Tryptophan self-controls its synthesis. If we have a large amount of tryptophan in the sense that it exceeds, tryptophan would act as a co-repressor which prevents synthesis of more enzymes for its production. Hope this answers the question.
Answer:
The microscope is an instrument used for the visualization of the cell and its other component. Different types of microscope are compound microscope, electron microscope and binocular microscope.
The adjustment of the slide is important to visualize the focused object. A proper source of light is required to focus the image. At high magnification, the fine focus control is used for the adjustment. At 100 X the oil is used to visualize the object.

Answer:
The Galapagos cormorant has vestigial wings that don't help it to fly or swim, though the birds still dry them off in the sun after they get wet, just as if they would if they still could use them to fly. This species diverged into a flightless bird about 2 million years ago.
Explanation:
Answer:
1) Binds soil particles into aggregates and improves the water holding capacity of soil.
2) When carbon dioxide dissolves in seawater, most of it becomes bicarbonate ions and hydrogen ions. This increase in hydrogen ions is what decreases the pH.
3) Carbon dioxide (CO2) and other greenhouse gases act like a blanket, absorbing IR radiation and preventing it from escaping into outer space. The net effect is the gradual heating of Earth's atmosphere and surface, a process known as global warming.
Without greenhouse gases in its atmosphere , the Earth would be much colder on average than it is now. Greenhouse gases: absorb energy transferred as infrared radiation from the Earth's surface. release infrared radiation in all directions, which keeps the Earth warm.
