The human genome project is devoted to mapping the general dna sequence of our species. this could lead to the development of new medicines, as well as the possibility of using gene therapy to treat certain diseases. however, there are some ethical issues surrounding the mapping of individual genomes. one concern is a) that your genes may change over time, making the project useless. b) that since this has never been done before, we should probably not do it now. c) that employers may discriminate against people who have genes linked to certain illnesses. d) that sequencing our individual genomes is so expensive, it is a counter-productive strategy.

The correct answer is option C.

Human genome project is devoted in mapping the DNA sequence and the the ethical issues that is related to this project is that the employers might deny to work with the people having certain kind of illness in their body that is associated with the genes. The people working together might discriminate the person having illness.

This is the reason that the data is kept confidential.

Option C, that employers may discriminate against people who have genes linked to certain illnesses.

Explanation:

Though the objective of human genome project is to advance clinical and scientific investigation on 3 billion base pairs exiting in human beings, experts have raised concern over the data & information secrecy and ethical issues associated with it.  

One of the major issues is associated with the discrimination based on the genetic history or any prevailing genetic disease in family. The insurances companies may not provide medical insurance to such people or families who have a genetically diseased background. However, in present time these insurance companies limit their benefits to an individual or family with medical history. Also, there can be cases of job discrimination at workplace or discrimination at place of accommodation by the local residents etc.  

Hence, option C is correct

question#1

ans:

cell is the basic unit of organization of all living things. cells are often called the building block of life and it is the smallest unit of life. the study of cell is called cell biology. cell consists of cytoplasm enclosed within membrane, which contain bio-molecules such as proteins and nucleic acid.

two third of cell is water, which means that two-third of your whole body is water. the rest is the mixture of molecules, mainly proteins, lipids and carbohydrates.

question#2

ans:

organ:

an organ is a group of tissues specialized to form a functional unit. an example is the heart in animals.

organ system:

an organ system is a group of several organs whose functions are synchronized to release an effective action in a living organism. an example is digestive system.

question#3

different systems perform different function at tissue level. for example, the respiratory system facilitates breathing. in the alveoli tissue of the lungs, the exchange of oxygen and carbon dioxide molecules between the air and the bloodstream occurs by passive transport, so that oxygen is taken in and carbon dioxide and water are removed. different systems of the body carry out different functions. for example, your digestive system is responsible for taking in and processing food, while your respiratory system working with your circulatory system is responsible for taking up oxygen and getting rid of carbon dioxide.

question#4

different systems perform different function at tissue level. for example, the respiratory system facilitates breathing. in the alveoli tissue of the lungs, the exchange of oxygen and carbon dioxide molecules between the air and the bloodstream occurs by passive transport, so that oxygen is taken in and carbon dioxide and water are removed. different systems of the body carry out different functions. for example, your digestive system is responsible for taking in and processing food, while your respiratory system—working with your circulatory system is responsible for taking up oxygen and getting rid of carbon dioxide.

question#5

our body works because of the interactions that happen between organs and organ systems.  

for example:  

the heart to regulate blood flow throughout the body. the blood carries oxygen and nutrients to the cells and carries carbon dioxide and waste away from the cells. body systems work together in maintaining a constant internal environment. when this balance is disrupted, the body systems may not function properly, and human health can suffer.   you start to feel bad.
