the slope of the line increases and shows a slight curve. The rate of evaporation increases with temperature since transpiration is a cooling mechanism to release heat. More stomata open as temperature increases as this allows a faster transpiration rate. Although‚ at much higher temperatures‚ plants close stomata to prevent excess water loss. b. The increasing humidity causes reduced transpiration rates. This is because atmosphere is saturated with water vapor and so not much can be absorbed

Variable was the heat lamp‚ and the dependent variable was the temperature of the soil‚ because the temperature varied based on whether the heat lamp was turned off or on‚ and whether there was extra water added or not. Our hypothesis was proven correct‚ because the dry soil’s temperature was hotter than the damp soil’s temperature when the heat lamp was on‚ but then it decreased when it turned off‚ while the damp soil’s temperature remained the same. This is because dry soil contains little moisture

environment that is rainy and humid. The rain forest only has one season because it’s weather and temperature never change. The temperature never changes because of the high humidity rate and waters thermal resistance. The rain forest has direct sunlight that provides light and heat but indirect only provides light. Rain forests have an average temperature of 80 degrees fahrenheit. The temperature may feel hotter due to the high humidity rate. Rain forests can receive 100 to 300 inches of rain

An experiment proving transpiration in leaves Aim To see how different environmental conditions affect transpiration of a leaf and which side of the leaf transpires the most. Background Information Plants put down roots into the soil to draw water and nutrients up into the stems and leaves. Some of this water is returned to the air by transpiration (when combined with evaporation‚ the total process is known as evapotranspiration). Transpiration rates vary widely depending on weather conditions

What affect does exercise have on these parts of your body? Heart‚ Lungs‚ Muscles‚ Joints and Body Temperature? After exercise‚ you’ll find your body experiences immediate and more gradual effects. The minute you start training‚ you’ll notice more frequent muscle contraction‚ raised body temperature and pulse‚ and deeper breathing known as tidal volume. Longer-term effects occur as the body adapts to regular exercise‚ including your heart getting larger‚ bones becoming denser and the vital capacity

Biology Assignment Transpiration rates between Exotic vs. Native plants In this investigation we will be looking at transpiration. The topic we will be focusing on is transpiration rates between native plants as well as exotic plants. We will be experimenting with 2 native plants as well as 2 exotic plants. The reason we are experimenting on this topic is because of Australia’s dry weather‚ we are wanting to find out which plants will be able to hold more water during Australia’s peaking tempretures

Caffeine stimulates receptors located in cells within your heart to increase your heart rate. Effects of this stimulation speed up your blood flow because of an increase in heart rate‚ as well as an increase in blood sugar‚ urine production and body temperature. Function Physiologically‚ caffeine stimulates the receptors within your heart to beat faster by blocking the enzyme phosphodiesterace. Phosphodiesterace works together with another enzyme‚ cyclic AMP‚ to keep your heart rate at its normal range

How Does Karma Affect You? Final Revision Jamie Hansen English 090 / Winter 2013 Professor Laura Weber March 13th‚ 2013 What side of karma are you on? For those who believe‚ there are two sides to karma: good and bad. I believe karma will work with you or against you‚ it just depends on if you choose to be a good or bad person. When I see someone who is being mean‚ rude or disrespectful as well as when I see someone being kind‚ helpful or respectful‚ I can’t help but wonder how and when

How exercise affects certain aspects of the body During exercise our body needs more oxygen and blood to keep the muscles activated. To grant this the heart pumps higher frequency of blood increasing the heart rate. Heart pumps blood through arteries faster resulting in a high blood pressure. Exercise increases the stroke volume (the amount of blood pumped in one beat)‚ so an increase in stroke volume means that the heart can pump enough blood to the body with fewer beats per minute. Even after the
