1- The equation below represents a summary of a biological process.
carbon dioxide + water changes to glucose + water + oxygen
This process is completed in
(1) mitochondria (3) cell membranes
(2) ribosomes (4) chloroplasts
2 The flow of energy through an ecosystem involves many energy transfers. The diagram below summarizes the transfer of energy that
eventually powers muscle activity.
un changes to Food changes to ATP changes to Muscle Activity
A B C
The process of cellular respiration is represented by
(1) arrow A, only (3) arrow C, only
(2) arrow B, only (4) arrows A, B, and C
3In an ecosystem, which component is not recycled?
(1) water (3) oxygen
(2) energy (4) carbon
1 A student observes that an organism is green. A valid conclusion that can be drawn from this observation is that
(1) the organism must be a plant
(2) the organism cannot be single celled
(3) the organism must be an animal
(4) not enough information is given to determine whether the organism is a plant or an animal
4 Studies of fat cells and thyroid cells show that fat cells have fewer mitochondria than thyroid cells. A biologist would most likely infer that fat tissue
(1) does not require energy
(2) has energy requirements equal to those of thyroid tissue
(3) requires less energy than thyroid tissue
(4) requires more energy than thyroid tissue
5 Living organisms must be able to obtain materials,change the materials into new forms, remove poisons, and move needed material from one place to another. Many of these activities directly require
(1) energy released from ATP
(2) carbohydrates formed from receptor molecules
(3) the synthesis of DNA
(4) the breakdown of energy-rich inorganic molecules
6 Which process is directly used by autotrophs to store energy in glucose?
(1) diffusion (3) respiration
(2) photosynthesis (4) active transport
7 Fruit flies with the curly-wing trait will develop straight wings if kept at a temperature of 16°C during development and curly wings if kept at 25°C. The best explanation for this change in the shape of wings is that the
(1) genes for curly wings and genes for straight
wings are found on different chromosomes
(2) type of genes present in the fruit fly is
dependent on environmental temperature
(3) environment affects the expression of the
genes for this trait
(4) higher temperature produces a gene mutation
8 Some mammals have genes for fur color that produce pigment only when the outside temperature is above a certain level. This pigment production is an example of how the environment of an organism can
(1) destroy certain genes
(2) cause new mutations to occur
(3) stop the process of evolution
(4) influence the expression of certain genes
