The correct answer is: 2)The light-dependent reactions produce ATP and NADPH, which are then used by the light-independent reactions
The light-dependent reactions is one of the two successive phases that occur during photosynthesis (other is light-independent reactions). The light-dependent reactions use sunlight energy to make the energy storage molecule ATP and the reduced electron carrier NADPH. In the light-independent reactions (also called Calvin cycle), CO2 is absorbed and fixed in order to build three-carbon sugars (glyceraldehyde-3-phosphate) and this process is fueled by, ATP and NADPH from the light reactions.
Water is usually stored in the atmosphere
Answer:
- Both DNA, which stores genetic information and encodes protein sequences, and RNA, which is involved in the direct production of proteins, are nucleic acids.
- Nucleic acids always consist of a five-carbon sugar, a nitrogenous base, and one or more phosphate groups.
Explanation:
DNA and RNA are both made up of chains of nucleotides. They are responsible for holding, transmitting, and translating genetic information into proteins.
Nucleotides are made up of a 5 carbon sugar, (DNA is deoxyribose, RNA is ribose), a phosphate group, and a nitrogenous base. They are linked together by phosphodiester bonds. The sequence of nucleotides makes the DNA and RNA sequences unique and determines the structure and function of the encoded proteins
Answer:
A compound light microscope is a microscope with more than one lens and its own light source. In this type of microscope, there are ocular lenses in the binocular eyepieces and objective lenses in a rotating nosepiece closer to the specimen.
The scanning electron microscope (SEM) produces images by scanning the sample with a high-energy beam of electrons. As the electrons interact with the sample, they produce secondary electrons, backscattered electrons, and characteristic X-rays.
