Meaning of invertebrate and vertebrate​

Answer:

Vertebrate:spine Invertebrate:no spine

Explanation:

Answer:

Invertebrates are animals that do not have backbones. 95%-97% of the members of the animal kingdom are invertebrates such as sponges, jellyfishes, squids, and roundworms.

Vertebrates, on the other hand, are animals with a backbone or a vertebral column and are composed of six groups: mammals, birds, reptiles, amphibians, and fishes. Humans are members of the vertebrates family too but are sometimes exempted from the list when the discussion leans towards animals.

You have learned that heat moves from warm areas to cooler ones. In solids, heat is transferred by the physical touching of molecules. This type of heat transfer is called conduction. Some materials, like metal, conduct heat better than other materials. In fluids (liquids and gases), heat is transferred by convection currents caused by differences in density.

MATERIALS
hot water
cold water
metal fork
plastic fork
stick of cold butter
large glass
watch or clock with a second hand
yellow and blue food coloring
playing card
four empty, identical plastic bottles (sports drink bottles work well)
access to a sink

QUESTIONS
Part 1
What type of heat transfer is demonstrated in Part 1?
How long did it take for the butter to melt off of the plastic fork? The metal fork?
How do explain the difference in time between the two forks?
Part 2
What type of heat transfer is demonstrated in Part 2?

Juanita and Alfred hypothesize that a seed will sprout faster if it is warmer. They plant three seeds and water them the same amount. One seed is placed near a heater, one is left at room temperature, and one in a refrigerator. The results are shown in the table below. Do the results support the hypothesis?

Temperature of Seed Days to Sprout
by heater 2 days
room temperature 5 days
in refrigerator did not sprout
A.
No, because the seeds all sprouted at the same time.
B.
Yes, because the cooler seeds sprouted sooner.
C.
Yes, because the warmer seeds sprouted sooner.
D.
No, because the cooler seeds sprouted sooner.
