An atom has a mass number of 23 and an atomic number of 11. How many neutrons does this atom have?
How do enzymes work?
What is Enzymes decrease the activation energy required for a reaction, speeding it up
Skeletal muscle tissue utilizes involuntary contractions to create movements.

What does cyanosis tell you about a person's health?
What is Low oxygen levels in the blood
Give an example of negative feedback mechanism in the human body?
What is regulation of blood glucose.
What are covalent bonds
Explain what happens when a RBC is placed in a hypertonic solution.
What is A red blood cell placed in a solution where there is a high solute concentration, which causes crenation (shrinking) as water leaves the cell
What is the function of osteoclast and how is it performed.
What is the osteoblast are the bone breakers "bone resorption". Using hydrolytic enzymes and hydrogen ions
In which layer of the epidermis do cells begin to produce keratin and start to die as they move towards the surface?
What is Strata Granulosum
Which serous membranes cover the external surface of the organs within the abdominal cavity?
What is Visceral Peritoneum
Write the basic example of an exchange reaction. General form
What is AC+ BD --> AD+ BC
What happens when a tissue heals by fibrosis?
What is Scar tissue is formed, and that portion of the tissue loses functional ability
Explain the process of synthesis that happens with melanocytes and keratinocytes
What is Melanin is synthesized by the melanocytes and then by exocytosis the keratinocytes pick up the vesicles and covers their DNA with melanin like an umbrella to protect from DNA damage.

What is Chemical, Cellular, Tissue, Organ, Organ System, Organism.
Which of the following is true about the relationship between electronegativity and dipole moments in a molecule?
A molecule with atoms of equal electronegativity will have a strong dipole moment
A molecule with atoms of different electronegativity will have a dipole moment
Electronegativity does not affect the dipole moment of a molecule
A molecule with a dipole moment must have atoms with equal electronegativity
What is atoms of different electronegativity will have a dipole moment

Tyrosinase
What is growth?
Catabolic reactions outweigh Anabolic reactions
What process leads to the formation of a disaccharide?
What is the dehydration synthesis of two monosaccharides
Explain osmosis
What is Water molecules moving from an area of low solute concentration to an area of high solute concentration
