Answer:
Planet diameter = 2p × (distance to the planet) × (planet's angular size in degrees)/360°. Planet volume = (p/6) × (planet diameter)3. Density = mass/volume.
Explanation:
Beneatha lost her faith on her youthful idealism. She always mocks Asagai’s idealistic dream for African independence. She no longer support African heritage and she thinks more about the problem of Africa is facing. She has a dream of going to medical school which may not happen anymore.
C. Producers are able to use the sun to create their energy. Consumers have to eat something else to get their energy. For example, Grass is a producer as it uses sun light for nutrients. A rabbit (a consumer) eats the grass for its nutrients. A fox would then consume the rabbit, also making it a consumer.
Birds are thought to have evolved from dinosaurs. Through the study of the fossil record, scientists have discovered that some dinosaurs have similar anatomical features to birds. The fossil record shows that some dinosaurs have similar bone structure and some even have feathers.
The fossil record even shows that some dinosaurs display similar behaviours to birds like laying eggs in nests, incubating and caring for their young.
Answer:
B. A drug that prevents the conversion of glucose into pyruvate
Explanation:
<em>Streptococcus mutans</em> is a facultatively anaerobic bacterium, i.e., a microorganism capable of producing ATP by both aerobic (when there is oxygen), and anaerobic (i.e., when there is no oxygen available) conditions. This bacterium is observed in the human oral cavity where causes the majority of tooth decay. <em>S. mutans</em> can digest carbohydrates (e.g. glucose, fructose and lactose) in order to produce lactic acid, which contributes to tooth decay. Glycolysis is the fermentation of glucose to pyruvate in anaerobic conditions, and thereby it is expected that a drug capable of preventing the conversion of glucose into pyruvate in anaerobic conditions is effective to prevent cavities caused by <em>S. mutans</em>.
