One of the tail feathers of the male barn swallow is longer than that of the female barn swallow. The long tail feather helps the males attract females, but it also
requires the males to use extra energy to fly. The long tail feather trait stays in
the barn swallow populations because, compared to males with a shorter tail
feather, males with a longerltail feather are more likely to:
a. build a large nest.
b. produce offspring (reproduce).
c. migrate each winter.
d. escape from predators.

Plz ! a frog has a genetic mutation in skin cells that causes part of its skin to turn orange the frog will not pass this genetic mutation onto its offspring because, a. the offspring will inherit skin cells from the other parent. b. mutated skin cells cannot divide and produce daughter skin cells. c. skin cells do not contribute genetic material to sex cells. d. parents do not contribute genetic material to their offspring.

To maintain asepsis when administering an injection, all parts of the syringe can be handled except the:

Subduction zones form when an oceanic plate collides with another oceanic plate or continental plate. the continental crust is lighter and less dense than oceanic crust. continental crust's density is approximately 2.7 grams per cubic centimeter. oceanic crust is thinner and the average density is about 3.3 cubic centimeters. when the two crustal plates converge the oceanic plate always bends and subducts beneath a continental plate. once the oceanic crust subjects, the rocks are subjected to changes in heat and pressure. because of this, we would expect to find rocks in the area of a subduction. a) clastic b) igneous c) metamorphic d) sedimentary
