Organisms that inhabit intertidal zones must be able to tolerate radical changes in temperature, salinity, and moisture and also be able to withstand wave shock. Intertidal zone is the coastal area alternately exposed and submerged by tides. Tide pool animals and plants are well adapted to the intertidal zones. Some adaptations include; the ochre sea star can tolerate a longer time period exposed to air than many other sea stars. They regularly withstand up to eight hours of exposure during low tides.

How does polyploidy allow speciation to occur in a single generation? Polyploid offspring produce gametes earlier in the mating
wariber [46]

Answer:

Genomic differences between polyploid offspring and their diploid parents prevent them from successfully interbreeding, causing reproductive isolation between the two generations.

Explanation:

Speciation is an ecological and biological process through which new species are formed due to isolation.

In plants, polypoidy involves the possession of two complete sets of chromosomes and it leads to the origin of new species. Also, the two sets of chromosomes comprises of triploidy (69 chromosomes) and tetraploidy (92 chromosomes).

As a result of the genomic differences between polyploid offspring and their diploid parents, this usually prevent them from successfully interbreeding and consequently causing reproductive isolation between the two generations.

You have to find the acceleration first. so you would use the equation a=Vf-V0/t.
This would be 0-20/0.5 which equals to be a=-40. then you plug this in to the force equation wich is F=ma. F=55 x -40.  F= -2200

Hope this helps!
