- Genes are made up of DNA.
- All cells in a multicellular organism contain the same set of genes.
- Humans receive their DNA/genes from either their mother or their father but not both.
- Variations in genes are the result of mutations.
- All organisms such as roses, elephants and mushrooms have the same set of genes.
2) The circulatory system of a whale is considered an organ system because it is composed of different
- cells.
- tissues.
- organs.
- molecules.
- hearts.

4) The smallest, most basic unit of life is a(n) (Essentials of Biology, 6e Sylvia Mader, Michael Windelspecht) (Test Bank, Answer at the end of each Chapter) (For Complete File, Download link at the end of this Chapter) 1 / 4
Version 1 2
- tissue.
- organ.
- cell.
- species.
- organism.
5) Which of the following processes transforms solar energy into chemical energy?
- metabolism
- homeostasis
- respiration
- photosynthesis
- reproduction
6) As autumn approaches, white-tailed deer begin to accumulate a layer of body fat. This is an example of which characteristic of life?
- maintaining homeostasis
- metabolism
- response to the environment
- energy regulation
- organization
7) Salmon live in both fresh water and salt water during their lives. They are born in in fresh water but migrate out to marine waters for most of their life. Eventually, they return to the place they were born in fresh water to spawn. Changing between fresh water and salt water affects the balance of water in their body. Salmon have an internal control system called osmoregulation that restores the balance by negative feedback. This is an example of which characteristic of life? 2 / 4
Version 1 3
- adaptation
- reproduction and development
- response to the environment
- energy transformation
- maintaining homeostasis
8) Which of the following pairs of words is matched correctly?
- brain - organ
- neuron - tissue
- osteocyte - organelle
- gene - atom
- heart - organ system
9) Many insects cannot see the color red, and as a result many insect-pollinated flowers are colors other than red (e.g., purple and yellow). Flower color would be considered a(n)
- method for maintaining homeostasis.
- way to maintain metabolism.
- adaptation.
- example of energy flow.
- example of nutrient cycling.
10) Simon is an avid gardener who spends a lot of time caring for the plants in his garden. To minimize damage from pests from his garden, Simon uses a pesticide spray. After a few years of using the same pesticide spray, he notices that it has become less effective. This is most likely due to 3 / 4
Version 1 4
- evolution by natural selection.
- using the spray incorrectly.
- the plants in the garden evolving.
- the plants maintaining homeostasis.
- something else in the environment.
11) All the chemical reactions that occur in a cell are collectively called
- mitosis.
- photosynthesis.
- cellular respiration.
- meiosis.
- metabolism.
12) Is the following statement true or false? The only single-celled organisms are prokaryotes, such as archaeans and bacteria.
- true, because prokaryotes are the simplest cell form
- true, because all eukaryotes are multicellular
- false, because some eukaryotes, including protista, are single-celled
- false, because some prokaryotes are multicellular
- false, because all single-celled organisms are prokaryotes
13) The various species of honeycreepers have an assortment of different beak shapes, but all honeycreeper species have a similar size and body shape. This is an example of
