Below are some key events that took place during the long history of life on Earth. Arrange them in the correct sequence: First land plants (kingdom Plantae) First eukaryotic life (domain Eukarya) Adaptive radiation of mammals (class Mammalia) Evolution of chloroplasts Cambrian explosion First aerobic organisms (those that utilize cellular respiration) First land vertebrates (tetrapods) First multicellular organisms First living cells
Which of the following organisms appeared on earth first? Prokaryotes Eukaryotes Animals Plants
If your blood pressure raises, blood is allowed to flow to the capillaries which decreases blood pressure. On the other hand, if your blood pressure drops some capillaries are deprived of blood flow to raise blood pressure. This is an example of which property of life? A) All life transforms energy B) All life is organized C) All life maintains homeostasis D) All life evolves E) All life grows and develops F) All life can reproduce
Approximately how long ago did homo sapen (humans) first appear on Earth 2,000 years ago 5-7 million years ago 65 million years ago 150,000 - 200,000 years ago Hominins developed their unique larger brains before acquiring the ability to move on two feet. True False the production of atmospheric oxygen in Earth's environment started with photosynthesis by prokaryotes photosynthesis by multicellular eukaryotes photosynthesis by single celled algae photosynthesis by land plants Homologous structures among animal provide evidence for evolution in that theses structure are all produced by the same gene different in different animals, but are modifications of the same basic structure similar in function, but of different basic structure all different structures within the same species
Which of the following is NOT true about creationism? * no answer There is no extinction of organisms because organisms can always survive as long as they try hard enough. The earth was created only 6000 years ago because the evidence of the rocks suppor that idea. Any great change is due to small but cumulative changes that occur over long periods of time. All organisms are perfect because they are created to be able to survive in their habitat.
Be able to place the following events into their correct eon: Origin of the earth Origin of prokaryotes Increase in atmospheric oxygen Origin of eukaryotes Radiation of mammals Earliest human ancestors Origin of genus Homo

Please someone help me with Bio homework, thank you
1. The representation must be on a linear scale (not logarithmic) . Have the student to present the years in a way that really helps the audience to visualize just how long Earth has been around compared to how short an amount of time humans have been on earth, for example. 2. Have the student include a legend that allows the audience to interpret how they are representing the time since each event has occurred (e.g., 1cm = 1000 years, 1mL = 100,000 years, 1 second = 10,000 years) 4. The student is to include the following important events: Start of life (~3.8 GYA[1]) Origin of eukaryotes (~2–3.5 GYA - your choice within that range) Origin of multicellularity (~2 GYA) Origin of Homo sapiens(~200 KYA) Present time (0 YA) 5. The student is to include at least 3 other events. The events must relate to the history of Earth, not human history. The student will need to find the dates of these events Formation of Earth Oxygenation of Earth’s atmosphere Origin of vertebrates Mass…

Earth’s history is divided into unequal time intervals. The boundaries between the intervals mark significant geological (very early Earth) or evolutionary events on Earth’s history. Example: The boundary between the Precambrian eon and the Phanerozoic eon is marked by the rapid evolution and diversification of organisms with hard body parts. The time intervals are eons, which are subdivided into eras. The eras are subdivided into periods. The periods are further subdivided into epochs (not shown on figure). What is our current eon ______________, era _______________, and period _______________ Age boundary between the Hadean eon and Archean eon __________________ Age boundary between Archean eon and Proterozoic eon __________________ Age boundary between Proterozoic eon and Phanerozoic eon ________________ Age boundary between Paleozoic era and Mesozoic era ____________________ Age boundary between Mesozoic era and Cenozoic era ____________________ What…
