Answer:
Euglena have diversed nutritional requirements. They are autotrophic when kept in light and heterotrophic when deprived of light.
The Euglena contains chloroplast in it to perform photosynthesis in the presence of light.
When the Euglena is kept in the dark it starts deriving energy from the organic matter around it and shows heterotrophic mode of nutrition.
When light will be provided to Euglena it will start resynthesizes its photosynthetic pigment and it will start perform photosynthesis.
Answer:
DNA is essentially a storage molecule. It contains all of the instructions a cell needs to sustain itself. These instructions are found within genes, which are sections of DNA made up of specific sequences of nucleotides. In order to be implemented, the instructions contained within genes must be expressed, or copied into a form that can be used by cells to produce the proteins needed to support life.
The instructions stored within DNA are read and processed by a cell in two steps: transcription and translation. Each of these steps is a separate biochemical process involving multiple molecules. During transcription, a portion of the cell's DNA serves as a template for creation of an RNA molecule. (RNA, or ribonucleic acid, is chemically similar to DNA, except for three main differences described later on in this concept page.) In some cases, the newly created RNA molecule is itself a finished product, and it serves an important function within the cell. In other cases, the RNA molecule carries messages from the DNA to other parts of the cell for processing. Most often, this information is used to manufacture proteins. The specific type of RNA that carries the information stored in DNA to other areas of the cell is called messenger RNA, or mRNA

Answer:
It is potential energy that can power ATP synthesis
Explanation:
Electron transport chain is considered the most important stage of the cellular respiration as it is the only stage during which a high amount of ATP is produced.
The electron transport through various protein complex where electrons lose its energy and are used to drive the outflow of the proton to the outside of the mitochondrial membrane.
When protons accumulate outside the membrane creates a proton gradient as a result of which the proton needs to enter the cell.
The protons enter through the ATP synthase where the potential energy of the proton is used to rotate the rotor and thus ATP is formed from the ADP.
Thus, the selected option is correct.

cell membrane, DNA and RNA, cytoplasm, and ribosomes
