Answer:
option B
Explanation:
there are 22 pair of autosome and 2 pair of sex chromosome
Correct sequence of sperm-transporting tubules that transport spermatozoa to the epididymis is Seminiferous Tubules---> Rete Testis---> Vasa Efferentia----> Epididymis
Spermatozoa is the sperm that is formed from a spermatid after Spermiogenesis. It is released into the lumen of seminiferous tubules.
Seminiferous Tubules is present in the testis of human body.
Sperm transporting tubules are:
The sperm passes through the seminiferous tubule into Rete testis.
Rete testis is a network of tubules that form a link between seminiferous tubule and Vasa Efferentia.
Vasa Efferentia connects Rete testis to Epididymis. It makes a pathway for the sperm transportation.
Epididymis is the region where the transported sperm from Vasa Efferentia reach. It stores the sperm until they are functionally matured enough to carry out the fertilisation in the human female body.
Hence, the pathway is Seminiferous Tubules---> Rete Testis---> Vasa Efferentia----> Epididymis

The answer is:
<span>processing of exons in mRNA that results in a single gene coding for multiple proteins.
</span>
RNA splicing is an important stage in gene transcription. mRNA transfers the information from DNA to proteins. In many cases, this process creates multiple proteins from the same gene by varying the exon composition. This is called alternative splicing and can happen because exons are extended or skipped, or introns can be retained instead of being removed.
<span>The experimental evidence that leads </span><span>scientists to believe that only quantized electronic energy states exist in atoms </span>was the Niels Bohr experiment on Hydrogen gas. The quantized model for electron orbits in atoms that effectively explained the spectroscopic behavior of the atoms. Each line in the spectrum corresponds to one exact frequency of light emitted by the atom.
Cells do contain sub structures called organelles. Each organelle within the cell performs specific functions. According to cell theory, cells are the basic units of life.
Cells do not come together to form molecules, because molecules are significantly smaller than cells and are present inside of the cell’s various structures.
