Answer:
D. The nerves exit the central nervous system in the head and from the lumbar spine.
Explanation:
The preganglionic neurons transmit the nerve impulses through the cranial or spinal nerves that arise from the brain, to the postganglionic neurons from where the nerve fibers that relay these nerve signals to the different viscera and effector organs, located along the spinal cord
Answer: CONDITIONS FOR HARDY
No mutations should appear in the beetle population because new alleles would change the allele frequencies
There should be random mating among beetles
There should be no natural selection on the beetle population
The population of beetles must be large enough so that genetic drift is avoided
There should be no migration of beetles into or out of the population.
CONDITIONS FOR EVOLUTION-
Natural selection favors green beetles
Purple mutants appear among the Beatles
Preferred mates are red, so these individuals reproduce
Large numbers of brown beetles were killed in a forest fire
A significant number of yellow beetles left.
Explanation: I only added about half the sentence of each answer because it’s to long.
Answer:
May alter the specificity for its substrate
Explanation:
The active site of an enzyme refers to the specific region of an enzyme that serves as the binding site for its one or more substrates. Binding of substrates to the active site of their enzymes is required for catalysis. Enzymes are highly specific for their substrates. Type of amino acids present in the active site of the enzymes and their interactions with substrates regulate the specificity of the enzyme. If a mutation substitutes the amino acid of the active site, it may increase or decrease the specificity of the enzyme for its substrate.
Answer:
The correct answer is option B. "Raoul's practice is massed; Scarlett's is distributed".
Explanation:
A massed practice condition is defined as a task that its performed by an individual without taking a significant amount of rest. Since Raoul is only taking 5 seconds of rest between trials, his practice is massed. On the other hand, distributed practice conditions involve resting for longer periods of time. Scarlett is resting 40 seconds between trials, which represents a longer period of time that the trial itself (30 seconds), therefore her practice is distributed.
