Answer:

  • Gases from Earth's surface form the atmosphere
  • Earth's surface cools
  • Photosynthetic organisms absorb atmospheric carbon dioxide and release oxygen
  • The composition of Earth's atmosphere changes.
  • Organisms with aerobic metabolism evolve

Explanation:

According to the <u>chemosynthetic hypothesis of the origin of life</u>, gases such as methane, hydrogen, water vapor, etc. that emanate from the earth's interior formed the atmosphere of the primitive earth.

The earth's surface was characterized by volcanic activities and as it cools down, the water vapor in the atmosphere began to condense and form puddles of water on the surface of the earth. A chemical soup was later formed from the dissolution of the atmospheric gases catalyzed by heat, lightning discharge, and UV rays.

From the chemical soup, the first organism with heterotrophic metabolism evolved, and as the evolution continued and resources became limited, autotrophic organisms emerged and are able to utilize carbon dioxide and water to photosynthesize and release oxygen as a by-product.

As oxygen gradually gets to the atmosphere, the composition of the earth's atmosphere changed and organisms with aerobic metabolism evolved.

The journey of the food through the digestive system will actually digest the food. The rest will be given out as feces.

<h3><u>Explanation:</u></h3>

The digestive system actually consists of digestive tract and Digestive glands. The processes that are associated with digestive system is - ingestion, digestion, absorption, assimilation and egestion.

The food that is taken is first smashed and chewed into a rough bolus by mixing with saliva. The salivary amylase slightly digests the starch into dextrin.

Then the food is engulfed through the oesophagus into stomach. Inside stomach, the food is mixed with an enzyme pepsin and HCl. Pepsin digests the proteins into peptones and peptides. The food is converted into a bolus and transported into duodenum.

In duodenum, there are several enzymes from small intestine and pancreas breaks the fats into fatty acids, proteins into peptides and starch into carbohydrates like glucose. They are absorbed and the undigested substances are left over ad feces.

zhannawk [14.2K]

Answer:

Transpiration is the process of water movement through a plant and its evaporation from aerial parts, such as leaves, stems and flowers. Water is necessary for plants but only a small amount of water taken up by the roots is used for growth and metabolism. The remaining 97–99.5% is lost by transpiration and guttation.
