In which stage do vertebrate embryos or offspring show the most similarities?

a. earliest stages
b. middle stages
c. just before birth
d. after birth

Option B. Middle stages

Explanation:

During early stages of development, all the embryos are quite similar to each other. Embryos of different organism such as human being, fish etc. share common look alike at certain developmental stages because they all have originated from a common ancestor

However, the maximum similarity arises in the middle of embryonic development stage particularly known as phylotypic stage

Hence, option B is correct

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.  

that would be called plucking : )

explanation:

''plucking, also referred to as quarrying, is a glacial phenomenon that is responsible for the erosion and transportation of individual pieces of bedrock, especially large "joint blocks". as a glacier moves down a valley, friction causes the basal ice of the glacier to melt and infiltrate joints (cracks) in the bedrock."
