The answer is R horizon.
The soil is made up of layers, called horizons, which are parallel to soil crust. These horizons are from top to bottom:
O - contains organic matter.
A - contains organic matter mixed mineral matter.
B - contains accumulated mineral or organic compounds.
<u>C</u> - consists of parental material.
<u>R</u> - consists of bedrock, masses of hard rock.
Thus, R horizon is below the C horizon.
<h3><u>Answer;</u></h3>
<em>Centrioles </em>
<h3><u>Explanation;</u></h3>
- <em><u>Centrioles</u></em> are organelles that are only found in animal cells.
- <u><em>Centrioles are important organelles that functions by helping the process of cell division in animal cells.</em></u> This is by helping the formation of spindle fibers whose role is to separate chromosomes during cell division.
- Additionally, <em><u>centrioles also play a very important role in celiogenesis, the formation of cilia and flagella on the surface of cells.</u></em> The cilia and flagella enhance the movement of cells.
C) The number of primary consumers will increase because since the wolf snake and hawk are gone, there won't be anybody who will eat the primary consumers aka grasshopper and rabbit
Hope this helps!
The correct answer is: D) H2O… CO2
Redox reactions are reactions of reduction (molecules tend to gain electrons) and oxidation (molecules tend to lose electrons).
Photosynthesis is a set of redox reactions. In photosynthesis electrons are removed from water (H2O) to carbon dioxide CO2 and then used to turn CO2 into organic compounds.
The first step: Oxygen in water is oxidized (light energy required)
The second step: Carbon in CO2 is reduced; sugar is formed (dark reaction).
Answer:
Cellular respiration uses energy in glucose to make ATP. Aerobic (“oxygen-using”) respiration occurs in three stages: glycolysis, the Krebs cycle, and electron transport. In glycolysis, glucose is split into two molecules of pyruvate. ... Life first evolved in the absence of oxygen, and glycolysis does not require oxygen.
