3. A geology student describes a rock sample she is studying in class. The rock sample is igneous rock, but the student wonders if the material that it formed
from was part of a sedimentary rock formation millions of years ago. Could this
be correct? Could the material for igneous rock come from sedimentary rock?
a Yes, if sedimentary rock is exposed to energy from the sun at Earth’s surface
for a long enough time, it can melt into liquid rock and form igneous rock.
b Yes, if sedimentary rock is moved below Earth’s outer layer and exposed to
energy from Earth’s interior, it can melt into liquid rock and form igneous rock.
c No, igneous rock can only form from other igneous rock. Sedimentary rock
cannot change into igneous rock.
d No, igneous rock forms under Earth’s outer layer due to energy from
Earth’s interior, but sedimentary rock only forms at Earth’s surface.

How does oxygen move from the respiratory system to the circulatory system? a. by pumping through the heart b. by circulating in an artery c. by moving across a synapse d. by diffusion across a capillary wall

In a hypothetical breed of dogs, coat color is controlled by two genes. there are six different coat colors in this breed: black, brown, cream, gray, silver, and tan. consider the following crosses. cross 1: black females from a lineage of all black dogs are crossed with brown males from a lineage of all brown dogs. f1 males and females are all black. when f1 are intercrossed, f2 males and females are black or brown. cross 2: black females from a lineage of all black dogs are crossed with tan males from a lineage where all males are tan and all females are cream. f1 males are black, f1 females are gray. when f1 are intercrossed, f2 males and females are black, brown, gray, or tan. cross 3: silver females from a lineage where all females are silver and all males are gray are crossed with brown males from a lineage of all brown dogs. f1 males and females are all gray. when f1 are intercrossed, f2 males are black, brown, gray, or tan, f2 females are cream, gray, silver, or tan. select the correct statements regarding the mode of inheritance of the coat color genes. a) both genes are x-linked. b) both genes are autosomal. c) one of the genes modifies the expression of the other gene. d) each gene has an additive effect on the intensity of coat color. e) each gene independently specifies three colors. f) one of the genes is autosomal, and the other is x-linked.

Connection compare and contrast genetic engineering to the process of natural selection. select all statements that are true.
