Compared to all other members of the animal kingdom an adult female human being is slightly smaller than the average animal in size and weight.

True

False

 

Cells are generally quite small as a result of limitations imposed by surface-to-volume ratios.

True

False

 

Bacterial cells are different from the cells of plants and animals in that they have much smaller nuclei.

True

False

 

In a complex, multicellular organism like a human being each distinct kind of cell (e.g. muscle cell, skin cell, nerve cell) will have its own unique set of genes.

True

False

 

Plants create energy in the chloroplasts of their leaves.

True

False

 

Because animals lack chloroplasts they cannot produce energy.

True

False

 

Within chloroplasts the "light reactions" take place only during the day while the "dark reactions" take place only at night.

True

False

 

Although animals have only mitochondria, plants have both mitochondria and chloroplasts.

True

False

 

Although animals have mitochondria to handle many key energy transformations, plants must rely on chloroplasts for all their energy manipulations.

True

False

 

Plants are able to assemble certain food molecules from water and simple molecules in the air.

True

False

 

When biologists refer to the idea of evolution through natural selection as a "theory" they imply there are serious remaining doubts about it.

True

False

 

A wide variety of new adaptations were initiated in plants and animals because they were needed to survive.

True

False

 

In any group of animals it will always be the biggest and strongest that survive.

True

False

 

Traits that an animal species has lost through evolution (e.g. the legs of snakes) disappear because the animals no longer need them.

True

False

 

When both the dominant and recessive form of a gene are both present in an individual it will usually be the dominant trait that appears.

True

False

 

The dominant form of a gene inevitably becomes more common than the recessive form of the same gene.

True

False

 

The basic structure and function of DNA is very similar in all kingdoms of life: bacteria, fungi, protists, plants and animals.

True

False

 

Although the structure of DNA may be similar in all kingdoms, how information is encoded in DNA is quite different in different groups.

True

False

 

The only reliable source of information in a biology class is the instructor.

True

False

 

Biologists rely exclusively on experimentation and the scientific method to increase understanding of living things.

True

False
