Why have antibiotics become less effective against harmful tuberculosis bacteria over time? 

• We have have adapted to the presence of bacteria, causing antibiotics to be less effective.
• Any bacteria with mutations protecting them from the antibiotics were more likely to live and pass on the mutations.
• The bacteria has learned to avoid the antibiotics within the human body.
• The anibiotics have become weaker over time

Which of the following terms is referred to as the transfer of alleles or genes from one population to another?

What three things are trends that scientists have seen in hominid evolution? 

• Smaller brain size, increasing jaw size, and broad forhead
• Increasing body size, thick skulls, and large brow bone.
• Decreasing brain size, large canines, and thick skulls.
• Bipedalism, increasing brain size, and use of tools.

How can a bacteria recognize the human gene and produce a human protein? 

• The basic components of DNA are the same in humans and bacteria.
• Bacteria cells and human cells reproduce through sexual reproduction.
• Bacterial cells have the same organelles as human cells.
