Answer: Competition could limit the size of a bird population if there wasn’t enough food available. Then members of the bird population would have to compete with other populations & with each other for food to survive.
Hope this helps :)
Answer:
Plates at our planet's surface move because of the intense heat in the Earth's core that causes molten rock in the mantle layer to move. It moves in a pattern called a convection cell that forms when warm material rises, cools, and eventually sink down.
The primary function of red blood cells is to carry oxygen from the lungs to the body tissues and carbon dioxide away from the tissues and back to the lungs.
The correct answer is - Tokyo.
The most populated city in the world is the capital of the East Asia island country of Japan, Tokyo. Tokyo is a huge city, in fact, the city itself has little more than 38 million people living in it, which is more population (compared one on one) than more than half of the countries in the world.
Tokyo is the center of Japan in any sense, but only in Japan, it is a city that has enormous regional, and even global influence in every aspect, making it an extremely powerful and influential city. With the projections made about the future populations of the biggest cities, it is expected that Tokyo will be holding the first spot as the most populated city in the world until 2030, and maybe even longer.
Answer:
Evolution by natural selection
Explanation:
Most probably, the trait of being small, weak and slower did not convey advantage (or was even a disadvantage) in survival in their environment. The bigger, stronger and faster horses had an advantage and were able to survive long enough to pass down their genes to the next generation, Over succeeding generations more and more horses, therefore, became strong, bigger and faster. This is the process of natural selection at work.
