Neurons and not in a ganglion. With dendrites facing the external surface of the cribriform plate and axons that pass through the cribriform foramina with terminal end at olfactory bulbs. The ORNs located in the olfactory neuroepithelium of the nasal cavities.
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.

Flagellum. This is the only thing I could come up with because you did not provide an image.
Answer: Gene flow is the movement of alleles from one population to another as a result of the migration of individuals. This causes a reduction in the differences between populations. ... Genetic drift is a change in allele frequencies due to change of events in a small breeding population.
Answer:
Lactase and Carbonic anhydrase are enzymes;These are organic catalyst (proteins) that speed up the rate of organic chemical reactions,in living organism.They acts on the organic reactions by reducing the activation energy for the reaction to occur,but remain unchanged at the end of the reaction.
Explanation:
Lactose is an enzyme in the small intestine needed for the break down of Lactose,a diasaccharides to glucose and galactose.it is acts in the brush borders for this to occur.
Carbonic anhydrase is an enzyme in the cytoplasm needed for the the catalysis of C02 with H20 to form Carbonic acid(H2CO3),protons, and hydrogen carbonate in a reversible reactions.
The catalysis is needed for regulation of blood pH during respiration.
As stated up,molecules of catalyst do not change in the organic chemcial raxction they act upon.Rather they lower the activation energy for the faster completion of the rate of reaction.
Therefore in the question above the amount of the catalayst will remain the same it was at the beginning of the reaction.This is the major properties of catalysts.
