____________ Are individual things composed of several organ systems - Correct
Answers -Organisms
In the hierarchical organization of life discussed in chapter 1 groups of cells coming
together for a common function are called_________ - Correct Answers -Tissues
When a bright light hits the retina of the eye, the eye responds to the stimulus by
constructing the pupil, allowing for Less light to hit the retina. This is an example of
which of the characteristics of living things? - Correct Answers -Sensitivity
Initially a mammal consists of a single cell called a zygote. This zygote divides and
divides until it becomes a mass of cells. This mass of cells then hollows in later
separates into three germ layers of cells. As the cells continue to divide, these germ
layers create the beginnings of each organ in the body. At this stage, the zygote has
now become an embryo. The above is an example of which characteristic of living
things? - Correct Answers -Growth, development, and reproduction
Water molecules tendency to attach to other substances other than water is an example
of?
A) adhesion
B) Cohesion - Correct Answers -Adhesion
It takes a large amount of energy to turn water from a liquid to a gas this demonstrates
which property of water?
A) High specific heat
B) High heat of vaporization - Correct Answers -High heat of vaporization
The wings of a bird are used for flying and revolutionary come from the same structure
that gives rise to the forelimbs of all terrestrial vertebrates (which include dogs cats
humans etc.) Bees also have wings, but bees are insects. The evolutionary origin of
bees wings are different than that of birds wings. Based on this information which of the
following statements is true?
1) birds wings and bees wings are homologous structures
, 2) ants and dogs are more closely related than birds and dogs because they both have
legs
3) Birds wings and bees wings are analogous structures - Correct Answers -Birds wings
and bees wings are analogous structures
