Language development is an objective indicator of developmental and cognitive skills in children. It is also one of the fundamental pillars for a child to acquire autonomy and be able to adapt to social and academic situations. A language delay (including both verbal and non-verbal skills) is an indicator that some aspect of development in young children is not going well. Language delays may be primarily due to four causes: hearing problems, neurodevelopmental conditions, such as the risk of having...

Introduction Cellular energetics are types of ways in which cells, whether eukaryotes or prokaryotes, obtain energy to drive functions in a cell. Cellular respiration is one type, for eukaryotes, that uses reactants like sugar, such as glucose, and oxygen to create products of carbon dioxide, water, and energy in the form of ATP (Urry et al 2020). The purpose of this process is to create energy for the cellâs functions, water for the body, and carbon dioxide that is useful...

Mastering your native language is somehow natural but mastering two languages simultaneously is a rather satisfying condition which is called bilingualism. Bilinguals are those who understand and speak 2 languages. The term bilingualism can refer to both individuals and the entire society. In Armenia, it refers to individuals because our clear language is Armenian. However an Armenian can also master 2 languages due to his articulation abilities, environment, diligence, love towards learning new languages and of course linguistic abilities. In...

Introduction The reason I picked this question is because the worldâs current climate crisis has been a very topical and controversial subject amongst my peers. Vegetarianism was the solution that came up the most, so I decided to dig a little deeper into it and see if it was really true. The planet is in a dire condition. Carbon emissions have increased drastically since 1970 by more or less 90%. There has been an immense influx of natural disasters, a...

Introduction The hypothesis for this experiment is the more concentrated a given solution is, the more light is absorbed. Through the results recorded and calculated from the practical, the hypothesis will be proved or disproved. Beerâs Law states that absorbance and concentration are directly proportional. âThe Beer-Lambert equation shows that if the concentration of absorber doubles, the absorbance of the solution also doubles.â (Lewis & Evans, 2011). Through this experiment, this statement will be tested. Experimentally this conclusion is only...

Introduction Natural Selection has a great effect on species in different environments. Different species can inherit mutations, some may be good, and some may be bad for the individual(McGraw-Hill Ryerson. 2010). It is also the reason for evolution(Grabianowski, 2018). Natural Selection is the leading factor in deciding which species will live and reproduce, and which ones will die out(Brain, 2019). This lab will simulate the effects of Natural Selection on a population of bead bugs. The dependent variable is the...

Introduction Human achieves language by being in a culture, it is passed down to generation and the next. This is what Yule (2010.p.14) described as cultural transmission. Humans do not inherit language they achieve them which means that language is not transferred through genes of the parents it is obtained by being with other speakers. Furthermore, Yule states that a human child is not a fully articulate language-user, the human child only starts being an active language-user during what Yule...

Many believe that DNA is the silver bullet in a crime scene investigation, to which I strongly disagree. Quoting Chris Alpen, âDNA can never replace a thoughtful, creative detective with the right resourcesâ, and that âtechnology is ultimately a system run by humans where mistakes can and will be made, regardless of how advanced it is.â DNA is powerful in its ability to identify a person; ÂŹits discovery can determine the innocence or guilt of a suspect.

Phrenology was a pseudoscience that aimed to study the size and shapes of skulls in order to determine oneâs mental abilities, or lack thereof (Real Archaeology, 2017). This âscienceâ was welcomed in the early 1800âs but it has since been refused by most scientists for at least the past 50 or 60 years. Even though we may reject it now, phrenology was used to confirm many racist beliefs in the 1800s and those beliefs are embedded in our society. There...

Life is a DNA driven programme and death results from its technical failure. Protein and DNA were evolved naturally from the gas present in the environment of the primitive world. It was the effect of high voltage thunderbolts and asteroid hits on the surface of the earth. Millions of years ago passage of the high voltage energy across the environmental gas created protein and DNA. Origin and evolution of DNA and DNA replication mechanism are not yet fully known, but...

Introduction Starch is a common polysaccharide, made up of glucose monomers (Serrano and Peralta, 2015). Pancreatic amylase is often the enzyme involved in the digestion of starch (Chegeni et al., 2018). Amylase is also an exoenzyme and facilitates the digestion of dietary carbohydrates (Nifty et al., 2019). Amylase causes conformational changes in starch, resulting in a reduced viscosity, and increased solubility (Vafina et al., 2018) Amylase is often used in the food industry, in the health field, as well as...
