Angela set out to determine how many genes control the length of people's eyelashes. She
compared the length of eyelashes from 12 different
people. She measured each person's eyelash by
placing the eyelash on a metric ruler and measuring
the length directly.
What is a possible source of error in her
experiment?
A. She did not collect data from enough
people.
O B. She should have considered the number of
eyelashes on each eyelid in her data
collection.
O C. She may have had a difficult time making
accurate measurements directly.
O D. She did not include a control group.

Which survival need shortage would most affect articular cartilage's ability to rebound after joint compression, and why does it have this effect? which survival need shortage would most affect articular cartilage's ability to rebound after joint compression, and why does it have this effect? nutrients, since the majority of cartilage is made out of polysaccharide glycosaminoglycans (gags). water, since it makes up to 80% of cartilage's content and cushion articular bone surfaces. normal body temperature, since higher temperatures would slow down necessary biochemical reactions. oxygen, since cartilage cells receive this gas directly from nearby blood vessels?
