Traits
a specific characteristic of an organism, such as eye color or height.
What is a trait?
The biological process by which new individual organisms are produced.
What is reproduction?
The total energy of all the particles in a substance; often felt as heat.
What is thermal energy?
A strong, stretchy fiber produced by spiders.
What is Spider Silk?
The sun
What is the main source of energy for the Earth?
Through genes inherited from both parents.
How are traits passed on from parent to offspring?
Asexual reproduction involves one parent and produces identical offspring; sexual reproduction involves two parents and produces genetically unique offspring.
What is the difference between sexual and asexual reproduction?
From warmer objects to cooler ones.
How does thermal energy move?
It is used for making webs, catching prey, and creating egg sacs.
Why is spider silk important to spiders?
Solid
Liquid
Gas
What are the three states of matter?
Inherited traits come from parents (e.g., hair color), while acquired traits are learned or gained through experience (e.g., riding a bike).
What is the difference between inherited and acquired traits?
Sexual reproduction.
Which type of reproduction leads to more genetic diversity?
Conduction, convection, and radiation.
What are three ways thermal energy can be transferred?
Spider silk is stronger than steel of the same diameter.
How strong is spider silk compared to steel?
To absorb water and nutrients from the soil and anchor the plant.
What is the function of roots in a plant?
Eye color and blood type.
What are two examples of inherited traits in humans?
Bacteria
What is one organism that reproduces asexually?
Metal conducts heat away from your skin faster than wood.
What happens to the particles of a substance when it is heated?
It is lightweight, strong, and doesn’t cause allergic reactions—useful for medicine and materials.
Why are scientists interested in spider silk?
The rotation of the Earth on its axis.
What causes the day and night on the Earth?
Genes located on chromosomes in the cell's nucleus.
What controls the traits that an organism inherits?
It combines during fertilization to form a new organism with traits from both parents.
What is the role of sperm and egg cells in reproduction?
They move faster and spread apart.
What happens to the particles of a substance when it is heated?
The spinnerets.
What part of a spider’s body produces silk?
light travels faster than sound.
Why do we see lightning before we hear thunder?
