Lipids are a group of organic compounds including fats, phospholipids, and steroids.
Lipids are a group of organic compounds that do not dissolve easily with water. Lipids include fats, oils, monoglycerides, diglycerides, triglycerides, phospholipids, hormones, vitamins (such as vitamins A, D, E, and K), and steroids. Lipids functions by storing energy for organisms, as chemical messengers between cells, tissues, and organs, and they also function as structural parts of cell membranes.
Answer:
Atmospheric oxygen is too reactive
Explanation:
Criminal evidence is any physical or verbal evidence presented in court to prove a specific crime. Evidence can take different forms and can be used by the accused to prove innocence. Admissible evidence, moreover, is the use of testimony (oral or written such as affidavit), exhibits (physical objects), documentary material or demonstrative evidence ( in the form of representation of an object including photos, x-rays, videotapes, movies, sound recordings, diagrams, forensic animation, maps, drawings, graphs, animation, simulations or models). All are presented before a judge or jury to prove a point or element in a case. In the choices above, six of them can qualify as individual evidence except numbers 3. Number 8, however, is questionable since it has incomplete description as to where and how is the paint was chipped.
Answer:
Scientists learn how climatic changes during the ice age affected life in this region by analyzing specimens found in these tar pits
Explanation:
La Brea Tar Pits are a group of tar pits in Los Angeles. Many preserved remains of ancient organisms (i.e., fossils) were extracted from the tar, including, among others, Western horses, prehistoric camels, three-toed tapirs, rodent bones, insects, mollusks, wood, plants, etc. The oldest fossils have been dated to be approximately 38,000 years ago by radiometric techniques. Moreover, the Last Glacial Period was the most recent glacial period within the Quaternary glaciation, which encompassed the period between 115,000 to 10,000 years ago. This period (LGP) encompassed the Last Glacial Maximum (LGM), which occurred about 20,000 years ago. In consequence, many of the fossils found in La Brea Tar Pits evidence how the ice age affected life in this region. Moreover, many of the fossil species extracted from the tar are still present today, thereby indicating how these species adapted to fluctuating climatic conditions, whereas certain species couldn't adapt fast enough as the environment changed and therefore they went extinct.
