Answer:
During quiet breathing, the main muscular effort is made in the inhalation process and the expiration process is mainly passive as it depends on the inhalation.
The expiration occurs due to the elastic recoil that causes a decrease in volume. In this process, the contraction of the diaphragm helps in the inhalation which is least affected by the intercostal muscle. During quiet breathing, the rate of inhalation and expiration time is relatively proportionate to one another.
Animals take oxygen from the air and exhale carbon dioxide. Plants use this carbon dioxide and release oxygen into the air. ... Photosynthesis is important to living organisms because it is plants that ultimately serve as a foundation for the food web by providing a major source of food for other living organisms.
The organelles and substances inside the organelles are smaller. On a molecular level a group that are smaller are hadrons, which are the group of particles that consist of protons and neutrons. Even smaller than hadrons are leptons, which consist of neutrinos, electons, and MANY others.
Explanation:
A gene-edited pig's heart has been transplanted into a human for the first time. The procedure is a one-off, and highly experimental, but the technique could help reduce transplant waiting lists in the future
