In an experiment that compares a combination mental-physical practice condition to an all-mental practice condition, an all-physical practice condition, and a no practice condition, the typical results show that participants in the combination mental-physical practice condition would learn the skill
a. as well as or better than those in the all-physical practice condition.
b. about as well as those in the all-mental practice condition.
c. about as well as those in the no practice condition.
d. The results would depend on the combination of the amount of mental and physical practice.
The combination mental-physical practice condition is effective to learn the skill as well as or better than those in the all-physical practice condition. Mental-physical practice enhances both cognitive and physical skills.
Mental practice, also known as mental/skill rehearsal, refers to the cognitive (i.e., thinking) rehearsal of a given skill prior to its execution.
It has been shown that mental practice can be effective for enhancing the performance of both cognitive and physical skills.
The mental-physical practice has been shown to be helpful to enhance self-motivation, confidence, and reduce feelings of anxiety.
Mental practices always must be employed to supplement physical practices instead of replacing such physical exercises.

the spinal cord achieves the function of locomotion through __________.
Answer:
groups of neurons called central pattern generators
The spinal cord achieves the function of locomotion through groups of neurons called central pattern generators, hence option A is correct.
What are the groups of neurons in the spinal cord?Even when cut off from the brain and sensory inputs, "central pattern generators" (CPGs) nerve networks in the spinal cord can generate rhythmic motions like swimming, walking, and hopping.
In the absence of sensory or descending inputs that contain precise timing information, central pattern generators are neural networks that, when triggered, may create rhythmic motor patterns like as walking, breathing, flying, and swimming.
The spinal cord facilitates the movement of bodily components, accidents frequently result in people being unable to utilize certain body parts like the legs.
Therefore, the spinal cord achieves the function of locomotion through groups of neurons called central pattern generators, hence option A is correct.

Dna is synthesized through a process known as DNA Replication.
DNA is synthesized through a process known as - DNA replication or semiconservative replication.
DNA replicationsynthesis of new DNA. a double-stranded DNA molecule is copied to produce two identical DNA molecules.is an essential process because, whenever a cell divides, the two new daughter cells must contain the same genetic information or DNA.the replication takes place in the following steps:step 1in the nucleus of the cell the DNA double helix separates after that an enzyme named DNA helicase attaches to the DNA molecule and moves along the molecule and 'unzips' the two strands of DNA
Step 2since nucleotides are floating in the nucleus that means there are A, G, T and C's floating around also. these are bases that form hydrogen bonds with the bases of DNA strands.
Step 3
the enzyme they call DNA polymerase catalyzes the formation of the sugar-phosphate units at the sides of the helix and connects one base pair to the next one
Thus, DNA is synthesized through a process known as - DNA replication or semiconservative replication.
