Metaphase is defined as the point at which all of the chromosome pairs are fully condensed, attached to the mitotic spindle, and aligned at the center—termed the metaphase plate.
What are the steps of metaphase?
- The chromosomes are all lined up at the center of the cell by the spindle during metaphase and are ready to divide.
- At the metaphase plate, all the chromosomes line up (not a physical structure, just a term for the plane where the chromosomes line up).
- The two kinetochores of each chromosome should be joined to microtubules coming from opposing spindle poles at this point.
- The cell will verify that all the chromosomes are at the metaphase plate and that their kinetochores are properly linked to microtubules before moving on to anaphase.
- The sister chromatids will split equally between the two daughter cells when the two cells separate in the following phase thanks to the spindle checkpoint, which is where it happens.
- A chromosome that is misaligned or improperly connected will prevent the cell from dividing unless the issue is resolved.

The reading of the blood pH value of 6.4 indicates a health issue because of the pH value. It is because the concentrations of H+ ions in the body becomes 10 times more than the usual level in the body.
The pH of the blood becomes less than 7.35 due to enhanced production of hydrogen ions by the body or the incapability of the body to produce bicarbonate ions in the kidney, the condition is known as metabolic acidosis that eventually results in acidemia.
True. Because the chemical messages are called hormones.
Answer: Energy at this point is stored as NADH
Explanation: Glycolysis is a catabolic reaction that is made of many steps that breaks down food to give off energy in a form of ATP. Pyruvate the product of glycolysis, is converted to Acetyl-coA using enzyme pryruvate dehydrogenase. During this process between krebs cycle and oxidative phosphorylation NAD takens electron (reduction) and turns to NADH(oxidation) which travels to the mitochondria, our power house, where its converted to energy using redox reactions. To sum up, energy from glucose molecules are transported and exist in forms of NAD to NADH.
