Unit 3 Lecture Study Guide 1. List the 4 primary tissue types and give the general characteristics and functions of each one. Epithelium- The epithelium protects us from the outside world. Skin‚ absorbs. Stomach and intestinal lining‚ filters. The kidney‚ secretes. Forming of glands‚ closely attached to each other forming a protective barrier‚ always has one free surface open to outside the body or inside an internal organ‚ has no blood vessels but can soak up nutrients from blood vessels in connective

Susan Griffin compares and contrasts cellular life and weaponry as she writes her essay‚ Our Secret. She uses these ideas together with characters and events‚ to help explain causes and effects in the essay. She alternates from the cell’s function to the history of weaponry throughout the essay. With both these ideas‚ she starts at the elementary level‚ with a cell’s life and with the Vergeltungswaffe missile‚ and tells how they progress. In this essay‚ I will describe how Griffin uses cellular life

Biology‚ 7e (Campbell) Chapter 17: From Gene to Protein Chapter Questions 1) Garrod hypothesized that "inborn errors of metabolism" such as alkaptonuria occur because A) genes dictate the production of specific enzymes‚ and affected individuals have genetic defects that cause them to lack certain enzymes. B) enzymes are made of DNA‚ and affected individuals lack DNA polymerase. C) many metabolic enzymes use DNA as a cofactor‚ and affected individuals have mutations that prevent their enzymes

Indicate whether each of the following statements about triglycerides is true or false. Indicate whether each of the following statements about triglycerides is true or false. 1. A triacylglycerol is composed of 3 glycerol molecules joined to a fatty acid. 2. The hydrocarbon chains of fatty acids vary in length as well as in the number and location of double bonds between the carbon atoms. 3. Fatty acids with one double bond in their hydrocarbon chain are called monounsaturated‚ while those with

antigen-binding bacteriophage can then be used to create antibody libraries‚ for further studies on the antibody and its possible uses in drug discovery. Figure 1. Overview of the steps involved in the generation of human antibody Fab libraries. Messenger RNA is isolated from peripheral blood of donors and copied into cDNA. This material is then used as template for PCR amplification of immunoglobulin gene fragments‚ which in turn are cloned and expressed as functional Fab molecules in fusion with

separates the contents of the nucleus from the cytoplasm‚ all in all keeping the DNA safe and intact. The nuclear envelope regulates the flow of substances into and out of the nucleus. The NUCLEOLUS is an important structure found within the nucleus. The RNA‚ which will be made into ribosomes is synthesised in the nucleolus. The ribosomes move out of the nucleus to help with protein synthesis. The ROUGH EDOPLASMIC RETICULUM looks rather “pebbeled” through a microscope because of the ribosome’s that are

substrate (Kim‚ 2005). A codon is a group of three bases of DNA which code for a specific amino acid. The amino acids make up a polypeptide chain‚ forming the protein. The section of DNA that is needed is unwound and read by RNA polymerase‚ which makes messenger RNA (Kim‚ 2005). 20 types of amino acids join and make several kinds of protein. However‚ one ’s body cannot make some amino acids and are known as the essential amino acids. With diets‚ protein sources are often labeled by how many essential

A ’tropism’ is a growth in response to a stimulus. Plants grow towards sources of water and light‚ which they need to survive and grow. Auxin is a plant hormone produced in the stem tips and roots‚ which controls the direction of growth. Plant hormones are used in weedkillers‚ rooting powder and to control fruit ripening. Tropisms The direction of plant growth Plants need light and water for photosynthesis. They have developed responses called tropisms to help make sure they grow towards sources

Endocrine System Chapter 13 Study Guide Name ( ) Revision 2 OVERVIEW The endocrine system‚ like the nervous system‚ controls body activities to maintain a relatively constant internal environment. The methods used by these two systems are different. This chapter describes the difference between endocrine and exocrine glands‚ the location of the endocrine glands‚ and the hormones they secrete (objectives 1 and 6). It explains the nature of hormones‚ the substances that function as hormones
