The right answer is vitamin C—citric acid.
Vitamin C or ascorbic acid protects against cellular aging, is essential for the immune defenses and increases the assimilation of iron of plant origin.
Citrate is a biological molecule found in all living organisms because it is involved in the Krebs cycle (or citrate cycle) to produce energy.
Many soil-dwelling bacteria produce molecules that can be naturally synthesized and kill other species of bacteria. What are these bacteria-killing molecules called antibiotics
Antibiotics are effective pills which can be usually safe. Although they are very helpful in fighting disease, antibiotics can actually be harmful. Important Facts About Antibiotic Safety: Antibiotics can cause side effects such as allergic reactions and severe and potentially life-threatening diarrhea caused by the bacterium Clostridium difficile (C. diff).
Antibiotics can also interfere with other medications you may be taking. Antibiotic side effects account for nearly one-fifth of emergency room visits. These conditions are the most common reasons for emergency room visits for children under the age of 18. Taking antibiotics you don't need unnecessarily exposes you to the drug's side effects and denies you the benefits.

Answer:
The correct answer is b. decreased genetic difference between the two populations
Explanation:
The gene flow between two population always reduce the genetic difference between the two population because it increases the homogeneity between the population.
If there is greater gene flow between the two populations genes will be shared and transferred between the individual of two population which will make the two gene pool to become more and more similar.
This will increase the fitness of both the population because more allele will add to the two populations. Therefore the correct answer is b.
Answer:
Explanation:
National Park Service has been keeping the native ponies on Ocracoke Island since the 1960s. It is believed that these ponies arrived and left by the ships. These ships required to lower their load thus they left the ponies on the Island. These ponies are known as Ocracoke ponies and also called as Banker ponies. These ponies share a link to old Spanish horses genetically. The unique characteristics of the ponies include one fewer lumbar vertebrae, greater bone density, short necks, wide foreheads, and one fewer rib.
