How has the fertilization process of seed plants adapted to dry terrestrial conditions? a. they evolved fruit which are wet and keep the seed hydrated b. stomata close to prevent water loss c. the pine needle has thicker skin, to retain water and a needle-like shape that reduces leaf area d. the evolution of a pollen tube eliminated the need for water in the transfer of sperm to the egg submit for grading save and finish later?

The main advantage of Spermatophyta, seed plants (Gymnosperms and Angiosperms) is the evolution of the seed which, unlike spore-producing plants, was not limited to wet environments. Pollen grains are male gametophytes (sperm) which are protected from desiccation and can reach the female organs without dependence on water. The sperm is transferred from the pollen through the pollen tube: an extension of a cell within the pollen grain. The process is called pollination.

sulfur dioxide

explanation: acid rain is caused by a chemical reaction that begins when compounds like sulfur dioxide and nitrogen oxides are released into the air. these substances can rise very high into the atmosphere, where they mix and react with water, oxygen, and other chemicals to form more acidic pollutants, known as acid rain.
