Imagine a dog steps on a pin and pulls its foot away. Look at the reflex arc of this scenario below.
Which of the following statements best describes the image?
O The brown circle A shows neurotransmitters being released, and the blue circle B shows neurotransmitters being
absorbed.
The brown circle A is an effector, and the blue circle B is a receptor.
The brown circle A is a receptor, and the blue circle B is an effector.
The brown circle A shows neurotransmitters being absorbed, and the blue circle B shows neurotransmitters being
released.
Answers
Answer:
The brown circle A is a receptor, and the blue circle B is an effector.
Explanation:
The brown circle indicates a receptor whereas the blue circle is an effector because brown circle have sensory cells which receives the sensation due to pins into the foot and this information is taken to the central nervous system through sensory neurons while on the other hand, blue circle is an effector to which instructions comes from the central nervous system through motor neurons and as a result the dog pulls away its foot from the region where pin is placed.
Answer:
C. The brown circle A is a receptor, and the blue circle B is an effector.

Mechanical advantage = 5
Explanation:
Given the following data;
Length of input arm = 4 meters.
Length of output arm = 0.8 meters.
To find the mechanical advantage;
[tex] Mechanical \; advantage = \frac {Length \; of \; 1nput \; arm}{Length \; of \; 0utput \; arm} [/tex]

Part C
The mutation that has occurred is substitution mutation.
Mutation is defined as the random changes in deoxyribonucleic acid (DNA) that alter genetic information, and so can introduce new characteristics.
Mutation can occur in because of the following reasons stated below:
When exposed to environment saturated with ultraviolet light, it can cause cell mutation; andWhen exposed to certain chemical such as free radicals.A typical example of mutation that occurs in DNA is the substitution mutation.
Protein synthesis is the process used by cells to produce usable specific proteins as directed by the DNA.
The base sequence in DNA determines the sequence of amino acid in peptide.
Substitution mutation occurs when one base is incorrectly replaced in the complementary strand of a DNA.
From the DNA base sequence given,
Cytosine replaced Thymine; andGuanine replaced Adenine.This replacement that occurred will lead to abnormal protein synthesis.
