5.	List the name of diseases at least 10 and write the name of pathogen from which this disease is caused
Answer» Answer: In biology, a pathogen (Greek: πάθος pathos "suffering", "passion" and -γενής -genēs "producer of") in the oldest and broadest sense, is anything that can produce disease. A pathogen may also be REFERRED to as an infectious agent, or simply a germ. The term pathogen came into use in the 1880s.[1][2] TYPICALLY, the term is used to describe an infectious microorganism or agent, such as a virus, bacterium, PROTOZOAN, prion, viroid, or fungus.[3][4][5] Small animals, such as certain kinds of worms and insect larvae, can also produce disease. However, these animals are USUALLY, in common parlance, referred to as parasites rather than pathogens. The scientific study of microscopic organisms, including microscopic pathogenic organisms, is called microbiology, while the study of disease that may INCLUDE these pathogens is called pathology. Parasitology, meanwhile, is the scientific study of parasites and the organisms that host them. There are several pathways through which pathogens can invade a host. The principal pathways have different episodic time frames, but soil has the longest or most persistent potential for harboring a pathogen. Diseases in humans that are caused by infectious agents are known as pathogenic diseases, though not all diseases are caused by pathogens. Some diseases, such as Huntington's disease, are caused by inheritance of abnormal genes

Distance traveled by the bus in one hour = km

Answer»

Answer:

It depends on the speed of the bus.

But take the normal CONDITION, the bus is travelling with 40km PER hour

Now you can apply the formula

Distance = Speed × Time

1km = 40 Km/HR × Time

Time = 1/40 hr = 0.025 hr or 1.5 min

You can apply this formula to FIND the time.

Answer» Answer: When you have acidic saliva, your smile will likely suffer from acid erosion, which can ultimately lead to enamel loss, tooth decay, and cavities. On the other HAND, studies have shown that an alkaline pH level in your mouth can increase BONE density and enamel strength. Soil pH is important because it influences several soil factors affecting plant growth, such as (1) soil bacteria, (2) nutrient leaching, (3) nutrient availability, (4) toxic elements, and (5) soil structure. ... Aluminum may become toxic to plant growth in certain soils with a pH below 5.0. If the pH of water is too high or too low, the aquatic organisms living within it will die. pH can also affect the solubility and TOXICITY of chemicals and HEAVY metals in the water ¹². ... The optimum pH levels for fish are from 6.5 to 9.0. Outside of optimum RANGES, organisms can become stressed or die. Explanation: I hope that it would be helpful.

Calculate pressure if the force applied is 1000 N and area of contact is 50 meter squares.

Answer»

Answer:

20 Pa or 20 N/ METER SQUARE

Explanation

AS WE KNOW THAT, PRESSURE=FORCE/AREA

SO, OUR FORCE= 1000N

AND OUR AREA= 50 METER SQUARE

SO, PRESSURE WILL BE 1000/50 METER SQUARE

AND IF YOU WILL CALCULATE, YOU WILL GET 20N/METER SQUARE
AND WE CAN ALSO WRITE 20 N/ METER SQUARE AS 20 Pa.

HOPE IT WILL HELP YOU.

THANKS.
