Answer:
1. antibodies
2. hormones
3. kidney stones
4. transport proteins
5. protein-energy malnutrition
6. coenzymes
7. buffer
8. kwashiorkor
Explanation:
1. ANTIBODIES are proteins that aid the immune system in its fight against bacteria, viruses, and other foreign substance by binding to them and helping to inactivate or destroy them.
2. HORMONES are substances made of protein or lipid released into the bloodstream in order to direct physiological activity in the body.
3. A high-protein diet can increase the risk of KIDNEY STONES because the body will have an increased acid level.
4. TRANSPORT PROTEINS carry many substances through the blood or allow movement of substances in and out of cells.
5. PROTEIN-ENERGY MALNUTRITION is the phenomenon used to describe an inadequate intake of proteins and/or calorie content.
6. COENZYMES are molecules that play vital roles in the function of an enzyme. Coenzyme in form of vitamins are utilized by enzymes to catalyze chemical reactions.
7. Proteins can act like BUFFER (a substance with a stable pH) in order to regulate the acid-base balance in the body.
8. KWASHIORKOR is a malnutrition deficiency that result from the insufficiency of dietary protein, resulting in swelling in the feet, legs, and stomach among other symptoms.
Answer:
Nitrogen in the reduced form is the major component of the three most important biological macromolecular structures: (i) proteins/polypeptides, (ii) DNA and RNA, and (iii) polymers of amino sugars.
There are four major classes of biological macromolecules - carbohydrates, lipids, proteins, and nucleic acids. Each are made up of different elements. Nitrogen is found in two of these macromolecules - proteins and nucleic acids.
Nitrogen is a naturally occurring element that is essential for growth and reproduction in both plants and animals. It is found in amino acids that make up proteins, in nucleic acids, that comprise the hereditary material and life's blueprint for all cells, and in many other organic and inorganic compounds.
Answer:
This question is incomplete as it lacks options, the options are:
A) What is the radius of each particle of the substance?
B) Does the substance contain more than one type of atom?
C) Was a chemical reaction necessary to create the substance?
D) What is the electrical charge of the particles of the substance?
The answer is B
Explanation:
In chemistry, an element is a substance made up of a single type of atom i.e. only one atom of the same type constitutes an element while a compound is a substance that contains two or more different elements. If a compound contains different elements, it means that a compound will certainly contain more than one type of atom.
According to this question, the best question to ask when Alyssa wants to differentiate between an element and a compound is: DOES THE SUBSTANCE CONTAIN MORE THAN ONE TYPE OF ATOM?
- If the answer is yes, the substance is a COMPOUND
- If the answer is no, the substance is an ELEMENT.
