I would say that the brain stem would automatically send a message to the muscular rib cage & your diagphragm to make them work harder.
Hope this helps :))
False,your respiratory muscle expand each time when you exhale.
A phylogeny is an evolutionary ”tree” of related
organisms that can be constructed by using
information obtained from the genetic material.
Genetic information is contained in all living cells,
in the form of long DNA molecules that take the
shape of connected double- stranded spirals
(DNA stands for deoxyribonucleic acid). DNA
spirals, or “helixes”, are tightly compressed in the
nucleus of every cell. Their information is
organized into a code made up of four small
molecules — the building blocks of DNA. The
molecules, called nucleotides, are labelled:
A (adenine), C (cytosine), G (guanine) and T
(thymine).
It is possible to draw conclusions about the
evolution of a group of plant or animal species,
and the relationships among them, by comparing
selected pieces of DNA.
Essential amino acids are amino acids that must be supplied to one's body by their diet because they cannot be synthesized from scratch.
selective breeding has changed organisms over time by paring that organism up with another organism of its kind with desirable traits. take dogs for example, through selective breeding we now have many different types of dogs with different abilities. i hope this helps
