Many of our physiological functions, such as heart beat frequency, hormone secretion or body temperature, are regulated by internal clocks. Most of our body's cells possess one of them, formed by a group of 'clock genes' displaying a cyclic activity that peaks every twenty-four hours. These...
Socially thermoregulated thinking: How past experiences matter in thinking about our loved onesBody temperature regulation is of crucial importance for nonhuman and human animals. Because other animals are crucial in helping to regulate body temperature, temperature differences likely determine how humans ...
Ongoing research by Prof. Lewis Halsey and his team at the University of Roehampton, UK has identified that an upper critical temperature (UCT) exists for humans and is likely to be between 40°C (104°F) and 50°C (122°F). Further research is now underway to explain this rise in me...
14. Can humans make intense lasers with incoherence comparable to sunlight? 14.人类能制造出与太阳光相似的非相干强激光吗? 15. What is the maximum speed to which we can accelerate a particle? 15.我们最多可以将粒子加速到多快? 16. Is quantum many-body entanglement more fundamental than quantum ...
Now, the team will address a “big unanswered question,” namely, “whether it is the operation of circadian clocks in the hippocampus that is directly regulated by shifts in the light-dark cycle, or whether neurogenesis is controlled by biological clocks that work in cel...
What are the three factors that affect the metabolic rate of humans? Explain your answer. How is the respiratory system regulated? How does the human body control its temperature through homeostasis? What is the function of cofactors in cell metabolism?
Keeping your body temperature low is key to avoiding the more destructive effects of heat. The NHS advises that taking a cool dip or morning shower will keep your body heat regulated. Applying ice to the wrists and side of the neck can also help as the blood vessels in those areas ...
All of these tasks are coordinated, controlled and regulated by an organ that is about the size of a small head of cauliflower. Your brain, spinal cord and peripheral nerves make up a complex, integrated information-processing and control system known as yourcentral nervous system. In tandem, ...
With the intensification of the greenhouse effect, a series of natural phenomena, such as global warming, are gradually recognized; when the ambient temperature increases to the extent that it causes heat stress in plants, agricultural production will in
How does digestion take place in human beings? How does the digestive system interact with other body systems, in order to maintain homeostasis? What regulates eating behavior in humans? How is the exit of food material from the stomach regulated? Where does it go?
