<h3>What is
blood pH?</h3>
Blood pH can be defined as a measure of the molar concentration of hydrogen ions that are present in the blood of a living organism, with respect to its acidity, neutrality or alkanlity (basicity).
In response to a notification of a <u>decrease</u> in blood pH by the nervous system, the brain would send signals (impulses) to the external intercostal muscles and the diaphragm through its respiratory center, so as to help the living organism increase its breathing rate and the volume of its lungs during inhalation.

Answer:
number 1 answer is 3.
number 2 energy is flowing upwards. ex grasshopper eats the grass, rat or whatever that is eats the grasshopper, and the hawk eats the rat. energy is going up each trophic level.
number 3. if the grass became polluted, then animals would get pollution in their bodies and at some point would die. eventually the grass would die too. primary consumers such as mouse, rabbit, grasshopper/snails would accumulate the most pollution because they directly eat the grass. whatever that is in the grass goes straight into their bodies.
"F many scientists conduct the same or similar experiments, and all obtain similar results a 'Scientific Law or Theory' can be written, which is a generally agreed-upon statement that explains and predicts how a natural phenomenon works
Answer: As matter cycles and energy flows through living systems and between living systems and the physical environment, matter and energy are conserved in each change. The carbon cycle provides an example of matter cycling and energy flow in ecosystems.
