After months of grueling research, karl has come to the conclusion that brand a cola tastes better than brand b cola. why would people claim that this is not a valid conclusion?

Explanation:

The missing options of this question are:

A)Scientific conclusions need to be based on fact and not opinion.

B)His friends are wrong, and this is a valid conclusion.

C)Karl did not follow the scientific method.

D)Karl is not a real scientist.

The correct answer is option A) "Scientific conclusions need to be based on fact and not opinion".

One of the most important characteristics that a scientist needs to include in her or his reports, is to make the conclusions based entirely on facts. In this case, declaring that a Brand of cola tastes better than other is not a fact, because taste is a perception that depends upon people's opinion. A proper scientific conclusion would be for instance declaring that according to the people's opinion evaluated on the research, most of them believe that Brand A cola tastes better than Brand B cola.

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.
