The major structural difference between chromatin and chromosomes is that the latter are
labwork [276]

Answer:

The major structural difference between chromatin and chromosomes is that the latter are more organized and condensed.

Explanation:

Chromatin is genetic material packaged into a complex by special proteins (histones). That complex is in the form of uncoiled structures, so chromatin fibers are long and thin. Chromatin structure is permissive to DNA replication, transcription and recombination events.

On the other hand, chromosomes are highly condensed structures of genetic material that are formed just before the cell division.

Which would be a consequence of the removal of predators from a population such as the Trinidadian guppy population?a .The nitro
natulia [17]

Answer:

The correct answer is option b. "Guppy color patterns would change; guppies would produce fewer but larger offspring; the nitrogen excretion rate would increase and the rate of growth of primary producers such as algae would increase".

Explanation:

The Trinidadian guppy is a species of fish with the scientific name <em>Poecilia reticulata</em>. Just like almost all species, its population is regulated for multiple factors, one of them being the presence of predators. The removal of Trinidadian guppy predators would result in multiple consequences:

- Guppy color patterns would change. The fish have a complex coloration determined largely by predation avoidance.

- Guppies would produce fewer but larger offspring. This adaptation has been proved in an experiment at which the fish was introduced one a low predation environment. The report proved that evolution can take place in less than 10 years.

- The nitrogen excretion rate would increase. It has been reported that predation reduce Trinidadian guppy nitrogen excretion by 40%. Removing the predators will case the nitrogen excretion rate to increase due to an increase in the fish food intake.

- The rate of growth of primary producers such as algae would increase. This is an effect of the increase of nitrogen excretion rate, which benefits algae population to growth.

Why aren't organisms on the seafloor crushed by water pressure?
fiasKO [112]

Answer: The deep-sea organisms found today have undergone evolution in the past and are very complex now because their body structure also varies from that of the organisms that are present at a lower depth.

The bodies of these organism does not contain any air cavities in which the pressure could exert. It is because of this, the organism are quite solid without any air in their bodies, thereby they can withstand extreme high pressure.
