
immigration.
mutation.
natural selection.
genetic drift.

The symbol on a regulatory marker
that indicates hazards such as rocks or stumps is an Orange Diamond. Regulatory
markers are types of non-lateral markers such as white and orange markings that
are used as navigation aids that give directions, warn of dangers and marks
controlled locations. Orange diamond shapes warns of dangers such as rocks,
stumps or construction.
