Answer:

Added acid number 8 and acid 1 and 4 accumulated

Explanation:

Answer 2
Answer:

Final answer:

Krebs utilized radioactively labeled carbon atoms to track the metabolic process, and he observed that these atoms reappeared in the form of carbon dioxide which indicated a cyclic process. He further identified citric acid as a significant product of this cycle and noticed that certain intermediates constantly replenished despite the ongoing reactions, supporting the cyclic nature of the cycle.

Explanation:

Dr. Hans Adolf Krebs discovered the citric acid cycle, also known as the Krebs cycle or TCA cycle, through his extensive biochemical research. He utilized radioactively labeled carbon atoms (specifically in the form of acetate), which allowed him to track the carbon through the series of reactions in the cycle. When he observed that the labeled carbon atoms reappeared in the form of carbon dioxide, it indicated a cyclic mechanism at work. Furthermore, he isolated and identified citric acid as a major product of cellular respiration, connecting it directly to the cycle.

In addition, Krebs noticed that certain intermediates were replenished such that the amount remained constant despite the ongoing reactions, providing further evidence for the cyclic nature of the citric acid cycle. Overall, Krebs' investigation relied heavily on experimentation and direct observation to deduce the properties and functions of this crucial metabolic process--- a remarkable combination of biochemical research and cellular respiration.

Woodwinds and _____ are wind instruments. percussion strings keyboards brass

Answers

Answer:

Brass.

Explanation:

Wind instruments can be divided into two categories: wood and metal. However, it is the form of sound production that determines its classification and not the constructive material of the instrument. They are the horns, trumpets, trombones, tubas, saxophones and euphoniums.

This category includes wind instruments that produce sound by direct vibration of the performer's lips on a metal mouthpiece. All are made of metal or made of metal alloys and have a very powerful sound. The most important representatives of this group are the horn, the trumpet, the trombone and the tuba. They are all part of the orchestra and also of military bands.

The old instruments of this group had a smooth tube. Over time additional holes, wrenches and tubes called threads and pistons were added.

Brass. Trumpets, trombones, French horns, tubas, and baritones all fall under the brass category and all require air to be blown through them.

The concept of _____ divided the octave into 12 tones which helped to avoid unpleasant harmonies. counterpoint equal temperament imitative polyphony modes

Answers

Answer: Equal temperament

Explanation: This system divides the octave in 12 semitones related by the sequence Fₙ₊₁ = Fₙ*2^(1/12) (in frequency).

In the actual American notation, the 12 semitones are called:

A, A#, B, C, C#, D, D#, E, F, F#, G, G#.

This new intonation is very useful to avoid unpleasant harmonies, but none the less, it still sounds a little bit "off" when compared with just intonation (in the right key).

The concept is equal temperament
