Abstract Four pure, unidentified cultures of (gram positive cocci) bacteria, labelled A-D were cultured on various agar media. Also an API test was simulated to identify another unidentified bacterium. Identification of bacteria is important when choosing an effective treatment for a microbial-causing illness. This experiment …

The term ‘antibiotics’ refers to substances that kill bacteria or prevent their growth. Antibiotics are natural substances that are released by bacteria and fungi into their environment to fight other organisms. The use of antibiotics by organisms therefore represents chemical warfare on a microscopic scale. …

Stomata are tiny pores found on the epidermis of the leaf, surrounded by guard cells. [1] Their main function is gas exchange [1] for photosynthesis and respiration. The development of stomata on the leaves of a plant is determined by interaction between different genes and …

The human life cycle is essential to the world’s population. It allows individuals to create families that can change society in multiple ways and all those individuals that has the capacity to change the world has a mother. Every soon to be mother wants an …

The respiratory system helps to provide the body with the necessary gas exchanges needed for living cells. This exchange helps with other major body systems and functions within the body such as the circulatory system and the process of cellular metabolism. The respiratory system consists …

Bacteriophages are actually viruses highly specialized to attack bacterial cells while doing no harm to animal cells. When a phage discovers a bacterium to which it possesses the correct key—that is, suitable receptors on the bacterial cell to which the phage can attach its tentacle-like …

The probable reason for the tinted brown shade in the human epithelial DNA and not the strawberry DNA is that human epithelial DNA is extracted from one’s mouth in which there can be many germs that could change the color of the original DNA. Furthermore, …
