Answer:
Keelboats have been used for exploration, such as during the Lewis and Clark Expedition, but were primarily used to transport cargo or settlers in the early 19th century. The process of moving a keelboat upriver was extremely difficult, though current dependent.The earliest keelboat seems to have been a skiff with a plank nailed the length of the bottom to make the boat easier to steer, but by about 1790 the keelboat had become a long narrow craft built on a keel and ribs, with a long cargo box amidships.
Explanation:
In order to prevent the development of lycopod sporangia, sporophylls structures should be removed.
A leaf that generates spores is called a sporophyll. Sporophylls are a type of diploid sporophyte that produce spores that, upon germination, will give rise to haploid gametophytes. In sporangia, which can appear in a variety of shapes in diverse plant species, the spores are born. The sporophylls themselves differ significantly in terms of both structure and appearance, and they may or may not resemble trophophylls, which are leaves that only perform photosynthesis to create carbohydrates and never spores. Sporophylls and trophophylls are both green and photosynthesize in more primitive plants like lycophytes and ferns, and they typically resemble one another quite a bit. The sporophylls and trophophylls of certain unusually primitive plants, like Equisetum, as well as more evolved plants, such seed plants, are quite distinct from.

Ruling out rival hypotheses, Findings consistent with several hypotheses
require additional research to eliminate these hypotheses. More five principles
of critical thinking are: (1.) Correlation vs. Causation, the fact that two
things are associated with each other doesn’t mean that one causes the other.
(2.) Replicability, a finding must be capable of being duplicated by
independent researchers following the same recipe. (3.) Occam’s Razor,
if two hypotheses explain a phenomenon equally well, we should generally select
the simpler one. (4.) Falsifiability, claims
must be capable of being disproved. (5.) Extraordinary Claims, the more a
claim contradicts what we already know, the more persuasive the evidence must
be before we should accept it.

Answer:
In 1 hour it will cover a distance of 15°
Explanation:
We know that for each rotation earth takes 24 hour
In 24 hour its travels 360° of rotation
We have to find how much we travel in 1 hour in degree
We know that 1 rotation = 360° which is completed in 24 hours
So distance traveled in 1 hour in degree will be = 
So in 1 hour it will cover a distance of 15°
