Name waterborne and airborne diseases.Distinguish them in 8 to 10 points.What are the precautionary methods to prevent these diseases?
Answer:
waterborne diseases:cholera, diarrhea, typhoid, amebiasis, hepatitis, gastroenteritis, giardiasis,
airborne diseases:
difference:Airborne diseases are spread when droplets of pathogens are expelled into the air due to coughing, sneezing or talking. Water-borne disease is any disease that is caused by pathogenic microorganisms and most commonly transmitted through contact or consumption of infected water.
HOW TO PREVENT AIRBORNE DISEASES:Avoid close contact with people who have active symptoms of disease.
Stay home when you're sick. .
If you must be around others, wear a face mask to prevent spreading or breathing in germs.
Cover your mouth when you cough or sneeze.
HOW TO PREVENT WATERBORNE DISEASES:Drink only filtered/boiled water.
Store water in a clean container,
Water jars/containers should be washed daily.
Always wash hands before and after preparing food or eating, likewise, children should be taught on hand washing.
P.S. hv a wonderful weekend!

The ability of an animal to maintain a stable internal environment is called
.
Answer: Homeostasis
Homeostasis is the way animals maintain a stable internal balance in their body. It allows animals to function in the changing external conditions surrounding their body. Homeostasis is important to Chinook salmon because they depend on the functioning of its cells to help its survival and ability to reproduce.

Is the way animals maintain a stable internal balance in their body. It allows animals to function in the changing external conditions surrounding their body.
Answer: Scientific questions are those questions that can be answered through observation of world around us and by experimentation.
Explanation:
The scientific questions related to the earth and the space science are as follows:
1. How the celestial bodies like moon, sun, and others affect the functioning of the earth?
2. How earth is different from other planets in the space?
3. What is the distance covered by the earth from other celestial bodies including other planets in the solar system?
4. How asteroids and meteors affect the earth?
5. Why different regions of the earth receive different intensities of light from the sun?
Explanation:
Ans1:-)Gravity is the force that connects every object - planet, the Sun, moons, asteriods, comets - to every other object. The Earth is constantly being tugged by all the other bodies in the solar system. Except for the Sun and the Moon, most bodies are either too small or too
Ans2:-)Earth is one special planet. It has liquid water, plate tectonics, and an atmosphere that shelters it from the worst of the sun's rays. But many scientists agree our planet's most special feature might just be us. ... The fact that Earth hosts not just life, but intelligent life, makes it doubly unique
Ans3:-)For objects within the solar system, distances are calculated from their orbital parameters and are center to center distances. For objects outside of the solar system, those objects are so far away that there is no discernable difference between the center to center distance and the surface to surface distance.
Ans4:-)Such collisions could have caused the larger bodies to be broken up into the smaller objects we observe as meteorites. Much evidence suggests that the asteroids could be the parent bodies of meteorites.
Ans5:-)Because of the Earth's tilt the sun's rays strike the surface at a slant at the poles; they are less focused. ... The tilt of the Earth causes different areas to receive different amounts of solar energy. The difference in solar energy received at different latitudes drives atmospheric circulation.

What happens when the thermal energy of a substance increases?
The motion of the particles in the substance increases, and the temperature of the substance decreases.
The motion of the particles in the substance decreases, and the temperature of the substance increases.
Both the motion of the particles in the substance and the temperature of the substance decrease.
Both the motion of the particles in the substance and the temperature of the substance increase.
