Biology
1 answer:
sergejj [24]3 years ago

Natural selection is a theory developed by Charles Darwin. It is believed that animal species evolve by nature "selecting" the ones that are fit to live in specific environments. For example, if an animal lacks a trait that is needed for a certain environment, it is likely to die. The animals that have the needed traits are more likely to live and procreate, which will pass on the trait to its offspring. Hope this helped!

OLEGan [10]
The answer is - because over 90% of this biome has been converted to agriculture.

This biome has been much larger before the development of the agriculture in this part of the USA, but because this biome provided large territories with deep fertile soil and predominantly lowland areas, people started using it for agriculture because it was the most suitable for that. So little by little, the biome was declining and more and more of it was becoming agricultural land.

The reason animals need a continuous supply of oxygen jis to _______________________. make carbon dioxide dispose of carbon diox
Alisiya [41]

The reason animals need a continuous supply of oxygen is to<u> Obtain energy from their food.</u>

<u></u>

The most fundamental reason why animals need a non-stop delivery of oxygen is without it animals can't achieve sufficient power from their meals.

Cells require a steady delivery of power to generate and preserve the biological order that keeps them alive. This electricity is derived from the chemical bond energy in food molecules, which thereby function as fuel for cells.

The animal's metabolism converts oxygen into strength. All through this system, a waste gas called carbon dioxide is produced. To remove it, the carbon dioxide is carried lower back to the lungs, where its miles are collected and exhaled.
