Explain the role of valence electrons and how they relate to the periodic table of elements?
myrzilka [38]

Explanation:

The valence electrons determine the group the elements belong in the periodic table. For example, the element sodium, Na, has a valence electron of one and so it belongs to Group 1 in the periodic table. Another example is Aluminium, Al, which has a valence electron of three and therefore it belongs to Group 3 in the periodic table.

Explain one adaptation that helps grasses succeed in grasslands
ehidna [41]

Answer:

Basal meristems

Explanation:

Meristems are the portion of plants able to generate any kind of new tissues. Therefore, the way plants keep their meristems protected is related to climate adaptation.

Grasslands tend to be arid ecosystems, so grasses have developed basal meristems, meaning they spend the dry season very close or under soil, where water evaporates slowlier than above surface, until wet season allows meristems to generate new stems and leaves.

This disposition is also useful in cases of fire and grazing, which are also frecuent in grasslands.
