According to this figure which of the following option is incorrect?

#Unit 5. Developmental Biology
  1. OTX is a general transcription factor, and B-catenin from the maternal cytoplasm is concentrated at the vegetal pole of the egg.
  2. These transcriptional regulators are inherited by the micromeres and activate the Pmar1 gene. Pmar1 encodes a repressor of HesC.
  3. In the veg2 macromeres, where activated Pmar1 protein represses the HesC repressor, the macromere specification and signaling genes are active.
  4. In the veg2 cells, Pmar1 is not activated and the HesC gene product shuts down the skeletogenic genes; however, those cells containing Notch can respond to the Delta signal from the skeletogenic mesenchyme.

Oxygen-Evolving Organisms Have two Photosystems that Operate in Series, explain by emerson that is the Photosystem I preferentially absorbs far-red light of wavelengths greater than 680 nm; photosystem II preferentially absorbs red light of 680 nm and is driven very poorly by far-red light; Another difference between the photosystems is that,

a.) Photosystem I produces a strong reductant, capable of reducing NADP+, and a weak oxidant

b.) Photosystem I produces a very strong oxidant, capable of oxidizing water, and a weaker reductant than the one produced by photosystem II

c.) Photosystem II produces a strong reductant, capable of reducing NADP+, and a weak oxidant

d.) Photosystem II produces a very strong oxidant, capable of oxidizing water, and a weaker reductant than the one produced by photosystem I
