Answer:

Plant cells having chloroplasts suggests that they come from a specific species of prokaryotes: cyanobacteria.

Explanation:

The endosymbiosis theory explains that <u>eukaryotic cells</u> (both plant and animal cells) <u>come from a common ancestor: prokaryotes</u>. Chloroplasts and mitochondria have outer phospholipid bilayer membranes and circular DNA molecules like prokaryotes have.

It is believed that ancient bacteria were captured by other cells in the past and thus they became eukaryotic cells.

Cyanobacteria are prokaryotes with the capacity to do photosynthesis as plant cells do.

sasho [114]

Given:

The solution decreased by \dfrac{9}{8} ounces every hour for 5 hours.

Remaining solution at the end of the experiment = \dfrac{99}{8} ounces.

To find:

The initial amount of solution.

Solution:

Let the initial amount of the solution be x.

The solution decreased by \dfrac{9}{8} ounces every hour for 5 hours.

Total decreased amount  =\dfrac{9}{8}\times 5

                                          =\dfrac{45}{8}

Initial amount = Remining amount + Decreased amount of solution.

x=\dfrac{99}{8}+\dfrac{45}{8}

x=\dfrac{99+45}{8}

x=\dfrac{144}{8}

x=18

Therefore, the initial amount of solution is 18 ounces.

Does a sunbird benefit the plant from which it drinks nectar?
Airida [17]
I believe the sunbird would benefit the plant because it would pollinate them. Going from flower to flower, pollen would get stuck on it's feathers and it would pollinate other flowers, like a bee.
