Where do sperm go after leaving the epididymis?
OA. Ejaculatory duct
OB. Seminiferous tubules
C. Vas deferens
OD. Urethra
c is the right answer
Explanation:
hope it will helpful for you.
On leaving the epididymis, the sperm is expelled into the vas deference, thus the correct option is option C.
Where is the sperm stored?The sperm are stored in the epididymis. Upon ejaculation, the sperm leaves the epididymis and migrates to the vas deferens.
The vas deferens create a protective fluid that protects the sperm while it's out from the urethra. If sperm does make it into the vagina, there’s a chance that it will fertilize the female egg.
Epididymis is a long tube that functions to transport sperm from the testis to the vas deference. While traveling through the different parts of the epididymis the sperm gets mature and acquires the ability to swim. So epididymis plays an important role in the maturation and transport of sperm.

(Here's the table used for context)
Family / parent phenotype cross / phenotype ratio in offspring
1 / gray fur x black fur / 3 gray fur: 2 black fur
2 / gray fur x black fur / 0 gray fur: 5 black fur
3 / black fur x black fur / 1 gray fur: 3 black fur
4 / gray fur x gray fur / 4 gray fur: 0 black fur
Using the allele symbols N and n identify the most likely genotype of the parent wolves in family 1 and the most likely genotypes of the parent wolves in family 2. Be sure to identify which genotype is for the parent with gray fur and which genotype is for the parent with black fur in each family.
ok so, I'm having trouble understanding. i believe that the inheritance pattern could be dominant-recessive, but now I'm not too sure. families 1 and 2 have 5 offspring (which doesn't accommodate a dominant-recessive punnett square as that only accounts for 4 offspring). so i tried thinking of it in percentages instead but (in family 1 for example) 2/5 is 40% and 3/5 is 60% so that doesn't work with the dominant-recessive punnett square where each trait is 25%. so either I'm wrong about the inheritance pattern or I'm just full on . someone please help, i don't think I've ever been this confused in bio.
In complete dominance, heter0zyg0us individuals carry both alleles -dominant and recessive- but only express the dominant phentoype. Cross 1: Nn x nn. Cross 2: NN x nn
What is complete dominance?When the dominant allele completely masks the recessive allele, we talk about complete dominance.
This is the case of individuals that are heter0zyg0us for a particular gene and express the dominant trait. The dominant allele is hiding the expression of the recessive allele.
What is a punnett square?The Punnett square is a representation that shows the different types of gamete combinations according to the alleles involved in a cross.
Punnett square shows the probabilities of getting offspring with different genotypes and their consequent phenotypes.
So, according to the provided data,
Cross 1: gray fur x black fur
F1) 3 gray fur: 2 black fur
Cross 2: gray fur x black furF1) 0 gray fur: 5 black fur
By looking at the phenotype of progeny produced by family 2, and assuming complete dominance, we can infere that black is the dominant phenotype. Why is that? because when you crossed a gray animal with a black animal and the whole progeny is black.
So, assuming a diallelic gene coding for the fur color, we will name
N to the dominant allele that codes for blackn to the recessive allele that codes for gray.Possible genotypes and phenotypes
NN ⇒ Black fur ⇒ dominant phentoypeNn ⇒ Black fur ⇒ dominant phentoypenn ⇒ Grey fur ⇒ recessive phentoypeHere what you need to analyze is which phentoypes appear among the progeny and their frequencies to get to interprete the parents' genotype.
If both parents are h0m0zyg0us dominant (NN x NN), the whole progeny expresses the dominant trait (100% NN)If one parent is h0m0zyg0us dominant and the other one heter0zyg0us (NN x Nn), the whole progeny expresses the dominant trait (50%NN and 50%Nn).If one parent is h0m0zyg0us dominant and the other one h0m0zyg0us recessive (NN x nn), the whole progeny expresses the dominant trait (100% Nn).If both parents are heter0zyg0us (Nn x Nn), the offspring will express both phenotypes in a ratio 3:1 (25% NN + 50% Nn and 25% nn).If one parent is h0m0zyg0us recessive and the other one heter0zyg0us (nn x Nn), the offspring will express both phenotypes in a ratio 1:1 (50% Nn and 50% nn).If both parents are h0m0zyg0us recessive (nn x nn), the whole progeny will express the recessive trait (100% nn).Now let us analyze the crosses,
Cross 1: gray fur x black furF1) 3 gray fur: 2 black fur
You crossed a black animal with a gray animal and the offspring expresses both phenotypes. So the black animal (dominant phenotype) must be heter0zyg0us for coat color.
Parents' phenotype) gray and black
Parentals) nn x Nn
Alleles in Gametes) n n N n
Punnett square) N n
n Nn nn
n Nn nn
F1) Genotype
1/2 = 50% of the progeny is expected to be heter0zyg0us, Nn
1/2 = 50% of the progeny is expected to be h0m0zyg0us recessive nn
Phenotype
1/2 = 50% of the progeny is expected to be black -Nn-
1/2 = 50% of the progeny is expected to be gray -nn-
Cross 2: gray fur x black furF1) 0 gray fur: 5 black fur
You crossed a black animal with a gray animal and the offspring expresses only the dominant phenotypes. So the black animal must be h0m0zyg0us dominant for coat color.
Parents' phenotype) gray and black
Parentals) nn x NN
Alleles in Gametes) n n N N
Punnett square) N N

n Nn Nn
F1) Genotype
100% of the progeny is expected to be heter0zyg0us, Nn
Phenotype
100% of the progeny is expected to be black -Nn-
Remember that the Punnett square does not give you information about the number of individuals that can be produced. It just provide information about probabilities of getting individuals with certain genotype of phenotype and their frequencies.

The sciatic nerve extends from the lower spinal cord to the foot. If a person's sciatic nerve is 0.914 m in length and the speed of an action potential is 107 m/s, how long will it take for a nerve impulse to travel the full distance of this nerve?
Answer:
0.0085420560747664 Seconds
Explanation:
0.914 ÷ 107 = 0.0085420560747664
The time that the nerve will take for a nerve impulse to travel the full distance of this nerve is 0.00854 seconds.
What is a sciatic nerve?Sciatica is caused by a pinched sciatic nerve. The most common cause is a herniated disc in the spine or an overgrowth of bone, known as bone spurs, on the spinal bones.
A tumor can occasionally impose pressure on a nerve. A condition, such as diabetes, can also harm the nerve. The speed of something is how fast the object is moving. It is calculated by the distance divivded by time.
Given, the length of the sciatic nerve is 0.914 m
The speed of an action potential is 107 m/s.
The length is divided by the speed
0.914 / 107 = 0.00854 sec.
Therefore, the full distance of this nerve is 0.00854 seconds.
