Question

A young woman sees her doctor with complaints that the bones in her left knee regularly dislocate, or move out of their usual place, painfully. Which of the following is the most likely conclusion to be drawn from this?

Her knee ligaments are weakened or injured so they can't stabilize the bones.

Her cartilage has deteriorated, providing less cushioning and causing her pain.

Her bones have become perforated and brittle due to lack of calcium in her diet.

Her knee joint's synovial fluid is not an effective lubricant between her bones.

Answer 2

im going with b

Answer 3

Yes B would be the best answer. Cartilage keeps the bones in place and if that part is detoriated, bones will dislocate easier.

Answer 4

Sounds cool

i got antother one after this one im going with
- C
An archeological student plans to compare the genomes of fossilized marine organisms from Africa and North America to identify how long ago they had a common ancestor. Like most old fossils, the tissue and shell of the organism have been replaced by quartz and calcium rock. What faulty reasoning will the student's research advisor most likely point out?

The genomes would have suffered mutations after the organisms died due to environmental factors, so they will yield incorrect ages.

The rock that makes up the fossils replaced the organisms' tissue and genetic material, so their genomes can't be extracted.

The fossils are on two different continents, so a common ancestor will not exist.

The ancient marine organisms most likely lack a common ancestor shallow enough in the ocean to be reached.
