Answer:
The correct option is D) determines normal activity of the urinary tract.
Explanation:
The peripheral nervous system controls involuntary functions and acts. The parasympathetic tone is known as a constant activity that maintains the parasympathetic nervous system, this allows that at any given time, the activity of this system can increase or decrease, that is, the value of the tone has implications in the increase or decrease in the activities of the stimulated organ, in its contraction or relaxation. Parasympathetic stimulation raises the tone of the detrusor muscle (causes it to contract) of the urinary bladder and relaxes the trigone and the urethral sphincters(which muscles help to keep the urethra closed, that is, help the urine staying in the bladder), favoring micturition.
Okazaki fragments are the discontinuous segments of the lagging strand.
Okazaki fragments are located on the template strand which dictates the newly synthesized DNA away from the direction of the movement of replication fork. It is the building block for DNA synthesis of the lagging strand and on one template strand, the DNA polymerase synthesizes the new DNA in the opposite direction that is away from the replication fork movement.
The results of the di-hybrid cross of pea plants with round and yellow seeds was the evidence that Mendel fond that supported his law of independent assortment.
<u>Explanation:</u>
Law of independent assortment states that the alleles of two different genes are inherited independent of each other. The law of independent assortment was formulated by Gregor Mendel . Cross of a pea plant with yellow and round seeds with a pea plant having green and wrinkled seeds gave evidence of the law of independent assortment.
When it comes to seed color yellow color is dominant to green. When it comes to seed shape round seed is dominant to wrinkled seed. Let the letter R represent round seed and R represent wrinkled seed. The letter Y represent yellow seed and letter y represent green seed.
The genotype of pea plant with round and yellow seed is RRYY and the genotype of round and wrinkled is rryy. The cross between round yellow and wrinkled green can be represented as follows
Gametes RY ry
F1 generation RrYy RrYy RrYy RrYy
All the plants of the F1 generation have round and yellow seeds.
The F1 generation plants are then bred together
RRYY RrYY RRYy RrYy RrYY rrYY RrYy rrYy RRYy RrYy RRyy Rryy RYy rrYy Rryy rryy
r
Are the progenies with phenotypes like round yellow, round green, wrinkled yellow and wrinkled green.
The combination of the characters of roundness and color is observed in the F2 generation proves that the characters of round and yellow as well as wrinkled and green doesn’t appear strictly in combination. This means that they are independently assorted which proves the law of independent assortment.
