The correct answer is (d) altered ecosystem.
The increase in the global temperature all over the world due to the harmful effect of green house gases is called global warming. The consequences of global warming can be defined as having an increase in growing seasons, changes in migration and loss of species. All the consequences mentioned here signifies altered ecosystem. The ecosystem consists of the plant and animal species that interact with the environment. Hence, global warming results in altered ecosystem.

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.
