because blue light has a higher absorbance by plant photosynthetic pigments and has a higher energy wavelength than red light‚ we predicted that juniper needles placed in blue light would photosynthesize faster than juniper needles placed in red light. We measured the rate of change in CO2 concentration due to juniper needles. For each sample‚ we placed the needles into a chamber connected to the CO2 monitor and measured the rate of change of CO2 concentration for 10 minutes under red light and then

disadvantages of a light microscope and electron microscope? Some of the disadvantages of the light microscope include‚ that since it send light‚ the light waves are diffracted as they pass through the matter. Because of this‚ light microscopes can only produce clear images of objects to a magnification of about 1000 times. Another problem is that since most living cells are nearly transparent‚ you can’t see them. So you have to use dyes to stain them. The advantage of using a light microscope however

The poem The Halo That Would Not Light sent me on a religious journey with the title itself. According to Merriam Webster‚ a halo is a circle of light that is shown in a religious painting‚ drawing‚ etc.‚ around the head of a holy figure (such as an angel‚ saint‚ or god). Which leads me to believe that there is a religious figure that this person is looking forward to coming but their halo will not light which means they never came. In the first couple of lines‚ “When‚ after many years‚ the raptor

In Joseph Conrad’s Heart of Darkness‚ the juxtaposition of light and dark -- in addition to an abundance of imagery-- serves as a vehicle to understanding Conrad’s tainted view of humanity as deeply flawed. There are reoccurring light and dark images which symbolize the good and evil in mankind. Light represents both goodness and civilized Europe. Ironically‚ the light Europe is the place where the worst people are. Europeans are civilized‚ but inhumane. In contrast the references to darkness symbolize

fluorescent light and why ultraviolet light is required to visualise it. (5 marks) When GFP is hit with UV light‚ the chromophore is hit by a photon. This changes the chromophore from ground state (A) to A*‚ which is a highly excitable state. Due to such a highly excitable state not being able to remain so for very long‚ the A* state chromophore emits a proton‚ lowering its state to I*‚ the energetic I. This I* state chromophore lowers its energy by emitting a photon of green light‚ lowering its

was a never-ending one. Throughout the novel‚ Hawthorne uses the symbols of light and dark to depict this battle among the characters Hester Prynne‚ Pearl‚ and Roger Chillingworth. <br> <br>After Hester commits her sin‚ her beauty almost immediately vanishes into darkness. Her hair no longer hangs freely about her face‚ instead she ties it up in a bonnet. Hester is not perceived as an evil person‚ but her sin makes her "light" hide away. The sun is used as a descriptor of the goodness or pure nature

How light intensity effects the Rate of photo synthesis. Aim The aim of my experiment is to find out how light intensity affects the rate of photosynthesis. Prediction I predict that as the light intensity increases that the rate of photosynthesis will increase in proportion‚ so for example if you increase the light intensity from 10cm away to 20 cm away form a stationary plant. There for the rate of photosynthesis will decrease proportionally with the distance of the light from the plant (in

This motif of “the play of light and shadow” Chiaroscuro referenced was seemingly extended by program Seven of the Here/Now Festival throughout the evening. Two works representative of “shadow”‚ Funérailles and Oltremare‚ were interspersed between the three—Ash‚ Common Ground‚ and Rodeo: Four Dance Episodes—in which “light” predominated. While Ash is not a particularly distinctive ballet‚ it was delightful to watch Ashly Isaacs here. In this piece‚ each one of various members of the corps is notably

There are two contrasting views that light either consists of particles or waves. Light is a perplexing phenomenon puzzled by Ancient Greeks and scientists for years. Even Issac Newton developed incorrect theories on light‚ when he was the inventor and genius behind physics. It has been proved that light can be both a particle and a wave. Human eyes collect light that is reflected from a source. For example‚ the light from a pencil comes from the source of light in the sun and travels to the pencil
