Scientist were investigating a pond of water found deep in a south American cave along the Yucatán peninsula. They obtained many samples which they took back to their lab. After much testing, they found that the water has an acidic pH of three. Another much more surprising discovery was that a new species of unicellular organisms was present in the samples. The organism was observed with the microscope and found to not have a bounded nucleus or organelles. To which domain would this organism be classified?
A. Archaea
B. Protista
C. Bacteria
D. Eukarya
A. Archaea

In the human body, organ-systems interact with each other to maintain homeostasis.
(Refer to graph #4)
Using the diagram above, select the answer that BEST explains how this system interacts with another.
A. The immune and digestive systems work together to provide protection against infectious organisms in the body.
B. The digestive and excretory systems interact to produce and remove waste from the body.
C. The respiratory and digestive systems work together to produce and transport nutrients to all cells in the body.
D.The circulatory and digestive systems interact to produce and deliver oxygen to the body.
B. The digestive and excretory systems interact to produce and remove waste from the body.
4. In the 1700s, Carl Linnaeus designed a system for classification of organisms into2 Kingdoms called Plantae and Animalia. It was not until the 1960s that Thomas Whittakersuggested a 5 kingdom classification system that also included Monera, Protista and Fungi.Carl Woese later proposed a reorganization of the five kingdoms into three domains, Eukarya, Eubacteria and Archaea. When Charles Darwin published his findings on evolution, biologists began to use cladograms to classify organisms based on evolutionary ancestry. (Refer to graph # ) Now, DNA can even be used to group organisms.
How was the system of classifying organisms able to change after so many years of using the original Linnaeus system of the kingdoms, Plantae and Animalia?
A. The system of classification changed when more a more famous scientist presented a method.
B. The system of classification changed as new credible scientific discoveries were made
C. The system of classification changed when Carl Linnaeus was proven wrong.
D. The system of classification changed based on the most current method.
C. The system of classification changed when Carl Linnaeus was proven wrong.
The pedigree below shows two generations of individuals within a family. The pedigree shows that a daughter has a genetic condition, that neither her parents nor siblings have.
(Refer to graph #)
What is the best explanation for the daughter having this genetic condition?
A. The condition is one that is not inherited.
B. The daughter's genes carry dominant and recessive alleles inherited by the parents.
C. One parent must have genes that carry a dominant allele for the condition.
D. Both parents' chromosomes contain genes that carry the recessive trait.
B. The daughter's genes carry dominant and recessive alleles inherited by the parents
Male cricket chirp to attract a mate. Chirping is dangerous because it can also attract predators such as birds or bats. Sometimes, other male crickets will wait quietly near and intercept the female on her way to a chirping male.

Every cell in our body needs oxygen and nutrients to produce energy. When we inhale, oxygen is taken into and transported to various parts of the body. Cells use oxygen to break down the nutrients from food to release energy. During this process waste products are produced. Which statement BEST describes the organ system is working together during this process?
A.The immune system take in and provides oxygen to the respiratory system, which then delivers the oxygen to the excretory system where it is used to break down food for energy.
B. The musculoskeletal system takes in and provides oxygen to the circulatory system, which then delivers the oxygen to the reproductive system that uses it to break down food for energy.
C. The respiratory system take in and provide oxygen to the circulatory system, which then delivers the oxygen to cells that use it to break down energy for food.
D. The reproductive system takes in and provides oxygen to the nervous system, which then delivers the oxygen to the digestive system that uses it to break down food for energy.
C. The respiratory system take in and provides oxygen to the circulatory system, which then delivers the oxygen to cells that use it to break down food for energy.
