Answer:
Random chance mutations led to the webbed feet trait in ancestral land birds, conferring them an adaptive advantage. Birds that inherited the beneficial random mutations associated with the webbed feet trait had more chances to survive and reproduce, passing this trait to the next generations.
Explanation:
Mutations are ramdom changes in the nucleotide sequence of the genome of a particular organism. In general, mutations are deleterious, but mutations may occasionally be beneficial in certain environments. A beneficial mutation must be associated with one or more phenotypic traits capable of conferring an adaptive advantage in a certain environment, thereby the individuals carrying the mutation have more chances to reproduce and survive. In this case, one or more beneficial mutations associated with the webbed feet trait passed to the next generations, increasing their frequency in the population.
Answer:
False I think not too sure
Explanation:
Neurons have three parts that carry out the functions of communication and integration : dendrites , axons , and axon terminals .
If they both have Rr. The possibilities will be RR, Rr, Rr, rr. They have a 25% chance of inheriting the recessive trait instead of their dominant trait. That means that these traits are hidden and not expressed in the previous generation.
Answer:
agriculture leads to more oxygen production and more carbon consumption.
