I n conclusion‚ the experiment was about the effect of soapy water on plants. The hypothesis was‚ “If plant A is given 10 ml of plain tap water every other day for two weeks and plant B is given 10 ml of soapy water (5 ml softsoap and 5 ml plain water) for the same amount of time then‚ plant A will grow at least 3.0 cm taller than plant B.” The Hypothesis was supported. Plant A grew 13.6 cm while Plant B grew only 5.2 cm. The Independent variable was water‚ food‚ plastic cup‚ sunlight and soapy

Effects of Plant Nutrient Deficiency Abstract This experiment aimed to determine the effects of nutrient deficiency on plants. This was done by examining tomato plants grown in a medium that contained all the nutrients needed to survive and comparing those results to plants that were grown in nutrient deficient mediums. The biomass and standard chlorophyll content were the focus of the experiment. The biomass was measured by taking the mass of the plant. The standard chlorophyll content was

EFFECTS OF NITROGEN FIXING PEA PLANTS (Pisum sativum) ON GROWTH OF CORN (Zea mays) Introduction Interactions among plant species‚ particularly negative ones‚ have been a concern in agriculture (Levene 1926‚ Russell 1961). Novoa (1981) suggested that it would be advantageous to rotate certain crops by season‚ grow certain crops together‚ or avoid growing certain crops on the same land. Observations indicated that some crops require specific types of nutrients in contrast to other crop

The factors affecting plant yield: light level Abstract The factors affecting Zea mays‚ maize (C4) and Pisum sativa‚ or pea (C3) plant yield and growth patterns placed under shade and full sunlight were investigated. 20 plantlets placed into four vermiculite compost pots (5 from each plantlet) and submitted to fertilizer or no fertilizer. And after 4 weeks the results showed that maize grown in light with no fertilizer had a higher relative growth rate and root to shoot ratio indicating the allocation

In his book Caffeine Blues a famous researcher‚ health educator‚ and clinical nutritionist Stephen Cherniske compares remaining healthy and strong throughout life to a battle. “Caffeine is the Trojan horse. It looks like a gift but instead delivers adrenalin stress‚ low blood sugar‚ mood and energy swings‚ fatigue‚ depression‚ malnutrition‚ and disturbed sleep”. Although caffeine is considered a mild drug‚ the consequences of caffeine addiction are rather severe and include physical and mental health

It increases plant production by as much as 106% as long as the plants are getting the required amount of water for normal plant growth. Super phosphate does little if nothing if there is no rain or agitation so farms living in low rain fall areas tend to use other non water depended fertilizer. It was really bought to the

Caffeine and Coffee Consumption Maddie Schierbeek Psychology 7th block Why do so many people‚ especially high school students consume so much caffeine? Perhaps 70-minute classes are too much to handle. Maybe the AP course load is overwhelming. Or perhaps problems at home cause a lack of sleep. Everyone has their reasons. On the other hand‚ there may be a scientific reasoning behind it. Caffeine highs are followed by caffeine lows. This cycle results in a need for caffeine: addiction. Researchers
