Answer: B
Explanation: It goes to the stomach where the nutrients are gathered and sent to cells
In Sexual reproduction evolution takes place.
Explanation:
In sexual reproduction, the gametes from the two parents fuse to form a zygote and consequently an organism. The gametes from the two parents provide different alleles for a trait. The different genetic variant or alleles found will cause genetic variation.
The offspring can survive and adapt to the new environment. This leads to natural selection and evolution.
In asexual reproduction changes only occur if mutation takes place otherwise the progeny remains genetically identical so less chance of evolution.
Analogous are the organs having similar function but different origin in different organisms.
Detrimental effects are small or negligible effect of mutation on organism due to the exposure of chemicals or rays.
Only those mutations are heritable which occur in germ cells, mutations of somatic cell do no pass to other generation. Detrimental effect is mainly seen in somatic cells.
Answer:
Yes.
Explanation:
Recent developments in biology have made it possible to acquire more and more precise information concerning our genetic makeup. Although we have only begun to see the most far-reaching effects of these developments and the completion of the Human Genome Project, scientists can even today identify a number of genetic disorders that may cause illness and disease in their carriers. The improved knowledge regarding the human genome will, it is predicted, soon make diagnoses more accurate, treatments more effective, and thereby considerably reduce and prevent unnecessary suffering. The knowledge can also be, however, depending on the case, futile, distressing, or plainly harmful. We propose to answer in this article the dual question: who should know about our genetic makeup and why? Through an analysis of prudential, moral, and legal grounds for acquiring the information, we conclude that, at least on the levels of law and social policy, practically nobody is either duty-bound to receive or entitled to have that knowledge.
