Explanation:
ATP is the main energy-storing molecule found in all living organisms. It transports the energy necessary for all cellular metabolic activities. It is made through the process of photosynthesis using energy from sunlight, or through the process of cellular respiration in the mitochondria of a cell.
Hope this helps!!
Answer:
Smaller
Explanation:
If they were smaller they would have less to pull to, so then you would see them start to drift and fly away from each other
Answer:
d. Plant cells contain a large vacuole that occupies much of the volume of the cell.
Explanation:
The vacuole is a membrane-bound organelle which is often found in plant and fungi cells, as well as in certain bacteria, protists and animal cells. The vacuole is filled with water that forms a solution containing inorganic and organic compounds. The size of the vacuole may vary depending on the requirements of the specific cell type. In plant cells, vacuoles often occupy an important fraction of the overall cell volume and play key roles during growth and development, influencing diverse cellular functions ranging from photosynthesis to transpiration.
Answer:
Nearly 50%
Explanation:
The earth about 8000 years back was comprised of almost 6 billion hectares of forest-covered land. And according to the research, it has been observed that nearly 50% of the initially forest-covered region has been reduced, which has now become about 3 billion hectares.
These forests are being cut down for various purposes, such as construction of urban areas, construction of wooden houses, making furniture, overgrazing of animals, forest fire. It causes both naturally as well as due to anthropogenic activities.
Thus, nearly 50% of the forest is reduced in the last 8000 years.
