Answer:
Hopefully this helps! If it doesn't, let evil.
Explanation:
In the absence of tryptophan, transcription of the structural genes will be reduced compared to a wild-type operon.
By digesting the food as grown into cells maybe. i am not 100%sure.
Answer:
Aerobic to lactic acid fermentation pathway
Explanation:
ATP, which is the usable form of energy in living cells, is obtained via a process called RESPIRATION. However, aerobic respiration requires a constant supply of oxygen to occur. Hence, during an intense exercise where the supply of oxygen is low, the muscle cell has to switch from the respiration pathway that requires oxygen to one that doesn't.
Fermentation is a kind of cellular respiration that does not require oxygen to occur. In the muscle cells of animals (humans inclusive), lactic acid is the product of the fermentation process, hence, it is called LACTIC ACID FERMENTATION. This means that the muscle cells, in a low supply of oxygen, will switch from AEROBIC to LACTIC ACID fermentation pathway.
Answer;
D.Carbon-based macromolecules are found in all life forms.
Explanation;
-Most molecules that make up living things are based on carbon atoms. The structure of a carbon atom allows it to form up to four covalent bonds. It can bond to other carbons or to different atoms.
-All organisms are made of four types of carbon-based molecules; carbohydrates, lipids, proteins, and nucleic acids. Carbohydrates are molecules made of carbon, hydrogen, and oxygen. Sugars and starches are both types of carbohydrates. These carbohydrates can be broken down to produce energy in cells. Some carbohydrates are part of cell structure in plants.
-Lipids are molecules that include fats, oils, and cholesterol. Lipids are nonpolar, so they do not dissolve in water. Like carbohydrates, most lipids are made of carbon, oxygen, and hydrogen atoms. Some lipids are broken down and used as energy in cells.
-Proteins are the most varied of the carbon-based molecules in organisms. There are many different types of proteins. They are involved in many different body functions including movement, eyesight, and digestion.
