If a balloon filled with air and sealed is kept in a deep freezer for a period of time, it will shrink in size. Determine the the best reasoning for this outcome.

Answers

Answer 1

Answer: The temperature of the air in the balloon will decrease. The cold makes the molecules move slower and they get closer together. This leads to a lower pressure inside the balloon. The pressure on the outside is higher than the inside and it pushes the balloon to shrink.

Answer 2

Answer:

CHOICES:

A) The air particles inside the balloon slow down due to lower thermal energy. As a result, fewer collisions take place per second and this leads to a lower pressure inside the balloon. The pressure on the outside of the balloon pushes the balloon to a smaller volume.

B) The air particles inside the balloon slow down due to lower thermal energy. As a result, the air particles become charged, attract to each other and take up a smaller volume. Therefore, the balloon shrinks.

Eliminate

C) The rubber latex of the balloon becomes colder and will resist stretching and push the air particles inward until the inside pressure equals the outside pressure and equilibrium is established.

D) The density of the air particles increases within the balloon causing some particles to escape out of the balloon. This leads to an increase in the particles and, thus, pressure outside the balloon. This causes the balloon to collapse.

Why are frogs said to have 2 lives

Answers

Amphibian means two-lives, Frogs began there lives in the water as eggs and then grow to tadpoles, when they are fully developed they live on land.

they start their life in water as a tadpole then they adapt to land and go through metamorphosis to become a frog

___________ leave the blood and enter tissues to fight off pathogens and invaders.a. Platelets
b. Capillaries
c. Red blood cells
d. White blood cells

Answers

The white blood cells are the ones who leave the blood and entertissues to fight off pathogens and invaders. The answer is letter D. They arenot platelets because platelets help the healing of wounds and prevent it frombleeding by forming blood clots on the wounded area. They are not red bloodcells because they carry oxygen all throughout the body organs. And they arenot capillaries because capillaries are the ones that transports the oxygenatedblood into the arteries.

3. The fact that the genetic code is universal suggests that:A. All organisms evolved from separate original ancestors.
B. Life forms have a common evolutionary ancestry.
C. Protein makes up the genetic material.
D. Evolution does not really occur.

Answers

Answer:

B. Life forms have a common evolutionary ancestry.

Explanation:

A. All organisms evolved from separate original ancestors.

-> We know this is not true. If organisms evolved from separate ancestors, they would have different genetic code.

C. Protein makes up the genetic material.

-> This was proven false in Hershey–Chase experiment.

D. Evolution does not really occur.

->This one's obviously false as speciation happens regularly.
