Explanation:
DNA is a nucleic acid molecule that is composed of nucleotides. The nucleotide is composed of four different types of nitrogenous bases, a phosphate group, and the deoxy-ribose sugar.
The DNA molecule is used by the organism to store the information of organisms for a long time. The nitrogenous base in the DNA codes for different types of amino acids in the organism which can form proteins. The proteins can perform various roles in the organism. The DNA molecule is transmitted through reproduction in the organism.
Answer:
The H+ ions moves outside.
Explanation:
The H+ ions moves outside the mitochondria of the cell if the concentration of H ions were higher inside the mitochondrion than outside environment of the mitochondrion in order to equalize the pH or H+ ions concentration of both inner side of mitochondria and outer side environment. This movement of H+ ions from a region of higher concentration to the region of lower through a semi-permeable membrane is known as osmosis which has a positive effect on the cell as well as organelles of the cell.
The nucleus during mitosis. Micrographs illustrating the progressive stages of mitosis in a plant cell. During prophase, the chromosomes condense, the nucleolus disappears, and the nuclear envelope breaks down. At metaphase, the condensed chromosomes
Answer:
Red blood cell arrives from the inferior vena cava into right atrium before it passes through the tricuspid valve into right ventricle. It then passes through the pulmonary valve into pulmonary artery before travelling through the lungs and back into the heart, this time the left atrium via the pulmonary vein.
