Earthworms have two muscles which is used in locomotion. Both muscles are circular and longitudinal (inner layer of the series of muscles). The diameter of the earthworms body is reduced when the circular muscles are contracted which makes them appear to be thin. The worm appears short when the longitudinal muscles contract thus, its length is reduced.
Amphioxus on the other hand, have two unique muscle fiber types. This includes deep fibers and smaller but mitochondria-rich superficial fibers. E<span>ach of which has its own innervation.</span>
Lysozymes are under the enzymes-functional class of proteins. Enzymes are the ones responsible for the acceleration of chemical reactions. These are the macromolecular biological catalysts. <span> When we say enzymes, these are proteins which are directly related to the facilitation of the biochemical reactions. These include lactase and pepsin. You can usually hear these when learning about specialty diets or digestive medical conditions. Some of the examples of this protein’s presence are found in tears, human milk, saliva, and mucus. It is because of their ability to break down bacterial cell walls in order to protein improvement and nucleic extraction of efficiency make these lysozymes important </span>proteins<span> in living organisms. The gene responsible for the encoding of the lyzozome enzyme is called the LYZ gene.</span>
<h3>Answer:</h3>
B] Meters per second
<h3>Explanation:</h3>
- We know that speed = distance ÷ time. So hour per km and second per Mile cannot be the unit of average speed.
- Now the remaining options are <u>miles per hour</u> and <u>Meter per second.</u>
- In comparison with both of these;
we know that metre per second is the SI unit of average speed and hence the answer is <u>meters</u><u> per </u><u>second</u>.
