Maintain a weight below the normal range.
Answer:
The person who could have done more to reduce the hepatitis outbreak would be the governor of the region where the outbreak was reported.
He should have installed a strong inspection system to monitor the hygiene of the food supplied to the population, in addition to water hygiene. An efficient basic sanitation system and a vaccination campaign could also be carried out.
This was probably not due to political negligence, lack of public policies and lack of information for the population.
Explanation:
There are many types of hepatitis, with different forms of infection. However, the most common hepatitis is one that is transmitted by eating contaminated food and water.
In order to prevent this contagion from spreading in a city, the government official must establish a strong inspection of the quality of the water and food offered to the population. In addition, it is necessary that a strong basic sanitation system be implemented in the region, reducing cases of poor quality water. It is also important to inform the population about the risks of the disease and the ways to contract it, lastly, it is important that there is a vaccination campaign against the disease.
In many regions, government officials are negligent and do not provide basic public policy projects that can prevent an outbreak of hepatitis from taking over a region.
Answer:
There are five principles of fitness out of which two are overload principle and rest and recovery principle. Overload principle is one of the most important principle which tell that to gain and improve the fitness one should do the hard work.
Slowly and gradually the intensity and time of exercise are increased so that our body can adapt to the hard work. Overload principle plays an important role in improving the skills and improving performance during exercise and sports.
Rest and recovery principle is important to relax the body and release the stress that happens due to intense training like in case of weight lifting one day rest should be taken to repair and rebuild the muscles. This allows the body to encounter the fatigue and improve performance.
Answer:
False
Explanation:
Testicular cancer almost always occurs in one testis but can occur in both as well (but not almost always). Caught early there is a 95% survival rate as it rarely spreads to other organs.
1. change
The natural selection is a process that occurs as a direct consequence of the living conditions in the environment. When the environment starts to change though, the organisms that live in it face a big challenge. They either have to change, adapt to the new conditions, and thus survive, or if they are not able to do so, to die out. This is the biggest evolutionary pressure for the organisms, and while some come out as winners from it, many others die out .
2. variation
In order for the process of natural selection to occur, the population needs to have some genetic variation. The environment is the ultimate push factor, but if the population doesn't have genetic variation in it, than the species will die out. The genetic variation is very important as in that way the individuals choose who will they mate with, in accordance with their traits, so that only the advantageous traits can be passed on to the next generation, so that it can be more competitive in the environment.
3. traits
The natural selection is a very simple process. The individuals of a population, when choosing a mate, look for the individuals that exhibit traits that are advantageous for survival. Mating with individuals with traits that are advantageous guarantees that the offspring will inherit those traits, thus it will have higher chances to survive. The individuals that do not have advantageous traits though will be avoided as mating partners, and that would rapidly lead to their decline and elimination from the gene pool, as they will not have any offspring to continue their line.
