mmon ancestor, the wolf, Canis lupus. Many breeds, such as the Alaskan malamute and the Siberian husky look remarkably like wolves and even retain some of their habits. Other breeds like the daschund above, do not strongly resemble wolves.
What part of the theory of evolution by natural selection would explain why there are no wild wolves that resemble dachshunds?


A) Natural selection leads to evolution.
B) There is very little genetic variation in all living species.

D) Competition favors the fittest organisms. 
This is correct because, in different parts of the world, different organisms need different things to survive, which means if Wolves in Alaska need warm coats to survive, but animals in some parts of America don't, each animal that is the fittest to live in those conditions will survive, while the others with unfavorable genes will not.

Which is an example of positive gravitropism?
AveGali [126]

Answer:

c. the plant root growing down into the soil

Explanation:

The plant root going down deep into the soil is an example of positive gravitropism. Gravity pulls everything towards the center of earth i.e. downwards and roots follow the direction of gravity automatically by growing downward towards soil that is why it is known as positive gravitropism. In short we can say that root favors the direction of gravity.

Shoot on the other hand show negative geotropism/gravitropism i.e. it grows towards the opposite direction of gravity. Shoot grow towards upside direction i.e. away from the surface towards sky.
