In photosynthesis, ATP and NADPH are produced during the light-dependent phase. It is the energy from the light propels the electrons into a high energy state from a photosystem. It is basically converted into chemical energy as ATP and NADPH, it is represented the what do we call Z-scheme.
Answer:
a. suprachiasmatic nucleus.
Explanation:
The circadian rhythm is an internal process that regulates daily cycle (sleep/wake conditions through the 24 hours). This process is performed by circadian clock which is located in hypothalamus, in the suprachiasmatic nucleus. It has been shown that when the suprachiasmatic nucleus is destroyed, regular sleep–wake rhythm is lost.
The suprachiasmatic nucleus sends information to the pineal gland, which secretes hormone melatonin (regulator of sleep–wake cycle).
Cigarette smoking and environmental chemicals
Tobacco smoke and certain environmental chemicals are known carcinogens (substances that can cause cancer in living tissue). The tobacco smoke from cigarette smoking contains harmful chemicals such as hydrogen cyanide, arsenic, ammonia, benzene, and many more. In fact, from 2009 to 2013, three out of 10 cancer deaths in the U.S have been attributed to cigarette smoking or exposure to tobacco smoke.
