Roots of the gametophyte spores develop

Answer:

The correct answer is option D-the underside of the sporophyte.

Explanation:

Ferns are pteridophytes which evolved earlier than the flowering plants. They do not produce seeds and reproduce through spores.

These spores are usually present on the underside of fern leaf also called "fronds" in sporophytic structures called sori. When these spores are ripened they are released from the capsule which germinates to produce prothallus, a gametophyte from which gametes are produced.

Thus, option D-the underside of the sporophyte is the correct option.

What makes nekton swimming abilities different from plankton and benthos
Nitella [24]

Answer:

The nektonic organisms are those marine organisms that are found in almost every depth. These can move freely from one place to another in the ocean body due to its ability to swim. For example, Turtles, sharks, Fishes, and dolphins.

The planktonic organisms are passive swimmers, as they can move along with the ocean currents and are mostly found in the upper portion of the ocean body. For example, Diatoms and Rotifers.

The benthos is the bottom-dwelling organisms that cannot swim. For example, Bivalves, Corals and Sponges.

The nektonic organisms are different from the planktons and the benthos because the nektons can easily swim. They are constructed with such body parts that allow them to swim and migrate from one region to another region within the ocean water body. Whereas the planktons and the benthos cannot migrate easily and are considered as sessile organisms.

Is the reduced form of cytochrome c more likely to give up its electron to oxidized cytochrome a or cytochrome b, why? Provide a
Vadim26 [7]

Answer:

The reduced form of cytochrome c more likely to give up its electron to oxidized cytochrome a having a higher reduction potential.  

Explanation:

Electrons from NADH and FADH2 flow spontaneously from one electron carrier of the electron transport chain to the other. This occurs since the proteins of the ETC are present in the order of increasing reduction potential. The reduced cytochrome b has lower reduction potential than cytochrome c1 which in turn has a lower reduction potential than the cytochrome c.

Cytochrome c is a soluble protein and its single heme accepts an electron from cytochrome b of the Complex III. Now, cytochrome c moves to complex IV which has higher reduction potential and donates the electron to cytochrome a which in turn passes the electrons to O2 via cytochrome a3.
