In prophase, DNA begins to cluster. In metaphase, two identical, condensed DNA strands line themselves up in the middle of the cell. After metaphase, there are: Anaphase, Telophase, and Cytokinesis. This process excluding or including Cytokinesis is called mitosis.
In the DNA replication for a cell baby, meiosis occurs.
The end result: Atoms with six protons and six neutrons — carbon. ... It can also bond with up to four other atoms because of its electron arrangement. Atoms are arranged as a nucleus surrounded by an electron cloud, with electrons zinging around at different distances from the nucleus
Answer:
Option (D)
Explanation:
In terms of chemistry, a catalyst is usually defined as the substance that is commonly used in a reaction in order to increase the rate of reaction, without getting consumed. It helps in the reduction of activation energy.
In the given case, the lever or a person can be considered as a catalyst because both of these will increase the efficiency (or rate) in removing the rock from the top of the perch. Thus, the lever or the human will remain the same after the removal of rock as a catalyst can be recovered after the reaction.
Therefore, the correct answer is option (D).
ATP - Adenosine Tri-phosphate. The element is an energy source that fuels many of the biological processes in both humans and other organisms, even plants. The most important element is the tri-phosphate.
