What are the functions of the three types of openings in the model: openings in villi, alveoli, and the cell membrane?
Answer: These villi increase the surface area for more efficient food absorption. Within these villi, are present numerous blood vessels that absorb the digested food and carry it to the bloodstream. It is hence from the bloodstream, the absorbed food is delivered to each and every cell of the body.
The process of exchanging gases (carbon dioxide for oxygen) occurs at the lung alveoli. Alveoli are coated with a moist film that dissolves air in the lungs. Oxygen diffuses across the thin epithelium of the alveoli sacs into the blood within the surrounding capillaries.
In exocytosis, a cell releases substances into its environment. During exocytosis, vesicles that contain substances are moved to the cell membrane and fuse with it. This cell membrane function has three results: the total surface of the membrane increases, toxins or waste products are eliminated, and proteins become part of the plasma membrane.
Explanation:
thats all of the things for openings in villi the alveoli and the cell membrane
Answer:
blood picks up oxygen from the lung from tiny sacs called alveoli and transports it the cells where it enters the cell membrane
Explanation:
Which statement is accurate?
Layer C is younger than layer A.
Layer D has an older relative age than layer C.
If a geologic event tilted these layers, layer B would no longer be the oldest.
It is possible to determine the absolute age of layer C with the information given.
Answer:
A. Layer C is younger than layer A
Explanation:
As time goes on more and more rocks and sediment are laid down building up to be the diagram above. Because A is at the bottom that means it would have to be the first and oldest layer at that time.
how do the conductivities of solutions of ionic compounds and covalent compounds compare
Answer:
Ionic compounds are hard and crystal-like, while covalent compounds are softer and more flexible.
Explanation:
Ionic compounds are also more soluble in water than covalent compounds. This is because water dissolves polar substances, which is the consistency of the ionic compound, whereas covalent compounds are non-polar.
Hope this helps
If not... tell me
please help me out please
Answer:
Option B Is The Correct Answer
Explanation:
Prophase II: Now there are two daughter cells, each with 23 chromosomes (23 pairs of chromatids).
Metaphase II: In each of the two daughter cells the chromosomes (pair of sister chromatids) line up end-to-end along the equator of the cell.
Anaphase II.
Telophase II and cytokinesis.
