The reason why humans first look for water when they travel to other new planets due to the fact that in order for living organisms to survive in those planets, there needs to be sources of water to sustain life on those planets. If humans can find water on a different planet, then they could make the claim that life could already be on these planets, or that life can be sustained on these planets. My evidence is that in order for life to be sustained on a planet, this planet must contain the six

The isolation and purification of genomic DNA requires three main processes which include, lysing of cells to release the DNA, purifying the solution by removing unwanted macromolecules, and precipitating the DNA from the solution. The process of isolation and purification requires several reagents. The Nuclei Lysis Solution contains lysozyme and EDTA. The lysozyme is an enzyme that degrades peptidoglycan, which is a rigid exoskeleton cell wall that protect the bacteria (3). Disrupting the peptidoglycan

right amount of food and drink to achieve and maintain a healthy body weight. A balanced diet consists of vitamins, carbohydrates, minerals, vitamins, fats (lipids) and fibre which is also known as roughage. CARBOHYDRATES Carbohydrates are macromolecules which and contains carbon, hydrogen and oxygen (C,H,O). There are also two types of sugars, sweet soluble and starches which are non-soluble. Sugars can also be single or simple sugars.Carbohydrates can be found in a wide variety of foods such

detection of starch presence, Benedict’s test for determination of reducing sugars presence, Biuret test for the detection of protein present, and emulsion test for lipid detection. The two food samples were tested simultaneously for the presence of macromolecules and the tests carried out gave negative results except for Benedict’s test. Under Benedict’s test, the

Nucleus The nucleus is the largest of the organelles and is enclosed by a nuclear envelope. Aspinall/Cappello (2015) describe the nucleus as ‘the information centre of the cell’. The nuclear envelope has two membranes which has nuclear pores – the pores are in charge of exchanging materials between the cytoplasm and the nucleus. The envelope contains phospholipids, this forms a lipid bilayer which helps to maintain the nucleus’s shape. This also helps with the movement of molecules in and out of

receive when they enter the body after being occupied from the outside sources in the form of different nutrients. The purpose of this lab is to test the process of hydrolysis occurring in different macromolecules by using the biochemical tests. This lab also indicates the hydrolysis of macromolecules when heat or acidity is applied to the molecules or compounds. The molecules that are being observed in the experiment are the polysaccharides and proteins, two main components that play an important

__________. 9. The name of a chemical reaction to break molecules by inserting a water molecule is called __________. 10. What are the 4 main elements of the body? 11. What are the 4 macromolecules called? What are their “building blocks”/subunits (monomers) called? Give functions of each macromolecule and examples. 12. What is the main energy currency of the body? 13. What is the smallest unit of life with living properties? 14. What is a cell called if it doesn’t have a nucleus

gas). This occurs because the molecules with the greatest energy (the “hottest” ones) tend to vaporize first. 2. List the four major classes or groups of biologically important macromolecules and explain one reason for the importance of each. The four major classes or groups of biologically important macromolecules are Carbohydrate, Lipids, Nucleic, and Protein. Carbohydrate are any of a group of organic compounds that includes sugars, starches, celluloses, and gums and serves as a major energy

tested positive for lipids. The first group of foods that were tested was the fruits and they consisted of apples, bananas, plantains, and avocados. The apple, banana, and plantain contained starch and sugar and this is correct because these two macromolecules are present in plants. The only exception to this group is the avocado. It contains a small amount of starch (since it is still a plant), but it also contains proteins and lipids because of its single large pit (seed) whereas the other fruits
