Where do sperm go after leaving the epididymis?
OA. Ejaculatory duct
OB. Seminiferous tubules
C. Vas deferens
OD. Urethra

Answers

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.

Is a law a theory or is a theory a proposed law

Answers

Answer:

Theory is a proposed law.

Explanation:

A proposed law is a law that has not yet been approved; a speculation made by an individual that has not yet been proven as a real thing. For example, I say that ice cream is now free for all, and that would be a completely proposed law since no one has approved that but me.

Answer:

Neither

Explanation:

A law is something in science that can be proved through experimenting. A law does not attempt to explain why something is the way it is, it only states it.A theory is an idea that has a large amount of scientific data backing it and is the accepted answer by most scientists, but there is no way to experiment on a scientific theory. A theory will never be able to become a law. A theory explains what it is describing.

An example of a law is the law of conservation of energy, which has to do with how energy is used. Scientific experiments can be done to observe energy.

An example of a scientific theory is the theory of natural selection. Based off of data and observation, the theory of natural selection has been formulated, and the theory of natural selection explains why.

Puppies increase in size as their cells grow and divide. Almost all cells complete a full cell cycle that includes interphase and cell division. In interphase, cells serve their specialized functions, grow, and copy their genetic material. Mitosis is the first stage of cell division, in which the copied chromosomes are separated into two new nuclei. Then in cytokinesis the cell divides into two daughter cells. If no mutations or errors occur, the genetic material in each daughter cell is identical to what was in the original cell.

Now that you have completed this lesson, you should be able to:

describe the stages of the cell cycle
use a model to illustrate the role of cellular division in the formation of new cells
describe the structure of a chromosome
follow chromosomes through the processes of mitosis and cytokinesis

Answers

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 fur

F1) 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 phentoype

Here 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 fur

F1) 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 fur

F1) 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

                            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.
