Biomes Comparison Essay Ecologists group earth’s diverse environments into biomes. A biome is a complex of terrestrial communities that develops a large area and is characterized by certain soil climate conditions and particular assemblages of plants and animals. Not all species live in every biome they vary in their adaptations to different conditions. An adaptation is an inherited characteristic that increases an organism’s ability to survive and reproduce. These sorts of variations in plants

A2 Biology Coursework A1- Develop a hypothesis Outline your biological knowledge or research related to the problem under investigation Yeast are eukaryotic species and make up approximately one percent of species in the kingdom Fungi. One of the most well studied yeast species‚ Saccharomyces cerevisiae‚ commonly known as bakers yeast‚ and also used in the fermentation of alcohols‚ is a model species for the study of eukaryotic cells. They are known to reproduce either sexually‚ by mitosis‚

1.There are three basic types of amino acids: 1) those with electrically charged side chains; 2) those with polar side chains; and 3) those with nonpolar side chains. A) True B) False2.All amino acids share a common “backbone”. Which chemical component (or components) is part of the backbone of an amino acid? A) An amino group (NH2) B) A carboxyl group (COOH) C) A hydrogen atom D) A central carbon atom that is commonly called an α-carbon atom E) All of the above3.Suppose that we link 100

Planning Introduction Stomata are pores on the bottom of leaves of vascular plants. The function of stomata is to allow gaseous exchange (transpiration) between the plant and the external environment (see diagrams below). This process is carried out by the plant‚ which controls the opening and closing of stomata via the guard cells. The more stomata a leaf contains the greater the rate of gas exchange and the less water it will be able to accumulate. Stomatal pores are formed between

Male System The structure and function of the human male reproductive system‚ is very similar to that of many other mammals. The male system is designed to make sperm or male gametes and is adapted to provide for the delivery of these gametes to the female to allow for fertilization. Male Reproductive System Male Reproductive System Structures 1. testes -- produces sperm and the hormone testosterone 2. scrotum -- pouch enclosing the testes keeping the sperm at an optimum temperature

32.2.2 Segmentation allowed for redundant systems and improved locomotion Hox genes cause segmentation development 2 advantage of Hox genes Highly segmented animals‚ usually have nearly complete set of organs in theirs each segment of body. This result to less damage in their body‚ since other segment duplicate the damage segment functions Locomotion is more efficient‚ since partitions isolate the segment can contract and expand autonomously. 32.3. The Classification of Animals Animals divided

regulate gene expression has been a quandary. Biology is a highly fragmented science with delicate details at all levels where macromolecules perform a wide array of functions necessary for the survival and growth of living organisms and hence important cellular components.

Biology- Maintaining a Balance Summary 1. Most organisms are active in a limited temperature range 1. identify the role of enzymes in metabolism‚ describe their chemical composition and use a simple model to describe their specificity on substrates Enzymes are proteins which act as catalysts in living things (they lower the amount of energy needed for a reaction‚ therefore increasing rate of reaction). Enzymes speed up reactions but are not used up by them. Enzymes catalyze only one

The effect of time on enzyme reaction. Abstract: In this lab investigation we will observe how the amount of hydrogen peroxide is affected by catalase over time. The enzyme was added to 10 mL’s of hydrogen peroxide and observed over time to determine the relation between time and enzyme activity. The hypothesis stated that as time increased substrate would decrease. Therefore I predicted that at 60 seconds‚ there would be the least amount of H2O2. The enzyme activity mirrored my predictions

Title: Catalase enzyme detection Objective: To understand the function of catalase in cells that produce the enzyme‚ interpret the results of a catalase test and know their value in differentiating bacteria. Materials: 1 clean microscopic slide‚ 3% H2O2 solution‚ swabs. Micrococcus luteus‚ Enterococcus faecalis‚ patient G Procedure: 1) Scrape some cells off from each bateria to the slant and place them on glass slide. 2) Place one or two drops of H2O2. Watch for bubbling as an indication of
