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.
Answer:
A- A one-tailed test
Explanation:
A one-tailed test is a statistical test that shows the sample mean would either be higher or lower than the population mean. It creates a relationship in a single direction such that the critical area is either greater or less than a stated value but not both. In a one-tailed test, null and alternative hypothesis have to be stated as if the tested sample is in a one-sided critical area, the alternative hypothesis is accepted.
In this scenario, the researchers' hypothesis take either > 6 or < 6 as the stated value. The result can only go in either of both direction, not both.
