Biological pigment

kingdom (kingdom plantae) contains eukaryotic, mutli-cellular plants. This kingdom includes a wide variety of plants such as shrubs, trees and herbs. All plants make their own food through the process of photosynthesis, as they contain chlorophyll pigment. The last kingdom is the metazoa kingdom (kingdom animalia), and consists of heterotrophic, eukaryotic, multi-cellular…

For what do we use microscopes? Do we need them for any types of jobs? Microscopes are very helpful for many jobs such as doctors, jewellers, Environmental and Geoscientists, Forensic Science Technicians, Biological scientists and many more. Microscopes help us see things that we are not able to see with the bare eye such as cells, bacteria and much more. For this essay I will be mainly focusing on how microscopes help doctors in their jobs. I will be talking about how microscopes have helped…

They are found in the Basal Layer of the Stratified Epithelium, where they multiply by dividing. Keratinocytes over time become flatter, lose their nuclei and die. The second cell type is called the Melanocytes, which produces the skin darkening pigment melanin. The cell is located in the Basal Layer of the Epidermis, the Melanosomes are relocated to the Epidermal cells. Which then makes pigmentation of the Epidermis. Melanin is responsible for different skin colours. The Merkel Cell is in the…

As macromolecular machines, enzymes conduct their designated work in the confined and crowded spaces inside living cells. How does a protein work in such a condition? Functions of proteins are strongly dependent on their structural stability and dynamics while the (macro) molecular interactions are arguably affected by the complexity and diversity of their environments. To date, two interrelated cellular conditions — ‘macromolecular crowding’ resulted from the effect of volume exclusion by…

Q1. “Take a close look at Beau’s fur. Use a qualitative data to describe it.” Q2. “What is hair made up of? How much of it is protein, carbohydrate, nucleic acids, and lipids?” Q3. “Take a close look at Beau’s fur. Use qualitative data to describe it. How has Beau’s coat changed between puppyhood and adolescent?” Q4. “What do you think is happening to Beau’s coat change? What are your initial hypothesis?” Q5. “Based on what you know now about Beau’s parents and littermates, what do you think is…

delivery systems through the fabrication of nanostructures capable of encapsulating and delivering small molecules. Nanoparticles have small sizes ranging from 1-200 nm which can improve the bioavailability of therapeutic agents and pass through biological barriers of the eye[8]. Another important characteristic of nanoparticles is that they can be fabricated bespoke through chemical processes. For examples, particulate nanocarrier-based delivery systems have improved the pharmacokinetic and…

ACC deaminase in the developing plant’s roots to lessen the level of ethylene (Dey et al. 2004), producing phytohormones (Mishra et al. 2010) and biological N2 fixation (Ardakani et al. 2010). The plants also exhibit antagonistic activity against phytopathogenic microorganisms by producing siderophores, chitinases, b-1,3-glucanase, fluorescent pigment, antibiotics, antifungal metabolites, and/or lytic enzymes, increasing plant nutrients availability via systemic resistance induction…

Leonardo Da Vinci’s Last Supper (1495-1498) was painted on the north wall of the refractory of Santa Monica delle Frazie in Milan. The commission was to a Dominican monastery for their dining hall, and appropriately the Last Supper focuses on the announcement of the betrayal in the passion of Christ. Multiple other scenes were incorporated such as signs of the sacrament where Christ, for instance appears to point at the bread and wine on the table before him . Leonardo used both the power of art…

Over the past few decades, increasing research and development efforts toward value addition and efficient utilization of nutritionally rich agro-industrial residues have been gaining attention around the world. Several industrial residues, such as whey, sugar beet pulp, cassava bagasse, apple pomace, citrus waste, coffee pulp/husk, etc., have been studied as model system. They are either used as microbial substrates in fermentation or are subjected to the extraction of bioactive molecules1-4.…

Discussion: The isolate studied was tested for innate antibiotic function on the following media: AC, LB, and 10% TSA. The ESKAPE relative strain that presented a response to the isolate was B.subtilis. In all cases except for that of LB, the isolate showed antibiotic qualities towards B.subtilis by presenting a zone of clearance on AC and 10% TSA media. This behavior is shown in Figures 4, 5, and 6.In the case with LB, B.subtilis inhibited the growth of the isolate as depicted by the empty…
