The butterfly effect!
The butterfly effect is a popular phenomenon that has remained out of the scope for science. The very definition of the butterfly effect seems to be debatable. Tiny changes in the initial condition of a large non-linear system like the functioning of the brain or the ecosystem can cause huge changes in the system itself. Example, the flapping of the wings of the butterfly can cause tornado in some other place. Given the extremely high complexity of the problem, the study of the dynamics of such a change to happen has remained out of the scope of science.
Cell division happens twice during meiosis. One starting cell can produce for gametes (eggs or sperm.) In each round of division, cells go through four phases called prophase, metaphase, anaphase, and telophase.
prophase During prophase the chromosomes become visible as paired chromatids and the nuclear envelope disappears. This phase includes reduction division, which is where the number of chromosomes is decreased from 46 (diploid) to 23 (haploid.)
metaphase This is where the 23 remaining chromosomes become attached to the spindle fibers.
anaphase During this phase, the chromosomes move away from each other to one or the other pole of the spindle fiber.
telophase In which the chromatids or chromosomes move to opposite ends of the cell and two nuclei are formed.
interphase This is a resting period.
Answer: The electron transport chain.
Explanation:
Cellular respiration is defined as the mechanism by which living organisms converts organic substances from food such as glucose with the use of oxygen into energy-carrying biomolecules (e.g. adenosine triphosphate or ATP). There are different stages of cellular respiration which includes:
--> glycolysis,
--> pyruvate oxidation,
--> the citric acid or Krebs cycle, and
--> oxidative phosphorylation.
The oxidative phosphorylation also referred to as the ELECTRON TRANSPORT CHAIN occurs in the inner membrane of the mitochondria. It transfers electrons donated by the reduced electron carriers NADH and FADH2 (obtained from glycolysis, the citric acid cycle or fatty acid oxidation) through a series of electrons acceptors, to oxygen.
The electron transport chain is said to produces most of the energy which is 34 ATP molecules, as compared to only 2 ATP for glycolysis and 2 ATP for Krebs cycle.
The answer is ‘arteries are less flexible’. This is why the older you get the more predisposed you
are to cardiovascular diseases such as high blood
pressure. However, regular
exercise may delay this development. The barometers in the blood vessels also
become less sensitive hence these vessels become less responsive to blood
pressure changes.
