7. genottype example: Tt (heterogenous)

8. Pedigree chart shows patterns and genders
D
9. Antibiotics cannot kill viruses because bacteria and viruses have different mechanisms and machinery to survive and replicate. The antibiotic has no “target” to attack in a virus.
D
10. Natural selection: Organisms adapted to environment sure and reproduce

28.The primary function of the plasma membrane is to protect the cell from its surroundings. Composed of a phospholipid bilayer with embedded proteins, the plasma membrane is selectively permeable to ions and organic molecules and regulates the movement of substances in and out of cells.https://courses.lumenlearning.com/boundless-biology/chapter/components-and-structure/ "REGULATES MOVEMENT OF MATERIALS IN/OUT"

(A) TRUE
30. DESCRIBE THE DIFFERENCE BETWEEN HYPERTONIC, HYPOTONIC, AND ISOTONIC SOLUTIONS.
HYPERTONIC having a higher osmotic pressure than a particular fluid, typically a body fluid or intracellular fluid.
HYPOTONIC: having a lower osmotic pressure than a particular fluid, typically a body fluid or intracellular fluid
ISOTONIC denoting or relating to a solution having the same osmotic pressure as some other solution, especially one in a cell or a body fluid.

11.Humans have 23 pairs of chromosomes, for a total of 46 chromosomes.
In fact, each species of plants and animals has a set number of chromosomes. A fruit fly, for example, has four pairs of chromosomes, while a rice plant has 12 and a dog, 39. choice D
