Answer:
Lung
Explanation:
Lungs expand to pull oxygen into the body and contract to push it back out. The larynx is known as the voice box which is an air way passage to the lungs and a pharanx is membrane lined cavity behind the nose and mouth. Neither of these really expand or contact during inhalation so the answer is Lungs.
The three characteristics used to classify prokaryotes are shape, how they move, and how they get energy. Prokaryotes are unicellular or single celled organisms that lacks a membrane-bound nucleus, mitochondria, or any other membrane-bound organelles. Prokaryotes includes both bacteria and archaea and are found almost every where.
Answer:
The correct answer is D increasing the activity of protons pumps that lowers the pH of the cell walls allowing cells to elongate.
Explanation:
The plant growth hormone auxin work by increasing the H+ ion concentration thus decreasing the pH of the apoplast.
The decrease in the pH of the apoplast helps in the cell wall extension that ultimately result in cell growth.
Auxin hormone exert this effect by increasing the activity of increasing the activity of proton pumps in the apoplastic membrane.
Explanation:
Cells function differently in unicellular and multicellular organisms, but in every organism, each cell has specialized cell structures, or organelles, of which there are many. These organelles are responsible for a variety of cellular functions, such as obtaining nutrients, producing energy, and making proteins.
