Answer:
Explanation:
There are many examples of fossils found on separate continents and nowhere else, suggesting the continents were once joined. If Continental Drift had not occurred, the alternative explanations would be:
The species evolved independently on separate continents – contradicting Darwin’s theory of evolution.
They swam to the other continent/s in breeding pairs to establish a second population.

To relieve airway obstruction in infants, lay the baby face down along your forearm using your laps for support. Apply five quick, forceful blows at the baby's back with the palm of your hand.
If the object did not come out, turn the baby face up and give five quick down thrusts. Continue the back slaps and the chest thrust cycle until the baby recovers.
The animal prepares for the hibernation ahead of time gathering food and eating so that it can sleep for the extended period of time without leaving
the three kinds of nitrogenous wastes based on the energy required to synthesize them are arranged; Ammonia < urea < uric acid.
Nitrogenous wastes are the nitrogen compounds that organisms use to get rid of excess nitrogen. Ammonia, urea, and uric acid are the most common nitrogenous wastes that animals excrete. Protein metabolism generates all of these nitrogenous wastes.
Ammonia is the most toxic of these nitrogenous wastes, and it is the most common but requires the least energy. Urea is more harmful than uric acid, but it is less harmful than ammonia, reducing the amount of energy required to synthesize it. Uric acid is the least harmful, a non-poisonous particle with four nitrogen molecules. This is useful for birds and reptiles that lay hard eggs because it eliminates the most nitrogen, uses the least amount of water, and is not toxic. It also takes the most energy input.
