Complete the following analogy.

chromosome is to cactus as gene is to

desert
weeds
needle

Option C, needles

Explanation:

In a cactus plant, pointed thorn like leaves also called as needles are found. if we compare a chromosome with a cactus plant, then the genes can be compared to the needles. As needles are found on cactus plant, genes are found on chromosome.  

Desert and weeds do not form any structural part of the cactus thus they cannot be compared with gene lying of chromosome

the offspring would all be white. if the parents are both white flowers then they have the genotype rr, which when crossed results in an all white punnet square.

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.
