The structures are evidence of evolution in that all living things are homologous with a genetic code which is extremely similar though other genetic code exists and then it suggests a common ancestor.
Human harm is considered homologous structures together with bird’s wings, cat’s legs. A human being has bones for example ulna, fingers, and wrist bones that features appear similar to ones in other animals. Bat’s whales have similar homologous structures which demonstrate that these creatures have a common ancestor.
Answer:
Explanation:
Density is equal to mass over volume.
The mass of the wood is 6.0 grams and the volume is 12.0 cubic centimeters.
Substitute the values into the formula.
Divide.
The density of the wood is 0.5 grams per cubic centimeter.
If vector is less than 90° and greater than 0°, it’s positive. if it’s less than 180 and greater than 90, it’s negative. if there is no acceleration vector, it’s called zero acceleration.
Answer: B) The opposing force of friction stopped the train.
Explanation:
From Newton's first law of motion, we know that an object remains in the state of rest or constant motion unless and until acted upon by an unbalanced net force.
Here, the rolls to a stop along a horizontal track without application of break. There is absence of an applied force. It means that a force of friction acting in the opposite direction of motion train eventually brought it to rest state. Hence, the correct option is B.
