Biology

A:

Biology is important to everyday life because it allows humans to better understand their bodies, their resources and potential threats in the environment. Biology is the study of all living things, so it helps people to understand every organism alive, from the smallest bacteria to California redwoods and blue whales. Professional biologists often concentrate on a small subset of living organisms, such as birds, plants or bacteria.

  • What is a rough endoplasmic reticulum analogy?

    Q: What is a rough endoplasmic reticulum analogy?

    A: Perhaps the clearest analogy that can be made to describe the role of the rough endoplasmic reticulum is that of a factory assembly line. Along its surface, which Dictionary.com describes as "rough" owing to the ribosomes arrayed along its membrane, proteins are synthesized and transported for use in the cell's chemistry.

    Q: How many pounds of pressure is needed to break a bone?

    A: For smaller bones, a pressure of 25 pounds may be enough to break them. The amount of pressure that it would take to break a bone depends on the bone. Some bones are stronger than others.

  • What are habitats of fungi?

    Q: What are habitats of fungi?

    A: Fungi can live in a variety of habitats that are classified as either marine or terrestrial: in the soil, in water, and on plants and animals. Evidence suggests that some fungi have evolved closely with their partnered plant or animal to develop a productive symbiotic relationship. Fungi, which include yeast, mushrooms and mold, are classified separately from plants, animals and bacteria.

  • What is a heterogeneous mass?

    Q: What is a heterogeneous mass?

    A: According to Genes & Development, a heterogeneous mass in biology is a tumor with both normal cells and neoplastic cells, which are cells of abnormal growth tissue. Heterogeneous masses are called solid tumors and can be cancerous.

  • What is the difference between fungus and bacteria?

    Q: What is the difference between fungus and bacteria?

    A: Fungi are multicellular, eukaryotic organisms, while bacteria are single-celled prokaryotes. The cells of fungi have nuclei that contain the chromosomes and other organelles, such as mitochondria and ribosomes. Bacteria are much smaller than fungi, do not have nuclei or other organelles and cannot reproduce sexually.

  • 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.

  • What causes Siamese twins?

    Q: What causes Siamese twins?

    A: The exact cause of Siamese twins, more accurately known as conjoined twins, is not entirely known. Since the prevalence of conjoined twins is thought to be higher in southeast Asian and African populations than in Caucasian populations, Sciences 360 suggests that environmental or genetic factors may play some role in the formation of conjoined twins.

  • How do UV light bulbs inhibit bacterial growth?

    Q: How do UV light bulbs inhibit bacterial growth?

    A: Ultraviolet radiation emitted by UV light bulbs inactivates bacteria by inhibiting DNA replication when the bacteria absorbs the light. The damaged DNA cannot repair itself, causing it to die.

  • How do fungi reproduce?

    Q: How do fungi reproduce?

    A: Fungi reproduce in one of two ways: asexually through mitosis, or sexually through meiosis. Sexual reproduction occurs far less frequently than asexual production and usually only when necessary to adapt to environmental change.

  • What is proximodistal development?

    Q: What is proximodistal development?

    A: Proximodistal development is a pattern of growth observed in very young children where parts of the body closest to the trunk develop motor skills before parts of the body further away. Simply stated, gross motor skills like waving an arm develop before fine motor skills like writing legibly.

  • How do animals adapt to the rainforest?

    Q: How do animals adapt to the rainforest?

    A: Many animals have adapted to the rainforest by adopting arboreal, or tree-dwelling, lifestyles. For example, chimpanzees have incredibly strong arms and hands, which help them to climb through the many branches and vines in the rainforest understory, according to The Guardian. In addition to their impressive strength, chimpanzees possess very long and flexible arms, which also help them to climb skillfully through the trees.

  • What are the stages of meiosis 1 and 2?

    Q: What are the stages of meiosis 1 and 2?

    A: The stages of meiosis 1 and 2 are as follows: prophase I, metaphase I, anaphase I, telophase I, cytokinesis, prophase II, metaphase II, anaphase II, telophase II and cytokinesis again. There are two steps of cytokinesis during meiosis, because the cell must divide twice in order to end up with gametes that have only one set of chromosomes. DNA replicates before meiosis.

  • What is the difference between a food chain and a food web?

    Q: What is the difference between a food chain and a food web?

    A: A food web is a comprehensive map of how energy moves, in the form of food, throughout an ecosystem, while a food chain is one specific path through the web. Most food webs on Earth derive their energy primarily, if not exclusively, from sunlight. That energy is captured by plants via photosynthesis and then distributed to the consumers in the environment.
