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.
Answer: B. An individual has an autoimmune disorder that destroys the beta cells of the pancreas.
C. An individual’s insulin receptors are defective.
Explanation:
Diabetes mellitus is a common disease. In this disease the level of sugar in the blood is affected. This occurs when pancreas does not produce enough insulin or the receptors involving insulin also become resistant to insulin, which is a sugar balancing hormone.
Type 1 diabetes involves the complete lack of production of insulin by the beta cells of the pancreas. The beta cells of pancreas are destroyed by the body's self immune system.
Type 2 diabetes involves the development of insulin resistance by the target cells of the body. The insulin secretes but cannot compensate for the increase in blood glucose levels due to due to defective receptors on target cells.
On the basis of above explanation, B. and C. are the correct options.
Answer and Explanation:
When we talk about reduction of costs in a sector such as the health sector, it is paramount that the decisions taken are wisely done and also the best possible. So that every possible need is met to the best capacity.
For the needy, stopping treatment is wrong and should not be done. When there is an adjustment in budget, then a bit of prices could be put on some certain things which have high costs. A limit can be set on the frequency at which a person can visit the camp.
One criteria that can never be neglected is hiring skilled professionals and this should never be violated. The standard of care should not be limited.
In a private firm this decision could be different since funds may be high and better also advanced and better equipments may be afforded.
