Using your knowledge of fungi, which of the following might prevent the mold from growing? A. Buy a different type of orange. B. Keep the oranges in the refrigerator. C. Put the oranges in a warm place. D. Put the oranges in a damp place. Which of the following diseases is caused by a bacteria? A. Chicken pox B. Tuberculosis C.. Dengue D. Polio Partial sterilization of a product such as milk at a high temperature is known as A. Pasteurization B. Filtration C. Pickling D. Refrigeration are the agents that act as carriers of a pathogen and spread diseases. A. Vectors B. Microbes C. Parasites D. DNA

Mold grows best in warm, humid environments. So, I think B is the correct answer. Answers C and D would actually encourage the growth of mold.

I know that B (Tuberculosis) is spread by bacteria.

Pasteurization is the process where milk is heated up to kill certain pathogens.

Finally, vectors are the agents that carry pathogens from one person to another and spread disease.

the scientific method.

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.
