Describe how living conditions change for two tidal organisms
gayaneshka [121]
The shoreline is one of the harshest and most changeable environments for living creatures. The changing tides shift the environment dramatically within a sub-daily cycle. Here, we can consider two typical shoreline organisms, and the changing environment they must endure. Within the rocky shore environment, an octopus would be within the shallow but open sea environment during high tide, and water temperature and salinity conditions would be fairly constant. During low tide, the octopus might become trapped in a rock pool. This environment is dramatically different. The water temperature and salinity might increase drastically with exposure to solar radiation. The octopus is also more vulnerable to predation by humans and other land animals. Within the sandy shore environment, sand clams would be actively positioned at the interface of the sand and water, and will be actively filtering sea water for detritus. During low tide, the sand would be exposed to the air, and the clams would burrow down into the sand so as to avoid dessication.

A normal chromosome and its homolog carrying an inversion are given. the dot (•) represents the centromere. normal: a b c • d e
kotegsom [21]

The type of inversion is Paracentric inversion.

There are two types of inversion at the chromosome level, depending on the centromere:

Paracentric inversions:

the centromere is not included in the inversion.

Pericentric inversions:

The centromere is included in the inversion which can transform a metacentric chromosome into an acrocentric chromosome.

the structure that will form during synapsis is inversion loop.

These inversions are balanced rearrangements but at the moment of meiosis they cause difficulties in pairing. There is most often formation of a pairing loop. The occurrence of recombination in the inverted segment causes the formation of abnormal gametes by duplication / impairment.
