Purpose and Hypothesis: Purpose To determine if light intensity affects the rate of growth in Brassica rapa. Hypothesis If the plant that is exposed to high intensity light grows more‚ then plants can adapt to absorb more photons for photosynthesis. Eventually‚ the rate of photosynthesis will top out‚ and stop increasing‚ due to the lack of one of the components necessary for photosynthesis. Background: Photosynthesis is a process used primarily by plants but sometimes by other organisms to

IS LANGUAGE UNIQUE TO THE HUMAN SPECIES? by Ulla Hedeager INTRODUCTION The assertion that humans differ from animals in their use of language has been the subject of much discussion as scientists have investigated language use by non-human species. Researchers have taught apes‚ dolphins‚ and parrots various systems of human-like communication‚ and recently‚ the study of animal language and behaviour in its natural environment rather than in the laboratory has increased. It is my aim to discuss human

This paper describes the origins of biomolecules hypothesis. Each different hypothesis is derived from a different scientist. It explains their claim and answers the question if the origin of biomolecules using their hypothesis. All the scientists provided evidence to help support their hypothesis. Some of the scientists had experiments to test their hypothesis. They also gave reasoning for supporting their theory. The Primordial Soup Hypothesis was introduced by the Soviet biologist Alexander

invasive species can be any kind of living organism an amphibian‚ plant‚ insect‚ fish‚ fungus‚ bacteria‚ or even an organism’s seeds or eggs that is not native to an ecosystem and which causes harm. Species that grow and reproduce quickly‚ and spread aggressively‚ with potential to cause harm‚ are invasive species. Invasive species are primarily spread by human activities‚ often unintentionally. People‚ and the goods we use‚ travel around the world‚ and they often carry uninvited species with them

The cardiovascular system is made up of the heart and blood vessels‚ which are divided into arteries‚ veins and capillaries. The blood delivers nutrients and oxygen to the cells in the body. The arteries carry blood away from the heart and the veins carry it back to the heart. Capillaries are found in the muscles and the lungs‚ they have valves to stop the blood flowing backwards and this is also where gaseous exchange takes place. The heart works as a pump that pushes blood to the organs‚ tissues

LOSES OF BIODIVERSITY Some species that are more vulnerable to extinction than others include species at the top of food chains‚ such as large carnivores. Endemic local species which is a species found in only one geographical area with a very limited distribution‚ species with chronically small populations‚ migratory species‚ species with exceptionally complex life cycles and specialist species with very narrow requirements are also the examples species that are more vulnerable to extinction

Aquatic Invasive Species Two thirds of the forty freshwater fish extinctions are known to have been caused by invasive species. The extinctions could have been caused by any one of the four thousand three hundred known invasive species in the United States. In Minnesota‚ the land of ten thousand lakes‚ thirty-five percent of all recreational waters are known to hold at least one invasive species (Invasive species of aquatic plants and wild animals in Minnesota: Annual report).

Love Alone is Believable: Hans Urs von Balthasar’s Apologetics | Monsignor John R. Cihak | Ignatius Insight The greatest challenge I find in bringing someone to Christ and his Church is finding ways to engage him in meaningful conversation. Talk of truth is often met with a yawn‚ and an assertion about what is good is met with a stare of incomprehension. In the malaise of contemporary American life‚ people do not seem to be moved much by claims of truth or goodness. Relativism has made truth
