the DNA form in a nucleus when a cell isn’t undergoing mitosis (ie when a cell is in interphase)? The term for the DNA form in a nucleus when a cell isn’t undergoing mitosis is known as chromatin. 4. Why is mitosis important for multicellular organisms? Mitosis is important for multicellular organisms for many reasons. For an example‚ one reason is that wounds and cuts can be healed and repaired by adding new cells in the cell division

Diffusion and Osmosis Through Dialysis tubing We did this experiment to test the diffusion of different substances through dialysis tubing. We used what we knew about diffusion to make predictions on what we thought the mass of the dialysis tubing to be after submerging them for 30 mins and we knew that diffuse occurs from highest concentration to lowest concentration. Since the dialysis tubings are filled with different substances than what they are being put into then they should all gain

Biology Unit 4 Chapter 1: “Terrible Lizards” Paleontologist: someone who studies “ancient organisms” Paleobiology – the study of ancient life Paleontology is particularly important with regard to scientific theory‚ since for many children dinosaurs are the first exposure to scientific concepts Early Dino Stuff In 1676- large meat- eating femur (Megalosaurus) was discovered and people thought it was a giant human’s scrotum – “Scrotum humanum” First scientific name given to dinosaur Prior to 1800s

showing that certain colors are more advantageous than others. 3. What is pollination? Pollination is the transfer of pollen from the male reproductive organ (stamen) to the female reproductive organ (pistil) of the same or of another flower. 4. Which of the flowers you observed today will have the highest chance of being pollinated? Explain your choice. Of the observed flowers today‚ the one with the highest chance of being pollinated would be the sunflower. The sunflower had the brightest

AP Biology Lab 1 Ross Lordo Introduction Questions 1. The solute potential would be -2.48. If the concentration inside the cell is .15 M‚ then would diffusion out of the cell and into the solution of .1 M. This is due to water potential and the tendency for water to move from areas of high water potential to low water potential. 2. The turgor pressure must be equal to the water potential if there is no net diffusion. The cell and environment have reached equilibrium and the movement of water

Adriana Gutierrez AP Biology Lab 9 Analysis 1. For this experiment‚ what were the independent variable and the dependent variable? What were the constants? The independent variable of this experiment are the environmental factors that you are testing on the rate of transpiration‚ so our independent variables would be bright light‚ fan‚ dark‚ and misted. The dependent variable is the rate of transportation because this depends on whatever environmental factor the plant is placed. The constants

NEOCLASSICISM IN FRANCE As in Britain‚ the reaction against the Rococo in France first appeared in architecture. This sublime phase of Neoclassicism had a profound impact on painting. Architecture: Rational Classicism The first phase of French Neoclassical architecture was a reaction to the excesses of the Rococo‚ which had been about asymmetry‚ graceful movement‚ decorative flourishes‚ and curvilinear elegance. The new architecture was about rational design‚ and hence is often called Rational

Enzyme kinetics (catalase/kmno4) Enzyme catalysis Farah Mohamed galal 22-3014 t09 Introduction: E + S → ES → E + P Enzymes are proteins which act as a catalyst in biochemical reactions(affect the rate of achemical reaction). The substrate binds to the active site of the enzyme. Any deformation of the active site will affect the activity of the enzyme‚ these are some ways that enzyme action may be affected because of them: 1- Salt concentration: If it is close to zero or very high

Terra shiles English 232 Mullinax September 18‚ 2013 The Book vs. The Movie The Legend of Sleepy Hollow written by Ivring was a very interesting story that is well known around the world today. The movie was far more entertaining than reading the book If I must say so myself. Tim Burton gave a new spin to The Legend of Sleepy Hollow. I myself have always enjoyed anything written or directed by Tim Burton because of his sense of horror and his creative abilities. The characters are redefined
