monitta

You will run and breathe heavily for a long period of time. is affecting your pH levels, Lowering the pH, making it more acidic.

  • A. Lowering the pH, making it more acidic.

<h3>How does respiratory rate affect pH?</h3>

When it is respiratory, it occurs due to an increase in the amount of volatile acids in the body, which lead to an increase in pCO2. When it is metabolic, it occurs due to the accumulation of non-volatile acids, which lead to the loss (excessive consumption) of bases, mainly bicarbonate, causing a drop in pH.

With this information, we can conclude that By eliminating carbon dioxide during expiration, pulmonary ventilation reduces the acidity of the blood, helping it to maintain the desired alkalinity level.

  3. Recycle toner and ink cartridges from empty printers, to avoid polluting rivers and streams.
  4. If possible buy remanufactured cartridges, avoiding environmental impact
  5. Recycle old newspapers, avoiding the death of more trees.

<h3>What is the evidence for evolution?</h3>

  1. Anatomy. Species may share similar physical features because those features were present in a common ancestor (homologous structures).
  2. Molecular biology. DNA and genetic code reflect the common ancestry of life

With this information, we can conclude that Ecology is concerned with the living beings on the planet and their relationships with each other and with the environment.
