The main function of the <u>respiratory system is breathing</u>, a process that is also referred to as respiration. This

process allows the body to bring in oxygen and expel (get rid of) carbon dioxide. During respiration, oxygen travels

through the bloodstream and carbon dioxide is carried away.

Breathing air into your body is also necessary for <u>speaking</u>.

PLS HELP ASAP<br> decribe the importance of agriculture of the people in central america
sasho [114]

Their progress and wealth is highly dependent on the harvests, and the price of grain. They probably have to import some industrial products and if they had a bad year (weather, other catastrophies, poor technology) they can't get the necessary amount of industrial products in exchange for their surplus e. g. in grain. There are so many standards and requirements about the quality of food production that no country can survive solely on agriculture without high quality technology (machines, unharmful fertilizers, research-based breeding, etc.).

the oldest rocks on earth date from about 4.2 billion years ago. what does this suggest about the interval between 4.6 billion y
aivan3 [116]

Answer:

The Hadean eon represents the time interval between 4.6 billion to 4 billion years back. It is marked by the initial formation of the earth , right from the time of gathering and accumulation of interstellar dust particles and gases, and there was frequent collision between the planetesimals of relatively larger in size. The core and the crust formed and started to become stable and also gradually led to the formation and expansion of the ocean and the earth's atmosphere.

This is how the earth gradually started to form and develop and took the shape during the time interval between 4.6 billion to 4.2 billion years old, and where the oldest rocks found on earth is dated from about 4.2 billion years in the past.

umka2103 [35]

Answer:

a) w = 98°

b) x = 137°

Explanation:

The reason is that they are angles at a point

Which means they are equal to 360°.

Example;

a) 165° + 97° + w = 360°

262° + w = 360°

You then group like terms

w = 360° - 262°

w = 98°

Note: The reason is the same for b)

Identify the false statement.
stepan [7]

Answer:

A. Weathering, vegetation covering, and water influence the stability of a slope.

Explanation:

  • As water tends to flow down by the act of gravity the flow of the water down the slope will make the unconsolidated sediments to flow down the slope and thereby making the slope more prone to weathering and not stabilization it hence the flow tends to move down the rocks, silt and loose particles and thus making it me prone to weathering and erosion.
  • <u>Thus the flowage of the matter will create more impacts on the slope angle and width as it will spread more faster and extensively.</u>
