Question

Differenciate between intracellular and extra cellular dijestion

Answer 1

Answer:

Global warming is the long-term heating of Earth’s climate system observed since the pre-industrial period (between 1850 and 1900) due to human activities, primarily fossil fuel burning, which increases heat-trapping greenhouse gas levels in Earth’s atmosphere. The term is frequently used interchangeably with the term climate change, though the latter refers to both human- and naturally produced warming and the effects it has on our planet. It is most commonly measured as the average increase in Earth’s global surface temperature.

Since the pre-industrial period, human activities are estimated to have increased Earth’s global average temperature by about 1 degree Celsius (1.8 degrees Fahrenheit), a number that is currently increasing by 0.2 degrees Celsius (0.36 degrees Fahrenheit) per decade. Most of the current warming trend is extremely likely (greater than 95 percent probability) the result of human activity since the 1950s and is proceeding at an unprecedented rate over decades to millennia.

Answer 2

Difference between intracellular and extra cellular digestion are as follows :

Intracellular Digestion :

• The digestion of food occurs within the cell.
• Digestive enzymes are secreted by the surrounding cytoplasm into the food vacuoles.
• It is a less efficient method.
• It occurs in unicellular protozoans and sponges.
• Digestive products are diffused into the cytoplasm.

Extracellular Digestion :

• The digestion of food occurs in the cavity of alimentary canal.
• Digestive enzymes are secreted by special cells into the cavity of alimentary canal.
• It is a more efficient method of digestion.
• It occurs in multicellular organisms.
• Digestive products diffuse across the intestinal wall into various parts of the body.
