Scientists at the tar pits discovered that many of the smaller animals they extracted from the pits still exist around Los Angel
es today. But many of the larger mammals—such as woolly mammoths and saber-toothed tigers—are now extinct. Why do you think this is the case? What can scientists learn about Los Angeles’ climate history by studying the specimens found in these tar pits?
They can infer that it used to be very cold because woolly mammoths and saber tooth tigers used to live in these climates. They might have went extinct because since they are bigger, they didn't have a very big population to begin with, unlike the smaller animals that survived and have now adapted
All of life can be divided into three domains, based on the type of cell of the organism: Bacteria: cells do not contain a nucleus. Archaea: cells do not contain a nucleus; they have a different cell wall from bacteria. Eukarya: cells do contain a nucleus.
Unlike ionic bonds, covalent bonds involve the sharing of electrons between atoms. - - Final answer: <span>b. sharing of electrons between atoms.</span>
through photosynthesis setting organs convert solar energy to chemical energy which is then used to build carbohydrate molecules .the energy used to hold this molecule together is released when an organism breaks down food .cell then use this energy to perform work known as cellular respiration
