An incompletely dominant gene controls the color of chickens so that BB produces black, Bb produces blue, and bb produces white. A second gene controls comb shape, with the dominant gene R producing a rose comb and r producing a single comb. If a chicken that is pure-breeding for both black color and rose comb is mated to a white chicken with a single comb, what fraction of the offspring in the F2 generation will be black with a rose comb

answer; i believe that the correct answer is (lung);

bc blah

explanation:

bc blah

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.  

many other transport proteins, often called pumps, move materials against a concentration gradient. active transport drives molecules across a membrane from a region of lower concentration to a region of higher concentration. this process, shown in figure 5.1, uses transport proteins powered by chemi- cal energy.
