The correct answer is option D) Water is polar and the positive and negative ends of the molecule attract each other.

The water is a polar molecule, and forms a hydrogen bonding with the other water molecule. In the liquid state, the molecules of the water is in random motion, and the bond between the water molecules are continuously formed and deformed.

In the ice, the hydrogen bond between the water molecules become more stable, due to this, the molecules arrange themselves in a hexagonal pattern. Due to this arrangement, the allover space occupied is expanded. Hence, the ice is expanded than liquid water.

How does recombination contribute to offspring diversity?A. It modifies chromosomes to generate new alleles of genes that code f
omeli [17]

Answer: D. It yields chromosomes that contain both maternal and paternal DNA.

Explanation:

The recombination or crossing over is a genetic process. It takes place during the Prophase I of meiosis. The homologous pair align and held together by synapsis. This results in the mixture of genes combination formed from both parents that can be represented as a single chromosome.

If the recombination do not occur then each chromosome will be either 100% maternal or paternal. Thus recombination assures the recombinant chromosomes which consists of genetic material from both parents. Thus the genetic diversity of offspring increases.

ipn [44]

Answer:

Photosynthesis is the process where green plants synthesis energy using the energy of the sun, carbon dioxide and water.  Photosynthesis is very important to life it keeps most plants alive (autotrophs), and heterotrophs eat autotrophs to help them het energy. An autotroph is an organism that synthesis its own energy and heterotroph is an organism that gets it energy by digesting other organisms.
