A snake has scaly skin to keep from drying out in the desert. A cactus has sharp spines and a think stem that keep water in. What term describes such inherited traits that help organisms survive?
Adaptions

Gene
Crying is a behavior that is similar to a spider spinning a web. Both come naturally. They do not have to be taught. What are these behaviors called?
Instincts

A flower in the shade not growing very tall
Salamanders, Fish, Ghirial, Sloths, Spiders, Cicadas, Frogs, Salamanders, Cheetahs, Humans, Ladybugs,

What did scientist Gregor Mendel discover during the 1800s?
Some inherited traits are dominant and others are recessive.
Describe the inherited traits of a tree.
Flower color and height
Some organisms go through a metamorphosis as they grow into adults. In some cases, the metamorphosis is called complete metamorphosis. In other cases, the process is called incomplete metamorphosis. Describe the steps in incomplete metamorphosis.
Egg, Nymph, Adult
Organisms live, or perform basic functions to stay alive. They also survive, or compete for resources, protect themselves, and find food. What is an example of a fly using a structure of it's body to escape from predators?
Flying
What do spiders and horses have in common when it comes to their life cycles?
Both begin life as a single cell.
Important discoveries in the history of science help students learn scientific concepts today. What did the work of Mendel in the 1800s help people understand?
How traits are inherited
Give an example of an animal with an inherited behavioral trait.
Human babies crying, fish swimming, chickens pecking for food, birds building nests.
In the metamorphosis of a ladybug, which step comes just before the adult stage?
Pupa
Why are so many bacteria now able to resist antibiotics?
A few bacteria resisted antibiotics, survived, and multiplied.
All animals start out as a single cell. In a model that shows how a cell divides, what patter shows the resulting number of cells for the first four steps?
1, 2, 4, 8
A litter of rabbits is born in an area with lots of snow all year. Two babies are white and two are brown. What does this tell you about the rabbits variation?
The variation will help the white rabbit survive.
Give an example of an instinct passed down from parents to offspring in relation to chickens.
Why would a butterfly lay an egg on a leaf, based on what you know about compete metamorphosis?
The egg hatches into a larva, which eats leaves, so it can eat right away.
What is a structure that is a physical adaption that helps penguins live in icy, wet environments?
Webbed feet for swimming
A student is studying for a test on animal life cycles. What animal could the student look at as going through metamorphosis during its life cycle?
Ducks
Animals inherit certain characteristics, such as fur color. What are some characteristics that plants inherit?
Flower color
Tell the difference between an instinct, learned behavior, physical adaption, and inherited traits
Does not have to be taught
Behaviors that are taught
Physical characteristics that help organisms survive
Traits that do not help an organism survive (eye color)
How many steps are in complete metamorphosis? What are they?
Egg, larva, pupa, adult
