Answer:
Valence electrons are basically electrons in the outermost shell of an element.
When the lysosomes of a cell rapidly digest the cell itself, this process is known as autolysis. This self digestion process helps in the decomposition of the dead cells. The cell is dismantled by its own lysosomes, which digests the remains of the dead cell. It is an essential process in the life cycle of a cell. This self digestion of the cells is extremely important for the new cells to grow.
Hence, the correct answer is 'autolysis'.
Answer:
Physics is the natural science that studies matter, its motion and behavior through space and time, and the related entities of energy and force. Physics is one of the most fundamental scientific disciplines, and its main goal is to understand how the universe behaves.
The correct answer for this question would be repressible enzymes. Repressible enzymes are those which bind to the operator, and then block the attachment of RNA polymerase, which therefore prevents the transciption of genes. From this, we know that these are the types of enzymes that are synthesized in an environment where an operon is needed to code for enzymes that synthesize a protein from precursor amino acid molecules.
Answer:
raised atmospheric concentrations of CO2 by 47% above pre-industrial levels
Explanation:
Over the past 170 years, human activities have raised atmospheric concentrations of CO2 by 47% above pre-industrial levels found in 1850. This is more than what had happened naturally over a 20,000 year period (from the Last Glacial Maximum to 1850, from 185 ppm to 280 ppm).
