1. The central nervous system including brain and spinal cord.
2. The peripheral nervous system including nerves coming out from the brain and spinal cord, i.e., cranial nerves and spinal nerves.
3. The autonomic nervous system including sympathetic nervous system and parasympathetic nervous system.
Answer: In an ionic bond the valence electrons are transferred from the metal only to the neighboring nonmetal, but in metallic bonding the valence electrons of each atom/ion are free to move or float around within the entire metal solid.
Explanation:
Environment:
Science helps the environment because it creates an understanding between human impacts and the environment. By gaining this understanding of how the natural world works, the human race will better know how to protect it. In addition, scientific research is being used to reduce the impact of global warming, adapt to climate change, clean up polluted areas, and protect our own health.
Health:
Science can be used to improve global health because it fuels discovery, informs the public on health risks and programs, and helps all people live healthier and better lives. People with physical and mental health can benefit greatly from a variety of health sciences that specialize in their specific ailment. There have also been improvements in the technology used in health such as sanitation, vaccinations, and monitoring systems. By enabling doctors to do minimally invasive surgeries and using more comfortable scanning equipment, patients spend less time recuperating and can spend more time doing what they enjoy.
Peace:
It is my opinion that communication is the main way that science influences peace. Scientists from all over the world collaborate in an unbiased way to focus on one main goal, to deliver scientific breakthroughs to people regardless of religion, race and culture. Furthermore, science contributes to the social and economic development in a society (such as GDP, life expectancy, and literacy), reduction of poverty (through new was to meet basic needs for food, clothing, and shelter), and inspires a newfound peace mindset.
Equity:
Peace is a strong piece of science and, therefore, equity. Science is heavily rooted in the creation of new knowledge, the improvement of education, and the improvement of the quality of human life regardless of bias. Because of this, science can be used to research and find ways to solve pressing issues like racial and economic inequity. Learning of science in schools also has an impact on equity by teaching children the basis of our world and how to understand in order to gain skills that lead to better economic and social outcomes.
Germ-line mutations are mutations that would be passed down to future generations, and recombinations are where the information each parent passes down to the offspring is shuffled.
The genetic variation would have to come from random events: False
Only alternate generations would express any genetic variable: False
Body cell mutations would be the only source of heritable genetic variation: False
There would be no new heritable genetic variation possible in the population: True
Answer:
Photoperiodism
Explanation:
The term "photoperiodism" was coined to describe a plant's ability to flower in response to changes in the photoperiod: the relative lengths of day and night. Because flowers produce seeds, flowering is crucially important for the plant to complete its life cycle.
