The mutation will occur often in offspring and leads to development of genetic variability in the gene pool.
Answer: C
Explanation:
Mutation refers to the process which causes disturbances in the normal DNA pattern.
When such phenomenon occurs over many generations, it will become a common process in offspring and increase the chance of difference in variability in the genetic makeup as well as the gene pool.
It is because, the first stage of mutation appears tedious to the organism.
As it gets transferred from one generation to another generation, the species due to its capability identifies certain ways and exhibit genetic variability due to the mutation.
By this way the mutation will become more common in offspring as their parent have mated in the presence of mutation.
Answer: c. The overuse of renewable resources can lead to problems similar to those associated with the use of nonrenewable resources.
Renewable resources are those resources, which can be replenished after once used such as wind, water, sunlight and others. Non- renewable resources are those resources, which cannot be replenished after once used, for example fossil fuels like coal, petroleum and natural gas.
Although, renewable resources are abundantly available in nature but their judicious use is necessary, so that these resources can meet the needs of the future generation, ensuring sustainable development of human society. But, in reality the overuse of renewable resources can lead to problems similar to those associated with the use of nonrenewable resources. This is because of increasing population and pollution in the environment, has deteriorated the quality and decreased quantity of renewable resources.
Answer:
the procedure aims to replace the stem cells in the bone marrow the source of new red blood cells with healthy stem cells from a matching donor
Bird sounds are made in the syrinx, but of course, the air sacs, passageways and the bird's lungs, also contribute to the production of sounds.
When birds start to sing,the 2 passageways between the lung and the syrinx, closes. Then, the sir is squeezed into the air sacs by the chest muscles. Squeezing the air sacs that surrounds the syrinx forces each of the two thin membranes in the syrinx into the 2 passageways between the lung and the syrinx.This process does not allow air to travel through.Afterwhich, muscles around the syrinx contract and tighten one membrane and pulls it out into the passageway (1 of the passageway). Air in that passageway can now move,which passes quickly over the membrane. That fast moving air causes a vibration, thus, sound is produced.
