Answer:
The sun gets its energy from the process of nuclear fusion. This process occurs in the sun's core or interior, where temperature and pressure are extremely high. During most of the sun's life, energy comes from the fusion of hydrogen nuclei
Explanation:
Mitochondria - The mitochondria is referred to as the power house of the cell. Its main function if to produceenergy for cell by the process of cellular respiration. The energyproduced is ATP. Endoplasmic Reticulum - It is a network for transportation of certain substances in and out of the nucleus.
Answer:
Secondary level of protein structure
Explanation:
The proteins are formed of the monomer units called amino acids which bond with each other via peptide bond and form a linear peptide structure called the primary level structure of the protein.
The proteins to perform several functions in a cell undergoes structural conformation and attain the helical form called alpha helix due to the involvement of alpha carbon in bond formation and a pleated sheet called beta-pleated sheet due to the involvement of beta carbon. These structures are known as a secondary level of protein structure.
Thus, a Secondary level of protein structure is the correct answer.
