Alexis is studying how lenses work. She looks through a magnifying glass and through the peephole of a door.
Which best describes a difference between the lenses
used in these two devices?
O The lens in the magnifying glass can produce both
real and virtual images, but the lens in the peephole
can produce only real images.
O The lens in the magnifying glass can produce only
real images, but the lens in the peephole can produce
both real and virtual images.
O The lens in the magnifying glass can produce both
upright and inverted images, but the lens in the
peephole can produce only upright images.
O The lens in the magnifying glass can produce only
inverted images, but the lens in the peephole can
produce inverted and upright images.

In the nineteenth century, gregor mendel first determined some basic rules of genetics that have been observed throughout all types of life. no observations have disproved these basic rules of genetics. charles darwin developed the idea of biological evolution around the same time, but he was unaware of mendel’s discoveries in genetics. over a century later, darwin’s idea of evolution was modified in order to incorporate mendel’s rules of genetics along with the other evidence that darwin had used. what is most likely the relationship between mendel’s rules of genetics and darwin’s idea of biological evolution? a.)mendel’s genetics states laws that are now part of the theory of biological evolution.b.)biological evolution states laws that are part of mendel’s theory of genetics.c.)mendel’s genetics replaced darwin’s entire concept of biological evolution.d.)biological evolution is a law that explains why all genetics exist.
