The f1 generation may have genes for short plants just that the genes for long plants are dominant over the genes for short plants(recessive) so when cross pollination happen and that two f1 long plants which are homozygous cross pollinate, the recessive genes have a chance of being paired up in new offspring(F2 offspring) thus the possiblity of short plants in f2 generation

For example, the cross between two pure plants (homozygous), being a dominant characteristic over another, in case high on short.

High = AA
Short = aa

F1 = AA x aa = 100% Aa = high = heterozygous

F2 = Aa x Aa
 
      A    a
A  AA  Aa
a  Aa  aa

Therefore, of this crossing, we have
75% High plants (AA e Aa)
25% short plants (aa)

This is possible because the heterozygote plant had the short plant allele.

A scientist was observing a population of sea cucumbers in coastal waters. Over a 10-day period, she collected the following inf
Rus_ich [418]

The abiotic factors that could cause the sea cucumbers to differ their distance from one another are temperature, time of the day, and humidity. The biotic factors that could influence are the organisms around these creatures. Furthermore, the independent variable in this study is the time of the day where observed are the average distance between these sea creatures and their output, the distribution of sea cucumbers as the dependent variable.

Hypothesis: There is a link between the time of the day and the distance of sea cucumbers amongst each other.
