<h3><u>Answer;</u></h3>
D) <em>The more dense oceanic plate subducts under the less dense continental plate. Subducted plate melts due to heat and friction. Melted plate, now magma, rises up to the surface.</em>
<h3><u>Explanation</u>;</h3>
- <em><u>Volcanoes may be formed at convergent plate boundaries or at divergent plate boundaries. </u></em>
- <em><u>When two tectonic plates collide, they form a convergent plate boundary. Normally, one of the converging plates that is the dense oceanic plate will move beneath the other, which is the less dense continental plate a process as subduction. </u></em>
- <em><u>The friction between the plates in the subduction zone as a result of constant movement, melts the Earth's crust causing the underneath rocks to turn into magma.</u></em>
- <em><u>The magma creates great pressure and rises towards the surface of the earth, and on reaching the surface it is called lava, and a volcano is formed.</u></em>
Answer:
A. oxygen and sugar are used in the process that provides energy to cells, water and carbon dioxide are given off.
Explanation:Respiration is a biochemical process that uses oxygen and glucose to generate energy with the release of carbondioxide and water. All organism respires and the oxygen is used for cellular respiration.
C6H1206 +6O2----6CO2+6H2O+Atp(energy)
The Co2 and H2O is used by plant for the process of photosynthesis in producing there food.
Answer:
<u>The process of photosynthesis occurs in the chloroplast</u>. Photosynthesis can be described as a process in which plants convert water and carbon dioxide into glucose and oxygen. Oxygen is the by-product of the reaction. The energy for this reaction is taken by the chloroplast by trapping light energy of the Sun.
The reaction for photosynthesis can be written as:
6CO2 + 6H2O → C6H12O6 + 6O2
<u>The process of cellular respiration takes place in the mitochondria.</u> Respiration can be described as a process in which glucose and oxygen get converted into carbon dioxide and water. Energy is released by this process which is used for many cellular activities. Hence, mitochondria is known as the powerhouse of a cell.
The reaction of cellular respiration can be summed up as:
C 6 H 12 O 6 + 6 O 2 --> 6 CO 2 + 6 H 2 O + ATP
Both, these processes provide energy for the working of cells.
Since a prokaryotic cell does not have a nucleus the DNA will be found floating around in the cytoplasm. This often is referred to as the nucleoid.
