grp 17
Explanation:
this should be the new periodic table:) grp 1 and 2 belongs to metal. grp 18 belongs to halogen which have full valence electron thus they are inert/ unreactive. thus the ans is grp 17. grp 17 are halogens which are non metals.
1) Carbon dioxide
The carbon atoms present in CO2 are used by the plant in the formation of the organic molecular group (sugar).
2) Chlorophyll
Photosynthetic pigments present in chloroplasts, responsible for absorbing light from wavelengths between blue and yellow and reflecting different shades of green
3) Oxygen
Oxygen is the end product of photosynthesis, the result of the breakdown process of water molecules.
4) Stomata
Stomates have the function of performing gas exchange between the plant and the external environment. This structure is also responsible for the perspiration of the plant.
5) Sunlight
Energy source for the process of transforming light energy into chemical energy
6) Glucose
Final product of photosynthesis. Molecule that will be used by the plant to maintain its vital functions.
7) Water
Oxygen source that will be released as a gas at the end of the process.
Answer:
permineralization replacing original cellulose of the wood.
Explanation:
Fish breathe by drawing water in their mouths and forcing it out of the body via a number of gill slits. The gill slits are rich in blood vessels, enabling the direct absorption of oxygen. While all fish have gills, some fish are also able to extract oxygen from the air via gulping.
Most fish have swim bladders that are permanently sealed, but other fish have swim bladders that can hold varying amounts of air. Salmon have open swim bladders, and they must gulp air at the surface to keep them full. Some fish, such as sharks, lack swim bladders entirely. This causes them to sink if they do not maintain forward motion.
Fish have fins that are adapted to their lifestyle. Some have evolved into long, barbed structures, suitable for defense. Other fish have fins suited for achieving great speed or for walking along the bottom of the ocean.
