The Effect of Watering on the Plant Growth 1. Problem/Question: Sarah observes the small garden in their house. She ask her mother why are the plants needed water but it has fertilized already. Their plants aren’t grow . So she decided to experiment on what is the effect of watering on plant growth. 2. Observation/Research: She water them every day‚ they have good soil‚ and they’re in the shade. 3. Formulate a Hypothesis: Sarah think plants will grow better if they’re in the sun

About 70% of the Indian population lives in more than 550‚000 villages. The balance stays in more than 200 towns and cities. India is expected to surpass China in total population by 2030 (five years earlier than previously estimated).

2. THEORY OF DEMAND AND SUPPLY: THEORY OF DEMAND: Demand refers to the quantity of a product that consumers are willing and able to buy at a particular price and over a given period of time. The law of demand states that more is bought at a lower price than at a higher price. In other words‚ the law of demand postulates an inverse relationship between the price and quantity demanded of a commodity‚ all other factors affecting demand remain constant (ceteris paribus). A market demand curve

Temperature effects on the growth of microorganisms Introduction: The purpose of this experiment was to determine the effects that temperature has on three different organisms. Temperature is one of the most important environmental factors affecting growth and survival of microorganisms². The three organisms used where Escherichia coli‚ Pseudomonas fluorescens‚ and Bacillus stearothermophilis. Most bacteria grow within a particular temperature range. The minimum growth temperature is

PROCEDURE: Part A (Effect of temperature on growth) 1) 15 tubes of glucose broth are provided and one set of 3 tubes are inoculated with each of the following cultures; Escherichia coli‚ Pseudomonas fluorescens‚ Micrococcus luteus and Saccharomyces cerevisiae. The last served as control. 2) One of the three tube of each culture is incubated at each of the following temperature: * 4°C * 37°C * 55°C 3) All the tubes are incubated within 5 minutes after inoculating.

The Effects of Antibiotics on Bacterial Growth Biology II 1996 Bacteria are the most common and ancient microorganisms on earth. Most bacteria are microscopic‚ measuring 1 micron in length. However‚ colonies of bacteria grown in a laboratory petri dish can be seen with the unaided eye. There are many divisions and classifications of bacteria that assist in identifying them. The first two types of bacteria are archaebacteria and eubacteria. Both groups have common ancestors dating to more

In Japan‚ fish is the primary “meat” to eat‚ which means not only do they keep their cholesterol lower‚ but they also get healthy fish oils‚ too. Now‚ there’s probably something to be said about the nasty stuff that can come with fish (i.e. mercury)‚ but no matter what you eat you’re going to be getting something “fun.” Less Milk‚ Butter‚ Dairy: Most Japanese people are lactose intolerant.

Aging Population Effects on Health Care Health care is a fast evolving field with advancements of technology and treatment options growing every day. The delivery of care has grown and often shifts direction over the years to accommodate changing population demographics and needs of patients. Many factors play a part in the role of health care and medical treatment‚ one of those factors being population demographic changes. When the demographics of a population change it can cause adverse effects
