What is a chromosome called when it gets lost during mitosis?
" gets lost "I think you are describing a nondisjuction event where the chromosomes are not properly pulled apart to their proper positions by the mitotic spindle.
What is the role of spindle fibers in mitosis?
They pull the sister chromatids apart.
What means torn apart by wind?
'Fracto' means 'torn apart by wind.'
What term best describes continental drift?
Continental Drift is the name of a theory, developed by German meteorologist and geologist Alfred Wegener (1880-1930), asserting that parts of the earth's crust are slowly drifting on top of a liquid core. Wegener hypothesized that 200 million years ago, the earth was comprised of one great supercontinent, containing all of earth's land masses. He called the supercontinent "Pangaea," which means "all the land" in Greek. According to Wegener, Pangaea broke apart during the period bounded by the Jurassic and Cretaceous periods, to the point where the super land mass was finally separated into the distinct land masses we now recognize as modern-day continents. Wegener's theory of continental drift is published in his 1915 work entitled, "On the Origin of the Continents and Oceans."
What duplicated chromosomes are pulled apart during the fourth stage of mitosis called?
Before they are pulled apart they are called sister chromatids. Once they are pulled apart they are called chromosomes.
As hypothesized by Alfred Wegener what is the history of Earth's continents?
They were joined together, then drifted apart to their current positions
What is the supercontient that later broke apart into the seven continents found on Earth today?
The supercontinent that broke apart into the seven continents found on Earth today is called Pangaea. This breakup occurred over millions of years through the process of plate tectonics, resulting in the continents drifting apart to their current positions on the planet.
Who came up with the theory of Pangaea?
The theory of Pangaea was proposed by Alfred Wegener in 1912. He suggested that the continents were once joined together before breaking apart and drifting to their current positions.
What did Wegener called his theory of moving continents?
Alfred Wegener called his theory of moving continents "continental drift." He proposed that Earth's continents were once joined together in a single supercontinent called Pangea, which later broke apart and drifted to their current positions.
Who originated the theory of Pangaea?
The theory of Pangaea was originated by Alfred Wegener, a German meteorologist, and geophysicist in the early 20th century. He proposed that the continents were once connected in a supercontinent that he named Pangaea, which later broke apart and drifted to their current positions.
What did Wegener think caused the Continents to spread apart?
An earthquake.
What did wegener think the force was that was moving the continents apart?
volcanos
What did Alfred wegener believe that all of the continents were originally what?
Alfred Wegener believed that all of the continents were originally part of a single supercontinent called Pangaea, which existed about 300 million years ago. He suggested that over time, the continents drifted apart to their current positions through a process he called continental drift.
What name did Alfred wegener gave his supercontinent?
Alfred Wegener named his supercontinent "Pangaea," which means "all lands" in Greek. He proposed the concept of Pangaea in his theory of continental drift, suggesting that all continents were once connected as one large landmass before drifting apart to their current positions.
Who believed the continents were once connected but drifted apart?
Alfred wegener
What did Wegener think happened to Pangaea?
That it split apart into the current continents.
What did Alfred Wegener therize?
Alfred Wegener theorize that all the continents were once joined together in a single landmass and have since drifted apart.
