Questions and Verified Answers |
Already Graded A+
What are the levels of hierarchy? (In order) - 🧠 ANSWER ✔✔Chemical, Cellular,
Tissues, Organs, Organ Systems, Organism
Definition of Homeostasis - 🧠 ANSWER ✔✔The bodies ability to maintain a
stable internal environment
Definition of Negative Feedback Loop/Example - 🧠 ANSWER ✔✔The effector
doing its job; reverses original stimulus. Eg: thermoregulation
Definition of Positive Feedback Loop/Example - 🧠 ANSWER ✔✔When a stimulus
causes initial change to continue and exaggerate until returning to homeostasis. Eg:
birthing contractions
Body Cavities - 🧠 ANSWER ✔✔Dorsal (Cranial, spinal and meninges) and
Ventral (abdominopelvic and thoracic)

,Dorsal-Cranial - 🧠 ANSWER ✔✔Skull, contains brain
Dorsal-Spinal - 🧠 ANSWER ✔✔Vertebrae, contains spinal cord
Dorsal-Meninges - 🧠 ANSWER ✔✔Serous membranes that line the cavity and
organs
Ventral-Thoracic - 🧠 ANSWER ✔✔Pleural- Lungs; visceral and parietal pleura
Mediastinum- Mass of tissue separating the pleural cavity
Pericardial- Heart; parietal and visceral pericardium
Ventral-Abdominopelvic - 🧠 ANSWER ✔✔Peritoneal(anterior)- Stomach, colon,
liver; visceral and parietal peritoneum
Pelvic(posterior)- Ovaries, testes, bladder; visceral peritoneum
Viceral Membranes - 🧠 ANSWER ✔✔Covers the organ
Parietal Membranes - 🧠 ANSWER ✔✔Lines the cavity
Proton - 🧠 ANSWER ✔✔Positive charge, located inside the nucleus, provides
mass and identity

, Electron - 🧠 ANSWER ✔✔Negative charge, orbits the nucleus, bonds with other
atoms
Neutron - 🧠 ANSWER ✔✔Neutral charge, located inside the nucleus, adds mass
and weight
Covalent Bonds - 🧠 ANSWER ✔✔Sharing of electrons. Single, double and triple.
Ionic Bonds - 🧠 ANSWER ✔✔Loss of one or more electrons by one atom and a
gain by another creating a bond. They lose/gain to become stable.
Hydrogen Bonds - 🧠 ANSWER ✔✔When sharing electrons, maintains a slight +
charge creating weak bonds with slight - charged atoms. Attracts to the - polar end
of O, N and F and the + end of H. These bonds are weak due to unequal sharing.
Peptide Bonds - 🧠 ANSWER ✔✔Covalent bond between 2 amino acids by
dehydration synthesis. Dipeptides, tripeptides and polypeptides.
Polar Covalent Bonds - 🧠 ANSWER ✔✔The unequal sharing of electrons because
of differences in attraction. Weaker than non polar covalent. (mickey mouse shape)
Non Polar Covalent Bonds - 🧠 ANSWER ✔✔Each atom in a molecule has an
equal sharing of electrons. (infinite sign)
