The heat inside the Tupperware causes an increase in pressure and when enough pressure builds, the atoms need somewhere to go and the seal at the top is easiest to break, so the top blows off.<span />

Answer:
The correct answer is option 4. Parasympathetic division.
Explanation:
The parasympathetic division is one of the three divisions of the ANS or autonomic nervous system. It also helps in the rest system or digest system as it saves energy by slowing the heart pace by slowing the rate of contraction. This is performed with the help of nerve fibers that send signals.
Parasympathetic nerve division increases the intestinal and activity gland. This nerve division helps in relaxing the sphincter muscle in the GI tract.
Thus, the correct answer is option D.
<h2>DNA </h2>
Explanation:
1) Experiment done by Griffith:
- Griffith used two related strains of bacteria, known as R and S
- R bacteria were nonvirulent, meaning that they did not cause sickness when injected into a mouse whereas mice injected with live S bacteria developed pneumonia and died
- Griffith tried injecting mice with heat-killed S bacteria (that is, S bacteria that had been heated to high temperatures, causing the cells to die), the heat-killed S bacteria did not cause disease in mice
- When harmless R bacteria were combined with harmless heat-killed S bacteria and injected into a mouse, not only did the mouse developed disease and died, but when Griffith took a blood sample from the dead mouse, he found that it contained living S bacteria
- Griffith concluded that the R-strain bacteria must have taken up what he called a transforming principle from the heat-killed S bacteria, which allowed them to transform into smooth-coated bacteria and become virulent
2) Experiment done by Avery:
- Avery, McCarty and MacLeod set out to identify Griffith's transforming principle
- They began with large cultures of heat-killed S cells and, through a long series of biochemical steps progressively purified the transforming principle by washing away, separating out, or enzymatically destroying the other cellular components
- These results all pointed to DNA as the likely transforming principle but Avery was cautious in interpreting his results
- He realized that it was still possible that some contaminating substance present in small amounts, not DNA, was the actual transforming principle
3) Experiment done by Hershey and Chase:
- Hershey and Chase studied bacteriophage, or viruses that attack bacteria
- The phages they used were simple particles composed of protein and DNA, with the outer structures made of protein and the inner core consisting of DNA
- Hershey and Chase concluded that DNA, not protein, was injected into host cells and made up the genetic material of the phage
Answer:
It most suppoet tge impact theory.
Explanation:
The his impact theory or the big splash is one of the accepted theories of tge moon and it states that the moon or luna and explain the origin of the moon that a Mars sized object planetestimal collided with the the proto Earth and the ejecta debris joined together by gravitational force which is the moon and it's orbit the Earth. The moon have similar composition to the outer portion of the Earth.
