A cellular biologist wants to double check a statement that cells spend 90% of their life in Interphase compared to the other parts of the cell's cycle. The biologist harvests onion root tips
in the laboratory to stain for examination. In this case the null hypothesis is "If cells spend 90%
of their life in Interphase then we will be able to calculate the relative time existing between
Interphase and the other portions of the cell life cycle." 1000 cells were counted under a
microscope. Of the 1000 cells; 875 were counted in Interphase while the remaining 125 cells
were in another portion of the cell life cycle. What are the genotype frequencies for this group of
cells?

answer: angiosperms

dicots

angiosperms are highly evolved plants, they produce seeds which are enclosed within in a carple. these are the largest group of plants on earth. they include trees, shrubs, herbs and small flowering plants. angiosperms exhibit a flowering stage in their life cycle. the flower serves the function of reproduction and fruit formation in majority of angiosperms. dicot is the term used to describe flowering plants that have two seed leaves. dicots are plants which develop seeds which split into two parts called cotyledons. each cotyledon contains one embryo.

here, a small purple flower development indicates that the plant belongs to angiosperms and having two embryonic leaves indicates it belongs to dicots.  

in 1859, charles darwin set out his theory of evolution by natural selection as an explanation for adaptation and speciation. he defined natural selection as the "principle by which each slight variation [of a trait], if useful, is preserved".
