AP Biology Concept Checks Gina Andraos Concept Checks 1.1 1. For each biological level in Figure 1.3‚ write a sentence that includes the next “lower” level. Example: “A community consists of populations of the carious species inhabiting a specific area. ❖ The biosphere consists of all the environments that take place on Earth‚ including most regions of land‚ most bodies of water‚ as well as the ecosystems that combined to help make up the biosphere. ❖ An ecosystem consists of

Animals to be classified: Hypocalymma Angustifolium‚ Hypocalymma Cordifolium‚ Xerochrysum Bracteatum‚ Xerochrysum Viscosum‚ Pteropus Poliocephulus‚ Petaurus Australis‚ Tachyglossus Aculeatus‚ Perameles Gunnii. Has roots‚ leaves and/or flowers? Yes (therefore Flora species) No (therefore Fauna species) Average height above 100 centimetres? Is the specimen nocturnal‚ its torso covered in fur? Yes No Yes Heart shaped leaves borne opposite each other and/or Newly grown stems

Studying Life Characteristics of Living Things What are some characteristics of living things? No single characteristic is enough to describe a living thing. Some nonliving things share one or more traits with living things. Living things share the following characteristics: made up of units called cells reproduce based on a universal genetic code grow and develop obtain and use materials and energy respond to their environment maintain a stable internal environment change over time

meeting these challenges‚ based on the mechanisms of biology and the principles of physics. Biology studies our life‚ its variety and complexity and physics looks for mathematical laws of nature and makes predictions about the forces that drive idealized systems. The main challenge of Biophysics is to span the distance between the complexity of life and the simplicity of physical laws. In other words biophysics acts as a bridge between biology and physics. Biophysicists’ main job is to study life

The Ted Talk video entitled “Animations of Unseeable Biology” describes the process of DNA replication. As the speaker Drew Berry explains‚ this process is repeatedly occurring and is performed mechanically. He provides us an animation of how a chromosome is replicated and split with the help of microtubules. Microtubules are straight tubes that are made up of proteins and it resides within a cell. This hollow tube allows the mitosis phase to occur. The copying of DNA is transported across the microtubules

• Chapter 7 o Online questions • The fluid mosaic model is now generally accepted for the description of all biological membranes • Transmembrane segments of membrane proteins anchor membrane proteins in the lipid bilayer. • A ganglioside is not a phospholipid. • Thin-layer chromatography separates lipids based on hydrophobicity. • Unsaturated fatty acids have double bonds and increased membrane fluidity. • Cholesterol increases fluidity at low temperatures and decreases fluidity at high temperatures

How does movie Gattaca relate to biology? The movie Gattaca directed by Andrew Niccol is about “a genetically inferior man assumes the identity of a superior one in order to pursue his lifelong dream of space travel”. During the process (to become as same as Jerome Morrow‚ the superior)‚ Vincent goes through lots of different operations‚ including physical and genetic operations. As we watched it and saw the operations and the doctors in the beginning of the movie‚ we connected happenings to the
