  • Why is blood considered to be a tissue?

    Q: Why is blood considered to be a tissue?

    A: Scientists categorize blood as a connective tissue for two primary reasons. According to Rutgers University, blood originates in embryo in the mesoderm, one of the three primary layers of cells; blood shares this origin with other kinds of connective tissue. And, like other kinds of connective tissue, blood plays a connective role with respect to the systems within the human body.

  • What is the difference between anabolism and catabolism?

    Q: What is the difference between anabolism and catabolism?

    A: Anabolism is a process in which the liver creates new proteins from digested nutrients, while catabolism involves the breaking down of proteins into essential amino acids. Both are vital to the body's metabolism and maintaining healthy cell function.

  • What are examples of non-infectious diseases?

    Q: What are examples of non-infectious diseases?

    A: Asthma, diabetes, stroke, cancer, chronic obstructed pulmonary disease and cystic fibrosis are examples of non-infectious diseases, which are commonly known as non-communicable diseases or NCDs. While viral infections, such as the flu, measles and HIV, typically spread from person to person, NCDs aren't contagious and can't be contracted from bacteria. In most cases, NCDs are inherited genetically or develop in response to specific environmental conditions.

  • How do insects excrete waste?

    Q: How do insects excrete waste?

    A: Insects excrete waste through an anus, just as most other animals do. Insects have complete digestive systems, meaning that food travels in one direction through a continuous tube, called the alimentary canal. This contrasts with animals that have two-way digestive systems, such as starfish, anemones and jellyfish. Complete digestive systems allow for specialization of the structures, leading scientists to consider them more advanced than two-way systems.

  • At what temperature does human blood boil?

    Q: At what temperature does human blood boil?

    A: Blood boils at approximately the same temperature as water, around 100 degrees centigrade. Human blood is essentially a water solution, made up primarily of water. The salt in the blood, a concentration of approximately 0.9 percent, does little to increase the boiling point of human blood.

  • What do evolutionists believe?

    Q: What do evolutionists believe?

    A: Evolutionists tend to believe and accept some form of the Darwinian argument that a natural selection process and environmental factors are responsible for all the forms of life on Earth. Life, as it exists today for evolutionists, is a result of a series of random cosmic events that caused chemical processes to create life-forms. All life-forms on Earth are related from the most minuscule to the most complex.

  • What is a producer in biology terms?

    Q: What is a producer in biology terms?

    A: Biologists use the term producer to describe green plants that synthesize food through the process photosynthesis. Producers form the bottom rung of the food chain, and they serve as food for animals, which bear the name consumers. Without producers, the food chain would collapse because all other living organisms depend on them for food.
