The video was about two couples who were trying to produce a baby. The video focus on how the sperm reaches the ovaries. Part One: We was introduce to Glen. Every heart beat Glen has 1000 sperm are producing in the testis. Sperm are free-living cells constantly moving. Sperm is one five hundred milliliter long. The testis, where sperm is made, is a round, elongated structure and has a series of tubules. In the video, the “sperm people” in white clothing where in a building waiting. This…

The slide used during the Microscope Lab was a wet-mount slide which was used in order to view the specimens from the microscope. A wet-mount is a method for preparing specimens to view using a microscope. A myriad of specimens look better when placed in a drop of water on the microscope slide. The water supports the sample and fills the space between the coverslip and the slide. This allows light to pass easily through the slide, the sample, and the coverslip. Scientists use the wet-mount…

Human development has been regarded as one of the most highly controversial topics in the world of psychology. Nature vs Nurture is labeled as a debate. Nature and nurture has to do with behavior, feelings, personality, and intelligence. Many that believe we inherit our personalities, feelings, behavior and intelligence are on the nature side. Others who think its environmental influenced are on the nurture side. Nature and nurture goes hand and hand in the development of the human process.…

Trisomy X Trisomy x syndrome, also known as triple x and 47xxx, is characterized by the presence of an extra x chromosome in each cell of a female. Three x chromosomes are present, rather than a normal pair in the nuclei of body cells. The first published report of a women with triple x syndrome was Patricia A. Jacobs at Western General Hospital in Edinburg, Scotland, in 1959. The condition occurs in about 1 in 1,000 newborn girls. Five to 10 girls with triple x syndrome are born in the united…

genetic information in cells and some viruses, consisting of two long chains of nucleotides twisted into a double helix and joined by hydrogen bonds between the complementary bases adenine and thymine or cytosine and guanine. DNA sequences are replicated by the cell prior to cell division and may include genes, intergenic spacers, and regions that bind to regulatory proteins. DNA A. adenine T. thymine C. cytosine G. guanine What is RNA ? A nucleic acid present in all living cells and many…

Introduction Background While the clinical validity of genetic tests is growing, there emerges a concern that the disclosure of individuals’ genetic test results could lead to discrimination by health insurers and employers (Hudson et al., 2008). Federal legislation addressed the protection of individuals’ genetic information by passing the Genetic Information Nondiscrimination Act (GINA) in May 2008. The law prohibits health insurers and employers from using an individual’s genetic…

After looking at the results, there seemed to be a match between DNA found at the crime scene and DNA from one of the suspects. DNA from the crime scene with enzyme one matched closely with DNA from suspect two that was with enzyme one. Along with that match, the DNA from the crime scene with enzyme two was matched closely with DNA from suspect two with enzyme two. Because there were close matches to the DNA found at the crime scene, does not necessarily mean that the suspect is guilty. There…

not surrounded by a membrane but are located in an area of the cell called the centrosome. The centriole has its appearance and structure the way it is because its arrangements must be a circular and the triplet fibers that it’s made out of will eventually create a shape that is similar to a barrel when it it is arranged. One of their main function is to contribute/help with processes that involve cellular activities. One example of cell division where centriole plays a role in mitosis where…

restored. Did you know there are approximately 100,000-150,000 pieces of hair growing out of your scalp. Scientists have discovered 2 things why hair is so thick on your head. 1 thickness is made from Keratin the protein which is dead cells lifted above and new cells created below. Secondly, the structure which operate hair growth are hair follicles-This is how your hair grows constantly beginning for when you were born till you die.…

Aspergillus nidulans: One of the lesser known pathogen of the aspergilli group, A. nidulans is a model filamentous fungus widely used for studying eukaryotic cell biology (Galagan et al., 2005). A. nidulans possesses a phospholipid-hydrolyzing novel cPLA2 protein, PlaA, which shows maximum similarity to mammalian-type cPLA2 proteins (α, β, γ) (Hong et al., 2005). Like the three isoforms of human cPLA2 proteins, A. nidulans PlaA also consists of two separate catalytic domainsA and B, and…
