Scientists believe the smaller prokaryote in this example evolved into which organelle? Think about it! HINT: ATP and "Heterotrophic"
1. Golgi bodies
2. mitochondria
3. nucleus
4.chloroplasts
The endosymbiotic theory states that chloroplasts and mitochondria used to be free-linving bacteria that got phagocyted by another cell. The correct option is 2. Mitochondria.
What does the endosymbiotic theory state?
The endosymbiotic theory proposes that mitochondria and chloroplasts were once free-living bacteria that were phagocytized by another cell but not digested.
These bacteria got to adapt to their host, and both cells became interdependent.
Both organelles have many similarities with other free-living bacteria.
Chloroplasts probably derivate from cyanobacteria because both cells absorb sunlight, produce ATP, and organic molecules. Mitochondria derivate from rickettsias because they produce ATP in the same way by using the Krebs Cycle and Oxidative Phosphorylation.From the phagocytosis moment, these two cells became so dependant on each other, they could not survive without the other one.

We often do not think of gas in terms of having mass. The atmosphere is something we live in and breathe. In this experiment, we will investigate whether gas does truly have mass.
Hypothesis: If gas does indeed have mass, then different volumes of it will have a different mass. This could be demonstrated by using a simple balance and comparing the two different volumes, captured by means of balloons.
Materials needed:
two balloons of the same size
meter stick
string
paper clips
Procedure:
1. Suspend the meter stick from the middle in such a way as to be able to move the string to balance. See the diagram below.
2. Attach each balloon to either end of the meter stick, making the apparatus balance.
3. Blow up each balloon to different volumes, thus measuring out different volumes of gas.
4. Attach the balloons as shown in the diagram below using the paper clips. Be careful to attach the balloons in the same place as where the apparatus balanced.
5. Answer the following questions in the writing space provided in this assignment.
Did the suspended balloons balance?
If they did not, which balloon tipped the scale down?
Did your results validate the hypothesis?
Give an explanation for your results, including a discussion of how the data collected either validated, or disproved the hypothesis.
The suspended balloons did not balance. The bigger balloon tipped the scale down. And yes, it validated the hypothesis that gas does have mass, as the bigger balloon weighed down the scale.
Gases have mass. Gas particle gaps are completely empty. Chemical reactions can produce gases as a byproduct. Under some circumstances, bonding between gas atoms is possible.
Loosely packed molecules can be found in gases. Gases have weight because the molecules that make them up have mass. Because of this, a balloon with air inside weighs more than one with none.
After combining the vinegar and baking soda, one of the paper bags will be "poured" with gas from the pitcher, which will cause the scale to tip toward that end even though nothing actually was poured into the bag. It is demonstrated by this that gas has mass and is heavier than oxygen.
