considering the thick brown fur of the back of the bear image, which of the following explains how this is a favorable trait for a bear living in Canada?
the brown hair helps it blend into the green grass
the brown hair look fierce and scares off predators
the brown hair is thick and provides warmth
the brown hair is water repellent
the brown hair limits the damage done by lightning strikes
considering the front half of the bear, with the snowy environment behind it, which of the following does not fit as a trait that increases its survival?
sharp claws to attack prey with
water storing structures to survive dry periods
white fur to blend in with the snowy environment
blubber to stay warm in the snowy environment
these beetles exist in west Texas, where males in the species will fight each other for the right to mate with females. males with larger jaws tend to win these fights. which of the charts below best displays the trend we would see over many generations as a result?
the adaptation of large strong jaws appears/ evolves from smaller jaws because this trait leads to...
cooler looking beetles that reproduce more than smaller jawed beetles
tougher beetles that reproduce less than the smaller jawed beetles
beetles that out-compete smaller jawed beetles, and reproduce more
beetles with big jaws because the female beetles want their offspring to have bigger jaws
The graph above show the composition of the claw size in a population of sloths living in a forest. The size of claws only has two variations: 3 inch claws and 5 inch claws. Which of the following statements accurately describes trends seen in the graph?
Over time the percentage of the population with 3 inch claws increases while the percentage of the population with 5 inch claws decreases
Over time the percentage of the population with 5 inch claws increases while the percentage of the population with 3 inch claws decreases
Over time the percentage of the population with both claw types increased
Over time both of the variations of claw size held their same percentage of the populations
Which two of the following statements are a possible explanation for the shift in the percentage of both claw size variations?
after generation 60 animals with the two different claw lengths were separated and didn’t mate with each other any more
after generation 10 the sloths stopped using nail clippers, this helped them survive more
after generation 10 there was a change to the environment that made having larger claws help them survive more
when the data was first being collected 3 inch claws were a favorable trait
Sloths live for an average of 20 years. Based on that figure, the graph above, and our discussions of evolution and adaptations, would you say that the acquiring of adaptations is a fast or slow process?
Fast
Slow
Litter is the term used to describe the multiple offspring born at one time, we often see this word used to describe puppies or kittens.
based on the graph we can see that over time the litter size is (increasing or decreasing)
(a)
this is a multiselect question. please select 3 correct choices for your answer
sweet smell
spreading through the wind
nectar/ honey/ some type of food source
foul/ bad odor
bright colors
variation means
similarities
differences
adaptations are
traits that an animal or plant acquires during their lifetime then passes down to their offspring
traits, based on variations in the population, that help an organism survive. They become more common in the population over time
examples of adaptations include (select three)
a prosthetic leg for amputee
xylem in plants for transporting water and nutrients
being nocturnal in a hot environment
producing insulin to regulate blood sugar levels
eye glasses to correct vision
xylem is an internal structure found in many plants, xylem is a favorable trait because it is a tube within the plant that transports water/ nutrients around the plant. which body system does this remind you of? (delivering nutrients around the body like a highway)
endocrine
circulatory
respiratory
muscular
digestive
of the following, which types of plants would benefit most from having xylem (a tube inside of the plant that delivers water and nutrients from the ground around the plant) as one of its adaptations?
small plants that grow close to the ground's surface- like grass
tall trees whose leaves and branches may be 60 feet off the ground
colorful flowers because their pigment that makes them that color requires extra nutrients
plants that bloom in the spring then go dormant in late fall
adaptations happen more easily in ___________ reproduction because ______________
asexual; the offspring are clones of their parents
asexual; the increased genetic diversity allows for adaptations
sexual; the offspring are clones of their parents
sexual; the increased genetic diversity allows for adaptations
