Biology EOC Review #4

Which of these is required for natural selection?

• All individuals of a population must be identical.
• There must be a small number of individuals in a population.
• There must be variation among the members of
• An individual must be forced out of its natural habitat.

The chart shows the embryos and adult forms of animals from different classification groups.  What do the embryos suggest about these three animals?

• The animals are not related.
• The animals share a common ancestor and are therefore related
• Fish are more closely related to humans than are chickens.
• Fish and chickens ar closely related, but humans are not related to either fish or chickens.

Fossils show that cyanobacteria evolved at least 3.5 billion years ago.  How did cyanobacteria change Earth's environment?

• They made it hotter.
• They added oxygen to the atmosphere.
• They added nitrogen to the soil.
• They added carbon dioxide to the atmosphere.

The genetic variation that leads to evolution can occur when genes from one population are introduced into the gene pool of a different population.  This process is known as

• mutation
• crossing over
• natural selection
• gene flow

Which of these processes is most likely to increase the genetic diversity that plays a role in evolution?

• binary fission
• cell division
• asexual reproduction
• sexual reproduction

With what 3 letters do enzyme names typically end?

• -ose

• -ase

• -ese

• -tic

Which list includes only structures that would be found in a prokaryotic cell? 

• Cell wall, plasma membrane, mitochondria
• Central vacuole, cell wall, lysosome
• Cell wall, plasma membrane, cytoplasm
• Plasma membrane, nucleus, mitochondria

What is the function of this molecule in organisms? 

• Storage of genetic information
• Structure and support
• Short term energy storage
• Long term energy storage

Which best describes the function of enzymes?

• to speed up chemical reactions in a cell
• to produce cellular energy
• to produce proteins
• to speed up cell division

What are the products of photosynthesis? 

• glucose and oxygen
• glucose and carbon dioxide
• glucose and water
• water, carbon dioxide, and energy
