How a culture views the human figure varies greatly. Two cultures can infer and believe whatever they choose because there is no right way. Two cultures that perceive the human figure differently are The Greeks and The Olmecs. The Greeks love analyzing the human figure and are very passionate about human perfection. The Olmecs on the other hand had a very different perception on human perfection and the human figure. Two pieces of artwork that represent the Greek culture well are the Doryphoros Spear Bearer statue, a marble copy of a bronze original created by the Polykleitos during the Greek culture, and the Kritios Boy sculpture which is also a marble sculpture created around 480 BCE.

Ian Konrad 4-23-14 LEH Mrs. Guido Flower Anatomy Activity 1a. Record the number of sepals observed in your flower specimen and give 1 function. There were 12 sepals on my flower. One function of the sepals is to protect the flower while it is forming a bud. 2a. Record the number of petals - what advantage do colorful petals provide for the flower? There were 6 petals on my flower. Colorful petals attract pollinators such as bees to come and pollinate the flower. 2b. Why are sepals considered accessory parts of the plant? Sepals are considered accessory parts of the plant because they are not directly involved in pollination. 3a. Record the number of stamens and give 1 function.

Introduction to Psychology (Section 2B) Individual Report Topic: Reducing Academic Procrastination Introduction Procrastination is a well-known problem among students in secondary schools and universities. According to Laura J. Solomon & Esther D. Rothblum(1984), procrastination is experiencing subject discomfort from the act of needlessly delaying tasks. What are the reasons causing students to procrastinate? How can we reduce procrastination? These are the questions we always want to ask since procrastination is regarded as a disturbing phenomenon that we want to get rid of it. (Steel, P., 2007). In this research, we hope to have an in-depth understanding of academic procrastination and seek practical solutions for it. Project Summary Research Aim:
