important ideas
Why does the new male lion want to get rid of the previous male lion's cubs?
He doesn't want to carry another male lion's alleles.
metabolism
how food breaks down and turns in to energy
total energy cost
(Number Prey) x (Energy Cost per Prey)
what is the role of the mother?
hunt, reproduce, and raise the cubs,
what can't karyotypes tell us?
the exact parentage of each cub
Why is it better to Hunt in a group rather than solo?
You have more protection and your not gonna use as much energy in a group vs how much you would lose solo
somatic cells
any cells that do not form sperm or eggs
total energy gained
(Number of Prey) x (Energy Gain per Prey)
why do lions live in prides
it makes hunting, and caring for the cubs easier
what is the difference between a karyotype and a chromosome
chromosome shows heredity from your parents, and a karyotype detects large genetic disorders
Why are populations that are geographically closer more genetically similar?
they have more gene flow
chromosomes
heredity from parents
Net energy
(Total Energy Gain) - (Total Energy Cost)
what is the role of the male/father lion?
protect the pack, and kinda help hunt
what is a karyotype?
an individual's complete set of chromosomes, organized and displayed as a standardized visual image
which animal is defintly worth the female lions to hunt
a warthog or a wildebeast
gene flow
transfer of alleles from one population to another
what do we solve energy equations?
solving energy equations reveals whether cellular work can happen and how molecules drive life.
What are some ways variation in alleles can happen over time?
natural selection, genetic drift mutation, gene flow
How do karyotypes help determine the genetics from each parent to the children?
maps a cell's complete set of chromosomes by size, shape, and banding pattern to spot large-scale genetic and chromosomal changes
what is genetics and how does it work?
genetics is what your parents give you, like the traits you have. It works by passing biological instructions in DNA from parents to their children
resting metabolic rate
refers to the minimum number of kcal the body burns at rest.
How many human body cells do we have?
46
How do we know if an animal is worth the female lions hunting?
Use the equation. Energy Gained vs. Energy Spent
what is the most important thing to know about a karyotype
a visual map of all chromosomes in a cell, showing their number, size, and shape.
