| Question | Answer |
|---|---|
| What is the scientific method? | means of acquiring knowledge scientifically: the system of advancing knowledge by formulating a question, collecting data about it through observation and experiment, and testing a hypothetical answer |
| What are antibiodies | protein that fights infections: a protein produced by B cells in the body in response to the presence of an antigen, e.g. a bacterium or virus. |
| What are antibiotics | Antibiotics, also known as antibacterials, are types of medications that destroy or slow down the growth of bacteria |
| what is bacterial resistance | bacterial resistance, the ability of certain strains of bacteria to develop a tolerance to specific antibiotics to which they once were susceptible. |
| What is a virus? | A virus is a microscopic organism consisting of genetic material (RNA or DNA) surrounded by a protein, lipid (fat), or glycoprotein coat. |
| What is a prion? | infectious protein particle: an infectious particle of protein that, unlike a virus, contains no nucleic acid, does not trigger an immune response, and is not destroyed by extreme heat or cold. |
| What is gastrulation? | development of embryo: the process of cell movements by which a developing embryo forms distinct layers that later grow into different organs |
| What is an allele? | form of gene: one of two or more alternative forms of a gene, occupying the same position locus on paired chromosomes and controlling the same inherited characteristic |
| What is a gene? | basic unit of heredity: the basic unit capable of transmitting characteristics from one generation to the next. It consists of a specific sequence of DNA or RNA that occupies a fixed position locus on a chromosome. |
| Define gene expression | conversion of gene information in cell: the process by which a gene's coded information is converted into the structures operating in a cell |
| What is gene therapy? | treatment of disease by replacing genes: the treatment of a genetic disease through the insertion of normal or genetically altered genes into cells in order to replace or make up for the nonfunctional or missing genes |
| How does gene therapy work? | In most gene therapy studies, a "normal" gene is inserted into the genome to replace an "abnormal," disease-causing gene. |
| Define Adaptation. | change to suit environment: the development of physical and behavioral characteristics that allow organisms to survive and reproduce in their habitats |
| What is natural selection? | is the process by which favorable traits that are heritable become more common in successive generations of a population of reproducing organisms, and unfavorable traits that are heritable become less common. |
| What is an ecosystem? | An ecosystem is a community of plants, animals and smaller organisms that live, feed, reproduce and interact in the same area or environment. |
| How does energy flow through ecosystems? | Energy "flows" through the ecosystem in the form of carbon-carbon bonds. When respiration occurs, the carbon-carbon bonds are broken and the carbon is combined with oxygen to form carbon dioxide. This process releases the energy, |
| How does photosynthesis work? | Photosynthesis is the process where sun energy is produced into foodPhotosynthesis allows plants to combine the energy from sunlight with water and carbon dioxide and convert these materials to sugars and oxygen. Co2 comes from atmosphere which is abso |
| What are three lines of evidence for evolution? | Anatomy ~ Development~ Biochemistry |
| Scientific method can not answer | subjective questions |
| What do antibodies respond to? | Antibodies are secreted by a special group of white blood cells called lymphocytes. If an lymphocyte does not recognize a particular antigen, it will assume that it is foreign and destroy it |
| hygiene hypothesis | states that a lack of early childhood exposure to infectious agents, symbiotic microorganisms (e.g., gut flora or probiotics), and parasites increases susceptibility to allergic diseases bysuppressing natural development of the immune system. |
| how has this affected allergies | The hygiene hypothesis has now expanded to include exposure to symbiotic bacteria and parasites as important modulators of immune system development, along with infectious agents |
| What is a vaccine | a preparation containing weakened or dead microbes of the kind that cause a disease, |
| how does vaccines work? | administered to stimulate the immune system to produce antibodies against that disease |
| When can cancer occur | hello, G1 (the “restriction point)”, at the end of G2, and at the end of metaphase (M) i |
| What are some treatments | Chemotherapy— Radiation, Immunotherapy Hormone therapy |
| viral or caused by virus STD's | hepatitis B, herpes, HIV/AIDS, and HPV. |
| STD cause by Bacteria? | chlamydia, gonorrhea, and syphilis. |
| STD caused by other | trichomonas STD caused by a parasite. |
| What are the types of medical intervention / reproductive technologies help couples have a baby? | Artifical insemination, invitro~ fertilization, gamete intrafallopiam transfer, intracytoplasmic sperm injection |
| What mechanism(s) ensure only one sperm enters the egg? | The Egg Cortical Reaction Helps to Ensure That Only One Sperm Fertilizes the Egg |
| gastrulation | The development of tissues |
| why is meiosis important? | It's really important to living things, as it's crucial to reproduction and the continuation of a species |
| What are applications for cloning | for gene therapy, genetic engineering and sequencing genomes. |
| What are the applications for genetic engineering? | Genetic engineering has applications in medicine, research, industry and agriculture |
