In one experiment, the heart rate of a mollusk at rest was measured at 0.3 cycles/s. How many times did the mollusk's heart beat in 1 min?

18 times

Explanation:

Heart rate = 0.3 cycles/s

Heart rate =

number of cycles = heart rate x time

But, 1 min = 60 seconds

⇒ number of cycles = 0.3 x 60

                                  = 18

Thus, the number of times that the Mollusk's heart beat in 1 min is 18.

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.
