About half of a body’s weight is muscle. Muscle tissue is of three distinct types: skeletal, cardiac, and smooth. Each type has a unique structure and a specific role. Skeletal muscle<span> moves bones. </span>Cardiac muscle<span> contracts the heart to pump blood. The </span>smooth muscle<span> tissue that changes shape to facilitate bodily functions of intestine and bladder. Here are more details about the structure and function of each type of muscle tissue in the human muscular system. </span>
Three basic categories of cells make up the mammalian body: germ cells, somatic cells, and stem cells.
They probably will be abiotic because they’re non living. If my answer was wrong, kindly remove my comment. Thanks
<h3><u>Answer and explanation;</u></h3>
- DNA is a double stranded molecule. Covalent and hydrogen bonds pray important roles in the functioning of DNA molecules.
- <em><u>Covalent bonds occur within each linear strand and strongly bond the nucleotide bases, sugars, and phosphate groups occurring both within each component and between components.</u></em>
- <em><u> Hydrogen bonds occur between the two strands and involve a base from one strand with a base from the second in complementary pairing.</u></em>
- Hydrogen bonds helps the complementary base pairs in DNA; guanine with cytosine and adenine with thymine to connect to one another. The hydrogen bonds between these complementary pairs helps keep the two strands of DNA helix together.
we know that difference of 10 dB represents 10 times louder sound, so by applying this,
the difference is 40 db means 10 × 10 × 10 × 10 times louder sound,
hence, the sound outside the library is 10000 times louder than the sound in library.
