Answer:enzymes
Explanation:during digestion, food is broken down by chewing in the mouth.enzymes also acts on foods to reduce them into simpler constituents.enzymes acts on food in the mouth, stomach, intestine etc.
Enzymes that acts on proteins helps to break the peptides bonds present in proteins.they break up the polypeptide chains into amino acids .An example is trypsin .the conditions necessary for these enzymes to acts may be specific.some require acidic environment while others require basic environment.pepsin for example requires stomach hydrochloric acid to be converted from it's inactive form, pepsinogen.
The resultant Amino acids are then absorbed in the small intestine
Answer:
B. It was necessary that each of the two phage components, DNA and protein, be identifiable upon recovery at the end of the experiment.
Explanation:
Hershey and Martha Chase used radiolabeled the DNA of some of the bacteriophage cells with phosphorus (32P). They radiolabeled the sulfur (35S) of the coat protein in the second batch of the phage cells. They infected some of the bacterial cells with phage having radiolabeled DNA while the other <em>E. coli</em> cells were infected with the phage carrying radiolabeled coat protein. This allowed the clear identification of the radiolabelled molecule (DNA or protein) present in the host cell.
They observed that the <em>E. coli </em>cells infected with phage having radiolabeled DNA exhibited the radioactivity while the other batch of the host cell did not show it.
Answer:
The following are accurate about earthquakes which occur during the formation of a chain of Islands and seamounts by hotspots:
- Earthquakes occur along fault lines within volcanoes formed by the hotspot.
- Earthquakes occur along fault lines during plate movements.
- Earthquakes occur when Earth’s crust bends under the weight of islands formed by the hotspot.
Explanation:
C. S waves travel through solids or very dense, glassy liquids. P waves travel through solids, liquids, and gasses.
Sunlight energy source does not use a turbine in order to generate electricity.
<h3>Which type of energy resource does not use a turbine to generate electricity?</h3>
Sunlight is a type of energy resource does not use a turbine to generate electricity. Solar photovoltaic systems have Solar photovoltaic cells that convert sunlight directly into electricity.
So we can conclude that sunlight energy source does not use a turbine in order to generate electricity.
