Title- m& m lab
purpose
to learn more about phenotype and genotypes
the probability of the size of fish
how to calculate phenotype and genotype
iii. materials
m& ms
brown paper bag
iv. procedure
every m& m we get we tally which color it is
if it’s 2 light ones we get to eat them (one for each person in your group)
if it is any other m& m like ll or ll we don’t get to eat them
after we are done with the calculations we are to put them on our lab questions
v. results
starting population | allele frequencies- long- 25 short- 25

vi. conclusions
if we had more m& ms we would have had better answers than only having 50 m& ms

this is my lab report i'm working on and i need the type of natural selection and a detailed disciption of which natural selection it is can anyone me witht this
the types are
-sexual
-disruptive
-directional

Hunting in the darksome fish rely on senses beyond sight. in the darkness of the marianas trench, a fish called the rattail has an extremely sensitive sense of smell. the fish uses scent, rather than sight, to steer toward food. once it's near food, the rattail uses a special organ on the bottom of its chin to guide itself by feel.marine snowone staple of the deep sea diet is "marine snow," flakes of organic, edible substances that sink down from the upper ocean. animals at the ocean's bottom find sustenance in everything from the bodies of dead creatures to fecal matter. marine snow is diverse enough to support numerous species. for instance, several species of snails and worms feed exclusively on deceased whales.microorganismsthe deep sea is an intricate ecosystem, and even the ocean floor itself plays a part. hydrothermal vents are cracks in the sea floor where erupting magma mixes with ocean water to produce plumes of hot, sulfur-rich chemicals. some microbes can use these chemicals for energy, sustaining their existence and that of the animals who depend on their roles in the deep sea food chain.

Other organisms can change their behavior to take the place of the plants in the ecosystem.
