Which of the following statements regarding sudden infant death syndrome (sids) is correct? 1 certain cases of sids are predictable and therefore preventable.2 sids is most commonly the result of an overwhelming infection.3 most cases of sids occur in infants younger than 6 months.4 the cause of death following sids can be established by autopsy.

The correct statement is 3: "Most cases of SIDS occur in infants younger than 6 months".

Explanation:

1) Certain cases of SIDS are predictable and therefore preventable. FALSE. There aren´t predictable cases of SIDS because this syndrome does not present any symptoms that should be considered to prevent death. There is no specific treatment for SEDS. There are, though, some considerations to take such as prenatal attention, position while sleeping, clothing, checking their temperature, among others.

2) SIDS is most commonly the result of an overwhelming infection. FALSE. Researchers do not know the exact cause of SIDS, but studies have demonstrated that some babies showed irregular brain functioning that made it difficult to wake up while they could not breathe or the area that controlled breathing was affected;  differences in genes and their interaction with the environment that took them to death; irregular heart funtioning; respiratory infections.

3) Most cases of SIDS occur in infants younger than 6 months. TRUE. SIDS is one of the principal causes of death in infants between a month and a year old, occurring more frequently in babies between two and four months old.

4) The cause of death following SIDS can be established by autopsy. FALSE. The baby can be diagnosed after death with a complete investigation, which includes the examination of the body, examination of the death place, revision of illness before death, or any other health precedent.

c.) polymerase chain reaction

- "unlike the original dna fingerprinting method, dna profiling does not use restriction enzymes to cut the dna. instead it uses the polymerase chain reaction (pcr)? to produce many copies of specific str sequences. pcr is an automated procedure that generates lots of copies of a specific sequence of dna."

the answer would be..
