Physical differences in beaks of birds would develop as a result of different environmental changes.

<h3>What is Evolution?</h3>

This is described as the process in which heritable characteristics are changed in species over successive generations. This occurs as a result of natural selection in which the traits suitable for survival are passed to the offspring.

This is usually as a result of a change in the environmental factors which ensures that the organisms are able to adapt so as not to die out and go extinct in this type of scenario.

Check all statements below that are true
victus00 [196]

Answer:

Statements thar are true:

Some  organisms have phenotypes that make them better  increase chances of reproduction.

Natural selection continues to occur even today

Phenotypes found In the most successful members of a species become the most prevalent after  several generations.

Explanation:

It is not true that all organisms must compete for survival, sometimes the conditions are good and there is enough food or good climate conditions and that makes no need of competition an increase in the individuals of the species.

Animals undergo natural selection, this is a random natural phenomenon that can make plants and animals adapt better or worse to the enviromental conditions. This cause that the beneficiaries can adapt, survive and reproduce and became the most prevalent after generations.

Mutations are not phenomen that occur because the living being needs it, but rather they are phenomenon that occur at random at any time and determine the possibility of survival.

A decrease in food availability will do the contrary, decrease the variation in a population because it makes that only those who manage to adapt to eat another food survive, for example.

Since this theoretical organism called a "superfly" does not die and has unlimited resources, the type of population growth for this particular species will be exponential. In plotting the graph of exponential growth, a J-shaped curve will be the result, starting from a steady logarithmic increase then eventually being vertical.
