The correct option is B.
A positive feed back refers to the amplification of a particular effect by its own influence on the process that gives rise to it. In positive feed back, the specific response that is obtained as a result of a process continue to increase as the process continues or increase, that is both the process and the effect generated increase.
Answer:
Peat is the surface organic layer of a soil that consists of partially decomposed organic matter, derived mostly from plant material, which has accumulated under conditions of waterlogging, oxygen deficiency, high acidity and nutrient deficiency
Explanation:
so c
The origin of life depends on a wide number of issues, all related to the existence of planetary and stellar bodies, chemical elements and the favorability of conditions for life created with such elements and under conditions not overly chaotic or disruptive and with energy sources that are balanced and moderate. As a result, the conditions for life can only result after the conditions of the universe are settled. It took the universe approximately 9.3 billion years to form galaxies and stars and planets that satisfy the demands of life on a fundamental level. It then took 4.5 billion years to condition the Earth through inorganic and organism progression to achieve the pinnacle of creation, which is humans.
Answer:
Oxygen
Explanation:
Oxygen is the last electron acceptor in the electron transport chain, which considers oxidative phosphorylation. Without oxygen, the electrons will be upheld, in the long run causing the electron transport chain to stop. This will make the results of glycolysis go through aging as opposed to going to the citrus extract cycle. Without oxygen, oxidative phosphorylation (the electron transport chain) is inconceivable, however substrate-level phosphorylation (glycolysis) proceeds.
Replication forkThe process by which DNA make copies of itself during cell
division is known as DNA replication. During DNA replication, the double helix
structure of DNA molecule is unzip by helicase enzyme which break the hydrogen
bond holding the complementary DNA base together. However, the separation of
the DNA strands will create Y shape called replication fork. Replication fork
will acts as template for creating new strands of DNA.
