Explanation:
Symbol Representation
I- laci mutant cannot bind to the operator
Is laci mutant always bind to the operator
OC Operator mutant that prevent repressors binding
F’ the wild type operator, O+, and laci gene on a plasmid
L lacZYA genes
I+ O+ L+ Inducible
I+ OC L+ Constitutive
I+ OC L+, F’ Constitutive
I- O+ L+, F’ Inducible
Is O+ L+ no transcription
Is O+ L+, F’ no transcription
Collagen Fiber. this is the strongest and most common connective fiber; it has tensile strength; its appearance is long, straight, and unbranched; examples: tendons and ligaments. reticular fiber.
Answer:
Xerophyte survival characteristics:
Thick cuticle.
Stomatal closure.
Reduction in # of stomata.
Stomata hidden in crypts or depressions in leaf surface (less exposure to wind and sun).
Reduction in size of transpiration surface (lower leaf only).
Increased water storage.
Explanation:
Xerophyte adaptations increase water intake, limit water loss, and store water efficiently. Water intake adaptations include deep or widespread roots, and high salt content to increase osmosis. Xerophytes have thick cuticles, lost or finely divided leaves, reduced stomata, and CAM photosynthesis
I believe this would be true
