A ten mile area of trees is removed from the tropical rainforest. How will this affect the amount of water and the amount of oxygen in the area?

Answers

We know that the roots of the trees would absorb the water under the ground. This is necessary for photosynthesis. Photosynthesis would produce food for the tree and as by product, oxygen is produced. Removing the tree would decrease the water consumption but would also decrease the oxygen production. 

Removing the tree would decrease the water consumption but would also decrease the oxygen production.

What is a tropical rainforest?

Tropical rainforests are found in Central and South America, western and central Africa, western India, Southeast Asia, the island of New Guinea, and Australia.

Sunlight strikes the tropics almost straight on, producing intense solar energy that keeps temperatures high, between 21° and 30°C (70° and 85°F).

Deforestation has an adverse affect on air by reducing the amount of oxygen and increasing the amount of carbon dioxide as well as contributing to global warming.

What properties can you use to identify if a substance is salt, baking soda or cornstarch?

Answers

Answer:i believe its water, vinegar, and iodine solution... sorry if wrong

Explanation:

The cornstarch and water mixture acts like a solid sometimes and a liquid at other times. This concoction is an example of a suspension (a mixture of two substances), one of which is finely divided and dispersed in the other. ... When you slap the cornstarch quicksand, you force the long starch molecules closer together.

Many insulating materials contain spaces filled with air because air is what type of material?

Answers

Many insulating materials contain spaces filled with air because ; Air is a poor conductor of heat and electricity

Insulators are materials that do not allow the easy passage of heat  or electricity through them. they are used to protect users from direct exposure to electricity and heat and also for the protection of equipment's at home and at work places.

Insulators are generally bad conductors of heat and electricity. some examples of insulators are ;

  • Dry wood,
  • Air,
  • Porcelain,
  • Rubber,
  • Plastic and glass

They are all very good insulators. but the most commonly used insulator in electrical installations is Porcelain

Hence we can conclude that many insulating materials contain spaces filled with air because Air is a poor conductor of heat and electricity.

What is the approximate mass of a proton?(1) 1 u
(2) 0.0005 u 
(3) 1 g
(4) 0.0005 g

Answers

Mass of a proton is considered to be one mass unit. Thus, the mass of proton is taken as 1u.

Thus, the answer is (1) 1u

Final answer:

The mass of a proton is approximately 1 atomic mass unit (u). Among the options provided, the correct one is (1) 1 u. The mass of a proton is a known constant and does not change.

Explanation:

The mass of a proton is approximately 1 atomic mass unit (u). Atomic mass unit (u) is a standard unit of mass used to express atomic and molecular weights. Given the options provided, the correct answer would be (1) 1 u. The other options are not accurate because a proton's mass is a known constant in physics and chemistry and does not correspond to those values. It's important to remember that the mass of a fundamental particle like a proton remains constant and does not change.
