Earth's crust are pushing against each other miles below the Earth's surface, causing earthquakes, volcanoes and the movement of the continents. Approximately 30 plates are mapped out throughout the world. The plates consist of the Earth's crust and of the mantle, which is a thick layer of hot rock. Below that lies a sea of magma.
Hope this helps
The ability of an animal to maintain a stable internal environment is called homeostasis.
It would be B) unconscious. I know this because when you're not thinking about something it is not in your conscious mind, so it would be in your unconscious mind.
The researchers will use mice instead of opossums or humans to determine whether the cells of the ear bones originated from the same embryonic cells as the cells that form the jaw in other vertebrates because in this type of experiment, organisms that are ideal are the ones that have a short life span, easy to be researched on and easy to mantain.
It will be very tedious and demanding to use opossums and humans in this type of practical experiment because,it is against the culture and norms guilding human living and existence to use humans as model organisms,opossums as well are very bad model organisms because unlike the mice,opossums are long lived and it will be very difficult to raise and maintain an opossum in a laboratory.
Humans and mice are both mammals just that human is a higher mammal but they share similar features in terms of pattern of development,though there is a clear difference during their early development,so because of the common ancestry shared by the mice and humans,the result of the experiment on the mice with share a close similarity with the pattern that is expected in humans.
A protein is a polymer of amino acids.
When amino acids are joined by dehydration synthesis (a process that removes
water to form a chemical bond), they form peptide bonds. <span>There are three main components of an
amino acid, the amino group, the side chain, and the carboxylic acid group. </span>
