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…

1) Biological theories Biological explanations of crime assume that some people are ‘born criminals’, who are physiologically distinct from non-criminals. The most famous proponent of this approach is Cesare Lombroso. What biological factors contribute to criminal behavior? Factors such as low intelligence, poor diet, impulsivity and hyperactivity, hormones such as testosterone and cortisol, and environmental…

Pea Protein. How do I choose protein powder? The Bottom Line Choose a protein powder that’s ideally unsweetened with as few ingredients as…

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…

Chemical agents are hazardous substances that usually would make you sick immediately. Examples of chemical agents include mustard gas, cyanide, and sarin. Biological agents are usually viruses or bacteria which may take several days to make you sick once you are infected. Is bacteria physical chemical or biological? Biological hazards include microorganisms such as bacteria,…

Using the Voice Synthesizer to lure the Minigunners to activate a rigged weapon crate was one of the the safest way to take them out, as Batman didn’t need to even get close to them, but this only worked once. How do you beat the machine gunner in Batman Arkham Knight? How do you remove…

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,…

Preserved specimens are not considered hazardous waste and normally may be disposed of in the trash. To dispose of specimens in the trash, place specimens and any associated tissues in a sealable plastic bag or the bags in which they were shipped. Seal the bag and place it in an additional plastic trash bags. How…

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 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:…

Answer all questions simply and generally. Never speak ill of the other parent. Always validate their feelings. Reiterate that it’s not their fault. Make a list of the dad’s good qualities. Identify father figures in their life now. What do you do when a child misses an absent parent? Offer items that belong to the…

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…

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 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.…

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…

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…

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…

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…

Time is very important when an unconscious person is not breathing. Permanent brain damage begins after only 4 minutes without oxygen, and death can occur as soon as 4 to 6 minutes later. Machines called automated external defibrillators (AEDs) can be found in many public places, and are available for home use. What happens after…
