Snapper overfishing
Explanation:
Coral reefs are becoming highly vulnerable due to increased anthropological exploitation of the ocean reserves. Overfishing, usage of non-selective fishing gears, fishing the spawning areas, fishing using nets etc all affect the coral reefs and the marine ecosystem. The coral reefs and the fish population are interdependent and overfishing greatly impacts both the factors.
Overfishing is the main reason for damage and decline in coral reefs. The snappers are carnivores and survive on eating other fishes which can be herbivores or omnivores. Snappers remain at the top of the food pyramid of the marine ecosystem. A reduction at the top level of the food pyramid will automatically disturb the lower level population and the energy flow between each cycle. A reduction in carnivores leads to increase in herbivores which in turn deplete the coral reefs. Coral reef is a habitat for many fish populations, and a reduction in the habitat will again reduce the overall population of fishes. A decrease in predator population will increase prey population.
Hyponatremia and decreased urine output are exhibited with syndrome of inappropriate secretion of antidiuretic hormone (siadh).
<h3>What is secretion of antidiuretic hormone (siadh)?</h3>
Syndrome of inappropriate secretion of antidiuretic hormone (SIADH) is a condition in which the body produces too much antidiuretic hormone (ADH). This hormone helps the kidneys control the amount of water the body loses through urine. SIADH causes the body to retain excess water. ADH is a substance that is naturally produced in an area of the brain called the hypothalamus. It is then released from the pituitary gland at the base of the brain.
There are many reasons why the body needs to produce large amounts of ADH. Common situations where ADH is (improperly) released into the blood when it shouldn't be produced include:
- During surgery General anesthesia
- Brain disorders such as trauma, infections and stroke
- Brain surgery involving the hypothalamus
- Pulmonary disorders such as tuberculosis, cancer, chronic infections and pneumonia
- Substance abuse
Rare causes include: There is a thing Pituitary
- Leukemia and cancer of the small intestine, pancreas and brain
- Psychiatric disorders

In meiosis, the chromosome pairs do the crossing over where there is an exchange of genetic material between them and because of it the
chromatids held together by the centromere are no longer the same.
Answer: Oxidation of Glucose,Glycolytic reactions
Explanation:
Pure culture can be prepared from a mixture of cultures by using the streak plate method. This enables the bacterial cells to be diluted to obtain a pure culture after many-folds dilution.
Pure culture is the one in which only one species, strain or clone of bacteria are grown. The pure culture enables to scientists to study in detail about its anatomy, lifestyle and potential uses or harms, without the interference of any other microbe.
Streak-plate method is the most commonly used technique in microbiology labs to isolate a single type of bacteria. It is performed by creating the smears of bacteria in zig-zag motion to dilute its concentration.
