cell theory
What does cell theory state?
That all living things are made of cells
How does cancer relate to mitosis?
Cancer relates to mitosis because it happens when mitosis goes out of control.
Why is the circulatory system important to all systems?
It’s important because it moves oxygen, nutrients, and waste to and from every other system which keeps the body working properly
Hoe does evolution affect species survival?
Evolution helps species survive by giving them traits that make them better suited to their environment.
Why do homologous structures matter?
they matter because they show species came from a common ancestor
What are the three principles of cell theory?
All living things are made of cells
cells are the basic unit of life
all cells come from pre-existing cells
What causes cancer cells to grow uncontrollably?
Failure of cell cycle regulation
What is the main purpose of body systems working together
To maintain homeostasis
What statement best defined evolution?
A change in population over time
Have the same structure but different functions
Which conclusion supports the idea that cells come from pre-existing cells
Cells divide to form new cells
Which statement best describes the difference between normal cells and cancer cells?
Normal cells divide in a controlled way, while cancer cells divide uncontrollably.
Which systems are primarily responsible for regulating other body systems?
Nervous and endocrine
What is the primary source of variation that drives evolution?
Genetic variation
Why are vertebrate forelimbs often used as examples of homologous structures
Because they have similar bond arrangements across species
Why are cells considered the basic unit of life?
They can carry out all life processes
Mutation that interfere which process are most likely to lead to cancer?
Cell cycle regulation
What will most likely happen if one body system fails to function properly?
Other body systems may be disrupted
How does evolution influence species survival?
By producing adaptations that improve survival, and reproduction.
Which conclusion can you make when two species have homologous structures
They share a common evolutionary history
Which observation would challenge the cell theory?
A living thing exists that is not made of cells
How does cancer relate to mitosis?
Cancer results when mitosis is no longer regulated.
how do the nervous system and endocrine work together to maintain homeostasis?
They regulate responses and coordinate body functions
Why does evolution occur in populations rather than individuals?
Genetic changes accumulate over generations
Why are birds wings and dogs front legs considered homologous
Because they have a similar bone pattern
