Canine teeth are not as useful as it is in animals while archaeopteryx has the character of both birds and reptiles.
<h3>What are vestigial organs?</h3>
The vestigial organs are those organs that have no apparent function in the body which means that the body can do without them.
Examples of vestigial organs in the body are:
The canine teeth is a type of teeth in mammalian dentition and is said to be vestigial because man can do without it.

Answer:
15% is adenine
Explanation:
adenine is paired with thymine meaning the amounts will be equal
High frequency, short / small wavelength
Attached is the image of the concerned ECG reading.
In reading the ECG, first you read the heart rate. To read the heart rate, you must count for the number of small boxes in between QRS complexes, specifically R-R intervals. These number of small boxes will then be used to divide 1500. In this example, there are 20 small boxes between R-R intervals. 1500 divided by 20 is 75, so the heart rate of this ECG reading is 75 beats per minute.
<em>Another way, albeit less accurate, is to count the big squares between R-R intervals and instead of dividing it by 1500, you divide it by 300.</em>
