Answer:

For the given question the correct answer out of the four given options is

option A) It will oxidize the electron carrier NADH

Explanation:

In Electron Transport Chain, abbreviated as ETC, to produce energy, four protein complexes helps in the oxidation of FADH_{2} and NADH. This energy is required in ETC to produce ATP. Here, the electron carriers are NADH and  FADH_{2}. The electron movement through these 4 proton layers results in the driving of electrons in between the membrane spacing into the cytosol which in turn results in occurrence of negative charge in the matrix and equal positive charge the inter-membrane spacing.

Due to the charge difference, electro-chemical gradient, responsible for synthesis of ATP is developed.

What similarities, if any, do you think exist between a human’s reproductive cycle and the life cycle of a fern? What difference
ipn [44]

Answer:

Plant Reproduction and Life Cycle. The life cycle of a plant is very different from the life cycle of an animal. Humans are made entirely of diploid cells (cells with two sets of chromosomes, referred to as ''2n''). ... Plants, however, can live when they are at the stage of having haploid cells or diploid cells.

Explanation:

In an animal life cycle, male and female parents each create sex cells (sperm and eggs) that unite to form a fertilized egg and develop into an offspring organism. Plants, likewise, have sperm and eggs in their life cycles, but these are produced by an intermediate stage between the adult and the offspring.
