Answer:
That would be A. Covalent bond!
Explanation:
Since the bond formed is an ester bond, these bonds are covalent in nature and so the answer is A.!
Bapak teori organik ialah Dr Henry Chang menyatakan makanan organik adalah produk pertanian yang bebas dari sebarang bahan kimia.Organic bermaksud "berasal dari tanah" dan memiliki kandungan gizi yang lebih baik.Makanan organik diperbuat mengikut piawaian pengeluaran tertentu, iaitu ditanam tanpa penggunaan racun perosak dan baja buatan manusia, bebas dari pencemaran akibat sisa manusia atau industri,

experienced during sleep apnea can last for a few seconds to a few minutes
and it usually happen many times in the night. Thus, sleep apnea disrupts
normal sleep and those affected might tiredness during the day. This

The appropriate answer is d. Dead plants in a swampy environment is the perfect environment for the beginning of the coal forming process. Over time layers pile up in this anaerobic environment. The plant or organic material gets buried overtime by dirt or rocks. Millions of years of burial will expose the matter to heat and pressure and will eventually lead to the formation of coal and other petroleum products.
The answer should be C, It diffuses from the alveoli into the blood.
Alveoli, also called the air sac, is the place where the oxygen we breathed in is exchanged with carbon dioxide that our body produces. Oxygen is passed into the blood in the capillaries through the process of diffusion, while carbon dioxide is diffused from the blood back to the alveoli, so that we can exhale the carbon dioxide after that.
Both a and b are not right because when we breathe in, the oxygen travels from the trachea to the bronchi, to the bronchiole, and to the alveoli, instead of directly into blood vessels like arteries, capillaries, or veins. d is also not right because the direction is wrong.
Therefore, your answer should be C.
