Answer:
A
Explanation:
because the crops will not grow with herbicide
Ribosomes, mitochondria, ER and chloroplast.
Answer:
The nervous system is stimulated from the environment, through sensory receptors. A stimulus is any form of energy that can be detected by the body. ... Animals normally only respond to stimuli which they select; they filter out certain stimuli that surround them, and react to others they choose to accept.
1. Our results showed that test tube B contained end products of protein digestion, meaning that the isolated enzyme has the ability to break down protein. The end products of protein digestion include small polypeptides, dipeptides, and amino acids. In general, test tube B will contain the building blocks of proteins, which are the amino acids.
2. The two test tubes were placed in a hot water bath at 37oC. This is because the enzyme studied is a human enzyme and it works best at the human body temperature, which is approximately 37oC.
Enzymes are biological catalysts, which means that they accelerate chemical reactions. As a result, an enzyme's activity is greatly affected by temperature. Every enzyme, depending on each function and origin, has a specific range of ideal temperature conditions. If the temperature rises above the maximum accepted, then the enzyme denatures and loses its structure.
3. If the enzyme studied was added in a tube containing starch instead of proteins, then nothing would happen. This is because the enzymes are highly specialized and have very specific actions. It has been proved that this enzyme's activity involves the digestion of proteins.
Starch is a polysaccharide produced by plants, this means that starch is a carbohydrate. Given that starch is not a protein, it will not be digested by the enzyme. An enzyme digesting proteins, will not have any effect on carbohydrates.
4. The smaller molecules which are the result of the digestion happening in the digestive system are absorbed by the human body. More specifically, the products of protein digestion are absorbed by the intestine and then transported into the bloodstream. From the blood, they are then absorbed by other tissues.
After they are absorbed, they are used to build muscles or other compounds which can produce energy.
Answer:
1: Chemical Energy
2: Kinetic Energy
3: Electrical Energy
4: Mechanical Energy
Explanation:
1: The energy held in food is called <em>chemical energy. </em>It is a form of <u>potential energy</u> held within chemical bonds between atoms.
2: When flowing water is captured and turned into electricity, it is called hydroelectric power or hydropower. There are several types of hydroelectric facilities; they are all powered by the <em>kinetic energy of flowing water</em> <u>as it moves downstream.</u>
3: The power for lights and stuff is <em>Electrical</em><em> </em><em>Energy</em><em>,</em> ofc :]
4: The <u>chemical energy in the food</u> gets changed into the <em>mechanical energy</em> of <u>moving muscles.</u>
<u>Hope</u><u> </u><u>this</u><u> </u><u>helps</u><u>!</u><u>!</u><u> </u><u>:</u><u>D</u>
