• What causes the tail of a tadpole to shrink and disappear?

    During metamorphosis the tadpole will develop back legs first, then front legs. Around 6 weeks of life the mouth starts to widen. Sometime around 10 weeks the froglet’s eyes start to bulge out and the tail begins to shrink and eventually disappear through the process of apoptosis and then their forelegs emerge. How does a…

  • How does the structure of a molecule affect its function?

    Each molecule has a characteristic size and shape that determines its function in the living cell. The shapes of molecules are determined by the positions of the atoms’ orbitals. When an atom forms covalent bonds, the orbitals in its valence shell are rearranged. Does structure determine function in biology? One of the overarching themes of…

  • What is the difference between chemical and biological agents?

  • What type of evidence is fiber evidence?

    Like hair, fibers are considered class evidence. Fibers have probative value because they can create connections, or associations. For example, a suspect may deny he was ever in a particular place or ever in contact with a particular person. Is fiber physical or biological evidence? Physical evidence consists of tangible objects, such as biological material,…

  • How do you calibrate a microscope with an eyepiece graticule?

    How do you calibrate an eye graticule? Why is an eyepiece graticule calibrated? Therefore one graticule division is equal to 4.9 μm. The calibrated eyepiece graticule can be used to make measurement of any cells or other structures viewed with the microscope on that magnification. What is an eyepiece graticule? What is an eyepiece graticule?…

  • How do you calculate surface area and volume in biology?

    How do you find the surface area to volume ratio of a sphere? For a sphere, surface area is S= 4*Pi*R*R, where R is the radius of the sphere and Pi is 3.1415… The volume of a sphere is V= 4*Pi*R*R*R/3. So for a sphere, the ratio of surface area to volume is given by:…

  • How do you explain an absent parent to a child?

  • How are organisms classified into domains?

    Organisms can be classified into one of three domains based on differences in the sequences of nucleotides in the cell’s ribosomal RNAs (rRNA), the cell’s membrane lipid structure, and its sensitivity to antibiotics. The three domains are the Archaea, the Bacteria, and the Eukarya. How are organisms classified according to hierarchy? Each of this level…

  • Can I put my girlfriend’s child on my health insurance?

    Yes, a stepchild is eligible to be a dependent on your health plan up to the age of 26 . If your coverage is an employer group plan that provides benefits to children, you will be given at least 30 days to enroll the new dependent. An eligible child can be a biological child, adopted…

  • How do you calculate Nbod and CBOD?

    How do you calculate theoretical oxygen demand? Write balanced reaction for the carbonaceous oxygen demand. CH2(NH2)COOH + 1.5O2 → NH3 + 2CO2 + H2O. Write balanced reactions for the nitrogenous oxygen demand. NH3 + 1.5O2 → HNO2 + H2O. HNO2 + 0.5O2 → HNO3 Determine the ThOD. ThOD = (1.5 + 2) mol O2/mol glycine.…

  • What is the connection between biology and culture?

    Culture relates to nature (our biology and genetics) and nurture (our environment and surroundings that also shape our identities). How does cultural evolution interact with biological evolution? In the regime of human culture the sources of variation are certain acts based on human creativity, such as innovations for instance. In cultural evolution imitation and certain…

  • What are the biological factors of panic disorder?

    The Biological Theory of Panic Disorder Serotonin, norepinephrine, and dopamine are chemicals that act as neurotransmitters or messengers in the brain. They send messages between different areas of the brain and are thought to influence one’s mood and anxiety level. Does panic disorder have biological vulnerability? With respect to anxiety disorders, genetic predisposition has been…

  • What is central dogma and mutation?

    The central dogma states that the pattern of information that occurs most frequently in our cells is: From existing DNA to make new DNA (DNA replication?) From DNA to make new RNA (transcription) From RNA to make new proteins (translation). How does central dogma relate to biology? The central dogma of molecular biology is a…

  • Is race a valid biologically meaningful concept Why or why not?

    No, race is not an appropriate, valid, or biologically meaningful concept. The concept of race is a typological leftover from pre-evolutionary, taxonomic interpretations of biological variation. Human variation is clinal. What does it mean to say that race becomes biology? Epidemiologic evidence shows that, in a very certain sense, race is biology. There are, in…
