Answer: 60 to 100 beats per minute.
Explanation:
Pulse is the number of times the hear pump blood out into the systemic circulation per minute
The lower this range the more efficient the heart is. In trained athletes the pulse rate is about 40bpm.
This shows the heart pumps blood at a faster rate to meet the demands of the muscles and other organs involved in the strenuous activities.
It can be measured by placing two fingers on the thumb side of the wrist,and count numbers of beats heard for 15 seconds.The counted number should multiplied by 4 to obtain beats per minute.
<span>The discoverers of DNA were not James
D Watson and Francis Crick. They are the first scientist to formulate an
accurate description of the DNA’s (deoxyribonucleic acid) complex ,
double-helical structure. They discovered that base pairing nucleotides must
be; adenine and thymine; and cytosine and guanine. These base pairs are held
together by a hydrogen bond, atype of chemical reaction that s easy to break
and easy to reform. The statement is “DNA
is a double helix made of two strands linked together with hydrogen
bonds.”</span>

Answer:
NGC 5236 aka M83 and the Southern Pinwheel Galaxy is a barred pinwheel type galaxy. NGC 4151 is categorized as a Seyfert type galaxy.
Explanation:
Barred spiral galaxies such as NGC 5236 generally have a elongated center that is called a bar. From that bar are arms that spiral. The arms are composed of star and stellar material. The spaces in-between hold much less stellar matter.
Seyfert type galaxies, such as NGC 4151, are generally characterized by a core that is bright, compact, and is not shaped like a bar. This type of galaxy generally has spiral arms as well.
