What are two things that can be done to maximize the chances of recovering parasites from a fecal smear?
RideAnS [48]
<span>Sedimentation - uses solutions of lower specific gravity than the organisms, which concentrated in the sediment. This technique is recommended for general diagnostic laboratories because it is easy to perform and less prone to technical errors.

Flotation - this technique uses solutions of higher specific gravity than the parasitic organisms so the organisms float and the debris sinks producing a cleaner material while the disadvantage is that walls of cysts and eggs collapse that may blocking its identification.<span>

Why would rapid change in climate potentially lead to ecological problems?
nadya68 [22]

The rapid change in the climate would potentially lead to ecological problems because evolution is unlikely to occur quickly enough to keep pace with biome changes.

<h3>What do you mean by Evolution?</h3>

Evolution may be defined as the process of growth and development or the theory that organisms have evolved and developed from past organisms.

Biome changes occur due to the fact of evolution. Both evolution and biome changes synergistically move forward to support organisms' life in a much better way.

Therefore, the rapid change in the climate would potentially lead to ecological problems because evolution is unlikely to occur quickly enough to keep pace with biome changes.

The genome size of E.coli is approximately 5X106 bp and can be replicated in 30 minutes. The human genome size is 3X109 bp, abou
Oksana_A [137]

Answer:

Human genome has various replicons.

Explanation:

A replicon which is a unit of DNA, has potential to get replicated independently. So, the DNA replication occurs simultaneously at various replicons as a result of which human genome takes much less time than estimated to get replicated .

In contrast to this, prokaryotes like E.coli have only one origin of replication and thus one replicon due to which replication is restricted to once per cell cycle.
