How do the structures in the image above play a role in heredity?

• DNA produces genes which are types of cells located in the chromosome.

• Chromosomes contain DNA where the genes that store the information about our traits are located.

• Genes determine the type of DNA we will receive from our parents which is located on our chromosomes.

• Chromosomes produce DNA when reproduction occurs and from there genes are passed to the next generation.

Which of the following best explains the role of the Sun in driving ocean currents and wind patterns?

• The Sun plays a role in driving wind patterns but not ocean currents.

• 1. The Sun's gravity causes the Earth to rotate, creating wind patterns and ocean currents.

• The Sun’s cycling of water on Earth causes the ocean currents but plays no role in the wind patterns.

• The Sun's uneven heating of the Earth's surface causes the formation of wind patterns and ocean currents.
