What are inherited characteristics that enhance an organismʼs ability to survive in its environment?

Adaptations

What is a branching diagram that depicts the relationships among organisms based on shared characteristics?

cladogram

What would be the ultimate effect on an ecosystem if decomposers were eliminated?

All life would eventually cease due to a lack of available nutrients.

What type of molecule carries the hereditary information of an organism?

DNA

Which is a benefit of sexual reproduction over asexual reproduction?

The interaction of the genes from both parents allows genetic variation.

One of the conclusions drawn from Darwinʼs theory of evolution is that:

organisms living today descended from previously existing forms

Which statement best describes the cell theory?

All living organisms are composed of basic units called cells

The scientific name for coffee is Coffea arabica. More specifically, the species name is arabica.

False

With deductive reasoning, you draw conclusions from specific observations.

False

An organism that is neither prokaryotic nor photosynthetic, and must obtain its nutrients by secreting digestive enzymes into the environment, belongs to which group of organisms?

Fungi

Which scenario best describes a double-blind study?

Neither the investigator nor the subjects know who is in the experimental or control groups.

Which process is most directly associated with the theory of evolution?

Populations changing over time

You discover an organism that is eukaryotic, unicellular, and photosynthetic. Based on this evidence, to which group would you assign this organism?

Protists

During an experiment, what is the purpose of a control group?

To ensure that the results observed in the experimental group is due to the variable being tested

prokaryotes

bacteria

What is an end product of cellular respiration?

carbon dioxide

What are units of hereditary information?

genes

The human body is made up of specialized cells that perform different functions. For example, a neuron is a specialized cell of the nervous system that receives and transmits signals throughout the body. To perform these tasks, the neuron uniquely possesses branched protoplasmic protrusions, called dendrites and axons, which conduct the signals to and from its cell body. This illustrates which of the five major biological themes?

interrelation of structure and function in biological systems

Which cells do not have a nucleus or other membrane-enclosed organelles?

prokaryotic cells

soil, water, sun, and zucchini seeds

What is a subspecialty of systematics and is the science of naming and classifying organisms?

taxonomy
