7th grade mid-term study guide quiz #2

Answers are highlighted in red.

1. Mokey the Fraggle is working with a team of scientists to study the rock formations at the
Red River Gorge. She stops at a big, rocky arch and writes:

The rocks on this arch are brown and gray in color. They feel crumbly and soft.”
Is this statement an OBSERVATION or an INFERENCE?

2. Mokey continues to hike through the gorge and sees two sets of footprints on the trail ahead of her. She says:

I am guessing a duck and a raccoon made friends, since their footprints are side by side!
Is this statement an OBSERVATION or an INFERENCE?

3. In Fraggles, there is a single gene that controls skin color.
The dominant phenotype is blueish/purple skin, and the recessive phenotype is
orange skin. Bubber is heterozygous for this trait. Red is homozygous recessive.
GIVE Bubber and Red’s GENOTYPES.
Use the letter “K” or “k” to represent the skin color gene.

BUBBER - Kk

RED- kk

4. Do a punnett square crossing Bubber, whose genotype for skin color is Kk, and Mokey,
who’s genotype for skin color is kk.

5. If Mokey and Bubber were to mate and have 4 fraggle babies, make an educated guess as to how many of them would show the recessive trait for skin color (orange skin). This is the one question you should answer in complete sentences! Use data from your answer to question #4 to support your answer to this question.
If Mokey and Gobo were to mate and have 4 fraggle babies, 50% of their fraggle babies would be orange skinned, because all of the possible outcomes, 2 of the 4 have the dominant gene for skin color.

Cardi is taking data on honey bees and whether or not they have a preference of flower type. She writes 4 statements in her science notebook. CLASSIFY each statement as an observation OR an inference: I saw 5 bees go to the pink flowers and 15 bees visit the blue flowers. OBSERVATION I noticed the blue flowers smell sweet and fruity, while the pink flowers do not smell at all. OBSERVATION I think the blue flowers have sweeter nectar, and that is why the bees prefer them. INFERENCE I also counted 2 butterflies on the blue flowers, and 0 butterflies on the pink flowers. OBSERVATION

EXTRA CREDIT week of 11.6.2018

Write 5 facts about things you learned from listening to this audio clip.
Your facts should be:
1. In complete sentences
2. Complex in nature 
For example, I already know the 7th grade studied DNA transcription. If a students turns in an extra credit assignment, and one of their facts is: DNA is transcribed in the nucleus, that isn't a complex fact! We learned that a few weeks ago. If a student writes Bacteria cells do not have a nucleus, so transcription and translation happen in the cytoplasm, unlike in animal cells, THAT is a complex, new idea, and THAT is worth extra credit!
