Kiecolt-Glaser (1984) carried out a natural experiment investigating whether the stress of short-term stressors had an effect on immune system functioning

show that music possesses properties that affect the growth rate of plants in different ways. These properties may be the wavelength of the music‚ its frequency or even its tempo. According to a study conducted by Margaret E. Collins and John E. K. Foreman‚ entitled The Effect of Sound on the growth rate of plants (2001)‚ plants growth is directly affected by sounds of varying frequencies. They observed that when plants are exposed to pure tones‚ it affects the growth of the plant. This was due to

Starch Diffusion in a Caterpillar’s Digestive Tract The object of this particular experiment is to gain knowledge on diffusion across a plasma membrane‚ which is selectively permeable. Diffusion is the movement of a substance from a region of high concentration to lower concentration. Experiment 2 was performed to see how the substance’s‚ starch‚ and diffusion process across a plasma membrane is affected by amylase. We prepared a simulated digestive tract of a caterpillar‚ as the plasma membrane‚ to

ICO2: Causes and spread of infection 1.1 Bactetria are: Bacteria are organisms made up of just one cell. They are capable of multiplying by themselves‚ as they have the power to divide into different shapes. Their shapes vary‚ and that’s how they are used to separate them into groups. Usually a few micrometres in length. Bacteria are present in most surroundings on the planet‚ growing in soil‚ acidic hot springs‚ radioactive waste‚ water‚ and deep in the Earth’s crust‚ as well as in organic
