The diagram shows a chicken embryo and a human embryo. Which is best supported by the diagram?

Because their embryos have tails, chickens and humans do not likely share a common ancestor with fish.
Because their embryos have structures similar to gills, chickens and humans likely share a common ancestor with fish.
Chickens and humans have homologous structures as embryos, so they are not likely related to each other.
Chickens and humans have homologous structures as embryos, so they are not likely related to any other organisms.

Abucket full of water weights 4 kg and water well is 10m deep. a girl draws water from the well. it takes the girl 3 minutes to draw a bucket full of water from the well. what is the power of the girl?

Boxing gloves are padded to lessen the force of a blow. (a) calculate the force exerted by a boxing glove on an opponent’s face, if the glove and face compress 7.50 cm during a blow in which the 7.00-kg arm and glove are brought to rest from an initial speed of 10.0 m/s. (b) calculate the force exerted by an identical blow in the gory old days when no gloves were used and the knuckles and face would compress only 2.00 cm. (c) discuss the magnitude of the force with glove on. does it seem high enough to cause damage even though it is lower than the force with no glove?

Suppose you increase your walking speed from 7 m/s to 13 m/s in a period of 2 s. what is your acceleration?
