An individual who has a high level of cardiovascular fitness will have a LOWER Resting Heart Rate at any activity level than an individual who is unfit AND an individual who has a high level of cardiovascular fitness will have a LOWER Stroke Volume than an individual who is unfit. True / False.

An individual who has a high level of cardiovascular fitness will have a LOWER Resting Heart Rate at any activity level than an individual who is unfit AND an individual who has a high level of cardiovascular fitness will have a LOWER Stroke Volume than an individual who is unfit is a true statement.

Explanation:

Resting heart rate is a cardiac marker and at normal conditions, the resting heart rate of an adult ranges anywhere between 60 to 100 beats per minute.

As far as efficiency of heart or cardiovascular fitness is concerned, a lower resting heart rate is the general benchmark. An athlete who exercises properly may have a resting heart rate even less than 60 which is good for heart health.

Exercise strengthens the heart or cardiac muscles which provide more energy for the cardiac muscles to pump more blood per one heart beat as one exercises. So without increasing the heart rate, more blood is pumped and increases stroke volume.

This is the reason why the stroke volume is also increased in a person with high level of cardiovascular fitness.

Aerobic exercises are the best to lower resting heart rate.  

Whereas cardiac muscles become weak due to lack of exercise, which requires the heart to beat more times to pump blood per minute. Lack of exercise, anxiety, stress, dehydration, lack of adequate sleep, and any other underlying medical conditions can increase the resting heart rate.

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.
