What is required for both the light-dependent and light-independent reactions to proceed? a. energy b. co2 c. water d. atp and nadph

A. energy

Explanation:

Photosynthesis is a process of carbohydrate synthesis by green plants. It is divided into two processes the light-dependent or light reactions and light-independent processes or dark reactions. Both the processes require energy and are inter interdependent. During light-dependent process, chlorophyll traps solar energy converts solar energy into ATP and NADPH molecules. The light-independent processes or dark reactions uses power (ATP and NADPH) to fix carbon dioxide into carbohydrate.

regulation of gene expression. gene expression can be regulated by various cellular processes with the aim to control the amount and nature of the expressed genes. these regulatory proteins bind to dna and send signals that indirectly control the rate of gene expression

explanation:

hey bro i looked it up on google the structure of the eye-spot in euglena viridie, e. ehrenbergii, and phacus pyriyorme is not as franzé haa described it. the so-called “crystal body” and “lens bodies” were not found in any of the individuals of the species examined by me. as earlier observers have stated, the eye-spot consists simply of a mass of pigment granules arranged in a single layer, and probably embedded in a protoplasmic framework, but the latter could not be seen, and its presence was only inferred from the fact that the pigment granules must be held together in some way, thd the eye-spot as a whole is capable of expansion, and that the pigment granules can be separated from each other.

hope this   and an i get brainlsiest
