Stomata are tiny pores found on the epidermis of the leaf‚ surrounded by guard cells. [1] Their main function is gas exchange [1] for photosynthesis and respiration. The development of stomata on the leaves of a plant is determined by interaction between different genes and environmental factors. A few studies have been conducted in order to establish a relationship between stomatal densities and given environmental factors. Research has shown that stomatal densities are controlled by environmental

will be found. It will not be long. You might want to do one treatment to maintain your state of health‚ which is dialysis. Just I want to explain to you one thing about the necessity of dialysis. Look‚ you cannot produce urine and all waste from your body is accumulated into your blood. This waste is toxic or if it is not removed‚ you might have a range of symptoms. I know that dialysis is quite unconfutable treatment‚ but

Analysis During the experiment‚ a dialysis bag was used to mimic a cell membrane. Two ways why this model realistically represents a cell is because the dialysis bag is semi-permeable‚ like a cell. The bag was able to allow water in‚ as the size of the water molecule was small enough to be able to fit through the pores of the bag. Sucrose was not able to pass through as the molecules were too big to enter. This is similar to a cell because the size of a molecule can determine whether or not the

Cinthya Perez Per.3 AP Biology 11/20/12 1.) In the structure of a eukaryotic plant cell consist of a membrane-closed nuclei and organelles‚ since they developed a process in which they manufacture their own food. The Chlorophyll‚ which gives the plant the green color captures sunlight to convert water and carbon dioxide into glucose and carbs‚ in which are used for the repetition of the cycle. Not only does the plant cell consist of a membrane‚ unlike other eukaryotic cells it additionally

The Effects of Environmental Stimuli on Animal Behavior AP Biology Emily Olsen April 26‚ 2012 I. Introduction: The purpose of this lab is to test the effect certain stimuli has on the behavior of a terrestrial isopod. These bugs are more commonly known as pill bugs and potato bugs. The objective of this experiment is to determine which kinds of habitats potato bugs favor. Potato bugs have an innate behavior called taxis which will cause the animal to move away from a stimulus that is unwanted

Living On Dialysis By Ruth Bautista Change is unsettling to most people. And one of the most unsettling change we experience is life is having an illness. Illness brings unwanted change and it also brings unwanted emotions. More often than not those emotions do not feel safe. These cause us to feel out of control and without foundational security. It causes us to lose our moorings and set us adrift on a frightening sea of unfamiliarity. Take patients with kidney failure for example. Most of

DNA QUESTION 1995: L. PETERSON/AP BIOLOGY The diagram below shows a segment of DNA with a total length of 4‚900 base pairs. The arrows indicate reaction sites for two restriction enzymes (enzyme X and enzyme Y). (A) Explain how the principles of gel electrophoresis allow for the separation of DNA fragments. (B) Describe the results you would expect from electrophoretic separation of fragments from the following treatments of the DNA segment above. Assume that the digestion

Their scientific name is Drosophila melanogaster‚ and to scientists‚ they have been a key to understand many principles of heredity including sex linked inheritance‚ epistasis‚ multiple alleles‚ and gene mapping.

1. The hypothesis if water is added to the cup then the mass and volume will decrease because water will go into the tubing to decrease solute concentration was supported by the data found in Table 1 and 2 because the cup holding the dialysis tubing with the protein solution’s mass decreased by 7.61 grams and the volume decreased by 17.3 milliliters while the mass of the cup with the tubing holding glucose solution also decreased by 1.19 grams and the volume decreased by 2.2 milliliters (Emma Ricks
