The correct answer is - the competition will increase significantly.
If a large number of birds from the population ''a'' join the birds of the population ''b'' than the competition will increase significantly. Suddenly there will be much more competition for the food sources, for spaces for living and nesting, more competition for mating as well.
This will result in a survival of only of the fittest because the resources are limited and they only can support certain numbers of certain species. The birds that will be most efficient in finding food, be strongest, and maybe develop a certain advantageous trait will be the ones that will survive and produce offspring.
Answer:
The atomic weight of an atom is the sum of its protons and neutrons
Explanation:
The weight of an atom is dominated by the amount of matter contained in the dense and tiny nucleus of an atom. In the nucleus, protons and neutrons are found. Protons are massive nuclear particles that are positively charge. Neutrons are also massive and they carry no charges.
The atomic weight is given as the sum of the protons and neutrons. Electrons have little to no weight.

<span>The best answer is (d) water from snowmelts. The American Southwest has many mountains that catch moist air moving westward (from the Pacific) that falls as snow during the winter. The snow melts gradually during the spring and summer when there is little precipitation. The melted snow runs off the mountains into rivers and streams that can be tapped by irrigation pumps. The snowmelt also sinks into the ground, replenishing underground aquifers that can be tapped by wells in the valleys where farming takes place.</span>
Answer:
That's more than 275 million stars per day in the observable universe. Stars keep themselves fueled. They fuse elements together to make new elements. ... Once the star runs out of hydrogen, the helium atoms fuse together to make carbon.
