Answer:
Furthermore, the axial skeleton consists of six parts: the skull, the ossicles of the middle ear, the vertebral column, hyoid, rib cage, and the sternum while the appendicular skeleton consists of limbs and girdles. Axial and appendicular skeleton are the two main parts of the endoskeleton of vertebrates including humans.

Answer:
Water can hydrogen bond.
Explanation:
Liquids become gases once they are heated to a certain temperature. Heat is a form of energy. This change occurs when the intermolecular forces between the liquid molecules are energized enough to break. This breakage is necessary because gaseous molecules exist individually and do not interact with one another. That being said, it takes more heat to boil water because its intermolecular forces are stronger than methanes.
Intermolecular forces (IMF) are a result of partial charges on the molecular atoms that cause temporary bonds to form between molecules.
Methane is a nonpolar molecule, meaning each atom can only have slight partial charges. The strongest IMF methane participates in are London Dispersion Forces.
Water, however, is a polar molecule, with the hydrogens having strong partial positive charges and the oxygens having strong partial negative charges. This allows water to participate in a very strong IMF called hydrogen bonding. Again, because these partial charges are so strong, the water molecules can form stronger IMFs.
<u>*When molecules have stronger IMFs, they require more energy(heat) to overcome them.*</u>
D is correct. Newton's first law of motion states that an object in motion stays in motion. The orange is moving and then the tray stops making the orange move forward because of inertia. Hope this helps! ;)
Answer:
The respiration of a suspension of yeast cells was measured by determining the decrease in pressure of the gas above the cell suspension. The apparatus was arranged so that the gas was confined to a constant volume, 16 cm3 and the entire pressure change was caused by the uptake of oxygen by the cells. The pressure was measured in a monometer, the fluid of which had a density of 1.034 g/cm3. The entire apparatus was immersed in a thermostat at 37. In a 30 minute observation period the fluid in the open side of the manometer dropped 37mm. Neglecting the solubility of oxygen in the yeast suspension, compute the rate oxygen consumption by the cells in mm3 of O2 (STP) per hour
