Ans.
Lipids are a class of biomolecules, made up of fatty acids and fatty acid derivatives. Lipids are non-polar, water insoluble organic compounds, which include fats (triglycerides), steroids, phospholipids, and natural oils. Lipids play role in different functions, such as in membrane synthesis (phospholipids), energy storage (fats), and signalling (steroids).
Thus, the correct answer is option) 'lipids.'
Hydrogen bonds are the forces that hold two DNA strands together in a double helix.
Deoxyribonucleic acid, also known as DNA, is made up of two lengthy strands that loop around one another to form a double helix. The nitrogenous bases of the DNA's nucleotides form hydrogen bonds with one another, holding the two strands together.
The four nucleotide bases adenine (A), thymine (T), cytosine (C), and guanine (G) make up DNA. Adenine and thymine make hydrogen bonds, and cytosine and guanine do the same. Adenine always couples with thymine, and cytosine always pairs with guanine, forming unique and complementary hydrogen bonds.

The bonding forces between two DNA strands in a double helix are hydrogen bonds that occur between the base pairs. DNA bonding hold the two strands together, enabling the DNA double helix to act as the stable carrier of genetic information.
The bonding forces between two DNA strands in a double helix are known as hydrogen bonds. These bonds occur between the base pairs in the DNA sequence. For each base pair, adenine (A) bonds with thymine (T) through two hydrogen bonds, and guanine (G) bonds with cytosine (C) through three hydrogen bonds. These hydrogen bonds are what hold the two strands of the DNA double helix together, allowing it to function as the stable carrier of genetic information.

Answer:
ITS (D) All of the above.
Explanation:
The trait causes a change in the environment surrounding the organism.
The trait decreases the number of genes in the body cells of the organism.
The trait is due to the genetic code present in the organism’s gametes.
