Answer:
Correct question= <em>What does the history behind the elucidation of secondary structure of DNA tell you about the role of the scientific community in advancing science? Were Watson and Crick solely responsible?</em>
Explanation
The earlier discovery of nucleotide sequence and base pairing by Levene formed the basis of later discovery and formulation of double Helix DNA structure by Waston and Crick. Thus Levene work contributed to discovery of DNA double helix structure of Waston and Crick
In addition earlier work of Franklin on X-ray crystallography data, and comprehensive research on biochemical analysis of ,molecular proportion of nucleotide by Chargaff, were another supporting bedrock on which Waston and Crick built their discovery of double helix structure of DNA.
Evidently most scientific discoveries were usually arrived at from the earlier work or discoveries, and rarely in isolation.

Explanation:
In the united states, tuberculosis is increasing in frequency due to homelessness and other diseases.
Tuberculosis (TB) is a bacterial infection spread through inhaling tiny droplets from the coughs or sneezes of an infected person. It mainly affects the lungs, but it can affect any part of the body, including the tummy (abdomen), glands, bones and nervous system.
TB is a potentially serious condition, but it can be cured if it's treated with the right antibiotics.
Typical symptoms of TB include:
- a persistent cough that lasts more than 3 weeks and usually brings up phlegm, which may be bloody
- weight loss
- night sweats
- high temperature
- tiredness and fatigue
- loss of appetite
- swellings in the neck
TB that affects the lungs (pulmonary TB) is the most contagious type, but it usually only spreads after prolonged exposure to someone with the illness. In most healthy people, the body's natural defence against infection and illness (the immune system) kills the bacteria and there are no symptoms.
Sometimes the immune system cannot kill the bacteria, but manages to prevent it spreading in the body. You will not have any symptoms, but the bacteria will remain in your body. This is known as latent TB. People with latent TB are not infectious to others.
If the immune system fails to kill or contain the infection, it can spread within the lungs or other parts of the body and symptoms will develop within a few weeks or months. This is known as active TB.

Answer:
Complex Carbohydrates
Explanation:
There are different types of macromolecules and they all have different purposes, but for a marathon carbs, specifically, complex ones would be best. This is because carbs are the main source of energy for the body. Additionally, unlike proteins, they allow for long-term energy; so you could run an entire marathon without running out of energy.
Three essential human components of athletic competition are
the following; sports officials, coaches and the participants. It is because
these three are important to keep an athletic competition from going or to
continue.
