Biology Unit 2 Module 2 1.1: Explain the uptake of ions by active transport in roots; * Emphasize the role of the endodermis. Most plants secure the water and minerals they need from their roots. The path taken is: soil -> roots -> stems -> leaves The minerals (e.g.‚ K+‚ Ca2+) travel dissolved in the water (often accompanied by various organic molecules supplied by root cells).Less than 1% of the water reaching the leaves is used in photosynthesis and plant growth. Most of it is

Deep ecology is a way of life. A way of life that is shifting the way we view ourselves as humans. Deep ecology is the means of shifting the value of humans to non-human nature. Humans can no longer look at themselves as the sole entity of the ecosystem‚ but part of a whole that needs each part to successfully work. Fritjof Capra believes that shifting our views from the old world anthropocentric to new world non-anthropocentric is the key to the survival of the human race. Having anthropocentric

Biology is a natural science concerned with the study of life and living organisms‚ including their structure‚ function‚ growth‚ evolution‚ distribution‚ and taxonomy.[1] Modern biology is a vast and eclectic field‚ composed of many branches and subdisciplines. However‚ despite the broad scope of biology‚ there are certain general and unifying concepts within it which govern all study and research‚ consolidating it into single‚ coherent field. Biology generally recognizes the cell as the basic unit

Some of the issues in that time were slavery and the judgment of your race or skin color. Mark Twain shows these issues though the eyes of Huck Finn sometime children may have better heart then the elders

Lab: Inhibiting the Action of Catechol Oxidase By: Kimberly G. Introduction: In this lab‚ Mr. Greene ’s sixth period AP Biology class split into groups "to investigate inhibition of enzyme activity by specific chemicals called inhibitors" (1). Group three pondered this lab ’s inhibitor‚ phenylthiourea (PTU). Is it a competitive inhibitor? That is an inhibitor that literally "competes" with the substrate by mimicking it‚ and thus "wins" the position at the active site of the enzyme. The blocked

AP PSYCH REVIEW ESSAY 7 A. A cognitive map is a mental representation of the layout of one’s environment. This is very helpful when driving because it enables the driver to easily get around as well as get to specific destinations easily. The cerebellum is a structure often referred to as the "little brain" that is located in the rear of the brainstem that plays a significant role in a person’s balance & coordination. Having good coordination is extremely important when driving because many
