Bony Fish (bass etc.) and marine mammals (like dolphins) evolved some similar adaptations for survival in aquatic environments.
xeze [42]

Answer:

Convergent evolution

Explanation:

Convergent evolution is a type of evolution of similar features and/or structures between organisms that are not phylogenetically related. This type of evolution is known to create analogous structures/organs that exhibit similar or the same functions but were not present in the last common ancestor of these taxa. An example of analogous structures (and therefore also of convergent evolution) are the wings of bats and of insects (e.g., butterflies). Conversely, divergent evolution is a type of evolution where species phylogenetically related, i.e., species that share a common ancestor, evolve and accumulate differences over time.

After completing 10 years of experimentation, a scientist reports a new scientific law about the movement of sand on beaches. Ho
Setler [38]
Experimentation (or the experiments the scientist was doing for 10 years) could be wrong or done in an inappropriate way. The only way to know if the information is valid is by checking the way the experimentation (data) was done as well as making sure to check all other factors

Newton's second law can be demonstrated by which of the following
shutvik [7]

Newton's second law can be demonstrated by something very massive (high mass) that’s changing speed very slowly (low acceleration) and something very small (low mass) that’s changing speed very quickly (high acceleration. Thus, both the options A and B are correct.

<h3>What is Newton's second law?</h3>

According to newton second law of motion force is always equal to rate change of momentum.

So, Force basically depend on two factor i.e mass and velocity

In first case if mass is constant and velocity is variable then

Force = mass × acceleration.

And if mass is variable and velocity is constant then it's called thrust force

Thrust force = Rate change of mass × velocity.

S.I unit of mass is Newton.

Therefore, Newton's second law can be demonstrated by something very massive (high mass) that’s changing speed very slowly (low acceleration) and something very small (low mass) that’s changing speed very quickly (high acceleration. Thus, both the options A and B are correct.
