Colt1911 [192]

Answer:

The correct answer is e. the passage of electrons from one energy-generating carrier to another

Explanation:

The electron transport chain is a series of proteins and organic molecules found in the inner membrane of the mitochondria. Electrons pass from one member of the transport chain to the next in a series of redox reactions. The energy released in these reactions is captured as a proton gradient, which in turn is used to form ATP in a process called chemosmosis.

These transport molecules, in the inner mitochondrial membrane, are reduced and oxidized, accepting electrons and transferring them to the next molecule, electrons descending from high energy levels to lower ones, that is, from one energy-generating carrier to another. When lowering to other levels, energy is released that will be used in the synthesis of ATP by oxidative phosphorylation.

Roman55 [17]

Answer:

A) rely on protection and resources supplied from the maternal plant.

Explanation:

The embryo is a structure formed after the fusion of the male gamete and female gamete. A diploid zygote is formed after cellular division forms the embryo in the female gametophyte and therefore is considered the diploid tissue.

The embryo requires the nutrients for growth and absorb them from the surrounding female gametophyte structure like endosperm in the angiosperm. The embryos grow and form the sporophytic structure.

Thus, Option-A is correct.

According to the biological species concept, a species is the population of organism in which the individual are able to interbreed with each other and also able to produce viable and fertile offspring.

Therefore here to determine whether polar bears and grizzlies are different species we have to get information that whether the F1 generation of grizzlies and polar bears is viable and able to produce their own offspring that means are F1 generation fertile. So the correct answer is e. I and II only.
