Answer: a. vas deferens
Explanation:
The spermatic cord refers to the cord or tube which is supplied with the collection of the nerves, ducts and vessels that run to the testes or from the testes. These are surrounded by the fascia.
The spermatic cord contains the testicular artery, plexus veins and vas deferens. The other structures of the cord includes the cremasteric artery, sympathetic nerves and lymphatic supply from the epididymis and testis.
Answer:
Here's a couple:
1)Different types of chromosomes.
2)Different diseases or health problems
3) Cognitive or behavioral differences
4)Different genitalia

Hope this helps a little! :)
The possible result of the founder effect would be loss of genetic variation. The reason why this is so is because by definition, the founder effect is often considered to be the cause for a essened genetic variation in a specie or a certain area where organisms thrive.
Evolution is the gradual process resulting in the changes in the genetic material of a population over generations. The mechanism that Darwin proposed for evolution is the process of natural selection. Natural selection is the key mechanism of evolution which increases the frequency of advantageous alleles in a population. Due to the limited resources in nature, organism with heritable traits favoring their survival and reproduction produce more offspring. It causes the population to become adapted to their environment and results in organisms with better survival ability and reproduction. These traits become heritable due to the reproductive advantage and are passed from the parents to the offspring. Over generations, the advantageous heritable trait becomes dominant in the population. It is responsible for the variation in the gene pool of the population which increases their fitness.
Answer:
Cell differentiation is the process by which dividing cells change their function. DNA is essential in gene expression, which gives the ability of cells that are specializing to be able to adequately perform the role they are trying to carry out. It is generally understand that all the cells in our body contain the same DNA, yet they carry out different functions. The key is understanding that specific parts/combinations of the genome are activated which changes the function and shape of the cell. Additionally, if the DNA is damaged or mutated in certain areas of the chromosome, it can cause certain differentiated cells to not function properly.
