The molecule found in the nucleus of cells that forms a double helix is DNA (deoxyribonucleic acid). DNA carries the genetic instructions for the development, functioning, growth, and reproduction of all living organisms.
No, forms can exist in both organic and inorganic materials. Organic forms are typically found in living organisms, while inorganic forms can be observed in non-living structures such as crystals, rocks, and man-made objects. Both types of forms can exhibit various shapes, patterns, and structures.
The DNA molecule in a living cell is typically found within the cell's nucleus, packaged into structures called chromosomes. In some organisms, such as bacteria, the DNA may be found in a region called the nucleoid within the cell, which is not surrounded by a membrane.
No, DNA is an organic molecule because it contains carbon and is found in living organisms.
Water is the most abundant molecule found in living organisms. It is essential for life processes such as hydration, temperature regulation, and biochemical reactions.

Protonephridia are found in flatworms, such as planarians. These structures are responsible for excreting waste and regulating osmotic balance in these organisms.
The earliest life forms were likely simple single-celled organisms, similar to modern archaea or bacteria. These early life forms would have lacked complex structures and organelles found in modern-day eukaryotic cells.
A substance or molecule that forms in a chemical equation is a product. Products are the result of a chemical reaction between reactants, and they are found on the right side of a chemical equation.
Carbon is the fundamental element found in all living organisms. It forms the basic building blocks of life, such as carbohydrates, lipids, proteins, and nucleic acids. Carbon's unique bonding properties make it essential for the complex structures and functions of living organisms.
No, eukaryotes are not only found in multicellular organisms. They can also exist as unicellular organisms, such as protists and yeast. While many eukaryotes do form multicellular structures that can combine to create tissues, others live independently as single cells. Thus, eukaryotes encompass a diverse range of life forms, both unicellular and multicellular.
C6H12O6 is the organic compound. It is glucose, a common sugar molecule found in living organisms.
