Answer:
Gastro-esophageal reflux disease is a disease in which the upset stomach causes re-flux of acid back to esophagus. This may produce highly uncomfortable feeling of chest burn that may last even for two hours. GERD can get worse after eating because more volume of acids are released by stomach on detection of food like fast food and food that have high protein content. Patients are recommended to lose weight because that loses the pressure on abdomen a decreases the chance of GERD. Head elevation is also recommended to keep the acid within the stomach. It is same in while sitting upright after eating is recommended by doctors. GERD symptoms may have some respiratory complications like lung inflammation and chest congestion due to the action of stomach acid. This may lead to asthama.
Cell division happens twice during meiosis. One starting cell can produce for gametes (eggs or sperm.) In each round of division, cells go through four phases called prophase, metaphase, anaphase, and telophase.
prophase During prophase the chromosomes become visible as paired chromatids and the nuclear envelope disappears. This phase includes reduction division, which is where the number of chromosomes is decreased from 46 (diploid) to 23 (haploid.)
metaphase This is where the 23 remaining chromosomes become attached to the spindle fibers.
anaphase During this phase, the chromosomes move away from each other to one or the other pole of the spindle fiber.
telophase In which the chromatids or chromosomes move to opposite ends of the cell and two nuclei are formed.
interphase This is a resting period.
