The human genome is composed of millions of molecules of DNA perfectly packaged into 23 chromosomes. Each human is the result of a combination of the same four nucleotides, yet every single one is unique. Perhaps, this is due to the slight variation in each human’s DNA, or maybe the explanation lies in a person’s upbringing. The purpose of studying human development is to understand why people change by applying the scientific method to existing theories, which provide the basis for…

ANALYSIS AND DESIGN OF CUCKOO ALGORITHM Cuckoo search (CS) is an optimization algorithm developed by Xin-she Yang and Suash Deb in 2009. It was inspired by the obligate brood parasitism of some cuckoo species by laying their eggs in the nests of other host birds (of other species). Some host birds can engage direct conflict with the intruding cuckoos. For example, if a host bird discovers the eggs are not their own, it will either throw these alien eggs away or simply abandon its nest and build…

It is within human nature to strive for perfection. To be the best we can be, and now humans are on the brink of discovering how to finally reach this “perfection” we desire through genetically modifying fetuses or in other words creating a designer baby. However, should we really turn to designer babies in our search for perfection? In my opinion I do not believe we should because there are so many unforeseen consequences of designer babies that we cannot comprehend. We may come across bacteria…

B) Blackthorn (Prunus spinosa) Active components of the plant are believed to be polyphenols, including flavonoids, A-type proanthocyanidins, anthocyanins, coumarins, and phenolic acids, forming unique and diversified profiles in particular organs, among which the flowers are the least (Owczarek et al., 2017). This work is the first comprehensive phytochemical and activity study of the flower extracts of P. spinosa. (Phenolic compounds of blackthorn (Prunus spinosa L.) and influence of in…

1ml per sample. The samples were incubated at 4⁰C overnight. The following day, the samples were washed with DPBS at 4⁰C and then washed with 2ml 1 perm buffer twice. Anti-mouse Foxp3- PE Ab was added in a 1:100 dilution for 30 mins at 4⁰C. The samples were washed with perm buffer and resuspend in DPBS for flow cytometry analysis.

The theory of evolution has been argued over for many years. This theory states that all living things have a common ancestor and each living organism has adapted and evolved through natural selection. Many people disagree with this theory because they feel that the theory of evolution has removed God from his rightful place. These people who did not believe in evolution came up with creationism, which says the universe and living organisms were created by a celestial being rather than natural…

Alex and Me is a book written by Irene M. Pepperberg, a scientist who mainly focusses on animal behavior, animal cognition, and comparative psychology. Pepperberg was born on April 1, 1949 in Brooklyn, New York. She received her M.A. and Ph.D. from Harvard University and her B.S. from Massachusetts Institute of Technology. After this, she became a psychology professor at Brandeis University, where she also became involved in wildlife conservation. Alex and Me is about a parrot who becomes very…

This gene regulates serotonin, which affects your mood, in the brain. However, a certain version of this gene does not have the ability to respond to the calming effects of serotonin. Astonishingly, this specific version is found in several serial killers, which was discovered from Fallon’s study. Moreover, this proves that it is likely that serial killers are created based on several biological factors that are evident in the gene makeup of fellow killers. In addition…

There are many diseases in the world that are deadly but acted as an evolutionary advantage in the past to help us, humans survive, reproduce and evolve into the species that we are now. For example, in Survival of the Sickest by Doctor Sharon Moalem and Jonathan Prince, it discusses diseases such as hemochromatosis, diabetes, and favism or glucose 6 phosphate dehydrogenase (G6PD) deficiency which all are deadly but helped humans survive in the past. Hemochromatosis is an inherent…

Yasmin Mendoza 9-26-17 5th hour Process Paper What is an Ant Farm? An Ant Farm is known as a project to study an ant colony and the behavior each ant carries. There are many ways to start one of these colonies and many ways to maintain them. This could be a really cool science project or even a type of “pet” to have. The first thing you need is a formicarium, which is a type of transparent box thin enough to study the ants and for the ants to make their tunnels. You need three types of dirt…
