Answer:
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
Hi!
A lizard lies on a rock to raise its body temperature. This is called B. Ectothermy.
Answer: Congenital insensitivity to pain is a condition that inhibits the ability to perceive physical pain. While A reflex arc is a neural pathway that controls a reflex. In vertebrates, most sensory neurons do not pass directly into the brain, but synapse in the spinal cord. This allows for faster reflex actions to occur by activating spinal motor neurons without the delay of routing signals through the brain.
Explanation: So I would believe so
Answer:
A) The catalyst makes lower energy pathways available.
Explanation:
A catalyst is a substance which speeds up a chemical reaction without itself being used in the reaction. Activation energy is the thresh hold energy which is required to initiate a chemical reaction. In the absence of catalyst, the activation energy is high therefore reactions are slower. But, presence of catalyst lowers the activation energy required to initiate the reaction as a result of which the reaction gets an alternate energy pathway to proceed which is responsible for speeding up the reaction.
