Answer:
1. silent mutation
2. non sense mutation
3. missense mutation
Explanation:
1. <u>in a silent mutation</u>, the substituted base will code for <em>another</em> codon that will get translated to the <em>same</em> amnio acid
2. <u>in a non sense mutation</u>, the substituted base will code for a <em>STOP</em> codon that would cause the production of a faulty, usually non functional protein, <em>missing</em> some amnio acids.
3. in a missense mutation, the substituted codon codes for a <em>different</em> amino acid and this can have a small to great effect on the product protein based on its function. eg: sickle cell anemia where you've substituted a polar amino acid with a non polar one, thus causing severe consequences
The hydrolysis of atp and preparation for reattachment to the thin filament by the myosin head called the recovery stroke.
<h3>What is myosin ? </h3>
Myosins are a class of motor proteins well recognized for their functions in the contraction of muscles and a variety of other eukaryotic motility processes. They are ATP-dependent and in charge of motility based on actin. By Wilhelm Kühne, the first myosin was identified in 1864.
<h3>When the myosin pulls the actin what is happening?</h3>
The actin is drawn along by the myosin head as it advances in the direction of the M line. The filaments migrate nearer the M line by around 10 nm as the actin is tugged. The power stroke is the name given to this motion because it is where force is generated.

<h3><u>Explanation;</u></h3>
- <em><u>The Silurian Period was a third period of the Paleozoic Era that occurred from 443 million to 416 million years ago. This period occurred after the Ordovician Period and was then followed by the Devonian Period.</u></em>
- Silurian period is the period that many biologically significant events took place. There was a widespread radiations of crinoids, continued priliferation and expansion of the brachiopods and also the oldest known fossils of coral reefs.
