What is a community vs ecosystem? An ecosystem describes all the living organisms (biotic components) with their physical surroundings (abiotic components) in a given area. A community describes only the living organisms and their interactions with each other. What are types of community? Richard Millington defines five Different Types Of Communities: Interest. Communities of people […]

What are Euglenids? Euglenids (euglenoids, or euglenophytes, formally Euglenida/Euglenoida, ICZN, or Euglenophyceae, ICBN) are one of the best-known groups of flagellates, which are excavate eukaryotes of the phylum Euglenophyta and their cell structure is typical of that group. Is euglena autotrophic or heterotrophic? The Euglena is unique in that it is both heterotrophic (must consume […]

What body system transports nutrients? The blood circulatory system (cardiovascular system) delivers nutrients and oxygen to all cells in the body. It consists of the heart and the blood vessels running through the entire body. What body system transports nutrients and waste? The circulatory system delivers oxygen and nutrients to cells and takes away wastes. […]

Why it is important for scientist to follow this process? It provides an objective, standardized approach to conducting experiments and, in doing so, improves their results. By using a standardized approach in their investigations, scientists can feel confident that they will stick to the facts and limit the influence of personal, preconceived notions. Why is […]

What is an example of a negative feedback loop in the menstrual cycle? This is an example of negative feedback . Progesterone maintains the uterus lining (the thickness of the uterus wall). If the egg has not been fertilised, the corpus luteum dies and progesterone levels drop. This causes menstruation, where the uterus lining breaks […]

What type of bond is formed between oxygen and hydrogen in water? Covalent bonds Will hydrogen and oxygen form an ionic bond? Ionic bonds usually occur between metal and nonmetal ions. For example, in water (H2O) each hydrogen (H) and oxygen (O) share a pair of electrons to make a molecule of two hydrogen atoms […]

What is the force acting between charges? Coulomb’s law, or Coulomb’s inverse-square law, is an experimental law of physics that quantifies the amount of force between two stationary, electrically charged particles. The electric force between charged bodies at rest is conventionally called electrostatic force or Coulomb force. What is the force between two charged objects? […]
