Fossils are the preserved remains or traces of animals, plants, and other organisms from the past. Fossils are important evidence for evolution because they show that life on earth was once different from life found on earth today.
I know carbon dioxide is, I don’t think oxygen and water vapour are. I don’t know the others, sorry
Protein breakdown into amino acids is the statement that correctly explains the complex molecule.
Option (c);
<u>EXPLANATION:</u>
Cells in our body carry put several chemical reactions which in turn keep us healthy. All these reactions are collectively called metabolism. With the breakdown of complex molecules, it releases a lot of energy into the body.Through this process, Proteins are broken down into amino acids.
Various enzymes, specifically pepsin and hydrochloric acid breaks proteins into individual amino acids. They on further broken into a-keto acids. These amino acids reduces body weight and improves energy in the human body.
<span>Answer B, skin, is an example of epithelial tissue. All other answer are examples of different types of tissue; Bone being osseous tissue, fat being connective tissue and muscle being muscle tissue. Nervous tissue is one of the types that has cells that expand across the entire human body. Nerves can be both long and reach every corner of the body. The other type of tissue that can cross the entire body is epithelial. This type of tissue does not produce large cells that span great distances on/in the body. But, these cells do provide the lining throughout the body and are the tissue that makes up the protective layer called skin. Both connective tissue and muscle tissue form large amounts of tissue in the body but they do not expand to all reaches of it.</span>
