Tom and jesse decided to perform an experiment to see what exercise does to blood pressure. they decided to test their friend john. below is their procedure.1. take test subject's resting blood pressure.2. have test subject do either sit ups, push ups, or sprint for one minute.3. take test subject's blood pressure. tom and jesse run the same tests on john every day for one week. running the same test, for one week, is an example ofa) validity. b) a control. c) repetition. d) replication.

The correct answer is option C, that is, repetition.  

Repetition takes place when various sets of measurements are performed at the time of one scientific investigation. While replication takes place when a scientific investigation is reproduced by another individual. Repetition refers to multiple trials, while replication is when one redo the whole experiment. In repetition, the experiment is repeated at least three times.  

after making a punnet square using bv bv bv bv you will find that the ratio will be 9: 7 or a 128.6% probability.

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.
