Carbohydrates are the most abundant biomolecules and serve as energy forces, fuel metabolic intermediates and have major structural roles in plants and insects. Carbohydrates are polyhydroxy aldehydes or ketones with the empirical formula (CH2O)n. Monosaccharides or simple sugars consist of a single polyhydroxy aldehyde or ketone unit with at least one asymmetric carbon. Monosaccharides with five or more carbon atoms can exist in closed five-membered ring (furanose) or six-membered ring (pyranose)

Without the sun’s energy, all living things would die. Especially in the tropical rainforest the sun is essential for survival. Without the sun, plants would not survive and life as we know it would cease to exist. (Choi, 2012). As an alternate form of energy, plants will use the sun, chlorophyll, water, carbon dioxide and nutrients in order to manufacturer glucose. (UCSB Science Line). Tropical rainforests can be found in Africa, Asia, Australia and Central and South America. The Amazon

Question 1 List and provide a brief discussion of the seven categories of toxic responses that a biological system may have. . There are seven categories of toxic responses: • Acute toxicity. This category is related to the immediate toxic responses that every biological system may have. This exposure of toxic substances for shorter duration and the diverse effect is high • Sub-chronic toxicity. This group results from exposure that is recurring numerous times. It is an ordinary human exposure

‘Not only do Prokaryotes have a wide range of metabolic activities crucial for maintaining the biosphere, they also exert significant impacts on human life’ discuss this statement fully using named examples. Prokaryotes are unicellular microorganisms without a nucleus; they are divided into two groups’ Eubacteria and Archaebacteria. These microorganisms are very small and invisible and are known as the most dominant species on the earth’s biosphere as they are found almost everywhere on earth

Unit 1.3 Task 1a Cell membrane – The cell membrane is a biological membrane that’s job is to separate the interior of a cell from all of the cells in the outside environment. It is selectively permeable to ions and organic molecules. It also controls the movement of substances in and out of a cell. The function of the cell membrane is to protect the cell from its surroundings. The cell membrane can be found in plants and animal cells. Cell wall – The cell wall is a very flexible but tough layer that

stronger and more durable. With technology expanding, nanotechnology can revolutionize the medical industry as well like never before. Nanotechnology- based drug delivery is being seen as a revolution in protein and gene therapy, for delivering biomolecules such as DNA and siRNA, enabling researchers to overcome several hurdles that are found in these therapies using conventional delivery systems (India Pharma News). The drugs would inter through a nanoparticle that is capable of targeting specific

Biomimicry or biomimetics is the examination of nature, its models, systems, processes, and elements to emulate or take inspiration from in order to solve human problems.[1] The term biomimicry and biomimetics come from the Greek words bios, meaning life, and mimesis, meaning to imitate. Similar terms include bionics.[2] Over the last 3.6 billion years,[3] nature has gone through a process of trial and error to refine the living organisms, processes, and materials on planet Earth. The emerging field

Nowadays, forensic phenotyping, aiming to infer the unknown sample donor’s appearance from DNA, is expected to reduce the number of potential suspects (4, 5). To date, the most well studied externally visible characteristic (EVC) markers are the single nucleotide polymorphism (SNP) markers associated with pigmentation, e. g., the variations in the coloration of the iris, hair, and skin (6–8). However, such pigmentation markers may not be useful in certain populations such as Asians and Africans with
