Answer:
A) Spore capsules
Explanation:
Ferns produce spore capsules contained in the sporangium (plural: sporangia), a structure localized on the undersides of the leaves. Moreover, the sporangia are borne in clusters known as sori (singular sorus). The spores are single reproductive cells that, when mature, are released from the sporangium to germinate on soil and produce new ferns. In a fern sporangium, the maximum number of spores is 64, although this number depends on the species.

Answer:
Average annual temperature in US cities would range between 50-70 degrees Fahrenheit
Explanation:
There are several factors that can influence the temperature of city in general. Higher altitude has a lower temperature because it has less air density and absorbs less sunlight. The city latitude coordinate also determines how much sunlight they will get. The closer the city to the equator, the more sunlight they can get.
Distance to the sea will influence the rate of rainfall and also influence temperature. Ocean currents can move hot water from other regions too.
