Answer:
Ginkgophyta
Explanation:
Gymnosperms are seed-producing plants with six phyla: Cycadophyta, Ginkgophyta, Gnetophyta, Pinophyta (Coniferophyta), Pteridospermales and Cordaitales.
Ginkgophyta is a phylum with a single living species-Ginkgo biloba.
Pteridospermales and Cordaitales phyla are now extinct.
Pinophyta (Coniferophyta) is the largest phyla of the Gymnosperms which includes pines, cypresses and relatives.
Answer:
The number of successful collisions can only be calculated for gases, so collision theory can only apply to gases. Collision theory helps scientists predict a rate constant, which can be used in a mathematical formula to help scientists determine reaction rates.

Answer:
E
Explanation:
All of the actions play a role in conserving energy. Purchasing local foods reduces the need for transportation, power strips keep a steady energy source, washing with cold water removes the need for a heater (which uses energy), and shorter showers have the same effect as stated before.
When an automotive battery is fully charged, the sulfuric
acid and water mixture will have a specific gravity of about 1.3. Specific
gravity is actually the difference in the weight of water in comparison to a specific
fluid. It is measured by a hydrometer. The amount of charge in the battery is
normally measured by the specific gravity of the battery. The specific gravity
of water is 1 and anything less than one is considered less dense while
anything that has a specific gravity of more than 1 is considered more dense
than water.
