Answer:
due to gmos we can expand the shelf life of many of our foods and prevent them from the harm of pests. You night be rhinking why not use pesticides? well, we did but eventually the pests became immune to the low dose of pesticide. over time we gradually increased our uses of pesticides. more commonly round up. this pesticide specifically was known for being a carcinogen. (something that causes cancer.) Genetically modifying a crop can severely decrease the amount of pesticides used for our crops and could also potentially drop the prices. for example, in hawaii during the 1940s to 1990s the ringspot viruses hit the hawaiian papaya harvest hard. this reduced the amount of papaya produced by 50 percent by 1993 and 2006. the ringspot virus nearly wiped out the entire crop. within 11 months, the hawaiian papya was saved. due to gmos of course. this is because scientists took genes from immune papayas which very rarelt occured (at the time) and injected it into many other papya plants. as the plants grew, new papaya was produced which was immine to ringspit virus. PAPAYA WAS SAVED!!!!

Answer:
The correct answers are:
1. closing
2. the ventricles and arteries,
3. a constricted trachea
Lub is the first sound of a heartbeat and is mentioned as S1. It is usually produced due to the closing of tricuspid and and mitral or bicuspid valves present between atria and ventricles.
Tricupsid is located between atrium and ventricle of the right hand side and mitral valve is located between atrium and ventricle of the left hand side. They prevent the back flow of blood from ventricles to their respective atria.
Dub, being the second sound is written as S2. It is produced due to the closing of pulmonary (located between right ventricle and pulmonary artery) and aortic valves (located between left artery and aorta).
These valves prevent the back flow of blood from arteries into the ventricles.
The time between the two sounds is often taken as the measure of the diastole i.e. ventricular filling.
Wheezing refers to a high-pitched sound produced when a person breathes, especially during exhale. It is caused by constriction of the airways or inflammation. It is considered as a symptom of various diseases such as asthma, COPD, allergies, bronchitis etc.
