Explanation:

The pulse of the bodies raises for the first 20 seconds after sitting for a prolonged period of time and then to a standing position. It should, however, return to normal afterwards. The heartbeat of the body decreases because as you travel the blood needs to flow to the active areas and the blood flows downward from gravity, however you still need to pump blood to your brain. The rise in blood demand makes the heart pump more rapidly.

natta225 [31]

Answer:

The two species concepts that are most likely to place dogs and wolves together into a single species are biological and phylogenetic concepts.

Explanation:

The biological species concept establishes that a species is a group in a population whose individuals can mate and have viable, fertile descendence. These groups are also reproductively isolated from other groups or species. This is, the members of a species can not reproduce with the members of other species, or they can their progeny is unviable.

The phylogenetic species concept refers to a species as the monophyletic group that is less inclusive for organisms. It is a group of organisms that share an ancestor in common and can distinguish from other similar groups. In this concept, a unique species can include a wide phenotypic variability.

Identify a signal the brain sends out after the nervous system sends the signal that pH has dropped.

spin [16.1K]

In response to a notification of a decrease in blood pH by the nervous system, the brain sends signals to the external intercostal muscles and the diaphragm.

<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 decrease 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.
