That was fast: The influence of light intensity on the growth and development of Wisconsin Fast Plants Introduction It is common knowledge that plants need light to grow and develop. This is done by the conversion of light energy into usable sugars during photosynthesis. Light absorbing molecules‚ known as pigments‚ absorb only specific wavelengths of visible light‚ mostly blue and red wavelengths (1). Whatever wavelength isn’t absorbed is reflected and the reflection is the color of plant we

between the average winter temperature over the past 10 years and the current average winter temperature. If the current price of home heating oil is $1.20‚ the current price of natural gas is $2.00‚ and the average winter temperature this year is 40 degrees compared to 28 degrees over the past 10 years. A. What is the quantity of home heating oil demanded? 6.6 units B. How much did change in winter temperature effect demand in comparison to the average winter temperature? 12 units C.

experiment was to determine the effect of temperature on the rate of movement of Porcellio scaber. Our prediction was that P. scaber would have faster rates of movement in hotter temperatures. We expected this response as P. scaber is an ectotherm. Hence‚ its body temperature is directly determined by the temperature of its environment (Mellanby 1939). Løkke and van Gestel (1998) stated that the rate of the metabolism is controlled by the environmental temperature for ectotherms. As seen by Wieser

Optic nerve sheath diameter (ONSD) The anatomy of the optic nerve sheath : The intraorbital section of the optic nerve extends from the globe‚ where it inserts medially‚ to the optic canal located in the lesser wing of the sphenoid bone. It is encased by a meningeal sheath consisting of dura mater‚ arachnoid mater and pia mater. Cerebrospinal fluid is contained in the trabeculated subarachnoid space and is continuously and slowly filtered. As a result the optic nerve sheath is in direct

is which type of temperature change will result from heating ice to liquid‚ then boil (steam)? What will happen to the water after the boil? I hypothesise the water heats ice to liquid and then goes to simmer and boil. The independent variable is the hot plate changed to a burner itself. The dependent variable is what we are measuring is the time. The steps in the lab were to first start off with a burner‚ ice and water in a beaker‚ then record time and water temperature. Also‚ some phase

Negative Temperature Coefficient (NTC) thermistors exhibit a decrease in electrical resistance when subjected to an increase in body temperature and Positive Temperature Coefficient (PTC) thermistors exhibit an increase in electrical resistance when subjected to an increase in body temperature. U.S. Sensor produces thermistors capable of operating over the temperature range of -100 ° to over +600 ° Fahrenheit. Because of their

To begin the analysis‚ the properties of the air at the base of the tower were examined. The wet and dry bulb temperatures of the air at the inlet were used to find the humidity‚ humid volume‚ and enthalpy of dry air. For example‚ in the first trial the dry bulb temperature was 22.5⁰C and the wet bulb was 16.5⁰C‚ and the properties found from the psychrometric chart are listed below. H_bottom=0.0095 kg/(kg dry air) V_bottom=0.85 m^3/(kg dry air) h_bottom=47 kg/(kg dry air) Then‚ the cross-sectional

Chapter 6 Measuring Vital Signs Unit 1: Temperature‚ Pulse‚ and Respiration UNIT RATIONALE Important indicators of your patient’s/client’s health status are known as vital signs. Vital signs give you information about breathing‚ body temperature‚ and the heart. They are a good indication of how well the body systems are functioning. As a health care worker‚ you need to observe patients whenever you are near them. Your knowledge of vital signs and how to measure them helps you know when to report

Lab Report: How Temperature affects Reaction Rate Aim: The Aim is to investigate how temperature can affect Reaction Rate. The experiment will be performed by heating equally sized and weighted lime stones with equal amounts and concentration of Hydrochloric acid at different temperatures. The temperatures will be 35˚C and 40˚C. We will measure the reaction rates by observing gas release of the reaction between lime stones and Hydrochloric acid. The amount of gas release at different
