The plains are dry for much of the year, there is some rainforest, and the rest of the country includes both hills and mountains. There are two seasons of heavy rainfall. Sangala has a pluralistic health system that is made up of public and private institutions, publicly financed providers, licensed private providers, unlicensed medical practitioners, and traditional healers. There is no health insurance, except for some free services for the poor in the few publicly financed hospitals, which the better off people do not attend. The health system is not very effective or efficient and is generally of low quality. The HIV, TB, and malaria programs are not effective or efficient and they are just beginning to adopt paradigms for services that follow global best practices. If you were interested in investing in maternal and child health using a results-based financing scheme, which program is the most appropriate?A. Invest in training more skilled birth attendants in a village. B. A plan to give the local clinic in the village a grant after the clinic demonstrates that its efforts have led after two years to lower under-5 child mortality. C. Provide all pregnant women in the village with a full course of antenatal vitamins. In Sangala today, approximately what proportion of the burden of disease, measured in DALYs, is likely to be Group I-related?A. 45%B. 35%C. 60%In Sangala, life expectancy fell in the 1990s, which can be attributed to:.A. MalariaB. HIVC. PneumoniaIn Sangala, the cost for treating severe diarrhea in young children is $18 for community-based care and $20 for clinic-based care. The cure rate for community-based care is 60%. The cure rate for clinic-based care is 90%. Which approach is the most cost-effective?A. Community-based careB. Clinic-based careC. They are equally cost-effectiveIn Sangala, what are likely to be three of the five leading causes of death of under-5 children, besides perinatal causes?A. TB, diarrhea, pneumoniaB. Malaria, diarrhea, measlesC. Diarrhea, malaria, pneumonia

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#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.

bacteria could be both, harmful and to us. harmful bacteria could make us sick and probably even by getting the chances of getting a disease, but good bacteria fight it off with your immune system. there is always bacteria everywhere we go. we need to make sure to wash our hands after using the restroom, before eating, after eating, after petting an animal too. so you see, bacteria is everywhere and is harmful or . i hope this . : ) : ) : )
