Answer:
Primitive Earth where life emerged was subjected to extreme conditions
Explanation:
The origin of life is still an issue of intense debate today, although most researchers believe that life emerged from primitive organisms generated by the synthesis of organic compounds in early Earth. In line with this theory, it has been shown that membrane-forming compounds can be formed in extreme conditions (i.e., UV rays, extreme temperature, etc). It is believed that such conditions recreated in a laboratory were similar to the early Earth about 3,900 million years ago, thereby supporting the idea of the 'primordial soup theory' proposed by John Burdon Sanderson Haldane in 1929.
A, because because because because because yes❤️
Hey there!
I'm assuming it's pointing to the wall in between the two sections of the heart.
We can go over the function of the blue section and red section of the heart. Though I must admit I am not well versed with hearts of birds, I will assume this is similar to a human one. The blue section <u>receives blood from the body which doesn't have any oxygen left in it,</u> and the red section <u>receives blood from the lungs, newly oxygenated.</u> This sector in between separates these two sections, and separates oxygen-poor blood and oxygen-rich blood.
Thus, your answer is option D.
Hope this helps, feel free to let me know if you have any additional questions about this specific problem!
