What was the biggest threat faced by the corps of discovery during its crossing of the Rocky Mountains?
The biggest threat faced by the Corps of Discovery during their crossing of the Rocky Mountains was harsh weather conditions, especially snowstorms and freezing temperatures. This made travel difficult and dangerous, putting the expedition at risk of hypothermia and getting lost in the rugged terrain.

What mountain ranges did Lewis and Clark Corps of Discovery travel over?
The Lewis and Clark Corps of Discovery traveled over the Rocky Mountains and the Bitterroot Range during their expedition in the early 19th century. These mountain ranges presented significant challenges for the explorers as they journeyed westward.
What mountain ranges did the corps of discovery travel over?
The Corps of Discovery, led by Lewis and Clark, traveled over the Rocky Mountains during their expedition to the Pacific Ocean in the early 1800s. They also crossed the Bitterroot Range, a sub-range of the Rockies, on their journey.
What landforms did Lewis and Clark run in to?
Lewis and Clark encountered a variety of landforms during their expedition, including mountains (Rocky Mountains), rivers (Missouri and Columbia River), plains (Great Plains), forests (Pacific Northwest), and canyons (Hells Canyon). They also faced challenges crossing the rugged terrain of the American West.
Are the Ozark mountains older than the Rocky Mountains?
Yes, the Ozark Mountains are older than the Rocky Mountains. The Ozarks formed around 300 million years ago during the Alleghenian orogeny, while the Rocky Mountains started forming around 50 million years ago during the Laramide orogeny.
Where three mountain ranges did the pioneers cross?
The pioneers crossed the Appalachian Mountains, the Rocky Mountains, and the Sierra Nevada Mountains during their westward expansion in the United States.
What mountain ranges did Lewis and Clark Corps of Discovery travel over?
The Lewis and Clark Corps of Discovery traveled over the Rocky Mountains and the Bitterroot Range during their expedition in the early 19th century. These mountain ranges presented significant challenges for the explorers as they journeyed westward.
Scientist who discovered crossing over?
The scientist who discovered crossing over in genetics was Thomas Hunt Morgan. He conducted research with fruit flies in the early 20th century, which led to the discovery of genetic recombination through crossing over during meiosis. This breakthrough provided important insights into genetic variation and inheritance.
When does crossing occurs in meiosis?
Crossing over occurs during Prophase I.
What happens during crossing?
Crossing over is the process in which babies are made.
Is crossing over a process that occurs during mitosis or meiosis?
Crossing over is a process that occurs during meiosis.
Does crossing over occur during mitosis?
No, crossing over does not occur during mitosis. Crossing over is a genetic process that happens during meiosis, specifically during prophase I, where homologous chromosomes exchange genetic material. Mitosis is a different type of cell division that does not involve crossing over.
Can crossing over occur during mitosis?
No, crossing over does not occur during mitosis. It is a process that happens during meiosis, specifically during prophase I. During crossing over, genetic material is exchanged between homologous chromosomes, leading to genetic variation in offspring.
Where does crossing over occur in the process of mitosis?
Crossing over occurs during the prophase I stage of meiosis, not during mitosis.
At what stage of mitosis does crossing over occur?
Crossing over occurs during the prophase I stage of meiosis, not during mitosis.
When does the process of crossing over start and end during genetic recombination?
The process of crossing over starts during prophase I of meiosis and ends during metaphase I.
What results from the process of crossing over during prophase I?
During crossing-over, chromosomes of a homologous pair breaks and exchange genes.
Does crossing over occur during prophase 2 of meiosis?
No, crossing over occurs during prophase 1 of meiosis, not prophase 2.
