B. The oldest crust is closest to the mid-ocean ridge.
Answer:
Explanation: Members of Kingom Plantae are autotrophs, meaning they produce their own food via photosynthesis. They are multicellular organisms. On a cellular level, members of Kingdom Plantae have cell walls ( members of Kingdom Animalia lack cell walls in their cells, but have red blood cells instead)
We now know that they have unique physical, chemical, and genetic traits that set them apart from plants and other eukaryotes. For example, the cell walls of fungi are made of chitin, not cellulose. Also, fungi absorb nutrients from other organisms, whereas plants make their own food.
Carbon dioxide is a colorless and non-flammable gas at normal temperature and pressure. Although much less abundant than nitrogen and oxygen in Earth's atmosphere, carbon dioxide is an important constituent of our planet's air. A molecule of carbon dioxide (CO2) is made up of one carbon atom and two oxygen atoms. Carbon dioxide is an acidic colorless gas with a density about 53% higher than that of dry air. Carbon dioxide molecules consist of a carbon atom covalently double bonded to two oxygen atoms. It occurs naturally in Earth's atmosphere as a trace gas.
