Complete the Scientific Method activity on the student website. Write a 350 word paper on the scientific method. Include the following: Describe how you applied the steps of the scientific method in the activity. Describe a real-life problem where you have or could have used the scientific method. Include the steps involved in solving the problem. I completed both the tomato growing and the car starting exercises. I first identified the problem. The tomato plants were not producing

Characteristics of Living Organisms In order to identify living organisms‚ scientists listed 7 characteristics which all living organisms have: 1. Nutrition: Taking in nutrients which are organic substances and mineral ions‚ containing raw materials and energy for growth and tissue repair‚ absorbing and assimilating them. 2. Excretion: Removal from organisms of toxic materials‚ the waste products of metabolism and substances in excess. 3. Respiration: Chemical reactions that break

In completing the Tomato Plant experiment I had to apply the scientific method. I observed that my tomato plants were producing less fruit each year. I then questioned some of the elements that may have affected the tomato plants and caused them to bear fewer tomatoes being a deficiency in warmth‚ water‚ or nutrients. I then selected my hypotheses that the plants were in need of more nutrients. Following my hypothesis I developed my prediction which was that my plants would bear more tomatoes if

Observing the Characteristics of Life In this activity‚ you’ll identify some observable characteristics (some not) of life in videos of various organisms and describe those characteristics. Review Remember that ALL living organisms are made up of CELLS! What are seven characteristics of living things? 1. Movement 2. Reproduction 3. Sensitivity 4. Growth 5. Respiration 6. Nutrients 7. Excretion If your teacher is displaying the

The importance of carbohydrates in living organisms Carbohydrates contain carbon‚ hydrogen and oxygen in the ratio of 1.2.1.. There are many different types of carbohydrate‚ all of which are useful to living organisms. The most important carbohydrate is probable glucose. Glucose is a monosaccharide and is the monomer unit which makes up more complex polysaccharides. Two glucose molecules can be joined in a condensation reaction‚ whereby water is removed‚ for example to produce maltose‚ a disaccharide

of living organisms‚ the solvent (water) would have net movement across a selective permeable membrane. Osmosis only occurs when a membrane such as that of a cell is permeable to water molecules but not to specific solutes (Tortora & Derrickson 2014). Certain simple molecules such as oxygen‚ water and carbon dioxide can travel across the cell membrane by osmosis‚ a passive process similar to other forms of diffusion (Hill 2007). Not merely is it vital to several processes in living organisms‚ it

Amongst many problems that living organisms face‚ one of the biggest is the change in the temperature of the environment. Why is this a major problem for living organisms? A change in the temperature of the environment disrupts many of the body’s enzymes and regulatory proteins‚ changing their shape and perturbing their function. However‚ organisms have taken two different approaches to tackling this problem we call this organisms endotherms and ectotherms but in this essay‚ we will talk about an

ionic‚ polar or covalent will dissolve in it‚ therefore more reactions take place while in solution with water. Often in organisms substances must be in solution and water is the solvent. Plants can only obtain mineral salts in solution and human digestion will only dissolve soluble foods‚ meaning large starch molecules must be broken down into soluble sugars. Also many organisms living in water spend most of their time underwater‚ yet they require oxygen to respire‚ and as water is such a good solvent

2.1 Identify the differences between bacteria‚ viruses‚ fungi and parasites. Bacteria – bacteria are extremely small singular organisms which are found almost everywhere. Viruses – it is a coated genetic material that invades cells and use’s the cells apparatus for reproduction. Fungi – it is a multi-celled living organism Parasites – they are types of living plants and animals that derive benefit from the metabolism of other animals and plants. 2.2 Identify common illnesses and

The effect of mutations on living organisms Mutations occur when there is a change in the base sequence on the DNA strand. Most mutations have absolutely no effect due to them occurring in the introns‚ or the “junk DNA”. However some mutations occur on the exons‚ and these are the ones that can be potentially harmful to the organism‚ although in some exceptional cases random mutations can be beneficial‚ and pressured mutations are almost always beneficial to the survival of a species. Harmful
