  • What is the function of bony processes?

    Q: What is the function of bony processes?

    A: According to Right Diagnosis, bony processes are parts of bones that stick out from the main body of the bone, serving as attachment sites for muscles, ligaments or other connective tissues. Each of the different processes that exist in the body are named, such as the traverse processes, which are part of the vertebrae, as explained by KnowYourBack.org.

  • Why are scientific names important?

    Q: Why are scientific names important?

    A: Scientific names are important because they allow people around the world to communicate accurately about animal species. With the help of international rules on naming animals, zoologists avoid naming the same species twice. This means that each scientific name is unique.

  • Why do leaves turn brown?

    Q: Why do leaves turn brown?

    A: Leaves turn brown mainly due to environmental stress. Hot, dry and windy weather can cause a plant’s rate of transpiration to exceed the rate of water absorption. When this happens, more water is lost from the leaves through transpiration than is absorbed by the roots from the soil, leading to leaf scorch.

  • What is the difference between diffusion and osmosis?

    Q: What is the difference between diffusion and osmosis?

    A: Osmosis is a particular type of diffusion in which water crosses a semi-permeable membrane to an area with a greater solute concentration, whereas standard diffusion often allows the free movement of both solutes and solvent toward equilibrium. Diffusion in general is the net movement of molecules in solution from areas of higher concentration to areas of lower concentration. Osmotic pressure is potentially very powerful, with osmotic pressure being the only force necessary to move water from the roots to the tops of the tallest trees in the world.

  • At what temperature do viruses die?

    Q: At what temperature do viruses die?

    A: While extreme high or low temperatures technically do not kill viruses, the influenza virus and many others are deactivated at temperatures ranging from 165 to 212 degrees Fahrenheit, the boiling point for water. Since viruses lack many of the basic structures and functions necessary to be considered a living organism, they technically cannot die.

  • What is a complex organism?

    Q: What is a complex organism?

    A: Complex organisms have specialized tissues, such as nerves, organs or flowers. In contrast, simple organisms, such as amoeba or yeast, exist as a single cell. Larger organisms tend to have more specialized cells that smaller ones.

  • How is fungi spread?

    Q: How is fungi spread?

    A: Fungi spread by forcibly ejecting spores, making their own wind and allowing natural wind and water to spread their spores. Some spores have hair-like parts that help them disperse more easily in water. Some fungi use insects, such as flies, to help them spread their spores.

  • Does a fungus have a nucleus?

    Q: Does a fungus have a nucleus?

    A: Members of the kingdom Fungi have cells with a nucleus. Fungi cells have a cell wall and membrane-bound organelles. The presence of membrane-bound organelles causes fungi to be classified as eukaryotes.

  • How are bacteria different from animal and plant cells?

    Q: How are bacteria different from animal and plant cells?

    A: Plants and animals are multi-cellular organisms composed of eukaryotic cells, while bacteria are single-cell prokaryotic organisms. Each eukaryotic cell of a plant or animal includes a central nucleus containing DNA and membrane-bound organelles, such as endoplasmic reticulum and mitochondria. A bacterial cell has no nucleus or membrane-bound organelles.

  • What are carbohydrate chains?

    Q: What are carbohydrate chains?

    A: Carbohydrate chains are chains composed of two to potentially hundreds of carbohydrate compounds called monosaccharides. Once two of these monosaccharides combine, they form a disaccharide. If there are more than two but fewer than 10 monosaccharides in a chain, it is called an oligosaccharide, and a polysaccharide is a carbohydrate chain that consists of hundreds of monosaccharides.

  • What is the difference between ectoplasm and endoplasm?

    Q: What is the difference between ectoplasm and endoplasm?

    A: Endoplasm and ectoplasm are names for the inner and outer portions of an amoeba’s cytoplasm. Ectoplasm is the clear outer cytoplasmic layer of an amoeba. Endoplasm, on the other hand, is the inner granule-rich cytoplasm of the amoeba.

  • How are coral reefs made?

    Q: How are coral reefs made?

    A: According to the National Oceanic and Atmospheric Administration, coral reefs are formed when coral larvae attach themselves to rocks or other hard surfaces found under water along the edges of islands and along coasts. Additionally, plants may also accumulate within the reef. The process is slow and aided by limestone deposits, which settle on the plant and animal life.

  • Why is pH important to living organisms?

    Q: Why is pH important to living organisms?

    A: Living organisms depend on a proper balance of hydrogen and hydroxide ions in order to maintain essential physiological processes. Scientists use pH to express the concentration of hydrogen ions in a solution. Many organisms have tightly regulated systems to maintain the pH within the required range.

  • How do multicellular organisms grow?

    Q: How do multicellular organisms grow?

    A: Multicellular organisms may evolve into large and complex beings, but they all begin as a single cell and pass through several defined stages of development. All beings, from small plants and insects to large elephants, giraffes and even humans, begin as single, simple cells, called fertilized eggs.
