Answer:

b

Explanation:

<em>The average speed of an object is the sum of the distance traveled by the object relative to the total time taken to cover the distance</em>. In other words,

<em>Average speed = total distance traveled/total time taken</em>

In this case, the total distance traveled by the runner = 26.2 miles while the total time taken = 3 hours and 15 minutes

60 minutes = 1 hour

15 minutes = 0.25 hours, hence

3 hours 15 minutes = 3.25 hours

Average speed = 26.2/3.25

                          = 8.0615 miles/hour

                            = 8.1 miles/hour

<em>The correct option is b.</em>

The gametophyte is green and nutritionally independent in
aev [14]

Answer:

The gametophyte is green and nutritionally independent in mosses, liverworts, and fern.

Explanation:

The gametophyte is the sexual stage of growth in plants and algae.

During this stage, there is production of reproductive organs which produce sex cells.

During this stage, the gametophyte is independent since it relies fully on itself for food production.

The presence of chlorophyll enables this independence.

The gametophyte produces its own food through photosynthesis.
